x86/kvm: fix a missing-prototypes "vmread_error" (2020-04-02 15:17:45 -0400)

----------------------------------------------------------------
ARM:
* GICv4.1 support
* 32bit host removal

PPC:
* secure (encrypted) using under the Protected Execution Framework
ultravisor

s390:
* allow disabling GISA (hardware interrupt injection) and protected
VMs/ultravisor support.

x86:
* New dirty bitmap flag that sets all bits in the bitmap when dirty
page logging is enabled; this is faster because it doesn't require bulk
modification of the page tables.
* Initial work on making nested SVM event injection more similar to VMX,
and less buggy.
* Various cleanups to MMU code (though the big ones and related
optimizations were delayed to 5.8). Instead of using cr3 in function
names which occasionally means eptp, KVM too has standardized on "pgd".
* A large refactoring of CPUID features, which now use an array that
parallels the core x86_features.
* Some removal of pointer chasing from kvm_x86_ops, which will also be
switched to static calls as soon as they are available.
* New Tigerlake CPUID features.
* More bugfixes, optimizations and cleanups.

Generic:
* selftests: cleanups, new MMU notifier stress test, steal-time test
* CSV output for kvm_stat.

KVM/MIPS has been broken since 5.5, it does not compile due to a patch committed
by MIPS maintainers. I had already prepared a fix, but the MIPS maintainers
prefer to fix it in generic code rather than KVM so they are taking care of it.

----------------------------------------------------------------

The branch shows up as based on a random commit because of an ARM topic branch
that you have already merged. Most of it was developed as usual in the past couple of
months---no rebases or back merges here.

However, I also had 4 more patches to split a large file, but git hates
resolving that merge ("-X histogram" or "-X patience" make things a
little better, but not something that you shoud care about). I will
rebase those, retest, and send them separately.

Thanks,

Paolo
