From aac72277fda6ef788bb8d5deaa502ce9b9b6e472 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Wed, 26 Jan 2011 20:06:06 +0000 Subject: rwsem: Move duplicate function prototypes to linux/rwsem.h All architecture specific rwsem headers carry the same function prototypes. Just x86 adds asmregparm, which is an empty define on all other architectures. S390 has a stale rwsem_downgrade_write() prototype. Remove the duplicates and add the prototypes to linux/rwsem.h Signed-off-by: Thomas Gleixner Cc: Peter Zijlstra Cc: David Howells Cc: Benjamin Herrenschmidt Cc: Richard Henderson Acked-by: Tony Luck Acked-by: Heiko Carstens Cc: Paul Mundt Acked-by: David Miller Cc: Chris Zankel LKML-Reference: <20110126195833.970840140@linutronix.de> Signed-off-by: Thomas Gleixner --- arch/x86/include/asm/rwsem.h | 9 --------- 1 file changed, 9 deletions(-) (limited to 'arch/x86/include/asm/rwsem.h') diff --git a/arch/x86/include/asm/rwsem.h b/arch/x86/include/asm/rwsem.h index 776d76fe2f90..df4cd32b4cc6 100644 --- a/arch/x86/include/asm/rwsem.h +++ b/arch/x86/include/asm/rwsem.h @@ -39,15 +39,6 @@ #ifdef __KERNEL__ #include -extern asmregparm struct rw_semaphore * - rwsem_down_read_failed(struct rw_semaphore *sem); -extern asmregparm struct rw_semaphore * - rwsem_down_write_failed(struct rw_semaphore *sem); -extern asmregparm struct rw_semaphore * - rwsem_wake(struct rw_semaphore *); -extern asmregparm struct rw_semaphore * - rwsem_downgrade_wake(struct rw_semaphore *sem); - /* * The bias values and the counter type limits the number of * potential readers/writers to 32767 for 32 bits and 2147483647 -- cgit v1.2.3
