Allow to defer the flushing of the TLB when unmapping pages, which allows
to reduce the numbers of IPI and the number of sfence.vma.
The ubenchmarch used in commit 43b3dfdd0455 ("arm64: support
batched/deferred tlb shootdown during page reclamation/migration") that
was multithreaded to force the usage of IPI shows good performance
improvement on all platforms:
* Unmatched: ~34%
* TH1520 : ~78%
* Qemu : ~81%
In addition, perf on qemu reports an important decrease in time spent
dealing with IPIs:
Before: 68.17% main [kernel.kallsyms] [k] __sbi_rfence_v02_call
After : 8.64% main [kernel.kallsyms] [k] __sbi_rfence_v02_call

Following the examples of cbom-block-size and cboz-block-size,
cbop-block-size is the cache size of Zicbop (cbo.prefetch) operations.
The most common case is to have all cache block sizes to be the same
size (e.g. profiles such as rva22u64 mandates a 64 bytes size for all
cache operations), but there's no specification requirement for that,
and an implementation can have different cache sizes for each operation.

The current description implies that only a single address translation
mode is available to the operating system. However, some implementations
support multiple address translation modes, and the operating system is
free to choose between them.
Per the RISC-V privileged specification, Sv48 implementations must also
implement Sv39, and likewise Sv57 implies support for Sv48. This means
it is possible to describe all supported address translation modes using
a single value, by naming the largest supported mode. This appears to
have been the intended usage of the property, so note it explicitly.

Introduce the first flag for the hwprobe syscall. The flag basically
reverses its behavior, i.e. instead of populating the values of keys
for a given set of cpus, the set of cpus after the call is the result
of finding a set which supports the values of the keys. In order to
do this, we implement a pair compare function which takes the type of
value (a single value vs. a bitmask of booleans) into consideration.
We also implement vdso support for the new flag.

The "count" parameter associated with the 'cpus' parameter of the
hwprobe syscall is the size in bytes of 'cpus'. Naming it 'cpu_count'
may mislead users (it did me) to think it's the number of CPUs that
are or can be represented by 'cpus' instead. This is particularly
easy (IMO) to get wrong since 'cpus' is documented to be defined by
CPU_SET(3) and CPU_SET(3) also documents a CPU_COUNT() (the number
of CPUs in set) macro. CPU_SET(3) refers to the size of cpu sets
with 'setsize'. Adopt 'cpusetsize' for the hwprobe parameter and
specifically state it is in bytes in Documentation/riscv/hwprobe.rst
to clarify.

- tracing: Fix to check the tracepoint event and return event at
parsing stage. The tracepoint event doesn't support %return but if
$retval exists, it will be converted to %return silently. This finds
that case and rejects it.

In /proc/cpuinfo, most of the information we show for each processor is
specific to that hart: marchid, mvendorid, mimpid, processor, hart,
compatible, and the mmu size. But the ISA string gets filtered through a
lowest common denominator mask, so that if one CPU is missing an ISA
extension, no CPUs will show it.
Now that we track the ISA extensions for each hart, let's report ISA
extension info accurately per-hart in /proc/cpuinfo. We cannot change
the "isa:" line, as usermode may be relying on that line to show only
the common set of extensions supported across all harts. Add a new "hart
isa" line instead, which reports the true set of extensions for that
hart.

Pull vfs fanotify fsid updates from Christian Brauner:
"This work is part of the plan to enable fanotify to serve as a drop-in
replacement for inotify. While inotify is availabe on all filesystems,
fanotify currently isn't.
In order to support fanotify on all filesystems two things are needed:
(1) all filesystems need to support AT_HANDLE_FID
(2) all filesystems need to report a non-zero f_fsid
This contains (1) and allows filesystems to encode non-decodable file
handlers for fanotify without implementing any exportfs operations by
encoding a file id of type FILEID_INO64_GEN from i_ino and
i_generation.
Filesystems that want to opt out of encoding non-decodable file ids
for fanotify that don't support NFS export can do so by providing an
empty export_operations struct.
This also partially addresses (2) by generating f_fsid for simple
filesystems as well as freevxfs. Remaining filesystems will be dealt
with by separate patches.
Finally, this contains the patch from the current exportfs maintainers
which moves exportfs under vfs with Chuck, Jeff, and Amir as
maintainers and vfs.git as tree"

git://git.kernel.org/pub/scm/linux/kernel/git/overlayfs/vfs
Pull overlayfs updates from Amir Goldstein:
- Overlayfs aio cleanups and fixes
Cleanups and minor fixes in preparation for factoring out of
read/write passthrough code.
- Overlayfs lock ordering changes
Hold mnt_writers only throughout copy up instead of a long lived
elevated refcount.
- Add support for nesting overlayfs private xattrs
There are cases where you want to use an overlayfs mount as a
lowerdir for another overlayfs mount. For example, if the system
rootfs is on overlayfs due to composefs, or to make it volatile (via
tmpfs), then you cannot currently store a lowerdir on the rootfs,
because the inner overlayfs will eat all the whiteouts and overlay
xattrs. This means you can't e.g. store on the rootfs a prepared
container image for use with overlayfs.
This adds support for nesting of overlayfs mounts by escaping the
problematic features and unescaping them when exposing to the
overlayfs user.
- Add new mount options for appending lowerdirs

Pull RTC updates from Alexandre Belloni:
"There is a new driver for the RTC of the Mstar SSD202D SoC. The
rtc7301 driver gains support for byte addresses to support the
USRobotics USR8200. Then we have many non user visible changes and
typo fixes.
Summary:
Subsytem:
- convert platform drivers to remove_new
- prevent modpost warnings for unremovable platform drivers
New driver:
- Mstar SSD202D
Drivers:
- brcmstb-waketimer: support level alarm_irq
- ep93xx: add DT support
- rtc7301: support byte-addressed IO"
