arm: Remove bogus comment in futex_atomic_cmpxchg_inatomic()
commit 522d7dec(futex: Remove redundant pagefault_disable in
futex_atomic_cmpxchg_inatomic()) added a bogus comment.
/* Note that preemption is disabled by futex_atomic_cmpxchg_inatomic
* call sites. */
Bogus in two aspects:
1) pagefault_disable != preempt_disable even if the mechanism we use
is the same
2) we have a call site which deliberately does not disable pagefaults
as it wants the possible fault to be handled - though that has been
changed for consistency reasons now.
Sigh. I really should have seen that when committing the above. :(
