agp: kill agp_flush_chipset and corresponding ioctl

2010-11-23T20:14:45Z

The intel drm calls the chipset functions now directly. Userspace never called the corresponding ioctl, hence it can be killed, too. Cc: Dave Airlie Signed-off-by: Daniel Vetter Signed-off-by: Chris Wilson

BKL: remove extraneous #include

2010-11-17T16:59:32Z

The big kernel lock has been removed from all these files at some point, leaving only the #include. Remove this too as a cleanup. Signed-off-by: Arnd Bergmann Signed-off-by: Linus Torvalds

agp: Remove the BKL from agp_open

2009-10-14T15:36:54Z

- Remove the BKL from agp_open - Perform a few clean-ups. Analysis: --------- int minor is local to the function. The following are protected by agp_fe.agp_mutex struct agp_file_private *priv; struct agp_client *client; Call-outs: kzalloc should be safe to call under the mutex_lock agp_find_client_by_pid: - agp_mmap calls that under agp_fe.agp_mutex which we hold in agp_open - agpioc_reserve_wrap calls it without any locking what-so-ever. - Is that an error? Or is that okay because it has pid that is a unique handle? agp_insert_file_private: - This function only manipulates struct agp_file_private, once again while agp_fe.agp_mutex is held Signed-off-by: John Kacur Acked-by: David Airlie LKML-Reference: Signed-off-by: Thomas Gleixner

agp: convert drivers/char/agp/frontend.c to use unlocked_ioctl

2008-04-26T08:43:20Z

As of now, agp_compat_ioctl already runs without the BKL. Mutual exclusion is enforced by agp_fe.agp_mutex in agp_ioctl() and agp_compat_ioctl(). Apply the same locking rationale to the two functions allowing BKL cleanup. Signed-off-by: Mathieu Segaud Signed-off-by: Andrew Morton Signed-off-by: Dave Airlie

agp: remove uid comparison as security check

2008-02-05T04:33:32Z

In the face of containers and user namespaces, a uid==0 check for security is not safe. Switch to a capability check. I'm not sure I picked the right capability, but this being AGP CAP_SYS_RAWIO seemed to make sense. Signed-off-by: Serge Hallyn Signed-off-by: Dave Airlie

agp: add chipset flushing support to AGP interface

2008-02-05T04:33:32Z

This bumps the AGP interface to 0.103. Certain Intel chipsets contains a global write buffer, and this can require flushing from the drm or X.org to make sure all data has hit RAM before initiating a GPU transfer, due to a lack of coherency with the integrated graphics device and this buffer. This just adds generic support to the AGP interfaces, a follow-on patch will add support to the Intel driver to use this interface. Signed-off-by: Dave Airlie

Remove fs.h from mm.h

2007-07-30T00:09:29Z

Remove fs.h from mm.h. For this, 1) Uninline vma_wants_writenotify(). It's pretty huge anyway. 2) Add back fs.h or less bloated headers (err.h) to files that need it. As result, on x86_64 allyesconfig, fs.h dependencies cut down from 3929 files rebuilt down to 3444 (-12.3%).
