ARM: 8047/1: 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 ARM CPUs. Signed-off-by: Will Deacon <will.deacon@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
