[patch] ~420 seconds in cpu_detect
playing with hdt on a soekris 4801,
Im getting HUGE delays in cpu_detect.
I added some timing code, heres what Im seeing
ACPI: Detecting
0 mS in detect_acpi
MEMORY: Detecting
0 mS in detect_memory
DMI: Detecting Table
DMI: ERROR ! Table not found !
DMI: Many hardware components will not be detected !
55 mS in detect_dmi

[PATCH 0/8] lguest
As promised to Andrew, and with much thanks to Andi Kleen for feedback,
this is the new series of lguest patches.
Main change is the move to drivers/lguest (for future non-i386
expansion), but lots of cleanups driven by Andi's feedback and the
documentation effort (which made me examine every line of code).
It's not perfect, but it's definitely useful.
Cheers,
Rusty.

[PATCH 00/10] REVIEW: Xen patches for 2.6.24
This is my current set of updates to Xen for 2.6.24. This is largely
a bugfix set, and a couple of them are also relevent to 2.6.23.
These are in the pre-x86 merge form; I'll update them once the merge
goes into git.
Quick overview:
- remove some dead code in arch/i386/mm/init.c
- clean up some duplicate includes
- when sending an IPI, yield the vcpu if the destination doesn't have

[patch 0/4] Clean up asm/bugs.h, identify_cpu() and update COMPAT_VDSO
Hi Andi,
Four patches:
- clean up asm/bugs.h, by moving all the C code into its own C file
- split identify_cpu() into boot and secondary variants, so that
boot-time setup functions can be marked __init
- repost of the COMPAT_VDSO patches with a bit more robustness from
unknown DT_tags, and functions marked __init, since all this is
boot-time only setup.
Thanks,
J

[PATCH 1/7] lguest: documentation pt I: Preparation
The netfilter code had very good documentation: the Netfilter Hacking
HOWTO. Noone ever read it.
So this time I'm trying something different, using a bit of
Knuthiness. Start with drivers/lguest/README.

[PATCH 00/10] paravirt/subarchitecture boot protocol
This series updates the boot protocol to 2.07 and uses it to implement
paravirtual booting. This allows the bootloader to tell the kernel
what kind of hardware/pseudo-hardware environment it's coming up under,
and the kernel can use the appropriate boot sequence code.
Specifically:
- Update the boot protocol to 2.07, which adds fields to specify the
