Merge branch 'core-locking-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull core locking changes from Ingo Molnar:
- futex performance increases: larger hashes, smarter wakeups
- mutex debugging improvements
- lots of SMP ordering documentation updates
- introduce the smp_load_acquire(), smp_store_release() primitives.
(There are WIP patches that make use of them - not yet merged)
- lockdep micro-optimizations
- lockdep improvement: better cover IRQ contexts
- liblockdep at last. We'll continue to monitor how useful this is
* 'core-locking-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (34 commits)
futexes: Fix futex_hashsize initialization
arch: Re-sort some Kbuild files to hopefully help avoid some conflicts

+ * Text: "Cryptographic device %x failed and was set offline\n"
+ * Severity: Error
+ * Parameter:
+ * @1: device index
+ * Description:
+ * A cryptographic device failed to process a cryptographic request.
+ * The cryptographic device driver could not correct the error and
+ * set the device offline. The application that issued the
+ * request received an indication that the request has failed.
+ * User action:
+ * Use the lszcrypt command to confirm that the cryptographic
+ * hardware is still configured to your LPAR or z/VM guest virtual
+ * machine. If the device is available to your Linux instance the
+ * command output contains a line that begins with 'card<device index>',
+ * where <device index> is the two-digit decimal number in the message text.
+ * After ensuring that the device is available, use the chzcrypt command to
+ * set it online again.
+ * If the error persists, contact your support organization.

+ help
+ kexec is a system call that implements the ability to shutdown your

+ but it is independent of the system firmware. And like a reboot
+ you can start any kernel with it, not just Linux.
+
+ The name comes from the similarity to the exec system call.
+
+ It is an ongoing process to be certain the hardware in a machine
