The original /dev/mem (linux/drivers/char/mem.c) is aware of IA64
specific issues. On the other hand paravirtualized /dev/mem
(linux-2.6-xen-sparse/drivers/xen/char/mem.c) is simplifed not to be
aware of IA64. This patch makes it IA64-aware to use X on domain0/IA64.
With this patch and ia64-specific patches, X server can boot on domain0/IA64.

arch/x86/mm.c and arch/x86/sched.c. Header files were also refactored:
arch specific code got moved to include/x86/arch_mm.h and
include/x86/sched_mm.h.

buffer support and auto translated mode support.
renamed xenoprof_get_buffer::buf_maddr, xenoprof_passive::buf_maddr to
xenoprof_get_buffer::buf_gmaddr, xenoprof_passive::buf_gmaddr
to support auto translated mode. With auto translated mode enabled,
it is gmaddr, not maddr.

TODO:
1. Fix IO-APIC ID to not conflict with LAPIC IDS.
2. Fix i8259 device model (seems to work already though!).
3. Add INTSRC overrides in MPBIOS and ACPI tables so
that PCI legacy IRQ routing always ends up at an
IO-APIC input with level trigger. Restricting link
routing to {5,6,10,11} and setting overrides for all
four of those would work.

devices' state when a VM configuration file is destroyed. Currently only
the vTPM device's state needs to be explicitly destroyed.
I am also surrounding the saving of the managed domain's configuration
with a try-catch.

that it logs everything written to stderr by xc_save and xc_restore as
errors whereas in fact the vast majority of this output is
information/debug (and all actual errors are marked by the string ERROR:
at the start of the message) -- this is confusing to folks looking at
the logs and makes automated log analysis tricky.
Fix is to scan for the ERROR: string and log anything without it using
log.info instead.

This allows us to use the old pagetables's linear maps in our
remove-writeable-mappings heuristics, fixing the same crash that
cset 12339 did, but still letting us do fast revoke of writeable
mappings of toplevel pagetables.

Fixed regression with rebooting domU caused by the change in handling
syncing state from Xen and Xend.
Added missing implementation for XendDomainInfo.unwatchVm() which
disappeared during a merge.
Added protection for console/vnc-port reading for managed domains.

TLB flushing is not done strictly before notifying
the mappee -- this creates scope for multi-processor
mapping guests to attempt to abuse a stale mapping
on another VCPU.

As it stands the 8139C+ TX chaining is only bounded by realloc failure.
This is contrary to how the real hardware operates. It also has DoS
potential when ioemu runs in dom0.
This patch makes any attempt to chain a frame beyond 64K fail
immediately.

1) make vmx/svm time functions hvm common, since they are actually the same.
2) move hvm_send_assist_req from platform.c to hvm.c.
2) rename VMX MSR context switch functions to make them more readable.
3) misc coding style clean ups.

This avoids entering the scheduler with outstanding multicall state
and also happens to simplify the x86 entry protocol to the scheduler
hypercall (since we do not need to preset the return code).
