android: unconditionally remove callbacks in sync_fence_free()

2015-12-21T21:37:53Z

Using fence->status to determine whether or not there are callbacks remaining on the sync_fence is racy since fence->status may have been decremented to 0 on another CPU before fence_check_cb_func() has completed. By unconditionally calling fence_remove_callback() for each fence in the sync_fence, we guarantee that each callback has either completed (since fence_remove_callback() grabs the fence lock) or been removed.

Revert "scatterlist: use sg_phys()"

2015-12-15T20:54:06Z

commit db0fa0cb0157 "scatterlist: use sg_phys()" did replacements of the form: phys_addr_t phys = page_to_phys(sg_page(s)); phys_addr_t phys = sg_phys(s) & PAGE_MASK; However, this breaks platforms where sizeof(phys_addr_t) > sizeof(unsigned long). Revert for 4.3 and 4.4 to make room for a combined helper in 4.5.
