Okay. But just in case. I had to learn about git and do a checkout.
git log v4.1-rc8 arch/x86/kvm/mmu.c shows:
commit 5ec45a192fe6e287f0fc06d5ca4f3bd446d94803 Author: Andrew Morton <akpm@linux-foundation.org> Date: Wed Jun 10 11:15:02 2015 -0700
arch/x86/kvm/mmu.c: work around gcc-4.4.4 bug
Fix this compile issue with gcc-4.4.4:
arch/x86/kvm/mmu.c: In function 'kvm_mmu_pte_write': arch/x86/kvm/mmu.c:4256: error: unknown field 'cr0_wp' specified in initializer arch/x86/kvm/mmu.c:4257: error: unknown field 'cr4_pae' specified in initializer arch/x86/kvm/mmu.c:4257: warning: excess elements in union initializer ...
gcc-4.4.4 (at least) has issues when using anonymous unions in initializers.

Hopefully commit 5ec45a192fe6e287f0fc06d5ca4f3bd446d94803 is what you were looking for. If not, very sorry for interrupting you.
Thanks, Don
