Subject: [PATCH] MIPS: Use "R" constraint for cache_op.
X-Git-Tag: v2.6.16.12~5
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=97644aa31cb72ce0e9ebfae27042bc56db672dee;p=thirdparty%2Fkernel%2Fstable.git

[PATCH] MIPS: Use "R" constraint for cache_op.

Gcc might emit an absolute address for the the "m" constraint which
gas unfortunately does not permit.
