x86: fix "__udivdi3" [drivers/scsi/aha1542.ko] undefined
Commit 976e8f677e42757e5586ea04a9ac8bb8ddaa037e ("x86: asm/io.h: unify virt_to_phys/phys_to_virt") changed the return of virt_to_phys from long to phys_addr_t which is unsigned long long on a PAE platform. So, I could suggest a fix below since isa addresses may never be above 32 bits. Signed-off-by: Ingo Molnar <mingo@elte.hu>
