Subject: [PATCH 00/16] x86/vm-event: numerous adjustments & fixes
Date: Sat,  9 Jul 2016 07:11:49 +0300	[thread overview]
Message-ID: <1468037509-6428-1-git-send-email-czuzu@bitdefender.com> (raw)

Adjustments & fixes to the vm-events code, mostly monitor-related.
As I hadn't got the time/proper context to test these changes on a real machine,
for now please consider them only for review, I'll let you know when and how
actual testing went.

Thanks,

Corneliu ZUZU (16):
  x86/vmx_update_guest_cr: minor optimization
  x86: fix: make atomic_read() param const
  x86/monitor: mechanical renames
  x86/monitor: relocate vm_event_register_write_resume() function to
    monitor code

  x86/monitor: fix: set msr_bitmap to NULL after xfree
  x86/vm-event: fix: call cleanup when init fails, to free partial

  x86/vm-event: call monitor init & cleanup funcs from respective
    vm_event funcs
  arm/monitor: move d->monitor cleanup to monitor_cleanup_domain()
  x86/vm-event: centralize vcpu-destroy cleanup in vm-events code
  x86/monitor: fix: treat -monitor- properly, as a subsys of the
