at the local end of the xenbus connection (i.e. that value that is passed
through xenbus_switch_state). This means that xenbus_probe can wait for all
the boot devices to become ready without having to hurt the store.
Also, fix this probing -- previously, the wrong value was being returned by
all_devices_ready_, so this polling would only have waited for one device.

- machine_specific_memory_setup() was unused on x86-64
- machine_specific_modify_cpu_capabilities() must not be __init (for CPU hotplug)
- machine_specific_modify_cpu_capabilities() should be called in similar ways on 32- and 64-bits

Add comments in public header version.h to explain what all the different
feature flags mean. Add a new flag XENFEAT_pae_pgdir_above_4gb to inform the guest
that its PAE page directories do not need to conform to the usual hardware
restriction.

To support this we give kernel GDT entries DPL=0 and use kernel
segment selectors with RPL=0. Xen will crunch these to ring 1 when
they are passed in. When a segment selector is used directly or placed
in a stack frame the guest OS is reponsible for crunching the RPL.

As a consequence, some of the i386 changes over native code need to also be
added to x86-64.

Add CONFIG_X86_SYSENTER to conditionally include support for sysenter.
Change CONFIG_DOUBLEFAULT to depend on !CONFIG_X86_NO_TSS.
(sysenter and doublefault need tss).

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).

It has been superceded by run-time flag
XENFEAT_auto_translated_physmap.
This patch changes behaviour slightly:
1. set_pmd/set_pgd/set_pud always use mmu_ops, even when
XENFEAT_writable_page_tables is available. Unclear whether
we want to add a test to avoid this.
2. xen_l1_entry_update always uses mmu_op. Again, could gate
this on XENFEAT_writable_page_tables.
3. We always pin/unpin pagetables. Could gate this on a
new XENFEAT flag.

It saves very little space, no distro will disable it
in their unified build, and it's rather a pain to
implement it properly.
I've left the PRIVILEGED_GUEST option for now, as it
provides some indication of where our platform-bringup
hacks are in our Linux tree. We may wish to exclude
those from upstream merge in the first instance.

This boots dom0 and domU on an rx2600.
Revert several files that were accidentally reverted by the merge-ups
(that weren't fixed by cset 8743). Those are included here with the
2.6.15 patch re-applied as well as changes between 2.6.15 and 2.6.16-rc2.
Specifically, these are pal.h, processor.h and system.h.
This patch also reverts changes to include/asm-ia64/hypercall.h and
hypervisor.h from cset 8742.
