Since call_rcu, which is called in the hlist_for_each_entry_rcu traversal
of gtp_dellink, is not part of the RCU read critical section, it
is possible that the RCU grace period will pass during the traversal and

As with most architectures, allow handling of read faults in VMAs that
have VM_WRITE but without VM_READ (WRITE implies READ).
Otherwise, reading before writing a write-only memory will error while
reading after writing everything is fine.
BTW, move the VM_EXEC judgement before VM_READ/VM_WRITE to make logic a
little clearer.

During mode-2 reset, pci config space registers are affected at device
side. However, certain platforms have switches which assign virtual BAR
addresses and returns the same even after device is reset. This
affects pci_restore_state() as it doesn't issue another config write, if
the value read is same as the saved value.
Add a workaround to write saved config space values from driver side.
Presently, these switches are in platforms with SMU v13.0.6 SOCs, hence
restrict the workaround only to those.

Jonathan Heathcote reported a regression caused by blamed commit
on aarch64 architecture.
x86 happens to have irq-safe __this_cpu_add_return()
and __this_cpu_sub(), but this is not generic.
I think my confusion came from "struct sock" argument,
because these helpers are called with a locked socket.
But the memory accounting is per-proto (and per-cpu after
the blamed commit). We might cleanup these helpers later
to directly accept a "struct proto *proto" argument.
Switch to this_cpu_add_return() and this_cpu_xchg()
operations, and get rid of preempt_disable()/preempt_enable() pairs.
Fast path becomes a bit faster as a result :)

This commit was a pre-requisite for commit c1ccfcf1a9 ("NFSD:
Reschedule CB operations when backchannel rpc_clnt is shut down"),
which has already been reverted.
Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
The reverted commit attempted to enable NFSD to retransmit pending
callback operations if an NFS client disconnects, but
unintentionally introduces a hazardous behavior regression if the
client becomes permanently unreachable while callback operations are
still pending.
A disconnect can occur due to network partition or if the NFS server
needs to force the NFS client to retransmit (for example, if a GSS
window under-run occurs).
Reverting the commit will make NFSD behave the same as it did in
v6.8 and before. Pending callback operations are permanently lost if
the client connection is terminated before the client receives them.
For some callback operations, this loss is not harmful.
However, for CB_RECALL, the loss means a delegation might be revoked
unnecessarily. For CB_OFFLOAD, pending COPY operations will never
complete unless the NFS client subsequently sends an OFFLOAD_STATUS
operation, which the Linux NFS client does not currently implement.
These issues still need to be addressed somehow.

When KUnit tests are enabled, under very big kernel configurations
(e.g. `allyesconfig`), we can trigger a `rustdoc` ICE [1]:
RUSTDOC TK rust/kernel/lib.rs
error: the compiler unexpectedly panicked. this is a bug.
The reason is that this build step has a duplicated `@rustc_cfg` argument,
which contains the kernel configuration, and thus a lot of arguments. The
factor 2 happens to be enough to reach the ICE.
Thus remove the unneeded `@rustc_cfg`. By doing so, we clean up the
command and workaround the ICE.
The ICE has been fixed in the upcoming Rust 1.79 [2].

During module probe, regulator 'vin' and 'vdd-io' are used and enabled,
but the vdd-io regulator overwrites the 'vin' regulator pointer. During
remove, only the vdd-io is disabled, as the vin regulator pointer is not
available anymore. When regulator_put() is called during resource
cleanup a kernel warning is given, as the regulator is still enabled.
Store the two regulators in separate pointers and disable both the
regulators on module remove.

Current maintainer Douglas Miller has left IBM and no replacement has
been assigned for the driver. The eHEA hardware was last used on
IBM POWER7 systems, the last of which reached end-of-support at the
end of 2020.

- fix a few more deadlocks in recovery
- fix u32/u64 issues in mi_btree_bitmap
- btree key cache shrinker now actually frees, with more instrumentation
coming so we can verify that it's working correctly more easily in the
future

Pull bcachefs fixes from Kent Overstreet:
"Nothing too crazy in this one, and it looks like (fingers crossed) the
recovery and repair issues are settling down - although there's going
to be a long tail there, as we've still yet to really ramp up on error
injection or syzbot.
- fix a few more deadlocks in recovery
- fix u32/u64 issues in mi_btree_bitmap

With the recent PHYLINK changes requiring supported_interfaces to be set,
MV88E6250 family switches like the 88E6020 fail to probe - cmode is
never initialized on these devices, so mv88e6250_phylink_get_caps() does
not set any supported_interfaces flags.
Instead of a cmode, on 88E6250 we have a read-only port mode value that
encodes similar information. There is no reason to bother mapping port
mode to the cmodes of other switch models; instead we introduce a
mv88e6250_setup_supported_interfaces() that is called directly from
mv88e6250_phylink_get_caps().

commit 2f4a4d63a1 ("ACPI: CPPC: Use access_width over bit_width for system
memory accesses") modified cpc_read()/cpc_write() to use access_width to
read CPC registers.
However, for PCC registers the access width field in the ACPI register
macro specifies the PCC subspace ID. For non-zero PCC subspace ID it is
incorrectly treated as access width. This causes errors when reading
from PCC registers in the CPPC driver.
For PCC registers, base the size of read/write on the bit width field.
The debug message in cpc_read()/cpc_write() is updated to print relevant
information for the address space type used to read the register.

Commit 2f4a4d63a1 ("ACPI: CPPC: Use access_width over bit_width for
system memory accesses") neglected to properly wrap the bit_offset shift
when it comes to applying the mask. This may cause incorrect values to be
read and may cause the cpufreq module not be loaded.

Also, corrected the bitmask generation in GENMASK (extra bit being added).
