Messages in this thread Patch in this message | | | From | Tejun Heo <> | Subject | [PATCH 03/10] CRIS: Change DEFINE_PER_CPU of current_pgd to be non volatile. | Date | Wed, 24 Jun 2009 15:45:17 +0900 |
| |
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.
tj: extern DEFINE_PER_CPU() replaced with DECLARE_PER_CPU()
[ Impact: code cleanup ]
