[uml-devel] More split-arch patches

[Bodo S. <bst...@fu...>]

Attached are the next 4 patches, that are needed for my s390 port.
I have done some short tests on i386 in 2.6.10-rc2-mm4 + incremental
patches and didn't see errors.

The last patch called "faultinfo-rework is quite invasive. Thus,
it needs further testing.
