Re: _gp_disp

["Bradley D. LaRonde" <brad@ltc.com>]

If you are building your module as part of kernel (make modules) that should
take care of the flags.

You might be seeing a binutil issue.  I think loadable modules were broken
until the trad[big|little]mips emulations.  What version of binutils are you
using?

Brad
