x86, shadow: Fix OOS on domain crash.
I couldn't reproduce the Nevada crash on my testbox, but this should
fix the first Xen crash that was seen in the Nevada HVM (bugzilla
#1322).
What I think most probably happened there is that the set_l2e call in
shadow_get_and_create_l1e() has tried to resync a page, but somehow we
weren't unable to remove the shadow (the real bug we should actually
look after). sh_resync() then removes the page from the OOS hash and
later in the page fault path we find the gw.l1mfn to be still OOS, so
we try to update the snapshot and the bug happens.
This should fix this and other unlikely (like sh_unsync() failing to
remove for hash collision the current gw.l1mfn) cases.

ia64: PV driver domains - ugly python hacks
x86 IOMMU support added a lot of assumptions about what PCI buses look
like and where to find bridge devices. On ia64, we don't yet have
virtualization friendly IOMMUs, so for the moment, we just want to
keep "unsafe" PV PCI pass through working as well as it did in Xen
3.2. Looking at the code, it almost seems like x86 has thrown out
support for the old style driver domain. Things that don't
necessarily work on every PCI compliant architecture:
* You can't assume that just because there's a device at 01:01.0
that there's also a bridge at 01:00.0 and blow-up when you
don't find it. On HP ia64 boxes, PCI root bridges are not
necessarily exposed as a PCI device. This pretty much means
we can't call into any of the "FLR" code paths.
* BAR alignment: it's hard to have BAR alignment when your page
size is 16k. This wasn't a requirement for previous PV driver
domains, so I assume it's only for IOMMU support.
This is ugly, so I'm open to suggestions. It seems that all of these
architecture checks could be replaced by checking some "iommu_present"
variable to test whether the extra requirements are necessary.

It seems brace expansion is not available in some environments, so we
had better avoid using it.

ioemu, passthrough: fix flag for expansion rom base address register.
pt_bar_reg_parse() is called for expansion rom base address register.
Currently it returns PT_BAR_FLAG_MEM if bit 0 is 0. It returns
PT_BAR_FLAG_IO if bit 0 is 1.
But bit 0 in expansion rom base address register is enable bit. If bit
0 is 1 for some reason, it returns PT_BAR_FLAG_IO. Expansion rom is
mapped to memory space. It should return PT_BAR_FLAG_MEM.
After applying this patch, it returns PT_BAR_FLAG_MEM regardless
of bit 0, when it is called for expansion rom base address register.

ioemu, passthrough: fix writing handlers for base address registers.
This patch fixes writing handlers for base address registers (include
expansion rom base address register) as follows.
It can be applied to both ioemu-remote and ioemu.
- Current implementation can not work fine when base address registers
are accessed via 1 byte write access and 2 byte write access. This
patch enables them.
- Currently guest software can set address which is not aligned
with resource size and page size. The patch does not allow guest
software to set unaligned address.
