Linus,

The following changes since commit a5e13c6df0e41702d2b2c77c8ad41677ebb065b3:

  Linux 5.12-rc5 (2021-03-28 15:48:16 -0700)

  selftests: kvm: Check that TSC page value is small after KVM_SET_CLOCK(0) (2021-04-01 05:14:19 -0400)

It's a bit larger than I (and probably you) would like by the time we 
get to -rc6, but perhaps not entirely unexpected since the changes in
the last merge window were larger than usual.

The SVM fixes will cause conflicts in the next merge window, but I have
already tried a merge and just keeping the "new" (5.13) code will be
fine.

During the merge window I mentioned that I was considering a switch
of the default MMU around 5.12-rc3.  However, I am not going to do
this until at least 5.13.

----------------------------------------------------------------
x86:

* Fixes for missing TLB flushes with TDP MMU

* Fixes for race conditions in nested SVM

* Fixes for lockdep splat with Xen emulation

* Fix for kvmclock underflow

* Fix srcdir != builddir builds

* Other small cleanups

ARM:
* Fix GICv3 MMIO compatibility probing

* Prevent guests from using the ARMv8.4 self-hosted tracing extension
