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.

/* 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.
