[PATCH] uml: avoid malloc to sleep in atomic sections
Ugly trick to help make malloc not sleeping - we can't do anything else. But
this is not yet optimal, since spinlock don't trigger in_atomic() when
preemption is disabled.
Also, even if ugly, this was already used in one place, and was even more
bogus. Fix it.
