drm: remove unnecessary fault wrappers

2017-02-25T01:46:55+00:00

The fault wrappers drm_vm_fault(), drm_vm_shm_fault(), drm_vm_dma_fault() and drm_vm_sg_fault() used to provide extra logic beyond what was in the "drm_do_*" versions of these functions, but as of commit ca0b07d9a969 ("drm: convert drm from nopage to fault") they are just unnecessary wrappers that do nothing. Remove them, and rename the the drm_do_* fault handlers to remove the "do_" since they no longer have corresponding wrappers.

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

2017-02-25T01:46:54+00:00

->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.

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

2016-12-15T00:04:09+00:00

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.

drm: Nuke legacy maps debugfs files

2016-06-16T08:16:11+00:00

GEM stopped using those a while ago, and no one should ever need to use them again to debug legacy horror show drivers. Nuke it all. Aside: It would kinda be nice if we'd have some generic debugfs dumps for at least kms ...

drm: Remove __OS_HAS_AGP

2015-09-30T08:44:48+00:00

We already express the drm/agp depencies correctly in Kconfig, so we can rip this remnant from the shared drm core days. Aside: Pretty much all the #ifdefs in radeon/nouveau could be killed if ttm would provide dummy functions. I'm not going to volunteer for that though. v2: Use IS_ENABLED(CONFIG_AGP) as suggested by Ville v3: Polish from Ville's review.

Now that we've removed the copypasted users in gem/ttm we can relegate the legacy buffer mapping support to where it belongs. Also give it the proper drm_legacy_ prefix. While at it statify drm_mmap_locked, somehow I've missed that in my previous header rework. Signed-off-by: Daniel Vetter Reviewed-by: David Herrmann Acked-by: Alex Deucher Signed-off-by: Dave Airlie
