      drm/radeon: Add probing of clocks from device-tree · 7b044f40
      Benjamin Herrenschmidt authored 
      When we find no ROM we understand and a device-tree is present, see
if we can retreive clock info from there.

      drm/radeon: drop old and broken mesa warning · b494d5d4
      Dave Airlie authored 
      This never really got fixed in mesa, and the kernel deals with the problem
just fine, so don't got reporting things that confuse people.

      drm/radeon: Fix pci_map_page() error checking · a30f6fb7
      Benjamin Herrenschmidt authored 
      0 is a valid DMA address from pci_map_page(), use pci_dma_mapping_error()
instead to check for errors

[airlied: fix warning + two other places with errors.]

      drm: Remove count_lock for calling lastclose() after 58474713 (v2) · 1a72d65d
      Chris Wilson authored 
      When removing of the BKL the locking around lastclose() was rearranged
and resulted in the holding of the open_count spinlock over the call
into drm_lastclose(). The drivers were not ready for this path to be
atomic - it may indeed involve long waits to release old objects and
cleanup the GPU - and so we ended up scheduling whilst atomic.

v2: The spinlock is actually superfluous as access to open_count is
entirely serialised by drm_global_mutex and so can be dropped. The
count_lock spinlock instead appears to be used to protect access to
dev->buf_alloc and dev->buf_use.

      DRM: Replace kmalloc/memset combos with kzalloc · 94e3370e
      Davidlohr Bueso authored 
      Currently most, if not all, memory allocation in drm_bufs.c is followed by initializing the memory with 0.

Replace the use of kmalloc+memset with kzalloc.
