drm/armada: Replace drm_gem_object_reference/unreference() with _get/put()

2017-10-16T19:01:51Z

This patch replace instances of drm_gem_object_reference/unreference with *_get/put() suffixes, because get/put is shorter and consistent with the kernel use of *_get/put() suffixes. This was done with the following Coccinelle script: @r1@ expression e; @@ ( -drm_gem_object_reference(e); +drm_gem_object_get(e); | -drm_gem_object_unreference(e); +drm_gem_object_put(e); | -drm_gem_object_unreference_unlocked(e); +drm_gem_object_put_unlocked(e); ) Signed-off-by: Haneen Mohammed [resolved small conflict with removed armada_gem_dumb_map_offset] Signed-off-by: Sean Paul Link: https://patchwork.freedesktop.org/patch/msgid/a59ef1ed109ade897bcffcb01b33214262db8942.1505932812.git.hamohammed.sa@gmail.com

drm/armada: Use .dumb_map_offset and .dumb_destroy defaults

2017-09-02T12:22:20Z

This driver can use the drm_driver.dumb_destroy and drm_driver.dumb_map_offset defaults, so no need to set them. Cc: Russell King Signed-off-by: Noralf Trønnes Reviewed-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/1502986891-36764-3-git-send-email-noralf@tronnes.org

drm/armada: don't abuse DMA_ERROR_CODE

2017-06-20T09:12:58Z

dev_addr isn't even a dma_addr_t, and DMA_ERROR_CODE has never been a valid driver API. Add a bool mapped flag instead. Signed-off-by: Christoph Hellwig

dma-buf: Rename dma-ops to prevent conflict with kunmap_atomic macro

2017-04-20T08:17:46Z

Seeing the kunmap_atomic dma_buf_ops share the same name with a macro in highmem.h, the former can be aliased if any dma-buf user includes that header. I'm personally trying to include highmem.h inside scatterlist.h and this breaks the dma-buf code proper. Christoph Hellwig suggested [1] renaming it and pushing this patch ASAP. To maintain consistency I've renamed all four of kmap* and kunmap* to be map* and unmap*. (Even though only kmap_atomic presently conflicts.)

mm, fs: reduce fault, page_mkwrite, and pfn_mkwrite to take only vmf

2017-02-25T01:46:54Z

->fault(), ->page_mkwrite(), and ->pfn_mkwrite() calls do not need to take a vma and vmf parameter when the vma already resides in vmf. Remove the vma parameter to simplify things.

drm: Improve drm_mm search (and fix topdown allocation) with rbtrees

2017-02-03T10:10:32Z

The drm_mm range manager claimed to support top-down insertion, but it was neither searching for the top-most hole that could fit the allocation request nor fitting the request to the hole correctly. In order to search the range efficiently, we create a secondary index for the holes using either their size or their address. This index allows us to find the smallest hole or the hole at the bottom or top of the range efficiently, whilst keeping the hole stack to rapidly service evictions. v2: Search for holes both high and low. Rename flags to mode. v3: Discover rb_entry_safe() and use it! v4: Kerneldoc for enum drm_mm_insert_mode.

mm: use vmf->address instead of of vmf->virtual_address

2016-12-15T00:04:09Z

Every single user of vmf->virtual_address typed that entry to unsigned long before doing anything with it so the type of virtual_address does not really provide us any additional safety. Just use masked vmf->address which already has the appropriate type. Link: http://lkml.kernel.org/r/1479460644-25076-3-git-send-email-jack@suse.cz Signed-off-by: Jan Kara Acked-by: Kirill A.
