Paolo Bonzini 59bc10ee01 finish VPATH -> vpath translation
This adds a few more vpath suffixes and points the remaining two paths
explicitly to $(SRC_PATH) in order to eliminate the VPATH assignment
from config-host.mak.

Andreas Färber 0e8c9214ba Drop --whole-archive and static libraries
Juan has contributed a cool Makefile infrastructure that enables us to drop
static libraries completely:

Move shared obj-y definitions to Makefile.objs, prefixed {common-,hw-,user-},
and link those object files directly into the executables.

Replace HWLIB by HWDIR, specifying only the directory.

Drop --whole-archive and ARLIBS in Makefiles and configure.

Drop GENERATED_HEADERS dependency in rules.mak, since this rebuilds all
common objects after generating a target-specific header; add dependency
rules to Makefile and Makefile.target instead.

v2:
- Don't try to include /config.mak for user emulators
- Changes to user object paths ("Quickfix for libuser.a drop") were obsoleted
  by "user_only: compile everything with -fpie" (Kirill A. Shutemov)

v3:
- Fix dependency modelling for tools
- Remove comment on GENERATED_HEADERS obsoleted by this patch

Anthony Liguori 20ff6c8066 Do not abort on qemu_malloc(0) in production builds
qemu_malloc() does not allow size=0 to be passed in and aborts on this behavior.

Unfortunately, there is good reason to believe that within qemu, there are a
number of, so far, undetected places that assume size=0 can be safely passed.
Since we do not want to abort unnecessarily in production builds, return
qemu_malloc(1) whenever the version file indicates that this is a production
build.

Alexander Graf 0e60a699d2 Add KVM support for S390x
S390x was one of the first platforms that received support for KVM back in the

enable users to actually run guests.

Michael S. Tsirkin be17dc90b5 configure: use correct cflags in compiler checks
linux-user build on fedora 11 breaks because fallocate
is broken on that system if -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64
are specified, which is what QEMU uses.

We do have a configure check to catch this and disable fallocate,
however, it turns out that default QEMU_CFLAGS/LDFLAGS were assigned in
script *after* all compiler checks: so during checks we were not running
compiler with same flags that we used for build later.

Fix this by moving QEMU_CFLAGS to before compiler checks, and using
comple_prog when checking for fallocate.  This also fixes the fact that
we do some compiler checks while assigning the flags, right below a
comment that says "no cc tests beyond this point".

Aurelien Jarno afa05235a5 tcg: initial mips support
Based on a patch from Arnaud Patard (Rtp) <arnaud.patard@rtp-net.org>

A few words about design choices:
* Two registers, at and t0, are reserved for TCG internal use. They are
  useful for bswap and 64-bit ops.
* Most ops supports a constant argument with value 0, which is actually
  mapped to the zero register.
* While the at register is available for constant loading, ops only
  support a limited range of constants. TCG does a better job doing the
  register allocation and constant loading by itself. There are plenty of
  registers available anyway.

Markus Armbruster eb852011ab Configurable block format whitelist
We have code for a quite a few block formats.  While I trust that all
of these formats are useful at least for some people in some
circumstances, some of them are of a kind that friends don't let
friends use in production.

This patch provides an optional block format whitelist, default off.
If a whitelist is configured with --block-drv-whitelist, QEMU proper
can use only whitelisted formats.  Other programs, like qemu-img, are
not affected.

Drivers for formats off the whitelist still participate in format
probing, to ensure all programs probe exactly the same.  Without that,
QEMU proper would be prone to treat images with a format off the
whitelist as raw when the image's format is probed.

Anthony Liguori 2d9f27d2fd Fix the build when srcdir == objdir
You would only see this error on a fresh clone when srcdir == objdir.  configure
will fail because roms/pcbios doesn't exist.

git submodule integration doesn't cleanup very well when switching between
branches so you'll get an roms/pcbios directory from normal operations if you
switch between old branches.

Thanks to a mistake in configure, if you build outside of srcdir, you'll also
get a valid roms/pcbios.
