[PATCH v5 00/27] Implementing a MSHV (Microsoft Hypervisor) accelerator

[Paolo Bonzini <pbonzini@redhat.com>]

Hi Magnus,

this is your series with a lot of fixes to make it pass CI.  It's very
much untested but the changes are mostly concentrated in the headers,
where you obviously didn't have great coverage of target systems. :)

So I don't expect any huge issues, but anyway here it is for your testing.

The changes are:
- nits from Daniel's review
- add check for availability with --enable-whpx
- do not use __uN types outside linux-headers/
- add stubs in accel/stubs/mshv-stub.c
- do not include <linux/mshv.h> on files with Linux stubs
- split mshv.h/mshv_int.h to avoid conflicts with other accelerators
  (esp. in the definition of AccelCPUState)
- change first argument of mshv_request_interrupt to MshvState*
  (though it could go away altogether)
- fix double free of cpu->accel [Daniel]
- adjust for rename of qemu_wait_io_event()
- use MAX_CONST instead of MAX_SIZE
- adjust trace-events to use PRIx64

Thanks,

Paolo
