commit 672917dcc78 ("cpuidle: menu governor: reduce latency on exit")
added an optimization, where the analysis on the past idle period moved
from the end of idle, to the beginning of the new idle.Unfortunately, this optimization had a bug where it zeroed one key
variable for new use, that is needed for the analysis. The fix is
simple, zero the variable after doing the work from the previous idle.During the audit of the code that found this issue, another issue was
also found; the ->measured_us data structure member is never set, a
local variable is always used instead.Signed-off-by: Arjan van de Ven

Some time ago we stopped the clean/active metadata updates
from being written to a 'spare' device in most cases so that
it could spin down and say spun down. Device failure/removal
etc are still recorded on spares.However commit 51d5668cb2e3fd1827a55 broke this 50% of the time,
depending on whether the event count is even or odd.
The change log entry said:This means that the alignment between 'odd/even' and
'clean/dirty' might take a little longer to attain,how ever the code makes no attempt to create that alignment, so it
could take arbitrarily long.So when we find that clean/dirty is not aligned with odd/even,
force a second metadata-update immediately. There are already cases
where a second metadata-update is needed immediately (e.g. when a
device fails during the metadata update). We just piggy-back on that.Reported-by: Joe Bryant

An earlier regression fix for the mxb driver (V4L/DVB: saa7146_vv: fix
regression where v4l2_device was registered too late) caused a new
regression in the av7110 driver.Reverted the old fix and fixed the problem in the mxb driver instead.
Tested on mxb and budget-av cards.The real problem is that the saa7146 framework has separate probe()
and attach() driver callbacks which should be rolled into one. This
is now done for the mxb driver, but others should do the same. Lack
of hardware makes this hard to do, though. I hope to get hold of some
hexium cards and then I can try to improve the framework to prevent
this from happening again.Signed-off-by: Hans Verkuil

With fa35b4926, I broke a lot of PNP resource assignment. That commit made
PNPACPI include bridge windows as PNP resources, and PNP resource assignment
treats any enabled overlapping PNP resources as conflicts. Since PCI host
bridge windows typically include most of the I/O port space, this makes PNP
port assigments fail.The PCI host bridge driver will eventually use those PNP window resources,
so we should make PNP ignore them when checking for conflicts.This fixes https://bugzilla.kernel.org/show_bug.cgi?id=15903
