kfraser@localhost.localdomain dfddb95579 [XEN] Make memory hypercalls NUMA-aware. 
This patch modifies memory ops to use the NUMA-aware page allocator
functions.  We use the target domain's VCPU0 placement to determine
which node's memory to use.  We expect the system administrator to
utilize the exposed NUMA topology information to help craft guest
config files that are NUMA-friendly (use only processors and memory values
that will fit within a given node).

kfraser@localhost.localdomain f0738d2d3f [XEN] NUMA-ify Xen heap and page allocator 
This patch adds a per-node bucket to the heap structure in Xen.
During heap initialization the patch determines which bucket to place
the memory. We reserve guard pages between node boundaries in the case
that said boundary isn't already guarded by the MAX_ORDER boundary to
prevent the buddy allocator from merging pages between nodes.

kfraser@localhost.localdomain fcf4e106d0 [HVM] Move ACPI timer to HV, which is the last platform timer in Qemu. 
We found Vista polls ACPI timer very frequently (about 15 times
averagely) when handling timer (RTC @ 64HZ) interrupt routine. Though
the exact reason is known, it should be related to system time
adjustment. When it's in Qemu, the overhead is big. After moving,
Vista's idle overhead decreases dramatically from ~10% to 0.9%.=20

Another benefit is that Vista can only pass Performance rating with
this patch. The root cause is that ACPI timer in Qemu isn't
synchronous with other platform timer in HV, which results in Vista
complains "can't measure TSC frequency".

This patch changes vpit.h to vpt.h, for it not only has pit structure
in it, but other platform timer's structure. Another change is moving
ACPI timer and related address from acpi.h to ioreq.h, which can be shared
by HV and ACPI firmware.

kfraser@localhost.localdomain 94e4fb8a1d [BLOCK] blkback: Fix potential grant entry leaks on error

If one of the earlier entries fail to be mapped, it can cause all
subsequent entries to be leaked if they were successfully mapped.

This patch changes it so that we will continue to reap grant entries
