hm, actually - the order is correct so no need to rebase any of this.

We've got two topics: tip/x86/apic and tip/x86/x2apic.

both tip/x86/x2apic and tip/x86/apic were OK standalone. I merged them 
together in this commit:

commit 453c1404c5273a30d715e5a83372a78cff70b6d9
Merge: a208f37... 35b6805...

    Merge branch 'x86/apic' into x86/x2apic

    Conflicts:

        arch/x86/kernel/paravirt.c
        arch/x86/kernel/smpboot.c
        arch/x86/kernel/vmi_32.c
        arch/x86/lguest/boot.c
        arch/x86/xen/enlighten.c
        include/asm-x86/apic.h
        include/asm-x86/paravirt.h

    Signed-off-by: Ingo Molnar <mingo@...e.hu>

and that didnt work straight away, so i applied your fixups - but that's 
the next commit. So there's only a single commit that is not bisectable 
and that's OK.

so unless there's some other breakage i missed, this should be fine and 
no need to resend/rebase anything.
