Sergei Trofimovich a25fb8508c 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 9c184a073b ("[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.
