[PATCH 3/3] Gdt page isolation
Make GDT page aligned and page padded to support running inside of a
hypervisor. This prevents false sharing of the GDT page with other
hot data, which is not allowed in Xen, and causes performance problems
in VMware.
Rather than go back to the old method of statically allocating the
GDT (which wastes unneded space for non-present CPUs), the GDT for
APs is allocated dynamically.

[PATCH 0/7] Using %gs for per-cpu areas on x86
OK, here it is. Benchmarks still coming. This is against Andi's
2.6.18-rc7-git3 tree, and replaces the patches between (and not
including) i386-pda-asm-offsets and i386-early-fault.
One patch is identical, one is mildly modified, the rest are
re-implemented but inspired by Jeremy's PDA work.
Thanks,
Rusty.

Per-cpu patches on top of PDA stuff...
Hi Jeremy, all,
Sorry this took so long, spent last week in Japan at OSDL conf then
netconf. After several false starts, I ended up with a very simple
implementation, which clashes significantly with your work since then
8(. I've pushed the patches anyway, but it's going to be significant
work for me to re-merge them, so I wanted your feedback first.
The first patch simply changes

[patch 0/6] i386 gdt and percpu cleanups
Hi Andi,
This is a series of patches based on your latest queue (as of the
other day, at least).
It includes:
- the most recent patch to compute the appropriate amount of percpu
space to allocate, using a separate reservation for modules where
needed.
- make the percpu sections page-aligned, so that percpu variables can
be page aligned if needed (which is used by gdt_page)

[PATCH 1/3] Bogus tls from gdt
The per-CPU initialization code is copying in bogus data into
thread->tls_array. Note that it copies &per_cpu(cpu_gdt_table, cpu),
not &per_cpu(cpu_gdt_table, cpu)[GDT_ENTRY_TLS_MIN). That is totally
broken and unnecessary. Make the initialization explicitly NULL.

[PATCH 0/25][V3] pvops_64 last round (hopefully)
This is hopefully the last iteration of the pvops64 patch.
>From the last version, we have only one change, which is include/asm-x86_64/processor.h: There were still one survivor in raw asm.
Also, git screwed me up for some reason, and the 25th patch was missing the new files, paravirt.{c,h}. (although I do remember having git-add'ed it, but who knows...)
Andrew, could you please push it
