Vasily Gorbik 4ac24c092b s390: fix register clobbering in CALL_ON_STACK ... CALL_ON_STACK defines and initializes register variables. Inline assembly which follows might trigger compiler to generate memory access for "stack" argument (e.g. in case of S390_lowcore.nodat_stack). This memory access produces a function call under kasan with outline instrumentation which clobbers registers. Switch "stack" argument in CALL_ON_STACK helper to use memory reference constraint and perform load instead.
