acpi_sleep_info is changed but some of the code in Xen is not
synchronized up with this change, which causes Xen S3 failure.

The automatic NUMA placement code (find_relaxed_node) in
XendDomainInfo.py contains several bugs:
1. The domain just created shall not be considered in the load
calculation.
2. Nodes with too less memory for the domain must be considered during
the load calculation phase and abandoned later, currently these nodes
win with a load of 0.
3. CPUs which are offline shall not be considered in load calculation.
4. (Integer-)Dividing the load value by the number of cores per node
may conceal subtle load differences resulting in a non-optimal node to
be chosen.

- add S3 package in ACPI DSDT table. Guest OS will get S3 value from
this package and write the value to PM1A control register to
trigger S3 suspend.
- Add S3 resume logic in rombios post code. the CMOS shutdown register
is used to indicate if this is a S3 resume.
- if it is s3 resume, rombios will get wakeup vector from ACPI FACS
table and jump to wakeup vector. Per ACPI spec, the wakeup vector
jumping must be the forms CS:IP, in which CS=3D(wakeup vector>>4)
IP=3D(wakeup vector)&0xF, for example, for vector=3D0x12345,
CS:IP=3D0x1234:0x5
Note: clobber_entry_point will clobber the post entry, which make S3
resume not work. We will directly jmp to POST Entry if it in S3
Resume path.

Changeset 17289:d97e61001d81: introduced vfb configuration parameter
videoram, defaulting to zero. Value zero was interpreted as
unlimited. Changeset 17630:53195719f762 accidentally dropped the
special case for zero, which broke guests that don't specify videoram,
or specify videoram=0. Restore the old behavior.

This patch fixes several bugs in serial.c
(1) A typo in serial_save() where qemu_get_8s is called (should be
qemu_put_8s)
(2) No support provided in serial_load() for version_id == 1 (should
unmarshal a 1 byte s->divider and should provide a default value
for s->fcr)
(3) Call serial_ioport_write() to initialize s->fcr. It is not
sufficient to load its value; other hidden values (such as
s->recv_fifo.itl) must be re-initialized.

1. use jump table to dispatch virtualization faults.
2. for virtualization faults, handler is executed with psr.i=0, psr.ic=0,
psr.bn=0. less context switch.
3. use register stack instead of memory stack to switch context.
4. Use C code to handle faults as possible, to reduce maintanance efforts,
remove assembly handlers for rsm , ssm, mov to psr, mov to rr.
5. add fast path C handler for rsm, ssm, mov to psr, rfi.
