The DEFINE_PER_CPU of current_pgd was on CRIS defined using volatile, which is not needed. Remove volatile. Tested on an ARTPEC-3 (CRISv32) board. tj: extern DEFINE_PER_CPU() replaced with DECLARE_PER_CPU() [ Impact: code cleanup ] Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com> Signed-off-by: Tejun Heo <tj@kernel.org>
