Apart from Powerpc build regressions we have noticed s390 build regression.
The S390 defconfig builds failed on Linux stable-rc 4.19.321-rc1 due to
following build warnings / errors with clang-18 and gcc-12.

This is a same problem on current stable-rc review on
   - 4.19.321-rc1 review

In the case of stable-rc linux-4.19.y

Reported-by: Linux Kernel Functional Testing <lkft@...aro.org>

Following two commits have been added on 4.19.321-rc1.
-------
  s390/cio: rename bitmap_size() -> idset_bitmap_size()
  commit c1023f5634b9bfcbfff0dc200245309e3cde9b54 upstream.

  bitmap: introduce generic optimized bitmap_size()
  commit a37fbe666c016fd89e4460d0ebfcea05baba46dc upstream.
