[PATCH 0/3] fix emulation error on Windows bootup

[Jan Dakinevich]

This series intended to fix (again) a bug that was a subject of the 
following change:

  6ea6e84 ("KVM: x86: inject exceptions produced by x86_decode_insn")

Suddenly, that fix had a couple mistakes. First, ctxt->have_exception was 
not set if fault happened during instruction decoding. Second, returning 
value of inject_emulated_instruction was used to make the decision to 
reenter guest, but this could happen iff on nested page fault, that is not 
the scope where this bug could occur.

However, I have still deep doubts about 3rd commit in the series. Could
you please, make me an advise if it is the correct handling of guest page 
fault?

Jan Dakinevich (3):
  KVM: x86: fix wrong return code
  KVM: x86: set ctxt->have_exception in x86_decode_insn()
  KVM: x86: always stop emulation on page fault
