Merge tag 'fsnotify_for_v5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs

Pull fsnotify updates from Jan Kara:
 "This implements the fanotify FAN_DIR_MODIFY event.

  This event reports the name in a directory under which a change
  happened and together with the directory filehandle and fstatat()
  allows reliable and efficient implementation of directory
  synchronization"

70fbdfef4b sysfs: remove redundant __compat_only_sysfs_link_entry_to_kobj fn
Commit 9255782f70 ("sysfs: Wrap __compat_only_sysfs_link_entry_to_kobj
function to change the symlink name") made this function a wrapper
around a new non-underscored function, which is a bit odd.  The normal
naming convention is the other way around: the underscored function is
the wrappee, and the non-underscored function is the wrapper.

There's only one single user (well, two call-sites in that user) of the
more limited double underscore version of this function, so just remove
the oddly named wrapper entirely and just add the extra NULL argument to
the user.

I considered just doing that in the merge, but that tends to make
history really hard to read.

d38c07afc3 powerpc updates for 5.7
- A large series from Nick for 64-bit to further rework our exception vectors,
    and rewrite portions of the syscall entry/exit and interrupt return in C. The
    result is much easier to follow code that is also faster in general.
 
  - Cleanup of our ptrace code to split various parts out that had become badly
    intertwined with #ifdefs over the years.
 
  - Changes to our NUMA setup under the PowerVM hypervisor which should
    hopefully avoid non-sensical topologies which can lead to warnings from the
    workqueue code and other problems.
 
  - MAINTAINERS updates to remove some of our old orphan entries and update the
    status of others.
 
  - Quite a few other small changes and fixes all over the map.

aa1a8ce533 New tracing features:
- The ring buffer is no longer disabled when reading the trace file.
    The trace_pipe file was made to be used for live tracing and reading
    as it acted like the normal producer/consumer. As the trace file
    would not consume the data, the easy way of handling it was to just
    disable writes to the ring buffer. This came to a surprise to the
    BPF folks who complained about lost events due to reading.
    This is no longer an issue. If someone wants to keep the old disabling
    there's a new option "pause-on-trace" that can be set.
 
  - New set_ftrace_notrace_pid file. PIDs in this file will not be traced
    by the function tracer. Similar to set_ftrace_pid, which makes the
    function tracer only trace those tasks with PIDs in the file, the
    set_ftrace_notrace_pid does the reverse.
 
  - New set_event_notrace_pid file. PIDs in this file will cause events
    not to be traced if triggered by a task with a matching PID.
    Similar to the set_event_pid file but will not be traced.
    Note, sched_waking and sched_switch events may still be trace if
    one of the tasks referenced by those events contains a PID that
    is allowed to be traced.
 
 Tracing related features:
 
  - New bootconfig option, that is attached to the initrd file.
    If bootconfig is on the command line, then the initrd file
    is searched looking for a bootconfig appended at the end.
 
  - New GPU tracepoint infrastructure to help the gfx drivers to get
    off debugfs (acked by Greg Kroah-Hartman)
 
 Other minor updates and fixes.

Merge tag 'trace-v5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace

Pull tracing updates from Steven Rostedt:
 "New tracing features:

   - The ring buffer is no longer disabled when reading the trace file.

     The trace_pipe file was made to be used for live tracing and
     reading as it acted like the normal producer/consumer. As the trace
     file would not consume the data, the easy way of handling it was to
     just disable writes to the ring buffer.

     This came to a surprise to the BPF folks who complained about lost
     events due to reading. This is no longer an issue. If someone wants
     to keep the old disabling there's a new option "pause-on-trace"
     that can be set.

   - New set_ftrace_notrace_pid file. PIDs in this file will not be
     traced by the function tracer.

     Similar to set_ftrace_pid, which makes the function tracer only
     trace those tasks with PIDs in the file, the set_ftrace_notrace_pid
     does the reverse.

   - New set_event_notrace_pid file. PIDs in this file will cause events
     not to be traced if triggered by a task with a matching PID.

     Similar to the set_event_pid file but will not be traced. Note,
     sched_waking and sched_switch events may still be traced if one of
     the tasks referenced by those events contains a PID that is allowed
     to be traced.

  Tracing related features:

   - New bootconfig option, that is attached to the initrd file.

     If bootconfig is on the command line, then the initrd file is
     searched looking for a bootconfig appended at the end.

   - New GPU tracepoint infrastructure to help the gfx drivers to get
     off debugfs (acked by Greg Kroah-Hartman)

  And other minor updates and fixes"

Pull keyrings fixes from David Howells:
 "Here's a couple of patches that fix a circular dependency between
  holding key->sem and mm->mmap_sem when reading data from a key.

  One potential issue is that a filesystem looking to use a key inside,
  say, ->readpages() could deadlock if the key being read is the key
  that's required and the buffer the key is being read into is on a page
  that needs to be fetched.

  The case actually detected is a bit more involved - with a filesystem
  calling request_key() and locking the target keyring for write - which
  could be being read"

ddfd9dcf27 ACPI: PM: Add acpi_[un]register_wakeup_handler()
Since commit fdde0ff859 ("ACPI: PM: s2idle: Prevent spurious SCIs from
waking up the system") the SCI triggering without there being a wakeup
cause recognized by the ACPI sleep code will no longer wakeup the system.

This works as intended, but this is a problem for devices where the SCI
is shared with another device which is also a wakeup source.

In the past these, from the pov of the ACPI sleep code, spurious SCIs
would still cause a wakeup so the wakeup from the device sharing the
interrupt would actually wakeup the system. This now no longer works.

This is a problem on e.g. Bay Trail-T and Cherry Trail devices where
some peripherals (typically the XHCI controller) can signal a
Power Management Event (PME) to the Power Management Controller (PMC)
to wakeup the system, this uses the same interrupt as the SCI.
These wakeups are handled through a special INT0002 ACPI device which
checks for events in the GPE0a_STS for this and takes care of acking
the PME so that the shared interrupt stops triggering.

The change to the ACPI sleep code to ignore the spurious SCI, causes
the system to no longer wakeup on these PME events. To make things
worse this means that the INT0002 device driver interrupt handler will
no longer run, causing the PME to not get cleared and resulting in the
system hanging. Trying to wakeup the system after such a PME through e.g.
the power button no longer works.

Add an acpi_register_wakeup_handler() function which registers
a handler to be called from acpi_s2idle_wake() and when the handler
returns true, return true from acpi_s2idle_wake().

The INT0002 driver will use this mechanism to check the GPE0a_STS
register from acpi_s2idle_wake() and to tell the system to wakeup
if a PME is signaled in the register.

828907ef25 This is the bulk of GPIO development for the v5.7 kernel cycle.
Core and userspace API:
 
 - The userspace API KFIFOs have been imoproved with locks that
   do not block interrupts. This makes us better at getting
   events to userspace without blocking or disturbing new events
   arriving in the same time. This was reviewed by the KFIFO
   maintainer Stefani. This is a generic improvement which
   paves the road for similar improvements in other subsystems.
 
 - We provide a new ioctl() for monitoring changes in the line
   information, such as when multiple clients are taking lines
   and giving them back, possibly reconfiguring them in the
   process: we can now monitor that and not get stuck with stale
   static information.
 
 - An example tool 'gpio-watch' is provided to showcase this
   functionality.
 
 - Timestamps for events are switched to ktime_get_ns() which is
   monotonic. We previously had a 'realtime' stamp which could
   move forward and *backward* in time, which probably would just
   cause silent bugs and weird behaviour. In the long run we
   see two relevant timestamps: ktime_get_ns() or the timestamp
   sometimes provided by the GPIO hardware itself, if that
   exists.
 
 - Device Tree overlay support for GPIO hogs. On systems that
   load overlays, these overlays can now contain hogs, and will
   then be respected.
 
 - Handle pin control interaction with nonexisting pin ranges
   in the GPIO library core instead of in the individual
   drivers.
 
 New drivers:
 
 - New driver for the Mellanox BlueField 2 GPIO controller.
 
 Driver improvements:
 
 - Introduce the BGPIOF_NO_SET_ON_INPUT flag to the generic
   MMIO GPIO library and use this flag in the MT7621 driver.
 
 - Texas Instruments OMAP CPU power management improvements,
   such as blocking of idle on pending GPIO interrupts.

8c5c660529 nvme-fc: Revert "add module to ops template to allow module references"
The original patch was to resolve the lldd being able to be unloaded
while being used to talk to the boot device of the system. However, the
end result of the original patch is that any driver unload while a nvme
controller is live via the lldd is now being prohibited. Given the module
reference, the module teardown routine can't be called, thus there's no
way, other than manual actions to terminate the controllers.

Pull cgroup updates from Tejun Heo:

 - Christian extended clone3 so that processes can be spawned into
   cgroups directly.

   This is not only neat in terms of semantics but also avoids grabbing
   the global cgroup_threadgroup_rwsem for migration.

 - Daniel added !root xattr support to cgroupfs.

   Userland already uses xattrs on cgroupfs for bookkeeping. This will
   allow delegated cgroups to support such usages.

 - Prateek tried to make cpuset hotplug handling synchronous but that
   led to possible deadlock scenarios. Reverted.

 - Other minor changes including release_agent_path handling cleanup.

f6d2b802f8 Merge branch 'for-5.7/libnvdimm' into libnvdimm-for-next
- Introduce 'zero_page_range' as a dax operation. This facilitates
  filesystem-dax operation without a block-device.

- Advertise a persistence-domain for of_pmem and papr_scm. The
  persistence domain indicates where cpu-store cycles need to reach in
  the platform-memory subsystem before the platform will consider them
  power-fail protected.

- Fixup some flexible-array declarations.

  memory ranges, deploy that capability for the e820-pmem driver.

- Introduce phys_to_target_node() to facilitate drivers that want to
  know resulting numa node if a given reserved address range was

f605a263e0 dax, pmem: Add a dax operation zero_page_range
Add a dax operation zero_page_range, to zero a page. This will also clear any
known poison in the page being zeroed.

As of now, zeroing of one page is allowed in a single call. There
are no callers which are trying to zero more than a page in a single call.
Once we grow the callers which zero more than a page in single call, we
can add that support. Primary reason for not doing that yet is that this
will add little complexity in dm implementation where a range might be
spanning multiple underlying targets and one will have to split the range
into multiple sub ranges and call zero_page_range() on individual targets.

c657011431 remoteproc updates for v5.7
This introduces a range of improvements to the OMAP remoeteproc driver;
 among other things adding devicetree, suspend/resume and watchdog
 support, and adds support the remoteprocs in the DRA7xx SoC.
 
 It introduces support for 64-bit firmware, extends the ELF loader to
 support this and fixes for a number of race conditions in the recovery
 handling.
 
 It introduces a generic mechanism to allow remoteproc drivers to sync
 state with remote processors during a panic, and uses this to prepare
 Qualcomm remote processors for post mortem analysis.
 
 Finally it introduces fixes to cleanly recover from crashes in the modem
 firmware on production Qualcomm devices.

 KVM/MIPS has been broken since 5.5, it does not compile due to a patch committed

 prefer to fix it in generic code rather than KVM so they are taking care of it.

Pull exec/proc updates from Eric Biederman:
 "This contains two significant pieces of work: the work to sort out
  proc_flush_task, and the work to solve a deadlock between strace and
  exec.

  Fixing proc_flush_task so that it no longer requires a persistent
  mount makes improvements to proc possible. The removal of the
  persistent mount solves an old regression that that caused the hidepid
  mount option to only work on remount not on mount. The regression was
  found and reported by the Android folks. This further allows Alexey
  Gladkov's work making proc mount options specific to an individual
  mount of proc to move forward.

  The work on exec starts solving a long standing issue with exec that
  it takes mutexes of blocking userspace applications, which makes exec
  extremely deadlock prone. For the moment this adds a second mutex with
  a narrower scope that handles all of the easy cases. Which makes the
  tricky cases easy to spot. With a little luck the code to solve those
  deadlocks will be ready by next merge window"

commit beb4641a78 ("PCI: dwc: Add MSI-X callbacks handler"),
in order to raise MSI-X interrupt, obtained MSIX table address from
Base Address Register (BAR). However BAR only holds PCI address
programmed by the host whereas the MSI-X table should be in the local
memory.

Store the MSI-X table address (virtual address) as part of ->set_bar()
callback and use that to get the message address and message data
here.
