Hi, Juan, Aron and all
I fix Juan's http://hg.et.redhat.com/kernel/linux-2.6-xen-fedora
to build on ia64.
But I have not booted linux kernel (not xen),
and there are many compile warnings.
I'm fixing the tree now.
I used the attach config.
Please check them.
My fix patcheds are the blew. Please comments.
1. build_ia64_add_files.patch
simple import gate.S, gate.ld.S, patch.c into arch/ia64/kernel
(these are from linux-2.6.18-rc2)
2. build_ia64.patch
some fix (resend_irq, ioremap, and so on)
Signed-off-by: Akio Takebe <takebe_akio@xxxxxxxxxxxxxx>
Best Regards,
Akio Takebe
