i've put the commits (and a good number of dependent commits) into the
new tip/x86/xen-64bit topic branch.

It quickly broke the build in testing:

include/asm/pgalloc.h: In function ‘paravirt_pgd_free':
include/asm/pgalloc.h:14: error: parameter name omitted
arch/x86/kernel/entry_64.S: In file included from
arch/x86/kernel/traps_64.c:51:include/asm/pgalloc.h: In function ‘paravirt_pgd_free':
include/asm/pgalloc.h:14: error: parameter name omitted
[...]

with this config:

http://redhat.com/~mingo/misc/config-Wed_Jun_25_16_37_51_CEST_2008.bad

this could easily be some integration mistake on my part, so please
double-check the end result.

Merging it into tip/master is a bit tricky, due to various interactions.
This should work fine if you check out the latest tip/master:

git-merge tip/x86/xen-64bit
[ ... fix up the trivial merge conflict ... ]

i've already merged tip/x86/xen-64bit-base topic into master, to make it
easier. (there were a few preconditions for the 64-bit Xen patches which
arent carried in linux-next - such as the nmi-safe changes.)
