Subject: [PATCH] moduleparam: fix alpha and ia64 compile failures

On alpha and ia64 only relocations to local data can go into read-only
sections. The vast majority of module parameters use the global generic
param_set_*/param_get_* functions, so the 'const' attribute for struct
kernel_param is not only useless, but it also causes compile failures due
to 'section type conflict' in those rare cases where param_set/get are
local functions.

This fixes
