Subject: [ 10/45] sparc32: vm_area_struct access for old Sun SPARCs.
Date: Fri, 26 Jul 2013 13:57:30 -0700	[thread overview]
Message-ID: <20130726205656.038293344@linuxfoundation.org> (raw)
In-Reply-To: <20130726205654.896050165@linuxfoundation.org>

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Olivier DANET <odanet@caramail.com>

Commit e4c6bfd2d79d063017ab19a18915f0bc759f32d9 ("mm: rearrange
vm_area_struct for fewer cache misses") changed the layout of the
vm_area_struct structure, it broke several SPARC32 assembly routines
which used numerical constants for accessing the vm_mm field.

This patch defines the VMA_VM_MM constant to replace the immediate values.
