This fixes the problems left behind by c/s 10171. Again pointed
out by Jan Beulich; and again different from his suggested patch.
Hopefully this one will be less embarrassing.

This patch intends to fix isr setting before injecting fault to it.
With this small fix, CPU2000 in VTi can pass now.

This patch fixes several minor issues, as a prepare step to support VGA
acceleration for VTI domain:
- shared vram buffer needs to be mapped as WB in both sides, because
the shared vram is the true WB memory though VTI domain is told as UC
- Introduced a new pte_mem to indicate p2m entry containing valid mfn
when replace p2m entry. Pte_none doesn't work for VTI case, since IO
type is encoded into p2m entry which however doesn't contain valid mfn.
After above change, guest_physmap_add/remove_page is available to
be used by qemu to setup linear buffer for VTI domain.

1. Make Mini-OS start from 0x0.
2. Fixes the pagetable builder to handle half full, but already mapped
pt frames.=20
3. Add a bounds check to ensure than Mini-OS does not try to use Xen
virtual space.

completes the alignment of the ACM call interface with the other Xen
hypervisor call interfaces. This macro is used to call from the a guest
kernel directly into the ACM hypervisor module.

The current shadow mode is not aware of this extra level of shadowing
and gets rather confused. Furthermore it *always* ensures that its
PAE pgdirs are below 4GB so there is no need for the extra shadowing
logic to be invoked.

Now xen drivers use is_running_on_xen() to check whether it runs on
xen or bare metal. There remains many if (running_on_xen) in ia64
specific codes. This patch replaces running_on_xen with is_running_on_xen()

This bug has prevented us from booting fully virtualized SMP guests
that write to the APIC using the xchg instruction (when
CONFIG_X86_GOOD_APIC is not set). On 32 bit platforms, sles 10 kernels
are built without CONFIG_x86_GOOD_APIC not set and hence we have had
problems booting fully virtualized SMP sles 10 guests.

The function cpu_is_allowed() appears that it should return a boolean
but in fact returns zero on success and an errno on failure. Thus
rename it to the more vague cpu_up_check(), in line with its return
value and thge fact it has unspecified side effects.
Fix the macro definition of cpu_up_check() when building non-hotplug
kernel to return zero rather than one (which always failed secondary
cpu bringup!).
