Ideas on removing a compiler warning in 'init_task.c' ...

[Steven J. Hill]

I am trying to clean up a few compiler warnings. Here is one remaining
one:

   CC      arch/mips/kernel/init_task.o
   arch/mips/kernel/init_task.c:15: warning: initialization makes integer from 
pointer without a cast

which has to do with this line:

   static struct sighand_struct init_sighand = INIT_SIGHAND(init_sighand);

I actually broke out the macro and it is complaining about the initialization
of 'action' member in the 'sighand_struct' defined in 'include/linux/sched.h'.

   struct sighand_struct {
           atomic_t                count;
           struct k_sigaction      action[_NSIG];
           spinlock_t              siglock;
   };

I do not see this when compiling x86 code and the MIPS structure is
not that drastically different IMHO. Anyone have some ideas on this
one?

The members of struct sigaction are ordered differently on MIPS.
