sparc32: vm_area_struct access for old Sun SPARCs.
Upstream commit 961246b4ed8da3bcf4ee1eb9147f341013553e3c 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. Signed-off-by: Olivier DANET <odanet@caramail.com> Signed-off-by: David S.
