[PATCH v3 00/15] PMU-EBB support for PPC64 TCG

[Daniel Henrique Barboza <danielhb413@gmail.com>]

Hi,

This version contains changes suggested by David and Matheus. No big
design changes were made.


Changes from v2:
- former patch 1: merged into patch 2 (former 3)
- patches 1 and 2 (former 2 and 3):
  * no more intermediate write reg functions that will replaced shortly after
  * do not name specialized write callbacks with '_generic'
  * put the read/write MMCR0 ureg bits in a macro
- patch 3 (former 4): 
  * do not call 'helper_store_mmcr0' in spr_write_MMCR0_ureg
- patch 4 (former 5):
  * use extract64 when extracting MMCR1 events
- patch 5 (former 6):
  * MMCR0_FC is now represented in a DisasContext flag to avoid poking into
  registers before calling the instruction count helper
- patch 6 (former 7):
  * writing SPR_CTRL now forces a new translation block
- patch 8 (former 9):
  * rename device_tree rfebb format and argument
  * crop EBBRR when !msr_is_64bit
  * put the helper inside an "#if defined(TARGET_PPPC64)"
  * use gen_invalid() when CONFIG_USER_ONLY
