Hmm ... so it might be a SMP kernel problem?

I think __flush_icache_page should go away.  Here is a patch.
http://www.linux-mips.org/archives/linux-mips/2006-09/msg00003.html

BTW, what you tried is something like this ?

include/asm-mips/cacheflush.h:
static inline void flush_icache_page(struct vm_area_struct *vma,
        struct page *page)
{
        __flush_icache_page(vma, page);
}

If this caused panic, what is the message?
