[PATCH 0/2] arm64: Taint the kernel on different GMID_EL1.BS

[Catalin Marinas]

Hi,

The GMID_EL1.BS field determines the number of tags accessed by
STGM/LDGM. While I haven't heard of a system where this field differs
across CPUs in a system, it's better to check.

In addition, "upgrade" the sysreg storage in struct cpuinfo_arm64 to
u64.

Catalin Marinas (2):
  arm64: Change the cpuinfo_arm64 member type for some sysregs to u64
  arm64: Check if GMID_EL1.BS is the same on all CPUs
