Commit Message

Yi Sun Oct. 8, 2017, 7:23 a.m. UTC 
This patch renames 'cbm_type' to 'psr_type' to generalize it.
Then, we can reuse this for all psr allocation features.

v5:
    - correct character of reviewer's name.
      (suggested by Jan Beulich)
v4:
    - fix words in commit message.
      (suggested by Roger Pau Monné)
v3:
    - replace 'psr_val_type' to 'psr_type' and remove '_VAL' from the enum
      items.
      (suggested by Roger Pau Monné)
v2:
    - replace 'PSR_VAL_TYPE_{L3, L2}' to 'PSR_VAL_TYPE_{L3, L2}_CBM'.
      (suggested by Chao Peng)
