This move to define those symbol before including linux/mm.h seems to make the
drill:

But next compile error appears there:

In file included from
/CAD/linux-2.6.25-rc1-pa-git-20080212/arch/parisc/mm/init.c:26:
include2/asm/pgalloc.h:142: error: conflicting types for 'pte_free_kernel'
include2/asm/pgalloc.h:137: error: previous definition of 'pte_free_kernel'
was here
include2/asm/pgalloc.h: In function 'pte_free_kernel':
include2/asm/pgalloc.h:144: error: expected ')' before ';' token

make[2]: *** [arch/parisc/mm/init.o] Error 1
make[1]: *** [arch/parisc/mm] Error 2
make: *** [sub-make] Error 2


and in include/asm-parisc/pgalloc.h we can read:

static inline void pte_free_kernel(struct mm_struct *mm, pte_t *pte)
{
        free_page((unsigned long)pte);
}

static inline void pte_free_kernel(struct mm_struct *mm, struct page *pte)
{
        pgtable_page_dtor(pte);
        pte_free_kernel(page_address((pte));
}

i.e. 2 time the definition of the same function: which is the right definition?

Cheers,
    r.
