Hi, Richard,

aarch64 has no vendor_id in /proc/cpuinfo, so detect_vendor() returns 0

L3_NONCONT_CAT spuriously fails on every ARM MPAM platform.
Define ARCH_ARM, short-circuite detect_vendor() to it on aarch64, and
add it to the AMD/Hygon alwasy-supports early-out in
arch_support_noncont_cat().
aarch64 has many implementers (ARM 0x41, NVIDIA 0x43, etc...) but MPAM
mandates non-contiguous CPBM uniformly, so per-implementer bits is not
needed here.

I see you have three patches for selftest. Seems they are together. But
they are not assembled in a series like [PATCH 1/3], [PATCH 2/3], [PATCH
3/3].
Could you please send them in a series?
Thanks.
