Hongxu Jia e609afe4d7 qemu-native:fix do_compile failed on SLED 11.2
1, When build qemu-native on SLED 11.2, there is an error:
...
| In file included from /usr/include/bits/sigcontext.h:28,
|    from /usr/include/signal.h:339,
|    from /buildarea2/tmp/work/i686-linux/qemu-native/1.4.0-r0/
qemu-1.4.0/include/qemu-common.h:42,
|    from fsdev/virtfs-proxy-helper.c:23:
| /usr/include/asm/sigcontext.h:28: error: expected specifier-
qualifier-list before '__u64'
| /usr/include/asm/sigcontext.h:191: error: expected specifier-
qualifier-list before '__u64'
...

2, The virtfs-proxy-helper.c includes <sys/capability.h> and
qemu-common.h in sequence. The header include map is:
(`-->' presents `include')
...
"virtfs-proxy-helper.c" --> <sys/capability.h>
...
"virtfs-proxy-helper.c" --> "qemu-common.h" --> <signal.h> -->
<bits/sigcontext.h> --> <asm/sigcontext.h> --> <linux/types.h> -->
<asm/types.h> --> <asm-generic/types.h> --> <asm-generic/int-ll64.h>
...

3, The bug is found on SLED 11.2 x86. In libcap header file
/usr/include/sys/capability.h, it does evil stuff like this:
...
  25 /*
  26  * Make sure we can be included from userland by preventing
  27  * capability.h from including other kernel headers
  28  */
  29 #define _LINUX_TYPES_H
  30 #define _LINUX_FS_H
  31 #define __LINUX_COMPILER_H
  32 #define __user
  33
  34 typedef unsigned int __u32;
  35 typedef __u32 __le32;
...
This completely prevents including /usr/include/linux/types.h.
The above `<asm/sigcontext.h> --> <linux/types.h>' is prevented,
and '__u64' is defined in <asm-generic/int-ll64.h>.

4, Modify virtfs-proxy-helper.c to include <sys/capability.h>
last to workaround the issue.

Poky
====

Poky is an integration of various components to form a complete prepackaged
build system and development environment. It features support for building
customised embedded device style images. There are reference demo images
featuring a X11/Matchbox/GTK themed UI called Sato. The system supports
cross-architecture application development using QEMU emulation and a
standalone toolchain and SDK with IDE integration.

Additional information on the specifics of hardware that Poky supports
is available in README.hardware. Further hardware support can easily be added
in the form of layers which extend the systems capabilities in a modular way.

As an integration layer Poky consists of several upstream projects such as 
BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information 
e.g. for the hardware support. Poky is in turn a component of the Yocto Project.

The Yocto Project has extensive documentation about the system including a 
reference manual which can be found at:
    http://yoctoproject.org/documentation

OpenEmbedded-Core is a layer containing the core metadata for current versions
of OpenEmbedded. It is distro-less (can build a functional image with
DISTRO = "") and contains only emulated machine support.

For information about OpenEmbedded, see the OpenEmbedded website:
    http://www.openembedded.org/

Where to Send Patches
=====================

As Poky is an integration repository, patches against the various components
should be sent to their respective upstreams.

bitbake:
    bitbake-devel@lists.openembedded.org

meta-yocto:
    poky@yoctoproject.org

Most everything else should be sent to the OpenEmbedded Core mailing list.  If
in doubt, check the oe-core git repository for the content you intend to modify.
Before sending, be sure the patches apply cleanly to the current oe-core git
repository.
    openembedded-core@lists.openembedded.org

Note: The scripts directory should be treated with extra care as it is a mix
      of oe-core and poky-specific files.
