Liam Howlett 58ee5a0de1 m68k: Add missing mmap_read_lock() to sys_cacheflush() ... [ 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: cd2567b685 ("m68k: call find_vma with the mmap_sem held in sys_cacheflush()") Signed-off-by: Liam R.
