Subject: [GIT PULL] KVM changes for Linux 5.16-rc2
Linus,
The following changes since commit 84886c262ebcfa40751ed508268457af8a20c1aa:

KVM: x86: Cap KVM_CAP_NR_VCPUS by KVM_CAP_MAX_VCPUS (2021-11-18 02:12:15 -0500)
----------------------------------------------------------------
Selftest changes:
* Cleanups for the perf test infrastructure and mapping hugepages
* Avoid contention on mmap_sem when the guests start to run
* Add event channel upcall support to xen_shinfo_test
x86 changes:
* Fixes for Xen emulation
* Kill kvm_map_gfn() / kvm_unmap_gfn() and broken gfn_to_pfn_cache
* Fixes for migration of 32-bit nested guests on 64-bit hypervisor
* Compilation fixes
* More SEV cleanups
Generic:
* Cap the return value of KVM_CAP_NR_VCPUS to both KVM_CAP_MAX_VCPUS
and num_online_cpus(). Most architectures were only using one of the two.
----------------------------------------------------------------
I'll say in advance that I will have another largish pull request in rc3;
it's mostly due to a lot of review and new tests happening at the same
time and uncovering a bunch of related bugs. The gfn_to_pfn_cache thing
in the changelog above is one, next week I should finish preparing fixes
for APICv (old code) and SEV (new code). But after that, things should
calm down as the attention should shift to 5.17.
