Keir Fraser c5699e2771 x86: Add cpufreq logic to S3 suspend/resume
When suspend to S3, stop the cpufreq dbs governor. When resume from
S3, firstly sync cpu state and freq at the 1st dbs timer; from 2nd dbs
timer on, cpufreq dbs governor control cpu px transfer according to
its workload algorithm. Px statistic is also handled.

Keir Fraser bbc24abfb2 tools/python: blkdev_name_to_number fixes
Rework blkdev_name_to_number to allow the tools to attach xvd disks
beyond xvdp.

 1.  Adds the handling for the /dev/xvd[q-z] and /dev/xvd[a-i][a-z]
     extended devices

 2.  Changes blkdev_name_to_number() to return a tuple of (xenbus,
     devnum), and then deals with the resulting fallout.

Keir Fraser da43e50cb3 hvm rombios: Move function calls out of 'post' function section
Through recent additions to the rombios the code section of the post
function has filled up considerably. When I enable the BX_TCGBIOS
compile time option the BIOS crashes since the post section code
(starts at $e05b) spills over into the nmi entry point (starts at
$e2c3). as86 doesn't cause an error when building.

Keir Fraser fd9d7bdc9e AMD PowerNow! in Xen
This patch set moves support for AMD's PowerNow! technology from
dom0 into the hypervisor, now that there is support for
transferring ACPI data to the hypervisor.  It will only work for
AMD processors that support the architectural P-state driver,
such as 3rd generation Opterons, Phenoms, and Turion Ultras.

This patch creates the Architectural P-state driver inside
of the Xen hypervisor and hooks it into the Xen code.  It
has been tested at AMD with a variety of para- and fully-
virtualized guests for a week without regressions.

Keir Fraser c385f786c2 vmx: Clean up and fix guest MSR load/save handling:
1. msr_bitmap/msr_area/msr_host_area must be freed when a vcpu is
    destroyed
 2. vmx_create_vmcs()/vmx_destroy_vmcs() are only ever called once,
    and can hence be simplified slightly
 3. Change vmx_*_msr() interfaces to make it crystal clear that they
    operate only on current (hence safe against vmwrite() and also
    against concurrency races).
 4. Change vmx_add_*_msr() implementation to make it crystal clear
    that msr_area is not dereferenced before it is allocated.

Only (1) is a bug fix. (2)-(4) are for code clarity.

Keir Fraser cc5871d6da ioemu: generic PCI device config-space emulation
This patch is an extension for qemu-dm to enable emulation of generic
PCI devices. The information for the PCI devices can be passed by
command line parameter.

The command line parameter is "-pciemulation" followed by the
information which contains a label and hex value of the configuration
registers separated by ":".

The configuration registers for each PCI device are below.
vendorid
deviceid
command
status
revision
classcode
headertype
subvendorid
subsystemid
interruputline
interruptpin

This is an example of command line parameter.

patch to make it work on x86_64 and port it to Mini-OS.  By using

domain itself, hence permitting to avoid the security-concerned
pygrub.
