Runtime suspend and runtime resume are modified in order to
reduce the complexity and improve the usability of runtime pm.
After probe function, s3c-fb driver is not suspended until
suspend or remove is called.The scheme is changed as follows:
runtime_get is only called in probe and resume.
runtime_put is only called in remove and suspend.
open/close cannot call the runtime_get/put.Also, runtime_susepnd/resume are just called by runtime pm,
not doing suspend/resume routine any longer. This is because
open/close cannot call the runtime_get/put; the suspend/resume
routine in runtime_suspend/resume were previously used when
open and close were called.The name of s3c-fb dev_pm_ops is changed from s3cfb_pm_ops to
s3c_fb_pm_ops in order to use more consistent naming.Signed-off-by: Jingoo Han

The Freescale DIU driver allocates multiple blocks of memory, including
multiple DMA buffers. Merge all of these blocks into one data structure.Specifically:
1) struct fsl_diu_data now contains everything that needs to be allocated,
except for the framebuffers themselves. DMA'able objects are aligned correctly
within the structure.2) struct diu_addr is no longer needed, because we don't have to manage
multiple blocks of DMA memory.3) Since there's no diu_addr any more, macro DMA_ADDR is used to calculate
the DMA address of any field in fsl_diu_data.4) Functions allocate_buf() and free_buf() are no longer needed, because we
now assume that dma_alloc_coherent() will allocate a page-aligned block,
and everything is properly aligned with fsl_diu_data already, so we no longer
need to align any memory blocks ourselves.5) The "dummy" area descriptor is now defined separately from the other
five ADs, so NUM_AOIS (previously called FSL_AOI_NUM) is now set to five
instead of six. Previously, all six were combined together to avoid a
separate call to allocate_buf() just for the dummy AD.6) framebuffer_alloc() and framebuffer_release() are no longer used. The
framebuffer is initialized manually.7) Error handling is simplified since there's only one memory buffer
allocated.Signed-off-by: Timur Tabi

This reverts commit eb1711bb94991e93669c5a1b5f84f11be2d51ea1.
It blows up the i915 seqno tracking, resulting in the
BUG_ON(seqno == 0);
in i915_wait_request() triggering, which will cause lock-ups.

This adds a default setting for semaphores parameter, and enables
semaphores by default on IVB.For now, as semaphores interaction with VTd causes random issues on
SNB, we do not enable them by default. But they can still be enabled
via the semaphores=1 kernel parameter.v2: enables semaphores on SNB when IO remapping is disabled, with base

We were checking whether the supplied edid matched the connector it was
read from. We do this in case a DDC read returns an EDID for another
device on a multifunction or otherwise interesting card. However, we

This prevents an in-kernel division by zero which happens when we are
asking for i915_chipset_val too quickly, or within a race condition
between the power monitoring thread and userspace accesses via debugfs.The issue can be reproduced easily via the following command:
while ``; do cat /sys/kernel/debug/dri/0/i915_emon_status; doneThis is particularly dangerous because it can be triggered by
a non-privileged user by just reading the debugfs entry.This issue was also found independently by Konstantin Belousov
, who proposed a similar patch.Reported-by: Konstantin Belousov
