Some of the existing drivers also add support for more hardware, such as Atmel SAMA 5D2 and Mediatek MT8183.

epoll: add syscall epoll_pwait2
Add syscall epoll_pwait2, an epoll_wait variant with nsec resolution that
replaces int timeout with struct timespec. It is equivalent otherwise.
int epoll_pwait2(int fd, struct epoll_event *events,
int maxevents,
const struct timespec *timeout,
const sigset_t *sigset);
The underlying hrtimer is already programmed with nsec resolution.
pselect and ppoll also set nsec resolution timeout with timespec.
The sigset_t in epoll_pwait has a compat variant. epoll_pwait2 needs
the same.
For timespec, only support this new interface on 2038 aware platforms
that define __kernel_timespec_t. So no CONFIG_COMPAT_32BIT_TIME.

epoll: convert internal api to timespec64
Patch series "add epoll_pwait2 syscall", v4. Enable nanosecond timeouts for epoll. Analogous to pselect and ppoll, introduce an epoll_wait syscall variant that takes a struct timespec instead of int timeout. This patch (of 4): Make epoll more consistent with select/poll: pass along the timeout as timespec64 pointer. In anticipation of additional changes affecting all three polling mechanisms: - add epoll_pwait2 syscall with timespec semantics, and share poll_select_set_timeout implementation. - compute slack before conversion to absolute time, to save one ktime_get_ts64 call.

epoll: eliminate unnecessary lock for zero timeout
We call ep_events_available() under lock when timeout is 0, and then call
it without locks in the loop for the other cases.
Instead, call ep_events_available() without lock for all cases. For
non-zero timeouts, we will recheck after adding the thread to the wait
queue. For zero timeout cases, by definition, user is opportunistically
polling and will have to call epoll_wait again in the future.
Note that this lock was kept in

epoll: simplify and optimize busy loop logic
ep_events_available() is called multiple times around the busy loop logic, even though the logic is generally not used. ep_reset_busy_poll_napi_id() is similarly always called, even when busy loop is not used. Eliminate ep_reset_busy_poll_napi_id() and inline it inside ep_busy_loop(). Make ep_busy_loop() return whether there are any events available after the busy loop. This will eliminate unnecessary loads and branches, and simplifies the loop.

epoll: pull fatal signal checks into ep_send_events()
To simplify the code, pull in checking the fatal signals into ep_send_events(). ep_send_events() is called only from ep_poll(). Note that, previously, we were always checking fatal events, but it is checked only if eavail is true. This should be fine because the goal of that check is to quickly return from epoll_wait() when there is a pending fatal signal.

epoll: check for events when removing a timed out thread from the wait queue
Patch series "simplify ep_poll". This patch series is a followup based on the suggestions and feedback by Linus: https://lkml.kernel.org/r/CAHk-=wizk=OxUyQPbO8MS41w2Pag1kniUV5WdD5qWL-gq1kjDA@mail.gmail.com The first patch in the series is a fix for the epoll race in presence of timeouts, so that it can be cleanly backported to all affected stable kernels. The rest of the patch series simplify the ep_poll() implementation. Some of these simplifications result in minor performance enhancements as well. We have kept these changes under self tests and internal benchmarks for a few days, and there are minor (1-2%) performance enhancements as a result. This patch (of 8): After |

mm, kvm: account kvm_vcpu_mmap to kmemcg
A VCPU of a VM can allocate couple of pages which can be mmap'ed by the user space application. At the moment this memory is not charged to the memcg of the VMM. On a large machine running large number of VMs or small number of VMs having large number of VCPUs, this unaccounted memory can be very significant. So, charge this memory to the memcg of the VMM. Please note that lifetime of these allocations corresponds to the lifetime of the VMM.

mm/filemap: fix infinite loop in generic_file_buffered_read()
If iter->count is 0 and iocb->ki_pos is page aligned, this causes nr_pages to be 0. Then in generic_file_buffered_read_get_pages() find_get_pages_contig() returns 0 - because we asked for 0 pages, so we call generic_file_buffered_read_no_cached_page() which attempts to add a page to the page cache, which fails with -EEXIST, and then we loop.

New code for 5.11:
- Introduce a "needsrepair" "feature" to flag a filesystem as needing a
pass through xfs_repair. This is key to enabling filesystem upgrades
(in xfs_db) that require xfs_repair to make minor adjustments to metadata.
- Refactor parameter checking of recovered log intent items so that we
actually use the same validation code as them that generate the intent
items.
- Various fixes to online scrub not reacting correctly to directory
entries pointing to inodes that cannot be igetted.
- Refactor validation helpers for data and rt volume extents.
- Refactor XFS_TRANS_DQ_DIRTY out of existence.
- Fix a longstanding bug where mounting with "uqnoenforce" would start
user quotas in non-enforcing mode but /proc/mounts would display
"usrquota", implying that they are being enforced.
- Don't flag dax+reflink inodes as corruption since that is a valid (but
not fully functional) combination right now.
- Clean up raid stripe validation functions.
- Refactor the inode allocation code to be more straightforward.
- Small prep cleanup for idmapping support.
- Get rid of the xfs_buf_t typedef.

RISC-V Patches for the 5.11 Merge Window, Part 1
We have a handful of new kernel features for 5.11:
* Support for the contiguous memory allocator.
* Support for IRQ Time Accounting
* Support for stack tracing
* Support for strict /dev/mem
* Support for kernel section protection
I'm being a bit conservative on the cutoff for this round due to the
timing, so this is all the new development I'm going to take for this
cycle (even if some of it probably normally would have been OK). There
are, however, some fixes on the list that I will likely be sending along
either later this week or early next week.
There is one issue in here: one of my test configurations
(PREEMPT{,_DEBUG}=y) fails to boot on QEMU 5.0.0 (from April) as of the
.text.init alignment patch. With any luck we'll sort out the issue, but
given how many bugs get fixed all over the place and how unrelated those
features seem my guess is that we're just running into something that's
been lurking for a while and has already been fixed in the newer QEMU
(though I wouldn't be surprised if it's one of these implicit
assumptions we have in the boot flow). If it was hardware I'd be
strongly inclined to look more closely, but given that users can upgrade
their simulators I'm less worried about it.
There are two merge conflicts, both in build files. They're both a bit
clunky: arch/riscv/Kconfig is out of order (I have a script that's
supposed to keep them in order, I'll fix it) and lib/Makefile is out of
order (though GENERIC_LIB here doesn't mean quite what it does above).

drm/i915: Fix mismatch between misplaced vma check and vma insert
When inserting a VMA, we restrict the placement to the low 4G unless the caller opts into using the full range. This was done to allow usersapce the opportunity to transition slowly from a 32b address space, and to avoid breaking inherent 32b assumptions of some commands. However, for insert we limited ourselves to 4G-4K, but on verification we allowed the full 4G. This causes some attempts to bind a new buffer to sporadically fail with -ENOSPC, but at other times be bound successfully. commit |

This is the bulk of the GPIO changes for the v5.11 kernel cycle:
Core changes:
- Retired the old set-up function for GPIO IRQ chips. All chips
now use the template struct gpio_irq_chip and pass that to the core
to be set up alongside the gpio_chip. We can finally get rid of
the old cruft.
- Some refactoring and clean up of the core code.
- Support edge event timestamps to be stamped using REALTIME
(wall clock) timestamps. We have found solid use cases for
this, so we support it.
New drivers:
- MStar MSC313 GPIO driver.
- HiSilicon GPIO driver.
Driver improvements:
- The PCA953x driver now also supports the NXP PCAL9554B/C chips.
- The mockup driver can now be probed from the device tree which
is pretty useful for virtual prototyping of devices.
- The Rcar driver now supports .get_multiple()
- The MXC driver dropped some legacy and became a pure device
tree client.
- The Exar driver was moved over to the IDA interface for
enumerating, and also switched over to using regmap for
register access.

Tracing updates for 5.11
The major update to this release is that there's a new arch config option called: CONFIG_HAVE_DYNAMIC_FTRACE_WITH_ARGS. Currently, only x86_64 enables it. All the ftrace callbacks now take a struct ftrace_regs instead of a struct pt_regs. If the architecture has HAVE_DYNAMIC_FTRACE_WITH_ARGS enabled, then the ftrace_regs will have enough information to read the arguments of the function being traced, as well as access to the stack pointer. This way, if a user (like live kernel patching) only cares about the arguments, then it can avoid using the heavier weight "regs" callback, that puts in enough information in the struct ftrace_regs to simulate a breakpoint exception (needed for kprobes). New config option that audits the timestamps of the ftrace ring buffer at most every event recorded. The "check_buffer()" calls will conflict with mainline, because I purposely added the check without including the fix that it caught, which is in mainline. Running a kernel built from the commit of the added check will trigger it. Ftrace recursion protection has been cleaned up to move the protection to the callback itself (this saves on an extra function call for those callbacks). Perf now handles its own RCU protection and does not depend on ftrace to do it for it (saving on that extra function call). New debug option to add "recursed_functions" file to tracefs that lists all the places that triggered the recursion protection of the function tracer. This will show where things need to be fixed as recursion slows down the function tracer. The eval enum mapping updates done at boot up are now offloaded to a work queue, as it caused a noticeable pause on slow embedded boards. Various clean ups and last minute fixes. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCX9uq8xQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qtrwAQCHevqWMjKc1Q76bnCgwB0AbFKB6vqy 5b6g/co5+ihv8wD/eJPWlZMAt97zTVW7bdp5qj/GTiCDbAsODMZ597LsxA0= =rZEz -----END PGP SIGNATURE----- Merge tag 'trace-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: "The major update to this release is that there's a new arch config option called CONFIG_HAVE_DYNAMIC_FTRACE_WITH_ARGS.

Modules updates for v5.11
Summary of modules changes for the 5.11 merge window:
- Fix a race condition between systemd/udev and the module loader.
The module loader was sending a uevent before the module was fully
initialized (i.e., before its init function has been called). This means
udev can start processing the module uevent before the module has
finished initializing, and some udev rules expect that the module has
initialized already upon receiving the uevent. This resulted in some
systemd mount units failing if udev processes the event faster than the
module can finish init. This is fixed by delaying the uevent until after
the module has called its init routine.
- Make the linker array sections for kernel params and module version
attributes more robust by switching to use the alignment of the type in
question. Namely, linker section arrays will be constructed using the
alignment required by the struct (using __alignof__()) as opposed to a
specific value such as sizeof(void *) or sizeof(long). This is less
likely to cause breakages should the size of the type ever change (from
Johan Hovold)
- Fix module state inconsistency by setting it back to GOING when a module
fails to load and is on its way out (from Miroslav Benes)
- Some comment and code cleanups (from Sergey Shtylyov)
