[PATCH 0/7] arm64/kvm: common ESR_ELx definitions and decoding

Currently we have two sets of macros used for ESR_ELx handling, one used
by core arm64 code and the other used by KVM. These differ slightly in
naming convention and style of definition.

This patch series introduces and migrates all users to a common set of
macros for ESR_ELx handling, preventing further drift.

Additionally this series adds exception class decoding when reporting
exceptions, saving deveopers from having to perform tedious mental
arithmetic to figure out what the likely cause of an unexpected
exception was.

Thanks,
Mark.
