util/mmap-alloc: fix hugetlb support on ppc64

util/mmap-alloc: fix hugetlb support on ppc64

Since commit 8561c9244ddf1122d "exec: allocate PROT_NONE pages on top of
RAM", it is no longer possible to back guest RAM with hugepages on ppc64
hosts:

mmap(NULL, 285212672, PROT_NONE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0x3fff57000000
mmap(0x3fff57000000, 268435456, PROT_READ|PROT_WRITE,
MAP_PRIVATE|MAP_FIXED, 19, 0) = -1 EBUSY (Device or resource busy)

This is because on ppc64, Linux fixes a page size for a virtual address
at mmap time, so we can't switch a range of memory from anonymous
small pages to hugetlbs with MAP_FIXED.

See commit d0f13e3c20b6fb73ccb467bdca97fa7cf5a574cd
("[POWERPC] Introduce address space "slices"") in Linux
history for the details.

Detect this and create the PROT_NONE mapping using the same fd.

Naturally, this makes the guard page bigger with hugetlbfs.

Based on patch by Greg Kurz.

Merge remote-tracking branch 'remotes/mst/tags/for_upstream' into staging

virtio, pc, memory: fixes+features for 2.5

New features:
This enables hotplug for multifunction devices.
Patches are very small, so I think it's OK to merge
at this stage.

There's also some new infrastructure for vhost-user testing
not enabled yet so it's harmless to merge.

I've reverted the "gap between DIMMs" workaround, as it seems too risky, and
applied my own patch in virtio, but not in dataplane code. This means that
dataplane is broken for some complex DIMM configurations for now. Waiting for
Stefan to review the dataplane fix.
