internally.
The functions wireToRawEvent() and copyRawEvent() get memories first,
then allocate memory blocks sequentially for several objects include
'double' from there.
On m88k, the memory area for 'double' should be 8-byte aligned, but
sizeof(XIRawEvent) is 60 and sizeof(out->valuators.mask_len) is 8.
In this case, allocated 'double' memory was not 8-byte aligned.
Because of this, 'xeyes' on luna88k was aborted with Bus Error right
after moving mouse for several years with sys/arch/m88k/m88k/trap.c
r.127.
Tested by me on luna88k, ok matthieu@
