Re: [Xen-merge] CONFIG_XEN (and more?)

Perhaps the CONFIG_X86_XEN designation should start appearing

changes into the -sparse trees at some point and it
doesn't require any patches outside of arch/ia64, asm-ia64,
and of course the xen common directories (drivers/xen, etc).

If the Xen/x86-required changes to linux common files
(include/linux/highmem.h for example) are ifdef'd,
then other architectures can use the same mkbuildtree.

None of the common code changes are CONFIG_XEN'ed, and they are designed not to break compilation of any other architecture. So xen/ia64 should integrate with them just fine with no modification required.

There is no CONFIG_X86_XEN, because there has not so far been any need for it.
