Subject: [PATCH 3/9] CRIS: Change DEFINE_PER_CPU of current_pgd to be non volatile.
From: Jesper Nilsson <jesper.nilsson@...s.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 ]
