Merge branch 'perf/core' into perf/uprobes
Merge in latest upstream (and the latest perf development tree), to prepare for tooling changes, and also to pick up v3.4 MM changes that the uprobes code needs to take care of. Signed-off-by: Ingo Molnar <mingo@kernel.org>

- * Hosts that support power saving can use the 'enable' and 'disable'
- * methods to exit and enter power saving states. 'enable' is called
- * when the host is claimed and 'disable' is called (or scheduled with
- * a delay) when the host is released. The 'disable' is scheduled if
- * the disable delay set by 'mmc_set_disable_delay()' is non-zero,
- * otherwise 'disable' is called immediately. 'disable' may be
- * scheduled repeatedly, to permit ever greater power saving at the
- * expense of ever greater latency to re-enable. Rescheduling is
- * determined by the return value of the 'disable' method. A positive
- * value gives the delay in milliseconds.
- *
- * In the case where a host function (like set_ios) may be called
- * with or without the host claimed, enabling and disabling can be
- * done directly and will nest correctly. Call 'mmc_host_enable()' and
- * 'mmc_host_lazy_disable()' for this purpose, but note that these
- * functions must be paired.
- *
- * Alternatively, 'mmc_host_enable()' may be paired with
- * 'mmc_host_disable()' which calls 'disable' immediately. In this
- * case the 'disable' method will be called with 'lazy' set to 0.
- * This is mainly useful for error paths.
- *
- * Because lazy disable may be called from a work queue, the 'disable'
- * method must claim the host when 'lazy' != 0, which will work
- * correctly because recursion is detected and handled.
+ * 'enable' is called when the host is claimed and 'disable' is called
+ * when the host is released. 'enable' and 'disable' are deprecated.
