[IA64] Module gp must point to valid memory
Some bits of the kernel assume that gp always points to valid memory, in particular PHYSICAL_MODE_ENTER() assumes that both gp and sp are valid virtual addresses with associated physical pages. The IA64 module loader puts gp well past the end of the module, with no physical backing. Offsets on gp are still valid, but physical mode addressing breaks for modules. Ensure that gp always falls within the module body. Also ensure that gp is 8 byte aligned. Signed-off-by: Keith Owens <kaos@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
