Doesn't build:

Must be due to recent binutils upgrade, because 2.6.37 doesn't build
anymore either.

Looks like these patches are needed:

There was a long discussion caused by a breakage in linux-next with a
2.21-snapshot release of binutils in Debian/sid:
"Re: linux-next: Tree for March 8 (BROKEN: arch/x86/kernel/entry_32.S?
Debian's binutils/as?)"

The result were two patches [1] and [2] which helped to build a
linux-next kernel with new binutils.
[1] affects also 2.6.38, [2] is for linux-next (upcoming 2.6.39).
Ingo combined both fixes as one [3] and accepted it to
tip:x86/trampoline (see [4]).
This single fix found already its way to linux-next tree (where I am on).
