[PATCH v2 0/3] Add support for SPE Data Source packet on HiSilicon HIP12

[Yicong Yang]

From: Yicong Yang <yangyicong at hisilicon.com>

Add support for Data Source packet on HIP12. Support counting L2 HITM for c2c
statistic since it was missing.

Change since v2:
- split the kernel/userspace changes into different patch
- revise some mem_snoop decoding according to the discussion
- count missing L2 HITM for c2c statistic
