- When interrupt is not requested for VM86 call, make a fake exit point and
push the address onto stack as we do for INTn emulation. This avoids stack
underflow when we encounter RETF instruction in VM86 mode. Lack of this
exit point actually caused page fault in VM86 mode with VESA module when we
resume from suspend state[1].
- Remove unnecessary CLI and STI instructions from BIOS interrupt emulation.
INTn and IRET must be able to emulate the flag correctly.
