d016bf7ece mm: make FIRST_USER_ADDRESS unsigned long on all archs 
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':
 >> mm/mmap.c:2857:2: warning: right shift count >= width of type [enabled by default]

The code:

 > 2857                WARN_ON(mm_nr_pmds(mm) >
   2858                                round_up(FIRST_USER_ADDRESS, PUD_SIZE) >> 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.

b007ea798f arm: drop L_PTE_FILE and pte_file()-related helpers 
We've replaced remap_file_pages(2) implementation with emulation.  Nobody
creates non-linear mapping anymore.

This patch also adjust __SWP_TYPE_SHIFT, effectively increase size of
possible swap file to 128G.

03ff3efb64 Remove remaining bits of io_remap_page_range() 
Commit 33bf56106d ("feature removal of io_remap_page_range()") removed
io_remap_page_range(), but it is still included in some arch header
files.  It has no in-tree users.

a91ed072d6 ARM: 5988/1: pgprot_dmacoherent() for non-mmu builds 
Commit 26a26d3296 ("dma-mapping: switch
ARMv7 DMA mappings to retain 'memory' attribute") added a new macro,
pgprot_dmacoherent(), to correctly map DMA memory. The non-mmu pgtable
support code also needs to implement this macro, otherwise when
compiling you get:

  CC      arch/arm/mm/dma-mapping.o
arch/arm/mm/dma-mapping.c: In function 'dma_alloc_coherent':
arch/arm/mm/dma-mapping.c:320: error: implicit declaration of function 'pgprot_dmacoherent'
