It is possible for all CPUs to miss the pending cpumask becoming clear,
and then nobody resetting it, which will cause the lockup detector to
stop working. It will eventually expire, but watchdog_smp_panic will
avoid doing anything if the pending mask is clear and it will never be
reset.

I didn't yet test this ps3vram related change, but based
on the ps3disk testing I think this change will
Until now, all tests involving CONFIG_STRICT_KERNEL_RWX were done with
DEBUG_RODATA_TEST to check the result. But now that
CONFIG_STRICT_KERNEL_RWX is selected by default, it came without
CONFIG_DEBUG_RODATA_TEST and led to the following Oops
