handle intra-vga-mem copies, as well as log & turn off caching if some

Dom0 C/S 593 hooks the pci bus probe and remove function. When

function. If the probe function fails, another hypercall is called to
remove the device from Dom0's list. But for some RMRR devices, for
example, USB devices, they may still be in use for some operation by
BIOS at booting time. So when removing those kind of devices, we
should still keep the RMRR information.

x86: PIT broadcast to fix local APIC timer stop issue for Deep C state
Local APIC timer may stop at deep C state (C3/C4...) entry. Initial
HPET broadcast working in legacy replacing mode, broke RTC intr, so
was bypassed. This patch add the logic that use platform timer (PIT)
to reenable local APIC timer at C state entry/exit.
Currently, only keep PIT enabled with 100Hz freq. The next step is
trying to dynamically enable/disable PIT while needed, and give it
lower freq.

xend: vt-d: improved FLR logic for pass-thru PCI devices
1) If the device is PCIe endpoint and supports PCIe FLR, we use that;
else
2) if the device is PCIe endpoint, and all functions on the
device are assigned to the same guest, we use the immediate parent
bus's Secondary Bus Reset to reset all functions of the device (here,
actually we require all the functions of the device be assigned to the
same guest); else
3) if the device is PCI endpoint and is on a host bus
(e.g. integrated devices), and if the device supports PCI Advanced
Capabilities, we use that for FLR; else
4) we use the Secondary Bus Reset (if the PCI device is behind a
PCI/PCI-X bridge, then all devices behind the uppermost such PCI/PCI-X
bridge above this device must be co-assigned).

vt-d: Remove the FLR logic in Xen.
The current simple logic has some issues: 1) Dstate transition is not
guaranteed to properly clear the device state; 2) the current code for
PCIe FLR is actually buggy: PCI_EXP_DEVSTA_TRPND doesn't mean the
completion of FLR; according to the PCIe spec, after issuing FLR, we
should wait at least 100ms.
The improved FLR logic will be added into xend.

Choice of network interface for establishing a bridge on if NFSROOT is used
This patch fixes a problem related to machines that are booted using
nfsroot ( '/' provided via nfs). Previously the code was assuming that
nfsroot would be provided via eth0. Now this additional code checks
over which interface the nfsroot is provided after detecting that
nfsroot is actually being used. To determine from where nfsroot is
mounted I am reading the kernel command line (/proc/cmdline) and
filter for an argument starting with 'nfsroot=' and determine the nfs
server's IP address by assuming the format 'nfsroot=<ip
adddress>:<path to root>' - if there's a better way of doing this,
please let me know. After that I determine the interface over which
this IP address would be accessed using 'ip route get <address>'. Then
I compare that interface against a previously determined default
interface and if they are equal return a value that causes an
alternative interface to be chosen.
