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
