[uml-devel] [patch] host-skas support for 2.6.0, other UML fixes

[Ingo M. <mi...@el...>]

Jeff,

i've ported host-skas support to the 2.6.0 kernel. (patch attached.) The
patching order is:

  - create the 2.6.0 tree,
  - apply user-mode-linux.org/mirror/uml-patch-2.6.0-test9-1.bz2,
  - apply the attached uml-host-skas-2.6.0-A0 patch

other changes:

  - cleaned up the LDT changes (pass around mm not task)
  - fixed LDT flush bug (similar to the 2.4.23 one)

as an additional speedup, on 2.6.0 it's not necessary to copy the segments
(LDTs) explicitly anymore, so the MM_COPY_SEGMENTS call is not needed.
I've removed the code from UM architecture too, but kept a 0 return value
for /proc/mm, so that older UML binaries keep working.

i've tested the resulting host kernel and UML kernel as well, works as
expected. (Ran some LDT testcode too - that works fine as well.)
