Hi all,
This is the v2 of the pKVM selftest originally posted here [1].
Changes since v1:
- added support for testing NP guest transitions;
- added .data section in pKVM to allow using non-zero globals (needed
for previous point);
- dropped superfluous WARN() from __pkvm_host_share_guest() which is a
pain for testing;
- updated assertions for hyp/host transitions according to the
discussion on v1.
Patches based on v6.14-rc4, tested on Qemu.
