Hi guys,
thanks for your further input.

Following through Ben's mail below and Konrad's later mail suggesting 
the same, I tried to get these patches in. I'd however require your help 
before I feel I can safely proceed.

Please see below:

After consultation with the manual I decided to give it a dry-run before 
and check with you guys first. First of all, I assume I'm righht that 
this is a patch to the *linux kernel* and not the xen-sources as I could 
not find the referenced files in the xen tree.

> patch -p1 -R < c79c498.patch
vm-host # patch --dry-run -p1 -R < c79c498.patch
patching file arch/x86/xen/enlighten.c
Hunk #2 succeeded at 1431 (offset 14 lines).

I am slightly worried about the last message, not so much about the 
offset, but rather only the "Hunk #2" success. Why is there no "Hunk #1" 
when there's a "Hunk #2"?

patching file arch/x86/xen/enlighten.c
Hunk #1 succeeded at 1367 (offset 226 lines).
patching file arch/x86/xen/mmu.c
Hunk #1 succeeded at 434 (offset 19 lines).
Hunk #2 succeeded at 482 (offset 19 lines).
Hunk #3 succeeded at 495 (offset 19 lines).

That seems to be o.k. from my understanding?

For this patch I copied the complete text from the https address above 
and copied it to a file named 229.patch. Then I issued the following 
command:
vm-host # patch --dry-run -p1 -R < 229.patch
patching file arch/x86/include/asm/pgtable.h
Unreversed patch detected!  Ignore -R? [n]

I am not sure what to make out of this? Could you please provide some input.

Thanks and sorry for those probably dumb questions. I'm new to this 
(automated) patching thing, and with a little help, the first time 
usually works out well.
