Subject: Blackfin: push access_ok() L1 attribute down
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=a43b739f257fd2569e11c6c93fbb86df382848e9;p=deliverable%2Flinux.git

Blackfin: push access_ok() L1 attribute down

There is no need for the L1 attribute to be on the prototype of the
access_ok() function as all consumers of the function do not care where it
lives -- they'll always use pcrel calls to get to it.  This prevents
pointless recompiles of most of the system when this config option changes.
