  SLES9 has a problem with it's <asm/elf.h> and other headers associated

  don't need) we can just stop including it.

[PATCH] vmx-worldswitch-1-to-1.patch

Fix VMX world switch to use 1:1 page tables when the guest has paging
disabled. Also do a printk instead of VMX_DBG_LOG() anytime we crash
a domain.

[PATCH] xen-libxc-static-build.patch

Fix build of the static library.

As it was depending on an undefined objects variable (OBJS), its
dependency list was null and thus it ended up empty.

Also optimize the depedency checking so we don't need a submake. Not
too great an optimization, but it makes it short :)

[PATCH] xen,tools: pincpu use vcpu and cpumap_t

The following patch updates the dom0 pincpu operation to read the VCPU
value from the xend interface rather than hard-coding the exec_domain to
0.  This prevented pinning VCPUS other than 0 to a particular cpu.  The
pincpu cpu argument is replaced with cpumap, a u64 bitmap representing
which CPUs a VCPU can use.

I added the number of VCPUS to the main xm list output and also included
a new sub-option to xm list to display the VCPU to CPU mapping.  While
working on the pincpu code, I fixed an out-of-bounds indexing for the
pincpu operation that wasn't previously exposed since the
vcpu/exec_domain value was hard-coded to 0.

[PATCH] [PATCH] Assorted VMX patches

This patch contains the following VMX patches:

- ioemu: Update the address when doing a stosb/stosw/stosl. Without this patch
  stosb writes req->count times at the same location req->addr. Not exactly
  the intended semantics.

- xc_ptrace.c: Use the page_array to refer to partition memory. This allows
  you to use gdbserver on a VMX partition (and presumably partitions that use
  shadow page tables).

- dom0_ops.c: Preserve ECF_VMX_GUEST flag for gdbserver. Without it you
  cannot (re)set the VMX domain state.

- vmx.c: Added support for lmsw. Unmodified FreeBSD uses this when running
  inside a VMX partition.
