[PATCH] ppc32: oops on kernel altivec assist exceptions
If we should happen to get an altivec assist exception while executing in
the kernel, we will currently try to handle it and fail, and end up oopsing
with (apparently) a segfault. (An altivec assist exception occurs for
floating-point altivec instructions with denormalized inputs or outputs if
the altivec unit is in java mode.)
This patch checks explicitly if we are in user mode and prints a useful
message if not.
