[PATCH 19/32] kmsan: Accept ranges starting with 0 on s390

2023-11-15 Thread Ilya Leoshkevich
On s390 the virtual address 0 is valid (current CPU's lowcore is mapped there), therefore KMSAN should not complain about it. Disable the respective check on s390. There doesn't seem to be a Kconfig option to describe this situation, so explicitly check for s390. Signed-off-by: Ilya Leoshkevich
