Merge commit 'perf/core' into perf/hw-breakpoint
Conflicts: kernel/Makefile kernel/trace/Makefile kernel/trace/trace.h samples/Makefile Merge reason: We need to be uptodate with the perf events development branch because we plan to rewrite the breakpoints API on top of perf events.

every uevent.
+config DEVTMPFS
+ bool "Create a kernel maintained /dev tmpfs (EXPERIMENTAL)"
+ depends on HOTPLUG && SHMEM && TMPFS
+ help
+ This creates a tmpfs filesystem, and mounts it at bootup
+ and mounts it at /dev. The kernel driver core creates device
+ nodes for all registered devices in that filesystem. All device
+ nodes are owned by root and have the default mode of 0600.
+ Userspace can add and delete the nodes as needed. This is
+ intended to simplify bootup, and make it possible to delay
+ the initial coldplug at bootup done by udev in userspace.
+ It should also provide a simpler way for rescue systems
+ to bring up a kernel with dynamic major/minor numbers.
+ Meaningful symlinks, permissions and device ownership must
+ still be handled by userspace.
+ If unsure, say N here.

+config DEVTMPFS_MOUNT
+ bool "Automount devtmpfs at /dev"
+ depends on DEVTMPFS
+ help
+ This will mount devtmpfs at /dev if the kernel mounts the root
+ filesystem. It will not affect initramfs based mounting.
+ If unsure, say N here.
