If an architecture uses 4level-fixup.h we don't need to do anything as
it includes 5level-fixup.h.

If an architecture uses pgtable-nop*d.h, define __ARCH_USE_5LEVEL_HACK
before inclusion of the header. It makes asm-generic code to use
5level-fixup.h.

If an architecture has 4-level paging or folds levels on its own,
include 5level-fixup.h directly.

The core has developed a need for a "pfn_t" type [1].  Convert the usage
of pfn_t by usermode-linux to an unsigned long, and update pfn_to_phys()
to drop its expectation of a typed pfn.

<title>mm: make FIRST_USER_ADDRESS unsigned long on all archs</title>

LKP has triggered a compiler warning after my recent patch "mm: account
pmd page tables to the process":

    mm/mmap.c: In function 'exit_mmap':
 &gt;&gt; mm/mmap.c:2857:2: warning: right shift count &gt;= width of type [enabled by default]

The code:

 &gt; 2857                WARN_ON(mm_nr_pmds(mm) &gt;
   2858                                round_up(FIRST_USER_ADDRESS, PUD_SIZE) &gt;&gt; PUD_SHIFT);

In this, on tile, we have FIRST_USER_ADDRESS defined as 0.  round_up() has
the same type -- int.  PUD_SHIFT.

I think the best way to fix it is to define FIRST_USER_ADDRESS as unsigned
long.  On every arch for consistency.

We've replaced remap_file_pages(2) implementation with emulation.  Nobody
creates non-linear mapping anymore.

<title>um, x86: Cast to (u64 *) inside set_64bit()</title>

After tightening up the types passed to set_64bit(), the cast to
(phys_t *) triggers a warning apparently because phys_t is defined as
"unsigned long" when building on 64 bits; however, u64 is defined as
"unsigned long long".  This is, however, a explicit cast inside a
size-specific call, so just make the cast explicitly (u64 *).
