Pull x86 bootup changes from Ingo Molnar:
 "Deal with bootloaders which fail to initialize unknown fields in
  boot_params to zero, by sanitizing boot params passed in.

  This unbreaks versions of kexec-utils.  Other bootloaders do not
  appear to show sensitivity to this change, but it's a possibility for
  breakage nevertheless."

* 'x86-boot-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86, boot: Sanitize boot_params if not zeroed on creation

+Snapshot
+--------
+CONFIG_TRACER_SNAPSHOT makes a generic snapshot feature
+available to all non latency tracers. (Latency tracers which
+record max latency, such as "irqsoff" or "wakeup", can't use
+this feature, since those are already using the snapshot
+mechanism internally.)
+
+Snapshot preserves a current trace buffer at a particular point
+in time without stopping tracing. Ftrace swaps the current
+buffer with a spare buffer, and tracing continues in the new
+current (=previous spare) buffer.
+
+The following debugfs files in "tracing" are related to this
+feature:
+
+  snapshot:
+
+       This is used to take a snapshot and to read the output
+       of the snapshot. Echo 1 into this file to allocate a
+       spare buffer and to take a snapshot (swap), then read
+       the snapshot from this file in the same format as
+       "trace" (described above in the section "The File
+       System"). Both reads snapshot and tracing are executable
+       in parallel. When the spare buffer is allocated, echoing
+       0 frees it, and echoing else (positive) values clear the
