There are two definitions of raw_smp_processor_id()
One is in file xen/include/asm-ia64/linux/asm/smp.h
#define raw_smp_processor_id() (current_thread_info()->cpu)
The other is in file /xen/include/asm-ia64/config.h
#define raw_smp_processor_id() current->processor
In fact, the first one takes effect, that's not correct.

This patch is to remove more unused linux files inside xen and also some
duplicated ones, like slab.h and cpumask.h. This should help reduce
duplicated definitions conflicting with xen's.

make dtlb miss handler to handle xen/ia64 identity mapping area.
xen/ia64 enables vhpt walker for all regions unlink Linux.
So dtlb misses on identity mapping area are catched by
dtlb miss handler, not alt dltb miss handler.
- dtlb miss on identity mapping area must be handled
- alt dtlb miss must be handled
- itlb miss on the identity mapping area must not occur
panic via page_fault().
- alt itlb miss by a guest must be handled
it occurs during dom0 boot.
- alt itlb miss by xen must not occur
panic by FORCE_CRASH
vmx_ivt.S already has such tweaks by checking psr.vm bit.
TODO: optimization
dtlb miss handlers are performance critical so that
it should be heavily optimized like alt_dtlb_miss.

This patch handles the pal_freq_ratio and pal_freq_base request breaked
to Xen by GFW for VTi domain. and it fixed the wrong frequency ratio
and base of VTi domian. So,i with this patch, VTi domian can get the
right time ,itc,cpu frequency, freqency base and other kernel params rely
on right frequency_ratio.

functionality as we test other guests.
The SVM needs the equivalent changes to the vmc.c to get this
functionality working, but this patch does not break the build.

Previously when switching to idle domain, cr.pta is set to dom0's VHPT,
then when switching from VTIdomain to idle domain, cr.pta is set to
dom0's VHPT, and in idle domain, VHPT will be not remapped by TR, so
there may be unexpected vhpt fault in idle domain, which may cause
domain crash. Above only happens in host smp platform not host up
platform. This patch is intended to fix this bug.

Fix Reserved Register/Field fault in sal_emulate().

I'm making a patch for domain destruction.
While I tested my patch by repeatedly
creating/destructing domains,
a reserved register/field fault occurred in load_region_regs().
The cause of this fault is rr0 value overflow(0xFFFFFFFF********)
because metaphysical_rr0 in the arch_domain struct is
declared as integer (should be unsigned long).
The attached patch fixes the problem.

Update the documentation to include the syntax of "hiding" a PCI
device from domain 0 and for specifying the assignment of a PCI device
to a driver domain. It also includes a brief section exploring some of
the security concerns that driver domains address and mentioning some
of those that remain.

Replace the old pciif DevController class with a new one that
configures the PCI backend. A util class detects the resource usage of
the specified PCI devices and pciif interacts with Xen to permit a
driver domain to directly access those physical I/O resources.

I also added a one-liner that causes xenbus_dev_(error|fatal) to output
to the kernel log buffer (and thus syslog) which was invaluable to me
while debugging (by default, error messages only appear in xenstore).
