[PATCH 3/5] MIPS: avoid buffer overrun in mips_cm_error_report

Commit 3885c2b463f6 ("MIPS: CM: Add support for reporting CM cache errors") added cases for decoding errors reported by CM3, but leaves the buf variable which is printed as a string uninitialised for cause values other than 1, 2 or 3. Fix by ensuring the buf variable is initialised to an empty stri

[PATCH 1/5] MIPS: clarify mips_cm_is64 documentation

The documentation for mips_cm_is64 implied that the width of the CM GCRs would change depending upon the CPU, which is not true. Reword the explanation to be clearer that the GCR width is purely dependent upon the version of the CM. Signed-off-by: Paul Burton --- arch/mips/include/asm/mips-cm.h

This is incorrect & will lead to further exceptions. Fix by moving the GCR reads to after the check for whether a
