Ok... now that I (unintentionally) went overboard on this, why not just
document how it works and leave it as is?

[PATCH] Re: PAE
> We're taking quite a chunk out of lowmem, though....
Uhm, well, no, we don't. We should though, fix is below.
Current code in unstable takes the address space away from the
vmalloc area, not the lowmem area. vmalloc space is 128 MB by
default, so the non-PAE hypervisor hole fits in and it works
nevertheless. The larger PAE mode hypervisor hole doesn't fit
in, so it breaks when you use enougth memory (somewhere around
800-900 MB). I think that is the bug Scott Parish trapped into.

[PATCH] [PATCH] Increase size of sxpr parser input buffer

[PATCH] Mkbuildtree little fix
Hi, here is a really small fix for mkbuildtree.
With my 'find' version [1], I get many of these warning when using mkbuildtree:
find: warning: you have specified the -maxdepth option after a
non-option argument -type, but options are not positional (-maxdepth
affects tests specified before it as well as those specified after it).
Please specify options before other arguments.
My patch just correct the ordering of the options, it should be
harmless, but I didn't test with other versions of find.

[PATCH] [patch] pgtable.c cleanups
Hi guys,
The new mm_(un)pin stuff is certainly a nice optimization.
But can we take care a bit more about coding style issues
and write code not *that* hackish please? Casts, code
duplication, "unsigned long" for page table entries *again*.
And a few more variables also make the code more readable
(and gcc should be clever enougth that this isn't a
performance hit). We want to have that merged some day in
mainline, don't we?
The patch below cleans up the pin/unpin code in pgtable.c
I've created two helper functions to factor out common code,
the page table walk is basically the same for both pin and
unpin, it's just different page flags. Also fixed up the
walk code to correcly walk through all 4 levels linux has,
so it works correctly for the PAE case. For x86_64 it
should work fine as well (untested though).
please apply,
Gerd

[PATCH] [PATCH] tools/libxc/xc_vmx_build.c broken
xc_vmx_build pins the level 2 page table too early so that subsequent maps

To solve this, this patch pins the l2pt at the end of the function when
all memory initializations are finalized.
