problem compiling current pvops xen/master on x86

[Christian Tramnitz]

Hi,

I have been running my systems on 2.6.29-xen-r4 (based on Andrew Lyon's 
ebuild) for some time but with Xen 4.0.0 around the corner I wanted to 
give the latest pvops a quick glance.

However I'm not even able to compile it:

   CC      arch/x86/kernel/acpi/boot.o
In file included from arch/x86/kernel/acpi/boot.c:45:
/usr/src/linux-pvops/arch/x86/include/asm/xen/pci.h:37: error: expected 
declaration specifiers or '...' before 'domid_t'
make[3]: *** [arch/x86/kernel/acpi/boot.o] Error 1
make[2]: *** [arch/x86/kernel/acpi] Error 2
make[1]: *** [arch/x86/kernel] Error 2
make: *** [arch/x86] Error 2

This build was meant for a x86 domU (dom0 support is disabled), I have 
nothing special in my kernel config (basically created with make 
oldconfig from my running config), maybe except for pcifront support 
(which is primary reason for not using a vanilla linux kernel).


Any ideas?


Best regards,
    Christian

Yeah, I've a patch for that in the my tree and as well to get the pv-ops kernel
to compile on PPC and IA64 (and MIPS/StrongARM).

The solutions for the most part are unfortunatly hacks.

Here is the git tree:
git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git rpm-draft-3

I am going to ask Jeremy to pull in a patch for that specific issue in
his tree.
