Cleaner GDT interface. Xen now reserves the last 2 pages of a full-size
(16 page) GDT. A guest can register a GDT with up to 7k entries. Xen
automatically makes the GDT up to max size with empty page mappings,
and turns page faults in that area to #GP(selector).

Remove generic 'fast trap' from the Xen public interfaces. Internally
within Xen, we automatically set up direct trap for int 0x80, which is
the only 'fast trap' vector that we ever supported anyway.

[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.
Against latest bk.
Rusty.
Many files:
Merge interface changes from previous 'Split out context fetching into
separate DOM0 op' and 'xen,tools: pincpu use vcpu and cpumap_t' checkins.
xc_linux_save.c:
Undo incorrect change from previous patch.
xc.h, xc_domain.c:
Cleanup whitespace.

[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.

Clean up IO-APIC handling in domain0, and the hypercall interface
exported by Xen (inc. removal of PCI-related calls). This hopefully
fixes acpi=off.

Avoid field duplication between vcpu_guest_context and arch_exec_domain

[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.

Remove memory and cpu parameters from DOM0_CREATEDOMAIN, and remove
DOM0_SETINITIALMEM. You can get the same effect via PINCPU,
SETMAXMEM, and do_mem_op(increase_reservation).

[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
(like those in zap_mmio_ranges) fail and consequently xc_vmx_build fails.
To solve this, this patch pins the l2pt at the end of the function when
all memory initializations are finalized.

Split mmu_update() hypercall into mmu_update() and mmuext_op().
All MMUEXT_* ops are now done via the latter hypercall. This allows
more arguments to be passed in a nicer way to mmuext operations.
Linux 2.4, 2.6 and control tools all use the new interface. The BSDs
will need some work, but shouldn't be too hard (and they can be moved
to writable pagetables at the same time :-) ).
