Here you can find what's needed to compile the skas patch. This applies and compiles cleanly
against 2.6.2-v1 (see instructions there for applying that).

00-2.6.2-v1-host-SKAS.patch.bz2 contains all the patches here.

Changes from last skas patch (i.e. the one in -v8):

- now, C-06-Remove-old-skas-support.patch (which replaces C-01-Compile_no_proc_mm.patch) removes
  all the SKAS code from the kernel (the only remaining one is the code for ptrace, inside UML's
  arch tree). This patch is meant for inclusion in mainline.
- F-01 is unchanged; instead, I put inside E-01 the changes to the prototype of do_mmap2
  (which come from the stock Uml patch).
- E-02 has been dropped at author request, since it was buggy.

E-Skas					These patches makes UML support the SKAS mode for
					nested UML. The two patches are in order.

F-i386					This patch, which requires the E-Skas one, makes
					the host kernel able to support the SKAS mode for
					guests.


---C-MainChanges

C-06-Remove-old-skas-support.patch

---E-Skas

E-01-Add_proc_mm_support.patch		Adds /proc/mm support to UML to run nested UML's (actually
					from Jeff Dike, only some bits changed). This is needed also
					to apply the host-skas patch (i.e. F-01). See also E-02.

E-02-Proc_mm_speedup.patch		This is a speedup from Ingo Molnar on the host kernel side.
					Just apply this if you applied E-01. It is the MM_COPY_SEGMENTS
					removal (it becomes a no-op). Applied the ret = count fix.
---F-i386

F-01-i386_skas_support.patch		This adds the support for SKAS mode to the host kernel.

CREDITS

This code comes from these people:
- Ingo Molnar; he ported to 2.6 the skas patch, and his port is what I use.
- the UML-devel mailing list for testing and help
- and finally me (Paolo Giarrusso, alias Blaisorblade blaisorblade_spam (at) yahoo (dot) it).

However, blame me for every bug you find, and thanks them for their work.
