Do some minor housekeeping on the ioctl() macros, and then teach them
to detect and report when an ioctl() unexpectedly fails because KVM has
killed and/or bugged the VM.

Note, I'm 50/50 on whether or not the ARM patch is worthwhile, though I
spent a stupid amount of time on it (don't ask), so darn it I'm at least
posting it.

Oh, and the To: will probably show up funky, but I'd like to take this
through kvm-x86/selftests, not the ARM tree.

Thanks!

Sean Christopherson (4):
  KVM: selftests: Drop the single-underscore ioctl() helpers
  KVM: selftests: Add helper macros for ioctl()s that return file
    descriptors
  KVM: selftests: Use asserting kvm_ioctl() macros when getting ARM page
    sizes
  KVM: selftests: Add logic to detect if ioctl() failed because VM was
    killed
