From bf33a70a73876b163d62612e9567cbac6604ba7e Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Fri, 13 Feb 2009 12:52:44 -0600 Subject: [PATCH] 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.
