commit 0b0747d upstream. The following processes run into a deadlock. CPU 41 was waiting for CPU 29 to handle a CSD request while holding spinlock "crashdump_lock", but CPU 29 was hung by that spinlock with IRQs disabled.

Consequently it's not required to disable IRQs. Replace the spinlock with a mutex to fix the deadlock.
