Ugh.
This actually causes a new warning for me:
arch/x86/kvm/emulate.o: warning: objtool: __ex_table+0x4: don't know how to handle reloc symbol type: kvm_fastop_exception
on an x86-64 allmodconfig build (and my normal clang build for my actual default config too).
Looking at the kvm code, that kvm_fastop_exception thing is some funky sh*t.
I _think_ the problem is that 'kvm_fastop_exception' is done with bare asm at the top-level and that triggers some odd interaction with other section data, but I really don't know.
Anyway, that thing is in my public tree now, because it's better to get it out and fixed and have the kvm people look at it.
