Subject: MIPS: DEC: Rate-limit memory errors for KN01 systems
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=798715fa06e1b3ff0f672721cca0a6789d5ebd37;p=thirdparty%2Fkernel%2Flinux.git

MIPS: DEC: Rate-limit memory errors for KN01 systems

Similarly to memory errors in ECC systems also rate-limit memory parity
errors for KN01 DECstation and DECsystem models.  Unlike with ECC these
events are always fatal and are less likely to cause a message flood,
but handle them the same way for consistency.
