[Bug 151327] Re: [Gutsy] binary graphics drivers don't load with linux-image-2.6.22-14-xen

[Omar Benhamid]

Hi all, I found a problem with xenified kernel source in 
arch/i386/mm/hypervisor.c and arch/x86_64/kernel/smp-xen.c : 
xen_l1_entry_update and flush_tlb_page are not exported to kernel symbol table. 
I exported the symbols  and the module loads (well causing some trouble on my 
machine ...). 
Sorry i'm not very familiar with debian bulid system to give the right things 
but here is the diff I applied to debian/build/custom-source-xen in linux 
kernel source :
