AFAICS LLVMLinux is still a work-in-progress project.
Three patches are labeled with "DO-NOT-UPSTREAM"...
DO-NOT-UPSTREAM scsi, osd, LLVMLinux: Remove __weak attribute
WORKAROUND DO-NOT-UPSTREAM x86, boot: Work around clang PR18415.
DO-NOT-UPSTREAM xen, LLVMLinux: Remove VLAIS from xen mmu
I cannot say much to the other patches - what status they have -
"reported to BTS and have no feedback" or "still discussed" or
whatever.
Some bug-reports are very old - especially in the LLLVM and CLANG BTS.
Can you be concrete on the patches which have in your eyes "a few
objectionable hacks in"?

Linux kernel development <-> LLVMLinux development <-> LLVM/CLANG development
BTW, LLVMLinux is a project hosted at Linux Foundation.
I also remember the interview with Linus and c't magazine (German, I
bought this edition) where he talks about compiler and especially
using LLVM for compiling a Linux-kernel.
If you look at the git-logs, there are people found bugs using
LLVM/CLANG and fixed them.
Personally, I like the "verbose" output of LLVM/CLANG more than GCC v4.9.
I did not try any GCC v5.x.
Thanks.
