[parisc-linux] misaligned handler failing...

[Grant Grundler]

grundler@debian:~$ /usr/X11R6/bin/xlock -mode morph3d
Access control list restored.
xlock: caught signal 10 while running morph3d mode (uid 1000).

I haven't explicitly tested all modes, but this is the only
failure I've seen.

grundler@debian:~$ fgrep 10 /usr/include/asm/signal.h
#define SIGBUS          10
#define SA_SIGINFO      0x00000010
#define _SA_SIGGFAULT   0x00000100 /* HPUX */
grundler@debian:~$

SIGBUS implies a misaligned address access....and dmesg output confirms
that theory:

xlock(16254): unaligned access to 0x4071402c at ip=0x400ea63f
Not-handled unaligned insn 0x2fe81205
Unaligned handler failed, ret = -1
xlock (pid 16254): Unaligned data reference (code 28)
