	  This workaround defines cpu_relax() as smp_mb(), preventing correctly

	  written polling loops from denying visibility of updates to memory.

	bool "ARM errata: Possible cache data corruption with hit-under-miss enabled"

	depends on CPU_V6 && !SMP

	help

	  This options enables the workaround for the 364296 ARM1136

	  r0p2 erratum (possible cache data corruption with

	  hit-under-miss enabled). It sets the undocumented bit 31 in

	  the auxiliary control register and the FI bit in the control

	  register, thus disabling hit-under-miss without putting the

	  processor into full low interrupt latency mode. ARM11MPCore

	  is not affected.
