H A D | spinlock.h | 5686b06c Wed Oct 09 09:54:27 CDT 2013 Will Deacon <will.deacon@arm.com> arm64: lockref: add support for lockless lockrefs using cmpxchg
Our spinlocks are only 32-bit (2x16-bit tickets) and our cmpxchg can deal with 8-bytes (as one would hope!).
This patch wires up the cmpxchg-based lockless lockref implementation for arm64.
