Pull compat mount cleanups from Al Viro:
"The last remnants of mount(2) compat buried by Christoph.
Buried into NFS, that is.
Generally I'm less enthusiastic about "let's use in_compat_syscall()
deep in call chain" kind of approach than Christoph seems to be, but
in this case it's warranted - that had been an NFS-specific wart,
hopefully not to be repeated in any other filesystems (read: any new
filesystem introducing non-text mount options will get NAKed even if
it doesn't mess the layout up).
IOW, not worth trying to grow an infrastructure that would avoid that
use of in_compat_syscall()..."

Pull EFI changes from Ingo Molnar:
- Preliminary RISC-V enablement - the bulk of it will arrive via the
RISCV tree.
- Relax decompressed image placement rules for 32-bit ARM
- Add support for passing MOK certificate table contents via a config
table rather than a EFI variable.
- Add support for 18 bit DIMM row IDs in the CPER records.
- Work around broken Dell firmware that passes the entire Boot####
variable contents as the command line
- Add definition of the EFI_MEMORY_CPU_CRYPTO memory attribute so we
can identify it in the memory map listings.
- Don't abort the boot on arm64 if the EFI RNG protocol is available
but returns with an error
- Replace slashes with exclamation marks in efivarfs file names
- Split efi-pstore from the deprecated efivars sysfs code, so we can
disable the latter on !x86.
- Misc fixes, cleanups and updates.

Pull arm64 updates from Will Deacon:
"There's quite a lot of code here, but much of it is due to the
addition of a new PMU driver as well as some arm64-specific selftests
which is an area where we've traditionally been lagging a bit.
In terms of exciting features, this includes support for the Memory
Tagging Extension which narrowly missed 5.9, hopefully allowing
userspace to run with use-after-free detection in production on CPUs
that support it. Work is ongoing to integrate the feature with KASAN
for 5.11.
Another change that I'm excited about (assuming they get the hardware
right) is preparing the ASID allocator for sharing the CPU page-table
with the SMMU. Those changes will also come in via Joerg with the
IOMMU pull.
We do stray outside of our usual directories in a few places, mostly
due to core changes required by MTE. Although much of this has been
Acked, there were a couple of places where we unfortunately didn't get
any review feedback.
Other than that, we ran into a handful of minor conflicts in -next,
but nothing that should post any issues.
Summary:
- Userspace support for the Memory Tagging Extension introduced by
Armv8.5. Kernel support (via KASAN) is likely to follow in 5.11.
- Selftests for MTE, Pointer Authentication and FPSIMD/SVE context
switching.
- Fix and subsequent rewrite of our Spectre mitigations, including
the addition of support for PR_SPEC_DISABLE_NOEXEC.
- Support for the Armv8.3 Pointer Authentication enhancements.
- Support for ASID pinning, which is required when sharing
page-tables with the SMMU.
- MM updates, including treating flush_tlb_fix_spurious_fault() as a
no-op.
- Perf/PMU driver updates, including addition of the ARM CMN PMU
driver and also support to handle CPU PMU IRQs as NMIs.
- Allow prefetchable PCI BARs to be exposed to userspace using normal
non-cacheable mappings.
- Implementation of ARCH_STACKWALK for unwinding.
- Improve reporting of unexpected kernel traps due to BPF JIT
failure.
- Improve robustness of user-visible HWCAP strings and their
corresponding numerical constants.
- Removal of TEXT_OFFSET.
- Removal of some unused functions, parameters and prototypes.
- Removal of MPIDR-based topology detection in favour of firmware
description.
- Cleanups to handling of SVE and FPSIMD register state in
preparation for potential future optimisation of handling across
syscalls.
- Cleanups to the SDEI driver in preparation for support in KVM.
- Miscellaneous cleanups and refactoring work"

Reply to the client with multiple hole and data segments. I use the
result of the first vfs_llseek() call for encoding as an optimization so
we don't have to immediately repeat the call. This also lets us encode
any remaining reply as data if we get an unexpected result while trying
to calculate a hole.

The original intent was presumably to reduce code duplication. The
trade-off was:
- No support for an NFSD proc function returning a non-success
RPC accept_stat value.
- No support for void NFS replies to non-NULL procedures.
- Everyone pays for the deduplication with a few extra conditional
branches in a hot path.
In addition, nfsd_dispatch() leaves *statp uninitialized in the
success path, unlike svc_generic_dispatch().
Address all of these problems by moving the logic for encoding
the NFS status code into the NFS XDR encoders themselves. Then
update the NFS .pc_func methods to return an RPC accept_stat
value.

Currently it calls pagevec_lookup_range_nr_tag(), but that may be
inefficient, as we might end up having to search several times as we get
down to looking for fewer pages to fill the array.
Thus spake Willy:
"I think ceph is misusing pagevec_lookup_range_nr_tag(). Let's suppose
you get a range which is AAAAbbbbAAAAbbbbAAAAbbbbbbbb(...)bbbbAAAA and
you try to fetch max_pages=13. First loop will get AAAAbbbbAAAAb and
have 8 locked_pages. The next call will get bbbAA and now
locked_pages=10. Next call gets AAb ... and now you're iterating your
way through all the 'b' one page at a time until you find that first A."
'A' here refers to pages that are eligible for writeback and 'b'
represents ones that aren't (for whatever reason).
Not capping the number of return pages may mean that we sometimes find
more pages than are needed, but the extra references will just get put
at the end.
Ceph is also the only caller of pagevec_lookup_range_nr_tag(), so this
change should allow us to eliminate that call as well. That will be done
in a follow-on patch.

In client for each inode, it may have many opened files and may
have been pinned in more than one MDS servers. And some inodes
are idle, which have no any opened files.
This patch will show these metrics in the debugfs, likes:
item total
-----------------------------------------
opened files / total inodes 14 / 5
pinned i_caps / total inodes 7 / 5
opened inodes / total inodes 3 / 5
Will send these metrics to ceph, which will be used by the `fs top`,
later.

This special casing was added in 7ce469a53e71 (ceph: fix splice
read for no Fc capability case). The confirm callback for ITER_PIPE
expects that the page is Uptodate and returns an error otherwise.
A simpler workaround is just to use the Uptodate bit, which has no
meaning for anonymous pages. Rip out the special casing for ITER_PIPE
and just SetPageUptodate before we copy to the iter.

Since nautilus, MDS tracks dirfrags whose child inodes have caps in open
file table. When MDS recovers, it prefetches all of these dirfrags. This
avoids using backtrace to load inodes. But dirfrags prefetch may load
lots of useless inodes into cache, and make MDS run out of memory.
Recent MDS adds an option that disables dirfrags prefetch. When dirfrags
prefetch is disabled. Recovering MDS only prefetches corresponding dir
inodes. Including inodes' parent/d_name in cap reconnect message can
help MDS to load inodes into its cache.
