Subject: [PATCH v5 0/3] LLVM/Clang fixes for a few defconfigs

Hi all,

This series includes a set of fixes for LLVM/Clang when building
a few defconfigs (powernv, ppc44x, and pseries are the ones that our
CI configuration tests [1]). The first patch fixes pseries_defconfig,
which has never worked in mainline. The second and third patches fixes
issues with all of these configs due to internal changes to LLVM, which
point out issues with the kernel.

These have been broken since July/August, it would be nice to get these
reviewed and applied. Please let me know what I can do to get these
applied soon so we can stop applying them out of tree.
