[PATCH v2 0/5] hvf: stability fixes for HVF

[Cameron Esfahani via <qemu-devel@nongnu.org>]

The following patches fix stability issues with running QEMU on Apple
Hypervisor Framework (HVF):
- non-RAM, non-ROMD areas need to trap so accesses can be correctly
  emulated.
- Current TSC synchronization implementation is insufficient: when
  running with more than 1 core, TSC values can go backwards.  Until
  a correct implementation can be written, remove calls to
  hv_vm_sync_tsc().  Pass through TSC to guest OS.
- Fix REX emulation in relation to legacy prefixes.
- More correctly match SDM when setting CR0 and PDPTE registers.
- Save away exception type as well as vector in hvf_store_events() so
  they can be correctly reinjected in hvf_inject_interrupts().  Under
  heavy loads, exceptions got misrouted.

Changes in v2:
- Fix code style errors.

Cameron Esfahani (5):
  hvf: non-RAM, non-ROMD memory ranges are now correctly mapped in
  hvf: remove TSC synchronization code because it isn't fully complete
  hvf: correctly handle REX prefix in relation to legacy prefixes
  hvf: more accurately match SDM when setting CR0 and PDPTE registers
  hvf: save away type as well as vector so we can reinject them
