mm/filemap_xip.c compilation failure

[Geert Uytterhoeven]

	Hi Carsten,

While cross-compiling a kernel for m68k, I stumbled across this
compilation error:

| mm/filemap_xip.c: In function `__xip_unmap':
| mm/filemap_xip.c:194: request for member `pte' in something not a structure or union

Apparently pte_pfn() takes a pte_t, not a pointer to a pte_t. From
looking at asm/page.h, it seems to be the same on ia32 or ppc (iff
STRICT_MM_TYPECHECKS is enabled, which is disabled by default on ppc).

Disclaimer: the patch below is untested, except for a compile test.
