2014-02-25	ARM: 7989/1: Delete asm/system.h	David Howells	1	-1/+0
	Delete ARM's asm/system.h. It's the last holdout and should be got rid of. This builds for defconfig, lpc32xx_defconfig, exynos_defconfig + XEN, the previous changed to a Gemini system and an omap3 config with TI_DAVINCI_EMAC.

2012-08-08	xen/arm: sync_bitops	Stefano Stabellini	1	-0/+27
	sync_bitops functions are equivalent to the SMP implementation of the original functions, independently from CONFIG_SMP being defined. We need them because _set_bit etc are not SMP safe if !CONFIG_SMP. But under Xen you might be communicating with a completely external entity who might be on another CPU (e.g. two uniprocessor guests communicating via event channels and grant tables). So we need a variant of the bit ops which are SMP safe even on a UP kernel.
