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

    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 ]

    Updated such that extern DEFINE -> DECLARE change is done here not
    later in the series as suggested by Christoph Lameter.
