[PATCH 0/4] powerpc/64: ELFv2 conversion

[Nicholas Piggin]

This series has the steps to remove ELFv1 from the kernel build.
Patch 1 is a build fix, 2 defaults everything to ELFv2, 3 is
really a separate issue that concerns userspace. 4 removes v1
support.

Would like to try getting patch 1 in as a fix, then 2,3 merged in
the next merge window.

Thanks,
Nick

Nicholas Piggin (4):
  powerpc/64: Force ELFv2 when building with LLVM linker
  powerpc/64: Make ELFv2 the default for big-endian builds
  powerpc/64s: Remove support for ELFv1 little endian userspace
  powerpc/64: Remove support for kernel's built with ELFv1 ABI
