The following S390 build failed on stable-rc 5.10.y with gcc-12 and clang due
to following warnings and errors [1].

s390:
  build:
    * gcc-8-defconfig-fe40093d
    * gcc-12-defconfig
    * clang-18-defconfig


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

The bisect points to 0fbb54ce4bff ("KVM: s390: pv: avoid stalls when
making pages secure")
as the problematic commit [ Upstream commit
f0a1a0615a6ff6d38af2c65a522698fb4bb85df6 ].
