To make good use of transparent hugepages, KVM requires that guest-physical

12 bits normally required).

Adjust qemu_vmalloc() to honor that requirement.  Ignore it for small regions
to avoid fragmentation.

Qemu currently assumes that chtype is typedef'd to unsigned long, but
this is not necessarily the case (ncurses, for instance, can configure
this at build-time).  This patch uses the predefined chtype if qemu is
configured for curses support and falls back to unsigned long otherwise.

Adding a 2nd balloon device after unplugging the first one doesn't work.
Also, the 'info balloon' command should indicate an error mentioning no
balloon device is registered after unplug.

(qemu) info balloon
balloon: actual=4096

The ppc64 code generation backend uses an rldicr (Rotate Left Double
Immediate and Clear Right) instruction to implement zero extension of
a 32 bit quantity to a 64 bit quantity (INDEX_op_ext32u_i64).  However
this is wrong - this instruction clears specified low bits of the
value, instead of high bits as we require for a zero extension.  It
should instead use an rldicl (Rotate Left Double Immediate and Clear
Left) instruction.

Presumably amongst other things, this causes the SLOF firmware image
used with -M pseries to not boot on a ppc64 host.

It appears this bug was exposed by commit
0bf1dbdc (tcg/ppc64: fix 16/32 mixup)
which enabled the use of the op_ext32u_i64 operation on the ppc64
backend.

Previously, the address space soft limit was set mcache_max_size. So,
before the mcache_max_size was reached by the mapcache, QEMU was killed
for overuse of the virtual address space.

This patch fix that by setting the soft limit the maximum than can have
QEMU. So the soft and hard limit are always set to RLIM_INFINITY if QEMU
is privileged.

In case QEMU is not run as root and the limit is too low, the maximum
mapcache size will be set the rlim_max - 80MB because observed that QEMU
use 75MB more than the maximum mapcache size after several empirical
tests.

This patch removes redundant shell code and cleans it a little bit.

Shell macro compile_prog takes two arguments:
local_cflags and local ldflags.

$QEMU_CFLAGS is added automatically to the cflags, so there is no need
to pass it as an argument.

It is also unnecessary to pass -Werror twice.

$flag is a compiler warning option, so it should be in local_cflags
instead of local_ldflags.

This patch makes qemu assign a port when creating the device, not when
attaching it.  For most usb devices this isn't a noticable difference
because they are in attached state all the time.

The change affects usb-host devices which live in detached state while
the real device is unplugged from the host.  They have a fixed port
assigned all the time now instead of getting grabbing one on attach and
releasing it at detach, i.e. they stop floating around at the usb bus.

The change also allows to simplify usb-hub.  It doesn't need the
handle_attach() callback any more to configure the downstream ports.
This can be done at device initialitation time now.  The changed
initialization order (first grab upstream port, then register downstream
ports) also fixes some icky corner cases.  For example it is not possible
any more to plug the hub into one of its own downstream ports.

The usb host adapters must care too.  USBPort->dev being non-NULL
doesn't imply any more the device is in attached state.  The host
adapters must additionally check the USBPort->dev->attached flag.
