Revert "s390/smp: rework absolute lowcore access" This reverts commit 7d06fed77b7d8fc9f6cc41b4e3f2823d32532ad8. This introduced vmem_mutex locking from vmem_map_4k_page() function called from smp_reinit_ipl_cpu() with interrupts disabled. While it is a pre-SMP early initcall no other CPUs running in parallel nor other code taking vmem_mutex on this boot stage - it still needs to be fixed.
