Currently we conditionally add the entity load to the rq when moving
the task between cgroups.
This doesn't make sense as we always 'migrate' the task between
cgroups, so we should always migrate the load too.
[ The history here is that we used to only migrate the blocked load
which was only meaningfull when !queued. ]

924e101a7a ("x86/debug: Dump family, model, stepping of the
boot CPU") had its good intentions to dump the exact F/M/S as an
aid during debugging sessions but its output can be ambiguous.
Fix that:
-smpboot: CPU0: Intel Core Processor (Broadwell) (fam: 06, model: 47, stepping: 02)
+smpboot: CPU0: Intel Core Processor (Broadwell) (family: 0x6, model: 0x47, stepping: 0x2)
Also, spell out "family".

UV: NMI: insert this_cpu_read accessor function on uv_hub_nmi.
On SGI UV systems a 'power nmi' command from the CMC causes
all processors to drop into uv_handle_nmi(). With the 4.0
kernel this results in
BUG: unable to handle kernel paging request
The bug is caused by the current code trying to use the PER_CPU
variable uv_cpu_nmi.hub without an appropriate accessor
function. That oversight occurred in
commit e16321709c ("uv: Replace __get_cpu_var")
Author: Christoph Lameter <cl@linux.com>
Date: Sun Aug 17 12:30:41 2014 -0500
This patch inserts this_cpu_read() in the uv_hub_nmi macro
restoring the intended functionality.
