mm: make FIRST_USER_ADDRESS unsigned long on all archs

2015-02-12T01:06:03+00:00

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.

nios2: drop _PAGE_FILE and pte_file()-related helpers

2015-02-10T22:30:32+00:00

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

nios2: Remove unused prepare_to_copy()

2015-02-09T06:17:27+00:00

prepare_to_copy() was removed from all architectures supported at that
time in commit 55ccf3fe3f9a ("fork: move the real prepare_to_copy()
users to arch_dup_task_struct()"). Remove it from nios2 as well.

nios2/uaccess: fix sparse errors

2014-12-17T05:53:41+00:00

virtio wants to read bitwise types from userspace using get_user.  At the
moment this triggers sparse errors, since the value is passed through an
integer.

Fix that up using __force.
