This annotates NMI functions with notrace. Some tracers may be able to live with this, but some cannot. The safest is to turn it off, it's not particularly interesting anyway.

All kobjects require a dynamically allocated name now. We no longer need to keep track if the name is statically assigned, we can just unconditionally free() all kobject names on cleanup. Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Our automated test suite looks for keywords like error, fail, warning in the boot log. In the case when the nmi watchdog is determined to be stuck in check_nmi_watchdog(), none of those keywords are displayed. This patch adds a keyword, "WARNING:", so it makes it easier to notice when the nmi watchdog isn't working correctly. Also add a proper KERN_WARNING mark to this printout.

Since the x86 merge, lots of files that referenced their own filenames are no longer correct. Rather than keep them up to date, just delete them, as they add no real value. Additionally: - fix up comment formatting in scx200_32.c - Remove a credit from myself in setup_64.c from a time when we had no SCM - remove longwinded history from tsc_32.c which can be figured out from git.

The clock events merge introduced a change to the nmi watchdog code to handle the not longer increasing local apic timer count in the broadcast mode. This is fine for UP, but on SMP it pampers over a stuck CPU which is not handling the broadcast interrupt due to the unconditional sum up of local apic timer count and irq0 count. To cover all cases we need to keep track on which CPU irq0 is handled. In theory this is CPU#0 due to the explicit disabling of irq balancing for irq0, but there are systems which ignore this on the hardware level. The per cpu irq0 accounting allows us to remove the irq0 to CPU0 binding as well. Add a per cpu counter for irq0 and evaluate this instead of the global irq0 count in the nmi watchdog code.
