Merge tag 'sh-for-v6.4-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/glaubitz/sh-linux

Pull sh updates from John Paul Adrian Glaubitz:
 "This is a bit larger than my previous one and mainly consists of
  clean-up work in the arch/sh directory by Geert Uytterhoeven and Randy
  Dunlap.

  Additionally, this fixes a bug in the Storage Queue code that was
  discovered while I was reviewing a patch to switch the code to the
  bitmap API by Christophe Jaillet.

  So this contains both a fix for the original bug in the Storage Queue
  code that can be backported later as well as the Christophe's patch to
  swich the code to the bitmap API.

  Summary:

   - Use generic GCC library routines

   - sq: Use the bitmap API when applicable

   - sq: Fix incorrect element size for allocating bitmap buffer

   - pci: Remove unused variable in SH-7786 PCI Express code

   - mcount.S: fix build error when PRINTK is not enabled

   - remove sh5/sh64 last fragments

   - math-emu: fix macro redefined warning

   - init: use OF_EARLY_FLATTREE for early init

   - nmi_debug: fix return value of __setup handler

   - SH2007: drop the bad URL info"
