While at it, care to send a patch that defined an empty
flush_fp_to_thread() in the header instead ?
ie, switch_to.h
#ifdef CONFIG_PPC_FPU
extern void flush_fp_to_thread(struct task-struct *);
#else
static inline void flush_fp_to_thread(struct task-struct *) { };
#endif
And get rid of the ifdef's here (and elsewhere if any) ?
Thanks !
Cheers,
Ben.
