+ This is a replacement for the following in-kernel drivers:
+ 1) gpio_keys (KEYBOARD_GPIO)
+ 2) gpio_keys_polled (KEYBOARD_GPIO_POLLED)
+
+ Instead of generating input events (like in-kernel drivers do) it generates
+ uevent-s and broadcasts them. This allows disabling input subsystem which is
+ an overkill for OpenWrt simple needs.

+shadowing the name.
+
+To reduce confusion and to allow the 'setup_max_cpus' value

+name for the function parameter name.

+Subject: [PATCH 1/2] compiler_types.h: Define __retain for

+
+Some code includes the __used macro to prevent functions and data from

+operates at the compiler and IR-level, and so still allows a linker to
+remove objects intended to be kept.
+
+Compilers supporting __attribute__((__retain__)) can address this gap by
+setting the flag SHF_GNU_RETAIN on the section of a function/variable,
+indicating to the linker the object should be retained. This attribute is
+available since gcc 11, clang 13, and binutils 2.36.
+
+Provide a __retain macro implementing __attribute__((__retain__)), whose
+first user will be the '__bpf_kfunc' tag.

+Subject: [PATCH 2/2] bpf: Harden __bpf_kfunc tag against linker kfunc removal
+
+BPF kfuncs are often not directly referenced and may be inadvertently
+removed by optimization steps during kernel builds, thus the __bpf_kfunc
+tag mitigates against this removal by including the __used macro. However,
+this macro alone does not prevent removal during linking, and may still
+yield build warnings (e.g. on mips64el):
+
+    LD      vmlinux
+    BTFIDS  vmlinux

+Update the __bpf_kfunc tag to better guard against linker optimization by

+With CONFIG_DMA_BOUNCE_UNALIGNED_KMALLOC enabled, the arm64 kernel still

+where necessary allows us to not include the bloated kernel.h. Making
+this implicit dependency on REPEAT_BYTE explicit allows for later
+improvements in the lib/string.c inclusion list.

+Subject: [PATCH] kernel.h: Move upper_*_bits() and lower_*_bits() to
+ wordpart.h
+
+The wordpart.h header is collecting APIs related to the handling
+parts of the word (usually in byte granularity). The upper_*_bits()
+and lower_*_bits() are good candidates to be moved to there.
+
+This helps to clean up header dependency hell with regard to kernel.h
+as the latter gathers completely unrelated stuff together and slows
+down compilation (especially when it's included into other header).

+Subject: [PATCH 1/4] mips: bmips: rework and cache CBR addr handling
+
+Rework the handling of the CBR address and cache it. This address
+doesn't change and can be cached instead of reading the register every
+time.
+
+This is in preparation of permitting to tweak the CBR address in DT with
+broken SoC or bootloader.
+
+bmips_cbr_addr is defined in setup.c for each arch to keep compatibility
+with legacy brcm47xx/brcm63xx and generic BMIPS target.

+Subject: [PATCH 3/4] mips: bmips: setup: make CBR address configurable
+
+Add support to provide CBR address from DT to handle broken
+SoC/Bootloader that doesn't correctly init it. This permits to use the
+RAC flush even in these condition.
+
+To provide a CBR address from DT, the property "brcm,bmips-cbr-reg"
+needs to be set in the "cpus" node. On DT init, this property presence
+will be checked and will set the bmips_cbr_addr value accordingly. Also
+bmips_rac_flush_disable will be set to false as RAC flush can be
+correctly supported.
+
+The CBR address from DT will overwrite the cached one and the
+one set in the CBR register will be ignored.
+
+Also the DT CBR address is validated on being outside DRAM window.

+
+Introduce device tree compatible 'linux,ubi' and attach compatible MTD
+devices using the MTD add notifier. This is needed for a UBI device to
+be available early at boot (and not only after late_initcall), so
+volumes on them can be used eg. as NVMEM providers for other drivers.

+Subject: [PATCH 5/8] mtd: ubi: introduce pre-removal notification for UBI
+ volumes
+
+Introduce a new notification type UBI_VOLUME_SHUTDOWN to inform users
+that a volume is just about to be removed.
+This is needed because users (such as the NVMEM subsystem) expect that
+at the time their removal function is called, the parenting device is
+still available (for removal of sysfs nodes, for example, in case of
+NVMEM which otherwise WARNs on volume removal).

+Look for the 'volumes' subnode of an MTD partition attached to a UBI
+device and attach matching child nodes to UBI volumes.
+This allows UBI volumes to be referenced in device tree, e.g. for use

+Subject: [PATCH 7/8] mtd: ubi: provide NVMEM layer over UBI volumes
+
+In an ideal world we would like UBI to be used where ever possible on a
+NAND chip. And with UBI support in ARM Trusted Firmware and U-Boot it
+is possible to achieve an (almost-)all-UBI flash layout. Hence the need
+for a way to also use UBI volumes to store board-level constants, such
+as MAC addresses and calibration data of wireless interfaces.
+
+Add UBI volume NVMEM driver module exposing UBI volumes as NVMEM
+providers. Allow UBI devices to have a "volumes" firmware subnode with
+volumes which may be compatible with "nvmem-cells".
+Access to UBI volumes via the NVMEM interface at this point is
+read-only, and it is slow, opening and closing the UBI volume for each
+access due to limitations of the NVMEM provider API.

+Subject: [PATCH 5/5] block: add support for partition table defined in OF
+
+Add support for partition table defined in Device Tree. Similar to how
+it's done with MTD, add support for defining a fixed partition table in
+device tree.
+
+A common scenario for this is fixed block (eMMC) embedded devices that
+have no MBR or GPT partition table to save storage space. Bootloader
+access the block device with absolute address of data.
+
+This is to complete the functionality with an equivalent implementation
+with providing partition table with bootargs, for case where the booargs
+can't be modified and tweaking the Device Tree is the only solution to
+have an usabe partition table.
+
+The implementation follow the fixed-partitions parser used on MTD
+devices where a "partitions" node is expected to be declared with
+"fixed-partitions" compatible in the OF node of the disk device
+(mmc-card for eMMC for example) and each child node declare a label
+and a reg with offset and size. If label is not declared, the node name
+is used as fallback. Eventually is also possible to declare the read-only
+property to flag the partition as read-only.

+Subject: [PATCH 1/4] net: Remove conditional threaded-NAPI wakeup based on
+ task state.
+
+A NAPI thread is scheduled by first setting NAPI_STATE_SCHED bit. If
+successful (the bit was not yet set) then the NAPI_STATE_SCHED_THREADED
+is set but only if thread's state is not TASK_INTERRUPTIBLE (is
+TASK_RUNNING) followed by task wakeup.
+
+If the task is idle (TASK_INTERRUPTIBLE) then the
+NAPI_STATE_SCHED_THREADED bit is not set. The thread is no relying on
+the bit but always leaving the wait-loop after returning from schedule()
+because there must have been a wakeup.
+
+The smpboot-threads implementation for per-CPU threads requires an
+explicit condition and does not support "if we get out of schedule()
+then there must be something to do".
+
+Removing this optimisation simplifies the following integration.
+
+Set NAPI_STATE_SCHED_THREADED unconditionally on wakeup and rely on it
+in the wait path by removing the `woken' condition.

+Subject: [PATCH 2/4] net: Allow to use SMP threads for backlog NAPI.
+
+Backlog NAPI is a per-CPU NAPI struct only (with no device behind it)
+used by drivers which don't do NAPI them self, RPS and parts of the
+stack which need to avoid recursive deadlocks while processing a packet.
+
+The non-NAPI driver use the CPU local backlog NAPI. If RPS is enabled
+then a flow for the skb is computed and based on the flow the skb can be
+enqueued on a remote CPU. Scheduling/ raising the softirq (for backlog's
+NAPI) on the remote CPU isn't trivial because the softirq is only
+scheduled on the local CPU and performed after the hardirq is done.
+In order to schedule a softirq on the remote CPU, an IPI is sent to the
+remote CPU which schedules the backlog-NAPI on the then local CPU.
+
+On PREEMPT_RT interrupts are force-threaded. The soft interrupts are
+raised within the interrupt thread and processed after the interrupt
+handler completed still within the context of the interrupt thread. The
+softirq is handled in the context where it originated.
+
+With force-threaded interrupts enabled, ksoftirqd is woken up if a
+softirq is raised from hardirq context. This is the case if it is raised
+from an IPI. Additionally there is a warning on PREEMPT_RT if the
+softirq is raised from the idle thread.
+This was done for two reasons:
+- With threaded interrupts the processing should happen in thread
+  context (where it originated) and ksoftirqd is the only thread for
+  this context if raised from hardirq. Using the currently running task
+  instead would "punish" a random task.
+- Once ksoftirqd is active it consumes all further softirqs until it
+  stops running. This changed recently and is no longer the case.
+
+Instead of keeping the backlog NAPI in ksoftirqd (in force-threaded/
+PREEMPT_RT setups) I am proposing NAPI-threads for backlog.
+The "proper" setup with threaded-NAPI is not doable because the threads
+are not pinned to an individual CPU and can be modified by the user.
+Additionally a dummy network device would have to be assigned. Also
+CPU-hotplug has to be considered if additional CPUs show up.
+All this can be probably done/ solved but the smpboot-threads already
+provide this infrastructure.
+
+Sending UDP packets over loopback expects that the packet is processed
+within the call. Delaying it by handing it over to the thread hurts
+performance. It is not beneficial to the outcome if the context switch
+happens immediately after enqueue or after a while to process a few
+packets in a batch.
+There is no need to always use the thread if the backlog NAPI is
+requested on the local CPU. This restores the loopback throuput. The
+performance drops mostly to the same value after enabling RPS on the
+loopback comparing the IPI and the tread result.
+
+Create NAPI-threads for backlog if request during boot. The thread runs
+the inner loop from napi_threaded_poll(), the wait part is different. It
+checks for NAPI_STATE_SCHED (the backlog NAPI can not be disabled).
+
+The NAPI threads for backlog are optional, it has to be enabled via the boot
+argument "thread_backlog_napi". It is mandatory for PREEMPT_RT to avoid the
+wakeup of ksoftirqd from the IPI.

+Subject: [PATCH 3/4] net: Use backlog-NAPI to clean up the defer_list.
+
+The defer_list is a per-CPU list which is used to free skbs outside of
+the socket lock and on the CPU on which they have been allocated.
+The list is processed during NAPI callbacks so ideally the list is
+cleaned up.
+Should the amount of skbs on the list exceed a certain water mark then
+the softirq is triggered remotely on the target CPU by invoking a remote
+function call. The raise of the softirqs via a remote function call
+leads to waking the ksoftirqd on PREEMPT_RT which is undesired.
+The backlog-NAPI threads already provide the infrastructure which can be
+utilized to perform the cleanup of the defer_list.
+
+The NAPI state is updated with the input_pkt_queue.lock acquired. It
+order not to break the state, it is needed to also wake the backlog-NAPI
+thread with the lock held. This requires to acquire the use the lock in
+rps_lock_irq*() if the backlog-NAPI threads are used even with RPS
+disabled.
+
+Move the logic of remotely starting softirqs to clean up the defer_list
+into kick_defer_list_purge(). Make sure a lock is held in
+rps_lock_irq*() if backlog-NAPI threads are used. Schedule backlog-NAPI
+for defer_list cleanup if backlog-NAPI is available.

+Subject: [PATCH 4/4] net: Rename rps_lock to backlog_lock.
+
+The rps_lock.*() functions use the inner lock of a sk_buff_head for
+locking. This lock is used if RPS is enabled, otherwise the list is
+accessed lockless and disabling interrupts is enough for the
+synchronisation because it is only accessed CPU local. Not only the list
+is protected but also the NAPI state protected.
+With the addition of backlog threads, the lock is also needed because of
+the cross CPU access even without RPS. The clean up of the defer_list
+list is also done via backlog threads (if enabled).
+
+It has been suggested to rename the locking function since it is no
+longer just RPS.
+
+Rename the rps_lock*() functions to backlog_lock*().

+Subject: [PATCH] udp: Allow GSO transmit from devices with no checksum offload
+
+Today sending a UDP GSO packet from a TUN device results in an EIO error:
+
+  import fcntl, os, struct
+  from socket import *
+
+  TUNSETIFF = 0x400454CA
+  IFF_TUN = 0x0001
+  IFF_NO_PI = 0x1000
+  UDP_SEGMENT = 103
+
+  tun_fd = os.open("/dev/net/tun", os.O_RDWR)
+  ifr = struct.pack("16sH", b"tun0", IFF_TUN | IFF_NO_PI)
+  fcntl.ioctl(tun_fd, TUNSETIFF, ifr)
+
+  os.system("ip addr add 192.0.2.1/24 dev tun0")
+  os.system("ip link set dev tun0 up")
+
+  s = socket(AF_INET, SOCK_DGRAM)
+  s.setsockopt(SOL_UDP, UDP_SEGMENT, 1200)
+  s.sendto(b"x" * 3000, ("192.0.2.2", 9)) # EIO
+
+This is due to a check in the udp stack if the egress device offers
+checksum offload. While TUN/TAP devices, by default, don't advertise this
+capability because it requires support from the TUN/TAP reader.
+
+However, the GSO stack has a software fallback for checksum calculation,
+which we can use. This way we don't force UDP_SEGMENT users to handle the
+EIO error and implement a segmentation fallback.
+
+Lift the restriction so that UDP_SEGMENT can be used with any egress
+device. We also need to adjust the UDP GSO code to match the GSO stack
+expectation about ip_summed field, as set in commit 8d63bee643f1 ("net:
+avoid skb_warn_bad_offload false positives on UFO"). Otherwise we will hit
+the bad offload check.
+
+Users should, however, expect a potential performance impact when
+batch-sending packets with UDP_SEGMENT without checksum offload on the
+egress device. In such case the packet payload is read twice: first during
+the sendmsg syscall when copying data from user memory, and then in the GSO
+stack for checksum computation. This double memory read can be less
+efficient than a regular sendmsg where the checksum is calculated during
+the initial data copy from user memory.

+Subject: [PATCH] net: Make USO depend on CSUM offload
+
+UDP segmentation offload inherently depends on checksum offload. It should
+not be possible to disable checksum offload while leaving USO enabled.
+Enforce this dependency in code.
+
+There is a single tx-udp-segmentation feature flag to indicate support for
+both IPv4/6, hence the devices wishing to support USO must offer checksum
+offload for both IP versions.

+Subject: [PATCH] udp: Fall back to software USO if IPv6 extension headers are
+ present
+
+In commit 10154dbded6d ("udp: Allow GSO transmit from devices with no
+checksum offload") we have intentionally allowed UDP GSO packets marked
+CHECKSUM_NONE to pass to the GSO stack, so that they can be segmented and
+checksummed by a software fallback when the egress device lacks these
+features.
+
+What was not taken into consideration is that a CHECKSUM_NONE skb can be
+handed over to the GSO stack also when the egress device advertises the
+tx-udp-segmentation / NETIF_F_GSO_UDP_L4 feature.
+
+This will happen when there are IPv6 extension headers present, which we
+check for in __ip6_append_data(). Syzbot has discovered this scenario,
+producing a warning as below:

+
+We are hitting the bad offload warning because when an egress device is
+capable of handling segmentation offload requested by
+skb_shinfo(skb)->gso_type, the chain of gso_segment callbacks won't produce
+any segment skbs and return NULL. See the skb_gso_ok() branch in
+{__udp,tcp,sctp}_gso_segment helpers.
+
+To fix it, force a fallback to software USO when processing a packet with
+IPv6 extension headers, since we don't know if these can checksummed by
+all devices which offer USO.

+Subject: [PATCH] page_pool: fragment API support for 32-bit arch with 64-bit
+ DMA
+
+Currently page_pool_alloc_frag() is not supported in 32-bit
+arch with 64-bit DMA because of the overlap issue between
+pp_frag_count and dma_addr_upper in 'struct page' for those
+arches, which seems to be quite common, see [1], which means
+driver may need to handle it when using fragment API.
+
+It is assumed that the combination of the above arch with an
+address space >16TB does not exist, as all those arches have
+64b equivalent, it seems logical to use the 64b version for a
+system with a large address space. It is also assumed that dma
+address is page aligned when we are dma mapping a page aligned
+buffer, see [2].
+
+That means we're storing 12 bits of 0 at the lower end for a
+dma address, we can reuse those bits for the above arches to
+support 32b+12b, which is 16TB of memory.
+
+If we make a wrong assumption, a warning is emitted so that
+user can report to us.

+Subject: [PATCH] page_pool: unify frag_count handling in
+ page_pool_is_last_frag()
+
+Currently when page_pool_create() is called with
+PP_FLAG_PAGE_FRAG flag, page_pool_alloc_pages() is only
+allowed to be called under the below constraints:
+1. page_pool_fragment_page() need to be called to setup
+   page->pp_frag_count immediately.
+2. page_pool_defrag_page() often need to be called to drain
+   the page->pp_frag_count when there is no more user will
+   be holding on to that page.
+
+Those constraints exist in order to support a page to be
+split into multi fragments.
+
+And those constraints have some overhead because of the
+cache line dirtying/bouncing and atomic update.
+
+Those constraints are unavoidable for case when we need a
+page to be split into more than one fragment, but there is
+also case that we want to avoid the above constraints and
+their overhead when a page can't be split as it can only
+hold a fragment as requested by user, depending on different
+use cases:
+use case 1: allocate page without page splitting.
+use case 2: allocate page with page splitting.
+use case 3: allocate page with or without page splitting
+            depending on the fragment size.
+
+Currently page pool only provide page_pool_alloc_pages() and
+page_pool_alloc_frag() API to enable the 1 & 2 separately,
+so we can not use a combination of 1 & 2 to enable 3, it is
+not possible yet because of the per page_pool flag
+PP_FLAG_PAGE_FRAG.
+
+So in order to allow allocating unsplit page without the
+overhead of split page while still allow allocating split
+page we need to remove the per page_pool flag in
+page_pool_is_last_frag(), as best as I can think of, it seems
+there are two methods as below:
+1. Add per page flag/bit to indicate a page is split or
+   not, which means we might need to update that flag/bit
+   everytime the page is recycled, dirtying the cache line
+   of 'struct page' for use case 1.
+2. Unify the page->pp_frag_count handling for both split and
+   unsplit page by assuming all pages in the page pool is split
+   into a big fragment initially.
+
+As page pool already supports use case 1 without dirtying the
+cache line of 'struct page' whenever a page is recyclable, we
+need to support the above use case 3 with minimal overhead,
+especially not adding any noticeable overhead for use case 1,
+and we are already doing an optimization by not updating
+pp_frag_count in page_pool_defrag_page() for the last fragment
+user, this patch chooses to unify the pp_frag_count handling
+to support the above use case 3.
+
+There is no noticeable performance degradation and some
+justification for unifying the frag_count handling with this
+patch applied using a micro-benchmark testing in [1].

+Subject: [PATCH] net: create a dummy net_device allocator
+
+It is impossible to use init_dummy_netdev together with alloc_netdev()
+as the 'setup' argument.
+
+This is because alloc_netdev() initializes some fields in the net_device
+structure, and later init_dummy_netdev() memzero them all. This causes
+some problems as reported here:
+
+	https://lore.kernel.org/all/20240322082336.49f110cc@kernel.org/
+
+Split the init_dummy_netdev() function in two. Create a new function called
+init_dummy_netdev_core() that does not memzero the net_device structure.
+Then have init_dummy_netdev() memzero-ing and calling
+init_dummy_netdev_core(), keeping the old behaviour.
+
+init_dummy_netdev_core() is the new function that could be called as an
+argument for alloc_netdev().
+
+Also, create a helper to allocate and initialize dummy net devices,
+leveraging init_dummy_netdev_core() as the setup argument. This function
+basically simplify the allocation of dummy devices, by allocating and
+initializing it. Freeing the device continue to be done through
+free_netdev()

+Subject: [PATCH 3/3] net: phy: aquantia: add firmware load support
+
+Aquantia PHY-s require firmware to be loaded before they start operating.
+It can be automatically loaded in case when there is a SPI-NOR connected
+to Aquantia PHY-s or can be loaded from the host via MDIO.
+
+This patch adds support for loading the firmware via MDIO as in most cases
+there is no SPI-NOR being used to save on cost.
+Firmware loading code itself is ported from mainline U-boot with cleanups.
+
+The firmware has mixed values both in big and little endian.
+PHY core itself is big-endian but it expects values to be in little-endian.
+The firmware is little-endian but CRC-16 value for it is stored at the end
+of firmware in big-endian.
+
+It seems the PHY does the conversion internally from firmware that is
+little-endian to the PHY that is big-endian on using the mailbox
+but mailbox returns a big-endian CRC-16 to verify the written data
+integrity.

+Subject: [PATCH 02/13] net: phy: at803x: move disable WOL to specific at8031
+ probe
+
+Move the WOL disable call to specific at8031 probe to make at803x_probe
+more generic and drop extra check for PHY ID.
+
+Keep the same previous behaviour by first calling at803x_probe and then
+disabling WOL.

+Subject: [PATCH 03/13] net: phy: at803x: raname hw_stats functions to qca83xx
+ specific name
+
+The function and the struct related to hw_stats were specific to qca83xx
+PHY but were called following the convention in the driver of calling
+everything with at803x prefix.
+
+To better organize the code, rename these function a more specific name
+to better describe that they are specific to 83xx PHY family.

+
+Move specific at8031 WOL enable/disable to dedicated function to make
+at803x_set_wol more generic.
+
+This is needed in preparation for PHY driver split as qca8081 share the
+same function to toggle WOL settings.
+
+In this new implementation WOL module in at8031 is enabled after the
+generic interrupt is setup. This should not cause any problem as the
+WOL_INT has a separate implementation and only relay on MAC bits.

+Subject: [PATCH 12/13] net: phy: at803x: move at8035 specific DT parse to
+ dedicated probe
+
+Move at8035 specific DT parse for clock out frequency to dedicated probe
+to make at803x probe function more generic.
+
+This is to tidy code and no behaviour change are intended.
+
+Detection logic is changed, we check if the clk 25m mask is set and if
+it's not zero, we assume the qca,clk-out-frequency property is set.
+
+The property is checked in the generic at803x_parse_dt called by
+at803x_probe.

+Subject: [PATCH 13/13] net: phy: at803x: drop specific PHY ID check from cable
+ test functions
+
+Drop specific PHY ID check for cable test functions for at803x. This is
+done to make functions more generic. While at it better describe what
+the functions does by using more symbolic function names.
+
+PHYs that requires to set additional reg are moved to specific function
+calling the more generic one.
+
+cdt_start and cdt_wait_for_completion are changed to take an additional
+arg to pass specific values specific to the PHY.

+Subject: [PATCH 2/2] net: phy: at803x: make read specific status function more
+ generic
+
+Rework read specific status function to be more generic. The function
+apply different speed mask based on the PHY ID. Make it more generic by
+adding an additional arg to pass the specific speed (ss) mask and use
+the provided mask to parse the speed value.
+
+This is needed to permit an easier deatch of qca808x code from the
+at803x driver.
