[PATCH 0/5] CM error report fixes

From: Paul Burton
Date: Tue Sep 22 2015 - 13:27:11 EST


This series fixes a few problems with support for the CM, in particular
relating to CM3 which has a 64 bit interface to the core. These issues
prevented reporting of CM errors (useful debug output when tracking the
source of a bus error) in some situations, and could cause further
exceptions.

Paul Burton (5):
MIPS: clarify mips_cm_is64 documentation
MIPS: don't read GCRs when a CM is not present
MIPS: avoid buffer overrun in mips_cm_error_report
MIPS: allow read64 GCR accessors to work on MIPS32 kernels
MIPS: always read full 64 bit CM error GCRs for CM3
