[PATCH v3 0/4] arm_mpam: Add support for the MPAM v0.1 architecture version

[James Morse]

This is a v3 of Zeng's series to add support for MPAM v0.1.
Included are the changes Ben and I suggested, and a couple of bugs found while
testing it.

I've put the bug fixes first as you can hit these with mainline.
The patches for v0.1 enable MPAM on those platforms as this extra ID register
was missed.

Based on v7.1-rc2, and can be retrieved from 
https://git.kernel.org/pub/scm/linux/kernel/git/morse/linux.git mpam/arch_v0.1/v3


Thanks,

James
