This patch adds a missing privop definition for ia64_trace_syscall
when CONFIG_XEN is unset. It also cleans up some inconsistent
spacing.

This small patch intends to fix domain pause/unpause bug.
Current xm pause operation will do sync_vcpu_execstate to
sync vcpu status, but it saves dom0's fpu and other registers
to VTi domain or domainU due to xm pause from control panel.
Because sync_vcpu_execstate was called after vcpu_sleep which
has saved all status when schedule out ,in addition, currently
no lazy states need to be saved in IPF side, so sync_vcpu_execstate
would need do nothing now.

This patch will fix VTi domain destroy bug. On tip, we couldn't
destroy VTi successfully at times. It was caused by misusing
vhpt base address for VTi domain in vhpt_flush function.

This script automates merging the sparse tree to new upstream
kernel revisions. When possible the files are automatically
patched to the new version, if that fails, the xen and upstream
patches are tried in reverse order, if that fails, the method
producing the smallest reject is left for manual merging.
Run as:
# LINUXPATH=$HOME/linux-2.6 sparse-merge
Where LINUXPATH is a local mercurial tree of the upstream kernel
(available from http://www.kernel.org/hg/linux-2.6). NEWTAG and
OLDTAG may also be specified if the autodetection does not work.
By default, NEWTAG will be the latest upstream version. If NEWTAG
or OLDTAG is an extra-version (ex. 2.6.16.13), ketchup will be
used to update the mercurial tree and add the appropriate tag.

Allow multiple-time mmap of the privcmd device. The old implemntation
doesn't allow multiple-time mmap for a same struct file_struct.
However xend or qemu does multiple-time mmap.
This patch affects only dom0 vp model. With this patch multiple domu can
boot simultaneously and vti domain can boot on vp model dom0.

This patch intends to provide mechanism for clearing rse invalid
partition before rbs switch to guest. To avoid leaking hypervisor
bits to guest, it is a must to clear registers which are in
invalid partition before leaving hypervisor.

This patch modifies the interruption handler to display the
information about the interruption and then do panic in the case of the
fault occurred in hypervisor, or reflect to the guest when handling the
fault in guest.
The modification is as follows:
1. In each handler in IVT, the procedure is added to branch to fault
handler or reflection according to ipsr.cpl.
2. In the case of the fault occurred in hypervisor(ipsr.cpl==0), the
fault handler displays the information (vector, registers, and stack by
calling show_registers()), and then do panic().
3. In the case of the fault occurred in guest(ipsr.cpl!=0), it is
reflected to the guest.
With this modification, some faults which were always treated to be
reflected to the guest are changed to do panic when they occur in
hypervisor.
