The V4L2_COLORSPACE_470_SYSTEM_M (aka NTSC 1953) colorspace has a different
whitepoint (C) compared to Rec. 709 (D65). The Bradford method is the
recommended method to compensate for that when converting a Rec. 709 color
to an NTSC 1953 color.
See http://www.brucelindbloom.com/index.html?Eqn_ChromAdapt.html for more
details on the Bradford method.
This patch updates the Rec. 709 to NTSC 1953 matrix so that it includes the
chromatic adaptation as calculated by the Bradford method, and it recalculates
the tpg_csc_colors table accordingly.

Every time compat32 encounters an unknown ioctl it will call pr_warn.
However, that's very irritating since it is perfectly normal that this
happens. For example, applications often try to call an ioctl to see if
it exists, and if that's used with an older kernel where compat32 doesn't
support that ioctl yet, then it starts spamming the kernel log.
So replace pr_warn by pr_debug.

rcar_vin_set_fmt() defaults to PAL when the subdevice's querystd() method call
fails (e.g. due to I2C error). This doesn't work very well when a camera being
used outputs NTSC which has different order of fields and resolution. Let us
stop pretending and return the actual error except when the querystd() method
is not implemented, in which case we'll have to set the 'field' variable to
V4L2_FIELD_NONE.
Note that doing this would prevent video capture on at least Renesas Henninger/
Porter boards where I2C seems particularly buggy.

rq_data_dir() returns either READ or WRITE (0 == READ, 1 == WRITE), not
a boolean value.
Now, admittedly the "!= 0" doesn't really change the value (0 stays as
zero, 1 stays as one), but it's not only redundant, it confuses gcc, and
causes gcc to warn about the construct
switch (rq_data_dir(req)) {
case READ:
...
case WRITE:
...
that we have in a few drivers.
Now, the gcc warning is silly and stupid (it seems to warn not about the
switch value having a different type from the case statements, but about
_any_ boolean switch value), but in this case the code itself is silly
and stupid too, so let's just change it, and get rid of warnings like
this:
drivers/block/hd.c: In function ‘hd_request’:
drivers/block/hd.c:630:11: warning: switch condition has boolean value [-Wswitch-bool]
switch (rq_data_dir(req)) {
The odd '!= 0' came in when "cmd_flags" got turned into a "u64" in
commit 5953316dbf ("block: make rq->cmd_flags be 64-bit") and is
presumably because the old code (that just did a logical 'and' with 1)
would then end up making the type of rq_data_dir() be u64 too.
But if we want to retain the old regular integer type, let's just cast
the result to 'int' rather than use that rather odd '!= 0'.

Fix up the writeback plugging introduced in commit d353d7587d
("writeback: plug writeback at a high level") that then caused problems
due to the unplug happening with a spinlock held.
* writeback-plugging:
writeback: plug writeback in wb_writeback() and writeback_inodes_wb()
Revert "writeback: plug writeback at a high level"
We had to revert the pluggin in writeback_sb_inodes() because the
wb->list_lock is held, but we could easily plug at a higher level before
taking that lock, and unplug after releasing it. This does that.
Chris will run performance numbers, just to verify that this approach is
comparable to the alternative (we could just drop and re-take the lock
around the blk_finish_plug() rather than these two commits.
I'd have preferred waiting for actual performance numbers before picking
one approach over the other, but I don't want to release rc1 with the
known "sleeping function called from invalid context" issue, so I'll
pick this cleanup version for now. But if the numbers show that we
really want to plug just at the writeback_sb_inodes() level, and we
should just play ugly games with the spinlock, we'll switch to that.

I didn't notice this when merging the thermal code from Zhang, but his
merge (commit 5a924a07f882: "Merge branches 'thermal-core' and
'thermal-intel' of .git into next") of the thermal-core and
thermal-intel branches was wrong.
In thermal-core, commit 17e8351a77 ("thermal: consistently use int for
temperatures") converted the thermal layer to use "int" for
temperatures.
But in parallel, in the thermal-intel branch commit d0a12625d2
("thermal: Add Intel PCH thermal driver") added support for the intel
PCH thermal sensor using the old interfaces that used "unsigned long"
pointers.
This resulted in warnings like this:
drivers/thermal/intel_pch_thermal.c:184:14: warning: initialization from incompatible pointer type [-Wincompatible-pointer-types]
.get_temp = pch_thermal_get_temp,
