Eliminate the copy of i2c_bus in sdvo_priv. Eliminate local copies of i2c_bus and ddcbus. Eliminate unused settings of slave_addr. Signed-off-by: Keith Packard <keithp@keithp.com>

Keith Packard authored
The existing API passed around intel_i2c_chan pointers, which are dependent on the i2c bit-banging algo. This precluded the driver from using outputs which use a different algo. Switching to the more general i2c_adpater allows the driver to support non bit-banging DDC. This also required moving the slave address into the output private structures.

The fence register value also depends upon the stride of the object, so we need to clear the fence if that is changed as well. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> [anholt: Added 8xx and 965 paths, and renamed the confusing i915_gem_object_tiling_ok function to i915_gem_object_fence_offset_ok] Signed-off-by: Eric Anholt <eric@anholt.net>

Chris Wilson authored
With the work by Jesse Barnes to eliminate allocation of fences during execbuffer, it becomes possible to write to the scan-out buffer with it never acquiring a fence (simply by only ever writing to the object using tiled GPU commands and never writing to it via the GTT). So for pre-i965 chipsets which require fenced access for tiled scan-out buffers, we need to obtain a fence register.

After performing an operation over the page list for a buffer retrieved by i915_gem_object_get_pages() the pages need to be returned with i915_gem_object_put_pages(). This was not being observed for the phys objects which were thus leaking references to their backing pages.

While sifting through the inteldrmfb code trying to solve #22040 I found that the fb restore path doesn't check the return value of drm_crtc_helper_set_config(), which seems to have all sorts of potential failure modes. We should warn someone if one of these is triggered.

Kmemleak allocates memory for pointer tracking and it tries to avoid using GFP_ATOMIC if the caller doesn't require it. However other gfp flags may be passed by the caller which aren't required by kmemleak. This patch filters the gfp flags so that only GFP_KERNEL | GFP_ATOMIC are used.

As part of adding hugetlbfs support for MIPS, I am adding a new kconfig variable 'SYS_SUPPORTS_HUGETLBFS'. Since some mips cpu varients don't yet support it, we can enable selection of HUGETLBFS on a system by system basis from the arch/mips/Kconfig.

The TLB handlers need to check for huge pages and give them special handling. Huge pages consist of two contiguous sub-pages of physical memory. * Loading entrylo0 and entrylo1 need to be handled specially. * The page mask must be set for huge pages and then restored after writing the TLB entries. * The PTE for huge pages resides in the PMD, we halt traversal of the tables there.

These SOCs are multi-core mips64 processors with existing support over in arch/mips. The driver files can be categorized into three basic groups: 1) Register definitions, these are named cvmx-*-defs.h 2) Main driver code, these have names that don't start cvmx-. 3) Interface specific functions and other utility code, names starting with cvmx- Signed-off-by: David Daney <ddaney@caviumnetworks.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
