Subject: [PATCH AUTOSEL 4.14 04/44] mips: fix cacheinfo
Date: Tue, 13 Aug 2019 22:17:53 -0400	[thread overview]
Message-ID: <20190814021834.16662-4-sashal@kernel.org> (raw)
In-Reply-To: <20190814021834.16662-1-sashal@kernel.org>

From: Vladimir Kondratiev <vladimir.kondratiev@linux.intel.com>

[ Upstream commit b8bea8a5e5d942e62203416ab41edecaed4fda02 ]

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
