MIPS: export __cmpxchg_small()
commit 90a88784cdb7757feb8dd520255e6cb861f30943 upstream.
Export the symbol __cmpxchg_small() for btrfs.ko that uses it to store
blk_status_t, which is u8. Reported by LKP:
>> ERROR: modpost: "__cmpxchg_small" [fs/btrfs/btrfs.ko] undefined!
Patch using the cmpxchg() https://lore.kernel.org/linux-btrfs/1d4f72f7fee285b2ddf4bf62b0ac0fd89def5417.1728575379.git.naohiro.aota@wdc.com/
