Allow compilation of PVonHVM drivers with forward-ported xenlinux sources in openSuSE 12.2. Since Linux 3.4 asm/system.h is not present anymore. Remove inclusion of this header, its not needed. Signed-off-by: Olaf Hering <olaf@aepfle.de> Committed-by: Jan Beulich <jbeulich@suse.com>
These drivers provide paravirtualised drivers for pre-PVops Linux
kernels which have the classic-Xen patches applied. They do not work
with kernels which are not patched with the classic-Xen patches. In
particular this includes all PVops kernels.
For 2.6.36 and newer you should use the "PVHVM" functionality which is
available in the mainline kernel.
To build do one of:
./mkbuildtree [<arch>]
NB. You can override paths to Xen sources and a (stub) XenLinux
build tree via the XEN and XL environment variable.
- or -
make -C /path/to/kernel/build M=$PWD modules
NB. This is your native kernel build tree (or a distro provided
stub), not the XenLinux sources referred to in step 1.
NB. If you are cross compiling, you need to set ARCH and
CROSS_COMPILE too.
You get four modules, xen-platform-pci.ko, xen-vbd.ko, xen-vnif.ko and
xen-balloon.ko. Load xen-platform-pci first, and then
whichever of xen-vbd, xen-vnif and xen-balloon.ko you happen to need.
