It was based on the tip master on the day I sent the v12 patch set, i.e.,
Monday night in the US west coast.

What does it complain?

I just did a rebase on the latest tip master, and did find a build bug
caused by:

[PATCH v12 33/37] x86/entry: Add fred_entry_from_kvm() for VMX to handle IRQ/NMI

as <asm/export.h> is deprecated by <linux/export.h> yesterday.

After I replaced it, it compiles and boots. What should I do now?

Thanks!
