Merge tag 's390-5.16-5' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 fixes from Heiko Carstens:

 - Add missing handling of R_390_PLT32DBL relocation type in
   arch_kexec_apply_relocations_add(). Clang and the upcoming gcc 11.3
   generate such relocation entries, which our relocation code silently
   ignores, and which finally will result in an endless loop within the
   purgatory code in case of kexec.

 - Add proper handling of errors and print error messages when applying
   relocations

 - Fix duplicate tracking of irq nesting level in entry code

 - Let recordmcount.pl also look for jgnop mnemonic. Starting with
   binutils 2.37 objdump emits a jgnop mnemonic instead of brcl, which
   breaks mcount location detection. This is only a problem if used with
   compilers older than gcc 9, since with gcc 9 and newer compilers
   recordmcount.pl is not used anymore.

 - Remove preempt_disable()/preempt_enable() pair in
   kprobe_ftrace_handler() which was done for all architectures except
   for s390.

 - Update defconfig
