The Fixes: tags indicate the original patches affected, but some

Jeremy Kerr b98e1a04e2 net: mctp: mark socks as dead on unhash, prevent re-add
Once a socket has been unhashed, we want to prevent it from being
re-used in a sk_key entry as part of a routing operation.

This change marks the sk as SOCK_DEAD on unhash, which prevents addition
into the net's key list.

We need to do this during the key add path, rather than key lookup, as
we release the net keys_lock between those operations.

Paolo Abeni 6e54ea37e3 net: mctp: hold key reference when looking up a general key
Currently, we have a race where we look up a sock through a "general"
(ie, not directly associated with the (src,dest,tag) tuple) key, then
drop the key reference while still holding the key's sock.

This change expands the key reference until we've finished using the
sock, and hence the sock reference too.

Jeremy Kerr 5f41ae6fca net: mctp: move expiry timer delete to unhash
Currently, we delete the key expiry timer (in sk->close) before
unhashing the sk. This means that another thread may find the sk through
its presence on the key list, and re-queue the timer.

This change moves the timer deletion to the unhash, after we have made
the key no longer observable, so the timer cannot be re-queued.

Jeremy Kerr de8a6b15d9 net: mctp: add an explicit reference from a mctp_sk_key to sock
Currently, we correlate the mctp_sk_key lifetime to the sock lifetime
through the sock hash/unhash operations, but this is pretty tenuous, and
there are cases where we may have a temporary reference to an unhashed
sk.

This change makes the reference more explicit, by adding a hold on the
sock when it's associated with a mctp_sk_key, released on final key
unref.

Kim Phillips 84168ae786 x86/cpu, kvm: Move X86_FEATURE_LFENCE_RDTSC to its native leaf
The LFENCE always serializing feature bit was defined as scattered
LFENCE_RDTSC and its native leaf bit position open-coded for KVM.  Add
it to its newly added CPUID leaf 0x80000021 EAX proper.  With
LFENCE_RDTSC in its proper place, the kernel's set_cpu_cap() will
effectively synthesize the feature for KVM going forward.

Also, DE_CFG[1] doesn't need to be set on such CPUs anymore.

Jani Nikula acc855d301 drm/i915/display: add intel_display_limits.h for key enums
Move a handful of key enums to a new file intel_display_limits.h. These
are the enum types, and the MAX/NUM enumerations within them, that are
used in other headers. Otherwise, there's no common theme between them.

Replace intel_display.h include with intel_display_limit.h where
relevant, and add the intel_display.h include directly in the .c files
where needed.

Since intel_display.h is used almost everywhere in display/, include it
from intel_display_types.h to avoid massive changes across the
board. There are very few files that would need intel_display_types.h
but not intel_display.h so this is neglible, and further cleanup between
these headers can be left for the future.

Overall this change drops the direct and indirect dependencies on
intel_display.h from about 300 to about 100 compilation units, because
we can drop the include from i915_drv.h.

Mark Pearson 1bc5d819f0 platform/x86: thinkpad_acpi: Fix profile modes on Intel platforms
My last commit to fix profile mode displays on AMD platforms caused
an issue on Intel platforms - sorry!

In it I was reading the current functional mode (MMC, PSC, AMT) from
the BIOS but didn't account for the fact that on some of our Intel
platforms I use a different API which returns just the profile and not
the functional mode.

This commit fixes it so that on Intel platforms it knows the functional
mode is always MMC.

I also fixed a potential problem that a platform may try to set the mode
for both MMC and PSC - which was incorrect.

Tested on X1 Carbon 9 (Intel) and Z13 (AMD).

Jens Axboe cb3ea4b767 x86/fpu: Don't set TIF_NEED_FPU_LOAD for PF_IO_WORKER threads
We don't set it on PF_KTHREAD threads as they never return to userspace,
and PF_IO_WORKER threads are identical in that regard. As they keep
running in the kernel until they die, skip setting the FPU flag on them.

More of a cosmetic thing that was found while debugging and
issue and pondering why the FPU flag is set on these threads.

Kim Phillips c35ac8c4bf KVM: x86: Move open-coded CPUID leaf 0x80000021 EAX bit propagation code
Move code from __do_cpuid_func() to kvm_set_cpu_caps() in preparation for adding
the features in their native leaf.

Also drop the bit description comments as it will be more self-describing once
the individual features are added.

Whilst there, switch to using the more efficient cpu_feature_enabled() instead
of static_cpu_has().

Note, LFENCE_RDTSC and "NULL selector clears base" are currently synthetic,
Linux-defined feature flags as Linux tracking of the features predates AMD's
definition.  Keep the manual propagation of the flags from their synthetic
counterparts until the kernel fully converts to AMD's definition, otherwise KVM
would stop synthesizing the flags as intended.
