2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

2007-02-12[PATCH] mark struct file_operations const 3Arjan van de Ven
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

2007-02-12[PATCH] Char: timers cleanupJiri Slaby
- Use timer macros to set function and data members and to modify expiration time. - Use DEFINE_TIMER for global timers and do not init them at run-time in these cases. - del_timer_sync is common in most cases -- we want to wait for timer function if it's still running.

2007-02-08drm: update core memory manager from git drm treeThomas Hellstrom
Remove the memory manager parameter from the put_block function, as this makes the client code a lot cleaner. Prepare buffer manager for lock and unlock calls. Fix buggy aligned allocations. Remove the stupid root_node field from the core memory manager. Support multi-page buffer offset alignments Add improved alignment functionality to the core memory manager. This makes an allocated block actually align itself and returns any wasted space to the manager. Signed-off-by: Dave Airlie <airlied@linux.ie>

In i915_vblank_pipe_set(), only update dev_priv->vblank_pipe and call i915_enable_interrupt() if the argument passed from userspace is valid to avoid corrupting dev_priv->vblank_pipe on invalid arguments.

of pipe number. Handle relative as well as absolute target sequence numbers. Return error if target sequence has already passed, so userspace can deal with this situation as it sees fit. On success, return the sequence number of the vertical blank when the buffer swap is expected to take place.
