Subject: [PATCH] mips: fix cacheinfo
Date: Tue, 16 Jul 2019 10:36:56 +0300 [thread overview]
Message-ID: <20190716073656.24924-1-vladimir.kondratiev@linux.intel.com> (raw)
Because CONFIG_OF defined for MIPS, cacheinfo attempts to fill information
from DT, ignoring data filled by architecture routine. This leads to error
reported
cacheinfo: Unable to detect cache hierarchy for CPU 0
Way to fix this provided in
commit fac51482577d ("drivers: base: cacheinfo: fix x86 with
CONFIG_OF enabled")
Utilize same mechanism to report that cacheinfo set by architecture
specific function
