Heiko Carstens 7f8073cfb0 s390/ptrace: Fix pointer dereferencing in regs_get_kernel_stack_nth() ... The recent change which added READ_ONCE_NOCHECK() to read the nth entry from the kernel stack incorrectly dropped dereferencing of the stack pointer in order to read the requested entry. In result the address of the entry is returned instead of its content. Dereference the pointer again to fix this.
