This patch fixes the case where a module line is supposed to be added
to the very end of the file but the file does not end in with a new
line. Also fixes a problem that in some cases the module line would
not be properly be removed.

delivered 'off beat' immediately upon re-scheduling when ticks are
missed, then reverting to delivering ticks 'on beat' as usual.

- Get rid of PAGE_SIZE usage in arch-ia64.h when building tools.
- Now that more of xen_init_fv is identical to x86 code, share the
code rather than duplicate it.
- Change a few things that came over from the ia64 tree to use the
XC_* macros as already done upstream.

- Update comment in copy_rbs()
- Don't warn when rbs_size = 0 for cpu initialization case.
- Remove struct vcpu_guest_context_regs::rbs_nat member which isn't used.
and add num_phys_stacked to struct vcpu_guest_context_regs.
so far rbs_nat and rbs_rnat isn't, so it is allowed to change the offset
of rbs_rnat.
- Add check when setting vRR[].
- Don't set vRR[] if val is zero.

Inter-domain shared interrupt has been supported by timeout method,
but it still doesn't support intra-domain shared interrupt, that is
assigning multiple devices which share a physical irq to the same
domain. This patch implements intra-domain shared interrupt
support. In addition, this patch maps link to guest device/intx
instead of directly mapping isairq in pt_irq_create_bind_vtd(),
because at this point the isairqs got from pci_link are always 0.
Note that assigning multiple devices to guests which uses PIC to
handle interrupts may be failed, because different links possibly
connect to same irq.

When we losetup a file on readonly nfs filesystem, it fails with:
# losetup /dev/loop7 /data/vm/xen_el5_i386_para/system.raw
/data/vm/xen_el5_i386_para/system.raw: Permission denied
New version of losetup has add a "-r" option for readonly loop, which
Linux kernel has supported for a long time. Some distribution (EL5
update, Fedora 8, etc.) have shipped it. This patch benefit this
option while doesn't break the old versions of losetup.

When xm block-detach command was done on PV-ON-HVM, the response of
other disks was lost. It is because a wrong event channel was
invalidated when detaching it. Not the evtchn number but the irq
number is invalidated specifying it.

Xen cannot work when xenstored's tdb is corrupt. When that happens
somehow (and we've seen it happen), even reboot doesn't recover from
it. It could: there is no state in tdb that needs to be persisted
across reboots.
This patch arranges that tdb is removed before xenstored is started,
provided it doesn't already run. This is safe, because:
* xenstored cannot be restarted. If it dies, Xen's screwed until
reboot.
* /usr/sbin/xend always starts xenstored anyway.
* xenstored locks its pid-file (see write_pidfile() in
tools/xenstore/xenstored_core.c), and refuses to start when it
can't.
* My patch makes /usr/sbin/xend remove tdb iff it can lock the
pid-file. In other words, it removes tdb only when xenstored is not
running, and locks it out until it is done.
Bonus fix: it also removes stale copies of the tdb xenstored tends
to leave behind when it exits uncleanly.
