Want to point out that this doesn't describe the *real* kvmarm stuff in
the original PR [*] and doesn't match what you had written in the merge
commit. Not sure what has gone wrong.

Used the wrong "git log --merges" incantation to generate the draft, 
which pulled in a message from the last merge commit in origin/master.

I have replaced the tag in place, but the commit is the same.  The new 
tag message is as follows:

---------------------------------
ARM:

* Fix EL2 Stage-1 MMIO mappings where a random address was used

* Fix SMCCC function number comparison when the SVE hint is set

RISC-V:

* Fix KVM_GET_REG_LIST API for ISA_EXT registers

* Fix reading ISA_EXT register of a missing extension

* Fix ISA_EXT register handling in get-reg-list test

* Fix filtering of AIA registers in get-reg-list test

x86:

* Fixes for TSC_AUX virtualization

* Stop zapping page tables asynchronously, since we don't
   zap them as often as before
