[LTP] [PATCH v2 0/3] KVM testing

[Martin Doucha]

Implement LTP infrastructure for tests which require executing a special
program inside KVM virtual machine. Basic test for CVE 2021-38198 written
using the KVM infrastrucutre (pagetable permission check bypass under software
emulated MMU) is included.

Martin Doucha (3):
  Add AX_CHECK_COMPILE_FLAG() autoconf macro
  KVM test infrastructure
  Add test for CVE 2021-38198
