ARM: 6655/1: Correct WFE() in asm/spinlock.h for Thumb-2 The content for ALT_SMP() in the definition of WFE() expands to 6 bytes (IT cc ; WFEcc.W), which breaks the assumptions of the fixup code, leading to lockups when the affected code gets run. This patch works around the problem by explicitly using an IT + WFEcc.N pair.
