[uml-devel] 2.6.3 skas mode host and guest success

[uml-devel] 2.6.3 skas mode host and guest success

[Michael Clark]

Hi All,

After hunting through the list. I couldn't find a patch
that cleanly applies to 2.6.3 (on top of latest uml patch)
to re-enable skas host support.

So after merging parts of Paulo's and Ingo's skas patches
for 2.6.0 and 2.6.2, I now have a single patch that cleanly
applies and runs for me both as a host and guest with 2.6.3
rediffed against the latest uml patch.

First apply 2.6.3-rc2.1 uml patch (cleanly applies to 2.6.3)

   http://www.user-mode-linux.org/mirror/uml-patch-2.6.3-rc2-1.bz2

Then apply the skas patch:

   http://www.metaparadigm.com/~mclark/uml/uml-2.6.3-skas-1.patch

It includes the following changes:

   * PROC_MM Kconfig
   * add back skas ptrace support
   * export ldt functions with mm argument
   * export do_mmap2 with mm argument
   * compatibility wrapper for do_mmap_pgoff
   * proc_mm now uses __init_new_context

Use at your own risk - it boots and runs skas mode guest here ;)
