[PATCH] [PATCH] libxc: mmap doesn't return NULL on error...
Hi, was reading libxc code, and noticed this. Patch is bigger than
strictly necessary due to indent adjust.

[PATCH] [PATCH] Increase size of sxpr parser input buffer
Increase the size of the sxpr parser input buffer from 1024 characters, which
isn't long enough to hold larger domain configurations (xfrd transmits the
entire domain config sxpr as a single atom inside of another sxpr).

[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] IO-APIC in drivers/pci/quirks.c
This patch moves the IO-APIC include inside #ifdef CONFIG_X86_IO_APIC , which

[PATCH] stream fixes for migration
I've attached a patch for libxutil/libxc. This fixes one of the hangs =
I've seen during migrations. It applies against 2.0 and 2.0-testing.
Changes:
* Encountering EOF or error when xfrd reads from stream could cause an =
infinite loop.
* Cleaned up the closing of streams.
* Fixed several memory leaks.

[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.
