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.
