Will Deacon da7196e1f9 perf, ARM: Modify kuser rmb() call to compile for Thumb-2 ... The Thumb-2 instruction set does not provide an encoding for sub pc, r0, #95 as present in the rmb() definition used by perf. This results in compilation failure when using a compiler targetting an instruction set other than ARM. This patch redefines rmb() for ARM by casting the address of the kuser helper to a function pointer, therefore getting the compiler to take care of making the call. Patch taken against tip/master.
