[PATCH 0/2] Add missing trace points in emulator path

["Hou Wenlong" <houwenlong.hwl@antgroup.com>]

Some existed trace points are missing in emulator path, e.g.,
RDMSR/WRMSR emulation and CR read/write emulation. However,
if add those trace points in emulator common interfaces in
arch/x86/kvm/x86.c, other instruction emulation may use those
interfaces too and cause too much trace records. But add those
trace points in em_* functions in arch/x86/kvm/emulate.c seems
to be ugly. Luckily, RDMSR/WRMSR emulation uses a sepreate
interface, so add trace points for RDMSR/WRMSR in emulator
path is acceptable like normal path.

Hou Wenlong (2):
  KVM: x86: Return emulator error if RDMSR/WRMSR emulation failed
  KVM: x86: Add missing trace points for RDMSR/WRMSR in emulator path
