Update code that relied on sched.h including various MM types for them.

We are going to separate all the MM types that are embedded directly in 'struct task_struct'
into the new <linux/mm_types_task.h> header.
Create a new <linux/mm_types_task.h> that only contains some includes from mm_types.h itself.
This should be trivially correct and easy to bisect to.
(This patch does not materially move the types yet.)

Instead of including the full <linux/signal.h>, we are going to include the
types-only <linux/signal_types.h> header in <linux/sched.h>, to further
decouple the scheduler header from the signal headers.
This means that various files which relied on the full <linux/signal.h> need
to be updated to gain an explicit dependency on it.
Update the code that relies on sched.h's inclusion of the <linux/signal.h> header.

<linux/kasan.h> is a low level header that is included early
in affected kernel headers. But it includes <linux/sched.h>
which complicates the cleanup of sched.h dependencies.
But kasan.h has almost no need for sched.h: its only use of
scheduler functionality is in two inline functions which are
not used very frequently - so uninline kasan_enable_current()
and kasan_disable_current().
Also add a <linux/sched.h> dependency to a .c file that depended
on kasan.h including it.
This paves the way to remove the <linux/sched.h> include from kasan.h.

So rcupdate.h is a pretty complex header, in particular it includes
<linux/completion.h> which includes <linux/wait.h> - creating a
dependency that includes <linux/wait.h> in <linux/sched.h>,
which prevents the isolation of <linux/sched.h> from the derived
<linux/wait.h> header.
Solve part of the problem by decoupling rcupdate.h from completions:
this can be done by separating out the rcu_synchronize types and APIs,
and updating their usage sites.
Since this is a mostly RCU-internal types this will not just simplify
<linux/sched.h>'s dependencies, but will make all the hundreds of
.c files that include rcupdate.h but not completions or wait.h build
faster.
( For rcutiny this means that two dependent APIs have to be uninlined,
but that shouldn't be much of a problem as they are rare variants. )

The length of TASK_STATE_TO_CHAR_STR was still checked using the old
link-time manual error method - convert it to BUILD_BUG_ON(). This
has a couple of advantages:
- it's more obvious what's going on
- it reduces the size and complexity of <linux/sched.h>
- BUILD_BUG_ON() will fail during compilation, with a clearer
error message than the link time assert.

The '__unreachable' and '__func_stack_frame_non_standard' sections are
only used at compile time. They're discarded for vmlinux but they
should also be discarded for modules.
Since this is a recurring pattern, prefix the section names with
".discard.". It's a nice convention and vmlinux.lds.h already discards
such sections.
Also remove the 'a' (allocatable) flag from the __unreachable section
since it doesn't make sense for a discarded section.

Linus reported the following commit broke module loading on his laptop:
d1091c7fa3 ("objtool: Improve detection of BUG() and other dead ends")
It showed errors like the following:
module: overflow in relocation type 10 val ffffffffc02afc81
module: 'nvme' likely not compiled with -mcmodel=kernel
The problem is that the __unreachable section addresses are stored using
the '.long' asm directive, which isn't big enough for .text section
kernel addresses. Use relative addresses instead:
".long %c0b - .\t\n"

The last patch came in about a week ago, but IMHO it's best to
go in now. It is not for the main driver, it's for the bt-bmc
driver, which runs on the managment controller side, not on
the host side, so the scope is limited and the change is
necessary.

Pull IDR rewrite from Matthew Wilcox:
"The most significant part of the following is the patch to rewrite the
IDR & IDA to be clients of the radix tree. But there's much more,
including an enhancement of the IDA to be significantly more space
efficient, an IDR & IDA test suite, some improvements to the IDR API
(and driver changes to take advantage of those improvements), several
improvements to the radix tree test suite and RCU annotations.
The IDR & IDA rewrite had a good spin in linux-next and Andrew's tree
for most of the last cycle. Coupled with the IDR test suite, I feel
pretty confident that any remaining bugs are quite hard to hit. 0-day
did a great job of watching my git tree and pointing out problems; as
it hit them, I added new test-cases to be sure not to be caught the
same way twice"
Willy goes on to expand a bit on the IDR rewrite rationale:
"The radix tree and the IDR use very similar data structures.
Merging the two codebases lets us share the memory allocation pools,
and results in a net deletion of 500 lines of code. It also opens up
the possibility of exposing more of the features of the radix tree to
users of the IDR (and I have some interesting patches along those
lines waiting for 4.12)
It also shrinks the size of the 'struct idr' from 40 bytes to 24 which
will shrink a fair few data structures that embed an IDR"

bugfixes.
A couple changes could theoretically break working setups on upgrade. I
don't expect complaints in practice, but they seem worth calling out
just in case:
- NFS security labels are now off by default; a new
security_label export flag reenables it per export. But,
having them on by default is a disaster, as it generally only
makes sense if all your clients and servers have similar
enough selinux policies. Thanks to Jason Tibbitts for
pointing this out.
- NFSv4/UDP support is off. It was never really supported, and
the spec explicitly forbids it. We only ever left it on out
of laziness; thanks to Jeff Layton for finally fixing that.
