Subject: [PATCH v5 0/6] xen/PMU: PMU support for Xen PV(H) guests

I haven't posted Linux part of PV(H) VPMU support in a while but now
that (hopefully) the hypervisor part is getting close to be done I
think it's time to post it again.

There are very few differences compared to the last version, mostly due
to updates in shared structures layouts. Patches 1 and 4 have no changes
at all and patch 5 has minor changes due to rebasing so I kept David's
Reviewed-by tag.


Boris Ostrovsky (6):
  xen: xensyms support
  xen/PMU: Sysfs interface for setting Xen PMU mode
  xen/PMU: Initialization code for Xen PMU
  xen/PMU: Describe vendor-specific PMU registers
  xen/PMU: Intercept PMU-related MSR and APIC accesses
  xen/PMU: PMU emulation code
