From cdaabbd74b15296acf09215355a7f3b07b92b83e Mon Sep 17 00:00:00 2001 From: Russell King Date: Sun, 12 Mar 2006 22:36:06 +0000 Subject: [ARM] iwmmxt thread state alignment This patch removes the reliance of iwmmxt on hand coded alignments. Since thread_info is always 8K aligned, specifying that fpstate is 8-byte aligned achieves the same effect without needing to resort to hand coded alignments.
