From 376e210b71d7736775f43f32c5c7712f90aaf59a Mon Sep 17 00:00:00 2001 From: Kyle McMartin Date: Wed, 30 May 2007 02:27:46 -0400 Subject: [PATCH] [PARISC] fix "reduce size of task_struct on 64-bit machines" fallout Amazingly, parisc was the only arch effected by this... Convert register-sized loads/stores to always be 32-bit for these fields.
