ia64: fix module loading for gcc-5.4
Starting from gcc-5.4+ gcc generates MLX instructions in more cases to refer local symbols: https://gcc.gnu.org/PR60465 That caused ia64 module loader to choke on such instructions: fuse: invalid slot number 1 for IMM64 The Linux kernel used to handle only case where relocation pointed to slot=2 instruction in the bundle. That limitation was fixed in linux by commit 9c184a073bfd ("[IA64] Fix 2.6 kernel for the new ia64 assembler") See http://sources.redhat.com/bugzilla/show_bug.cgi?id=1433 This change lifts the slot=2 restriction from the kernel module loader. Tested on 'fuse' and 'btrfs' kernel modules.
