Re: [Fedora-ia64-list] Re: Four ways RH could help with xen-ia64

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)

Best Regards,

Akio Takebe
