ext4: fix potential deadlock with setuid files and EXT4_IOC_MOVE_EXT
file_remove_suid() must be called with i_mutex down, since it calls
notify_change(). In addition, we really want to remove the suid file
*before* we modify the donor file, to avoid someone from trying to
exploit a race.

drm: Add drm_format_num_planes() utility function
This function returns the number of planes used by a specific pixel
format.

drm: call connector dpms fxn, when setting config
Call connector->funcs->dpms(DPMS_ON) rather than just setting
connector->dpms = DPMS_ON. This ensures that if the connector
has something to do to enable the output (rather than just using
drm_helper_connector_dpms helper directly), that this happens
at bootup. This solves an issue with connectors not getting
enabled from fbcon_init() when the driver is loaded.

drm/radeon/kms: don't use 0 bpc for adjusting hdmi clock
If the bpc is set from the connector is 0, we then use it later to adjust
in a special case the HDMI pixel clock, however if the bpc is 0, we end up
passing a 0 pixel clock into the code.
I'm not sure if this is the correct answer or if we should avoid the HDMI
clock adjustment for 0 values.
This fixes a divide by 0 on my Llano system with a HDMI monitor and hdmi
audio enabled.

drm/radeon: introduce a sub allocator and convert ib pool to it v4
Somewhat specializaed sub-allocator designed to perform sub-allocation
for command buffer not only for current cs ioctl but for future command
submission ioctl as well. Patch also convert current ib pool to use
the sub allocator. Idea is that ib poll buffer can be share with other
command buffer submission not having 64K granularity.
v2 Harmonize pool handling and add suspend/resume callback to pin/unpin
sa bo (tested on rv280, rv370, r420, rv515, rv610, rv710, redwood, cayman,
rs480, rs690, rs880)
v3 Simplify allocator
v4 Fix radeon_ib_get error path to properly free fence
