Linus,

Merge remote-tracking branch 'kvm/queue' into HEAD (2022-12-09 09:15:09 +0100)


There are a few non-KVM changes here:

- introduce FOLL_INTERRUPTIBLE, reviewed by the mm/ people;

- tools/perf: change set_bit to __set_bit etc. in preparation for
introducing atomic bit operations, acked by perf maintainers;

- a shared topic branch with ARM to introduce automatic generation of
the system register headers, so you probably want to pull from Catalin
first;

- MTE work that the ARM folks routed through Marc Zyngier's KVM tree. This
also touches mm/ and fs/proc/page.c, in order to introduce a PG_arch_3
flag, only for 64-bit machines. The core ARM parts can be found at
https://lore.kernel.org/all/20220705142619.4135905-1-catalin.marinas@xxxxxxx/
if you're interested in the list of affected files; they were later
rebased and extended with the KVM bits. Note that this is *not*
a shared topic branch.

----------------------------------------------------------------
ARM64:

* Enable the per-vcpu dirty-ring tracking mechanism, together with an
option to keep the good old dirty log around for pages that are
dirtied by something other than a vcpu.

* Switch to the relaxed parallel fault handling, using RCU to delay
page table reclaim and giving better performance under load.

* Relax the MTE ABI, allowing a VMM to use the MAP_SHARED mapping option,
which multi-process VMMs such as crosvm rely on. Includes a shared
topic branch with the ARM tree (see merge commit 382b5b87a97d:
"Fix a number of issues with MTE, such as races on the tags being
initialised vs the PG_mte_tagged flag as well as the lack of support
for VM_SHARED when KVM is involved. Patches from Catalin Marinas and
Peter Collingbourne").

* Merge the pKVM shadow vcpu state tracking that allows the hypervisor
to have its own view of a vcpu, keeping that state private.

* Add support for the PMUv3p5 architecture revision, bringing support
for 64bit counters on systems that support it, and fix the
no-quite-compliant CHAIN-ed counter support for the machines that
actually exist out there.

* Fix a handful of minor issues around 52bit VA/PA support (64kB pages
only) as a prefix of the oncoming support for 4kB and 16kB pages.

* Pick a small set of documentation and spelling fixes, because no
good merge window would be complete without those.

s390:

* Second batch of the lazy destroy patches

* First batch of KVM changes for kernel virtual != physical address support

* Removal of a unused function

x86:

* Allow compiling out SMM support

* Cleanup and documentation of SMM state save area format

* Preserve interrupt shadow in SMM state save area

* Respond to generic signals during slow page faults

* Fixes and optimizations for the non-executable huge page errata fix.

* Reprogram all performance counters on PMU filter change

* Cleanups to Hyper-V emulation and tests

* Process Hyper-V TLB flushes from a nested guest (i.e. from a L2 guest
running on top of a L1 Hyper-V hypervisor)

* Advertise several new Intel features

* x86 Xen-for-KVM:

** Allow the Xen runstate information to cross a page boundary

** Allow XEN_RUNSTATE_UPDATE flag behaviour to be configured

** Add support for 32-bit guests in SCHEDOP_poll

* Notable x86 fixes and cleanups:

** One-off fixes for various emulation flows (SGX, VMXON, NRIPS=0).

** Reinstate IBPB on emulated VM-Exit that was incorrectly dropped a few
years back when eliminating unnecessary barriers when switching between
vmcs01 and vmcs02.

** Clean up vmread_error_trampoline() to make it more obvious that params
must be passed on the stack, even for x86-64.

** Let userspace set all supported bits in MSR_IA32_FEAT_CTL irrespective
of the current guest CPUID.

** Fudge around a race with TSC refinement that results in KVM incorrectly
thinking a guest needs TSC scaling when running on a CPU with a
constant TSC, but no hardware-enumerated TSC frequency.

** Advertise (on AMD) that the SMM_CTL MSR is not supported

** Remove unnecessary exports

Generic:

* Support for responding to signals during page faults; introduces
new FOLL_INTERRUPTIBLE flag that was reviewed by mm folks

Selftests:

* Fix an inverted check in the access tracking perf test, and restore
support for asserting that there aren't too many idle pages when
running on bare metal.

* Fix build errors that occur in certain setups (unsure exactly what is
unique about the problematic setup) due to glibc overriding
static_assert() to a variant that requires a custom message.

* Introduce actual atomics for clear/set_bit() in selftests

* Add support for pinning vCPUs in dirty_log_perf_test.

* Rename the so called "perf_util" framework to "memstress".

* Add a lightweight psuedo RNG for guest use, and use it to randomize
the access pattern and write vs. read percentage in the memstress tests.

* Add a common ucall implementation; code dedup and pre-work for running
SEV (and beyond) guests in selftests.

* Provide a common constructor and arch hook, which will eventually be
used by x86 to automatically select the right hypercall (AMD vs. Intel).

* A bunch of added/enabled/fixed selftests for ARM64, covering memslots,
breakpoints, stage-2 faults and access tracking.

* x86-specific selftest changes:

** Clean up x86's page table management.

** Clean up and enhance the "smaller maxphyaddr" test, and add a related
test to cover generic emulation failure.

** Clean up the nEPT support checks.

** Add X86_PROPERTY_* framework to retrieve multi-bit CPUID values.

** Fix an ordering issue in the AMX test introduced by recent conversions
to use kvm_cpu_has(), and harden the code to guard against similar bugs
in the future. Anything that tiggers caching of KVM's supported CPUID,
kvm_cpu_has() in this case, effectively hides opt-in XSAVE features if
the caching occurs before the test opts in via prctl().

Documentation:

* Remove deleted ioctls from documentation

* Clean up the docs for the x86 MSR filter.

* Various fixes
