Subject: [PATCH] powerpc/mce: Modify the real address error logging messages
References: jsc#SLE-18194
Patch-mainline: v5.18-rc1
Git-commit: 0a182611d149b5b747014fbb230ec35b20a45c86
To avoid ambiguity, modify the strings in real address error
logging messages to "foreign/control memory" from "foreign",
Since the error discriptions in P9 user manual and P10 user
manual are different for same type of errors.
P9 User Manual for MCE:
DSISR:59 Host real address to foreign space during translation.
DSISR:60 Host real address to foreign space on a load or store
access.
P10 User Manual for MCE:
DSISR:59 D-side tablewalk used a host real address in the
control memory address range.
DSISR:60 D-side operand access to control memory address space.
