I have backport this patch to mesa 10.4.0 and fixed. but i'm not sure the
changes in radeon_winsys_bo_from_ptr isn't ok? because buffer_from_ptr missing
in mesa 10.4.0. Thanks!

GPU pages are 4k.  These functions are dealing with the GPU's virtual address
space, not the CPU's.  What sort of problem are you seeing?

Bug ID: 92738
   Summary: Randon R7 240 doesn't work on 16KiB page size platform
   Product: Mesa
   Version: git
  Hardware: Other
OS: Linux (All)
Status: NEW
  Severity: normal
  Priority: medium
 Component: Drivers/Gallium/r600
  Assignee: dri-devel at lists.freedesktop.org
  Reporter: r at hev.cc
QA Contact: dri-devel at lists.freedesktop.org

The radeon gpu that with VM supported doesn't work on >= 4KiB page size
platforms. (e.g. Loongson 16k)

It seems we assume that the maximum page size is 4096 in radeon_bomgr_find_va
and radeon_bomgr_free_va. I think dynmamic get system page size here would
better.
