| H A D | Kbuild | c209f799 Fri Mar 14 12:47:05 CDT 2014 Will Deacon <will.deacon@arm.com> arm64: rwsem: use asm-generic rwsem implementation
asm-generic offers an atomic-add based rwsem implementation, which
can avoid the need for heavier, spinlock-based synchronisation on the
fast path.
This patch makes use of the optimised implementation for arm64 CPUs.
