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@...ux-foundation.org>

    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.

is what you were looking for.  If not, very sorry for interrupting you.

Thanks,
