Russell King	02fcb97436	[ARM] Remove the __arch_* layer from uaccess.h ... Back in the days when we had armo (26-bit) and armv (32-bit) combined, we had an additional layer to the uaccess macros to ensure correct typing. Since we no longer have 26-bit in this tree, we no longer need this layer, so eliminate it. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>	2006-06-28 17:53:27 +01:00
Nicolas Pitre	fadab0943d	[ARM] 2948/1: new preemption safe copy_{to|from}_user implementation ... Patch from Nicolas Pitre This patch provides a preemption safe implementation of copy_to_user and copy_from_user based on the copy template also used for memcpy. It is enabled unconditionally when CONFIG_PREEMPT=y. Otherwise if the configured architecture is not ARMv3 then it is enabled as well as it gives better performances at least on StrongARM and XScale cores. If ARMv3 is not too affected or if it doesn't matter too much then uaccess.S could be removed altogether.
