This patch changes to format in which EIP is printed to be consistent on 64-bit regardless of whether the addresses
leading bits are set or clear. It additionally changes the formatting so that trailing spaces are avoided, and it
suppresses the printing of empty records. It also prevents combining records with identical EIP but from different
domains.
It further changes the type of some variables from plain int to unsigned int, as that is yielding more efficient code
on x86-64 (signed 32-bit array indices require explicit sign extension, whereas in most cases an extra copy can be
avoided when the index type is unsigned, since all 32-bit operations already zero-extend their results).
This patch conditionalizes some output from perfc_printall(), thus making relevant information more compact and easier
legible. It additionally changes the formatting so that trailing spaces are avoided.
Also changing the type of some variables from plain int to unsigned int, as that is yielding more efficient code on
x86-64 (signed 32-bit array indices require explicit sign extension, whereas in most cases an extra copy can be avoided

Move Linux-specific privcmd code into private libxc implementations.
Make header path for kernel's privcmd/evtchn headers generic.
Remove pointless xi_*() interface that was using private libxc
interfaces.
Fix x86/64 version of Mini-OS. It encompasses the following:
a) 64-bit switch_to scheduler macro (by Aravindh Puthiyaparambil)
b) implements 64-bit hypervisor_callback
c) fixes thread creation issues (thread_starter used to perform
initialisation)
Change semantics of grant transfers for vp guests so that the
operation automatically gets you a fresh page at the same
pseudo-physical address as Keir suggested.
Debugging Xend with XEND_DAEMONIZE set to False doesn't work as
expected. Xend actually creates two children and the XEND_DAEMONIZE
flag only prevents one of the children from being created. This
patch causes none of the children to be created. With this patch,
Xend functionality is performed in the process executed from the
command line (i.e., /usr/sbin/xend). This patch makes it possible to
debug Xend with pdb.
Define new event-channel and physdev hypercalls with a more extensible
interface (the legacy hypercalls would break if subcommands with large
argument structures were added, as it would grow the size of the
union of all argument structures).
Also, based on a patch from Kevin Tian, add a new physdev op to
signal EOI for a particular irq.
Wait for the device to be connected on the guest (with a 10s timeout)
before detaching it. Fix a race condition that dom0 was tearing down the
block device while the guest was putting it in a Connected state.

xen/ia64 with dom0 vp model doesn't need the blkbkack ia64 workarounds
any more. xen/ia64 dom0 vp model is a big change so that xen/ia64
with the old model (P=M) still remains as the compile option.
Hopefully the work around will be eliminated in the future completely.
When boot device is cdrom but the cdrom is not bootable, the guest appears
to hang. This patch fixes this by filling in second- and third-priority
fallback boot devices.
This patch fixes the buildroot for the xm-test ramdisk. The buildroot xm-test
was getting is no longer there, they've pruned the snapshots. This patch
adds a new buildroot and updates the buildroot configuration. I also
incremented the xm-test release version to 0.8.

Instead of relying on xm create to always run the bootloader, make sure
we run it if we get into domain creation with a bootloader set but no
image. This could happen if someone creates a domain config via the
XML-RPC or sxp interfaces.
The features for a domain are more a property of the domain than the
image. Move them into the domain info so that the image is just the
pieces needed for booting (eg, kernel + initrd + args)
When building with FORTIFY_SOURCE to ensure that return codes of common
functions are checked to avoid some bugs, a few warnings pop up and
become errors due to -Werror. Attached checks the return codes
(or at least stores them to a dummy variable).
Relax BUG_ON() state ment in increase_reservation() in balloon.c.
When xen_feature(XENFEAT_auto_translated_physmap) = 1,
phys_to_machine_mapping_valid(pfn) always returns true.
Relaxed BUG_ON() for xen_feature(XENFEAT_auto_translated_physmap) = 1 case.
Define __XEN_TOOLS__ when building tools. Use this to
automatically build against latest Xen interface version,
and to specifically define GET_XEN_GUEST_HANDLE().
Occasionally large smp machines fail to reboot properly and die under
an IPI storm of smp_call_function() to machine_reboot. Only the boot
processor needs to run machine_restart, so send an IPI to CPU0.
This patch adds the ability to have restricted write access to some
of the structures on the capability list. Specifically, this patch adds
support for reading data through the Vital Product Data capability
structure and for manipulating power management of a card. A driver
domain is not allowed to enable Power Management Events (the PME trace
may be shared across devices in many domains), but it can put a device
in its control to sleep or query it for power usage statistics. This
code could possibly be expanded in the future to add support for AGP,
PCI-X, and MSI/MSIX (all of which are controlled through structures on
the capability list).
This patch also corrects some formatting issues in the PCI backend and
adds some comments to the code regarding permissive mode.
This patch addresses CVE-2006-1056 (information leak from
fxsave/fxrstor on AMD CPUs) and also adjusts 64-bit handling so that
full 64-bit RIP/RDP values get saved/restored. More fine-grained
handling may be needed if 32-bit processes are expected to properly
see their selectors (native Linux doesn't currently do that either,
but there is a patch to adjust it there).

xenLinux/ia64 has its own dma_map_page(), dma_unmap_page(), and it needs
linux default implementations of dma_declare_coheremnt_memory() and its
families which is defined in include/linux/dma-mapping.h.
So those in pci-dma-xen.c are unnecessary. #ifdef out them.

[IA64] Fix the total memory info with xm info command
This small patch intends to provide correct total memory info for
control panel and fixed hardcode for that. The total memory info doesn't
include the memory FW used.
Move contents of switch_to macro from xensystem.h to context_switch function.
Initialize FPU on all processors. FPH is always enabled in Xen.
Speed up context-switch (a little bit!) by not enabling/disabling FPH.
Cleanup (unused function/variablesi/fields, debug printf...)
vmx_ia64_switch_to removed (was unused).
This small patch output message of elf_sanity_check as x86.
Currently this panic is the only following message.

Some of the Linux PCI functions called by the virtual configuration
space handlers were making calls into ACPI code which uses semaphores.
Since semaphores can not be locked while atomic (because they could
sleep), I changed the way the PCI backend responds to requests from the
frontend. Previously, the virtual configuration space handlers ran in
the same context as the event channel interrupt handler (which was often
atomic if not always atomic). Now the interrupt handler schedules a
callback function (a bottom half) in the system work queue (keventd)
that will get called in process context at a slightly later time. This
allows the handlers in the virtual configuration space to run in process
context and to call any core PCI function regardless of whether it will
sleep or not.
While other aspects of the system configuration may still be
controlled by the outcome of the table scan, if apic= was given on the
command line its effect should not be overridden here.
This is a small fix for SMP PAE guest on x86-64.
Since part of the VMX guest initialization is running in the context of
dom0, so when we want to make sure the operation of shadow ops is
always done by vcpu0 of the guest VMX domain, we should make sure
the current vcpu0 is running in guest domain and not in the dom0.

This patch updates the documentation and extends the 'xm' man page with
the integrated access control management commands. The man page is a
good place to start exploring these commands.
This patch integrates the new access control management tools into 'xm'
and 'xend' and supports label/ssid translation support for
migration/life-migration/resume.
This patch adds new python access control management scripts, which
integrate into Xen Management and which support the new access control
labels (labels replace the ssidref numbers at the management user
interface).
