Hi,

I tried to compile the patched llvmlinux kernel with the latest clang but it
fails with:


  AS      arch/x86/realmode/rm/trampoline_64.o
invalid fixup kind!
UNREACHABLE executed at X86ELFObjectWriter.cpp:166!
#0 0x46509fe llvm::sys::PrintStackTrace(llvm::raw_ostream&)
/data/llvm/lib/Support/Unix/Signals.inc:425:42
...


kernel config: x86_64_defconfig
kernel tree llvmlinux v3.19-rc4-183-g230b22d72454
clang version 3.7.0 (trunk 232275) (llvm/trunk 215340:232281M
