The current code includes 'Kconfig' in ALLSOURCE_ARCHS, but
it should not (Kconfig is not an architecture). Replace this
with a find-generated string and directly assign it to
$ALLSOURCE_ARCHS. The find_all_archs() function is no longer
needed for a one-liner with obvious semantics, so inline the
arch generation into the surrounding conditional.

Move rules looking for some special cases of safe dereferences before
the collection of NULL-tested values.  The special cases are fairly
rare, but somewhat costly to find, because isomorphisms create many
variants of the rules.  There is thus no need to search for them over
and over for each NULL tested expression.  Collecting them just once
is sufficient and more efficient.

This requires further changes to linker script to KEEP some tables
and wildcard compiler generated sections into the right place. This
includes pp32 modifications from Christophe Leroy.

When compiling powernv_defconfig with this option, the resulting
kernel is almost 400kB smaller (and still boots):

11752437   4598858   1338776   17690071   vmlinux.dcde

Mathieu's numbers for custom Mac Mini G4 config has almost 200kB
saving. It also had some increase in vmlinux size for as-yet
unknown reasons.

KEEP more tables, and add the function/data section wildcard to more
section selections.

This is a little ad-hoc at the moment, but kernel code should be moved
to consistently use .text..x (note: double dots) for explicit sections
and all references to it in the linker script can be made with
TEXT_MAIN, and similarly for other sections.

For now, let's see if major architectures move to enabling this option
then we can do some refactoring passes. Otherwise if it remains unused
or superseded by LTO, this may not be required.

There is multiple issues with the genaration of maintainer string

It uses DEBEMAIL and EMAIL enviroment variables, which may contain angle brackets,
creating invalid maintainer strings. The documented KBUILD_BUILD_USER and
KBUILD_BUILD_HOST variables are not used. Undocumented and uncommon NAME
variable is used. Refactor the Maintainer string to:

- use EMAIL or DEBEMAIL directly if they are in form "name <user@host>"
- use KBUILD_BUILD_USER and KBUILD_BUILD_HOST if set before falling
  back to autodetection
- no longer use NAME variable or the useless Anonymous string

The logic is switched from multiline if/then/fi statements to compact
shell variable substition commands.

The root cause of the problem is starting hrtimer with an expiry time
already in the past can take more than 20 milliseconds to trigger the
timer function.  It can be solved by forward such past timers
immediately, rather than submitting them to hrtimer_start().
In case the timer is periodic, update the target expiration and call
hrtimer_start with it.

v2: Check if the tsc deadline is already expired. Thank you Mika.
v3: Execute the past timers immediately rather than submitting them to
hrtimer_start().
v4: Rearm the periodic timer with advance_periodic_target_expiration() a
simpler version of set_target_expiration(). Thank you Paolo.

 "This is our first pull request of the rc cycle. It's not that it's
  been overly quiet, we were just waiting on a few things before sending
  this off.

  For instance, the 6 patch series from Intel for the hfi1 driver had
  actually been pulled in on Tuesday for a Wednesday pull request, only
  to have Jason notice something I missed, so we held off for some
  testing, and then on Thursday had to respin the series because the
  very first patch needed a minor fix (unnecessary cast is all).

  There is a sizable hns patch series in here, as well as a reasonably
  largish hfi1 patch series, then all of the lines of uapi updates are
  just the change to the new official Linux-OpenIB SPDX tag (a bunch of
  our files had what amounts to a BSD-2-Clause + MIT Warranty statement
  as their license as a result of the initial code submission years ago,
  and the SPDX folks decided it was unique enough to warrant a unique
  tag), then the typical mlx4 and mlx5 updates, and finally some cxgb4
  and core/cache/cma updates to round out the bunch.

  None of it was overly large by itself, but in the 2 1/2 weeks we've
  been collecting patches, it has added up :-/.

  As best I can tell, it's been through 0day (I got a notice about my
  last for-next push, but not for my for-rc push, but Jason seems to
  think that failure messages are prioritized and success messages not
  so much). It's also been through linux-next. And yes, we did notice in
  the context portion of the CMA query gid fix patch that there is a
  dubious BUG_ON() in the code, and have plans to audit our BUG_ON usage
  and remove it anywhere we can.
