[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. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
