locking: Fix rwlock support in <linux/spinlock_up.h>
Architecture support for rwlocks must be available whether or not
CONFIG_DEBUG_SPINLOCK has been defined. Move the definitions of the
arch_{read,write}_{lock,trylock,unlock}() macros such that these become
visbile if CONFIG_DEBUG_SPINLOCK=n.
This patch prepares for converting do_raw_{read,write}_trylock() into
inline functions. Without this patch that conversion triggers a build
failure for UP architectures, e.g. arm-ep93xx. I used the following
kernel configuration to build the kernel for that architecture:
CONFIG_ARCH_MULTIPLATFORM=y
CONFIG_ARCH_MULTI_V7=n
CONFIG_ATAGS=y
CONFIG_MMU=y
CONFIG_ARCH_MULTI_V4T=y
CONFIG_CPU_LITTLE_ENDIAN=y
CONFIG_ARCH_EP93XX=y
