Heiko Carstens 1856405862 s390/test_unwind: fix CALL_ON_STACK tests ... [ Upstream commit f22b9c219a798e1bf11110a3d2733d883e6da059 ] The CALL_ON_STACK tests use the no_dat stack to switch to a different stack for unwinding tests. If an interrupt or machine check happens while using that stack, and previously being on the async stack, the interrupt / machine check entry code (SWITCH_ASYNC) will assume that the previous context did not use the async stack and happily use the async stack again. This will lead to stack corruption of the previous context. To solve this disable both interrupts and machine checks before switching to the no_dat stack.
