[Qemu-devel] [PATCH target-arm v3 0/8] target-arm: Extend PMCCNTR for ARMv8

[Peter Crosthwaite]

This patch series continues on from Alistairs original PMCCNTR patch
work. The counter is extended to 64-bit. Also adds support for the
PMCCFILTR_EL0 register which allows the counter to be
disabled based on the current EL

V3:
 -Tidy up the arm_ccnt_enabled()
 -Fixed an old commit message refering to the CCNT_ENABLED
  macro
 -Do EL change sync in pstate_write instead of in multiple
  code paths.
 -Addressed PMM V2 review
V2:
 -Fix some typos identified by Christopher Covington
 -Convert the CCNT_ENABLED macro to the arm_ccnt_enabled
  function
