[PATCH 3/9] CRIS: Change DEFINE_PER_CPU of current_pgd to be non volatile.

[Tejun Heo <tj@kernel.org>]

From: Jesper Nilsson <jesper.nilsson@axis.com>

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.

[ Impact: code cleanup ]
