parisc/unaligned: Fix emulate_ldw() breakage
The commit e8aa7b17fe41 broke the 32-bit load-word unalignment exception handler because it calculated the wrong amount of bits by which the value should be shifted. This patch fixes it. Signed-off-by: Helge Deller <deller@gmx.de> Fixes: e8aa7b17fe41 ("parisc/unaligned: Rewrite inline assembly of emulate_ldw()") Cc: stable@vger.kernel.org # v5.18
