Because the Microblaze syscall macros don't include r11 in the clobber
list. I suppose an alternative solution would just change the userspace
macros and not the kernel, even though there is a bug in the kernel.
Michal, is the Microblaze ABI considered "locked down" now, or is a
kernel solution still permitted?
