[kvm-unit-tests PATCH v3 0/7] x86: Illegal LEA test and FEP cleanups

[Sean Christopherson <seanjc@google.com>]

Slightly reworked version of Michal's series clean up the FEP mess and add
a testcase for illegal LEA.  Core ideas are all the same, just moved the
common FEP functionality to desc.h to make it easier to use in other tests.

v3:
 - Define __ASM_SEL/__ASM_FORM in desc.h to fix circular dependency.
 - Move ASM_TRY_FEP() to desc.h
 - Add is_fep_available() helper to simplify probing FEP.
 - Use is_fep_available() in PMU test.

Michal Luczaj (4):
  x86: emulator.c: Save and restore exception handlers
  x86: Introduce ASM_TRY_FEP() to handle exceptions on forced emulation
  x86: emulator.c: Use ASM_TRY() for the UD_VECTOR cases
  x86: Test emulator's handling of LEA with /reg

Sean Christopherson (3):
  x86: Dedup 32-bit vs. 64-bit ASM_TRY() by stealing kernel's
    __ASM_SEL()
  x86: Add helper to detect if forced emulation prefix is available
  x86/pmu: Run the "emulation" test iff forced emulation is available
