[ Upstream commit f829b4b212a315b912cb23fd10aaf30534bb5ce9 ]
When the superuser flushes the entire cache, the mmap_read_lock() is not
taken, but mmap_read_unlock() is called. Add the missing
mmap_read_lock() call.
Fixes: cd2567b6850b1648 ("m68k: call find_vma with the mmap_sem held in sys_cacheflush()")
