[Patch] "Helper" for dom0/domU Kernels

[Patch] "Helper" for dom0/domU Kernels

[Robert Valentan]

[-- Attachment #1: Type: text/plain, Size: 252 bytes --]

This patch add's a XEN_SPLIT_KERNEL to Config.mk and use it
in config/Linux.mk
This patch is also needed for my vnet-patch (some minutes before)
to get the kernel_src dir.

Can't you just do some grep hack on the KERNELS variable in the vnet
Makefile? I think it's enough that KERNELS can be overridden -- we don't
need yet another top-level config option.
