When using '!Ffile function' in a docbook template, and the function no
longer exists, you get a "no structured comments found" error from the
kernel-doc processing script. It's useful to know which functions it was
looking for, so print them out in this case. Also do the same for '!Pfile
doc-section'
The same error also happens when using '!Efile' when some exported
functions aren't documented (in the same file.) There's a very large
number of such functions though, so don't print the message in this case
-- right now it would give ~850 messages.

When expert configuration option(CONFIG_EXPERT) is enabled, menuconfig
offers a choice of compression algorithm to compress initial ramfs image;
This choice is stored into CONFIG_RD_* variables. But usr/Makefile uses
earlier INITRAMFS_COMPRESSION_* macros to build initial ramfs file. Since
none of them is defined, resulting 'initramfs_data.cpio' file remains
un-compressed.
This patch updates the Makefile to use CONFIG_RD_* variables and adds
support for LZ4 compression algorithm. Also updates the
'gen_initramfs_list.sh' script to check whether a selected compression
command is accessible or not. And fall-back to default gzip(1)
compression when it is not.

Change the message level for memory barrier uses from a --strict test only

So, if checking a patch, scan the original patched file if it's available

CamelCase messages.

As discussed recently on the arm [1] and lm-sensors [2] lists, it is
possible to use section markers on variables in a way which gcc doesn't
understand (or at least not the way the developer intended):
static struct __initdata samsung_pll_clock exynos4_plls[nr_plls] = {
does NOT put exynos4_plls in the .initdata section. The __initdata marker
can be virtually anywhere on the line, EXCEPT right after "struct". The
preferred location is before the "=" sign if there is one, or before the
trailing ";" otherwise.

[2] http://lists.lm-sensors.org/pipermail/lm-sensors/2013-August/039836.html
So, update checkpatch to find these misuses and report an error when it's
immediately after struct or union, and a warning when it's otherwise not
immediately before the ; or =.

There are some cases where checkpatch can take a long time to complete.
Reduce the likelihood of this long run-time by adding a new test for lines
with and without comments and eliminating checks on lines with only
comments.
This reduces the number of "ctx_statement_block" calls, and also the
number of tests of $stat, which is now undefined for these blank lines.
One test in particular, the "check for switch/default statements without a
break", could take an extremely long time to parse as it tries to skip
interleaving comments within the ctx_statement_block/$stat and that could
be done multiple times unnecessarily.
A small test case taken from cfg80211.h before this patch would take
1000's of seconds to run, now it's just a couple seconds.

with messages like:
Nested quantifiers in regex; marked by <--HERE in m/(\((?:[^\(\)]++ <-- HERE |(?-1))*\))/ at ./checkpatch.pl line 340.
The bug reporter was running a version of perl 5.8 which was end-of-lifed
in 2008: http://www.cpan.org/src/. Versions of perl this old are at
_best_ quite untested. At worst, they are crusty and known to be
completely broken.
If folks have a system _that_ old, then we should have mercy on them and
give them a half-decent error message rather than fail with nutty error
messages.
This patch enforces that checkpatch.pl is run with perl 5.10, which was

Note: it is still possible to have more than one symbol that control
tristates, but indirectly:
config MOD1
bool "mod1"

Currently, the 'MODULES' symbol is hard-coded to be the default symbol
that enables/disables tristates, if no other symbol was declared with
'option modules'.
While this used to be needed for the Linux kernel, we now have an
explicit 'option modules' attached to the 'MODULES' symbol (since
cset 11097a036), so we no longer need to special-case it in the
kconfig code.
Furthermore, kconfig is extensively used out of the Linux kernel, and
other projects may have another meaning for a symbol named 'MODULES'.
This patch changes the way we enable/disable tristates: if a symbol was
found with 'option modules' attached to it, then that symbol controls
enabling tristates. Otherwise, tristates are disabled, even if a symbol
named 'MODULES' exists.

A lot of 64-bit systems supported by Linux/MIPS have boot firmware or
bootloaders that only understand 32-bit ELF files, and as such, the vmlinux.32
target exists to support these systems. Therefore, it'd be nice if the tar-pkg
target recognised this, and included the right version when packaging up a
binary of the kernel.
This updates buildtar to support MIPS targets. MIPS may use 'vmlinux'
or 'vmlinux.32' depending on the target system. This uses 'vmlinux.32'
in preference to 'vmlinux' where present (although I should check which
is newer), including either file as /boot/vmlinux-${version}.

When a symbol changes type from tristate to bool, and was previously set to
'm', a subsequent silentoldconfig would warn about inconsistency, such as:
include/config/auto.conf:3014:warning: symbol value 'm' invalid for
HOTPLUG_PCI_PCIE
Seen by Linus with the merge in aa8032b (sequence to reproduce by Michal):
git checkout 1fe0135
make mrproper
make allmodconfig
make silentoldconfig
git checkout aa8032b
make allmodconfig
make silentoldconfig
Since HOTPLUG_PCI_PCIE changed from tristate to bool in aa8032b, it was
previously set to 'm' in auto.conf by the first allmodconfig+silentoldconfig,
but then was set to 'y' by the second allmodconfig. Then the second
silentoldconfig prints the warning.
The warning in this case is a spurious warning, which happens at the time
kconfig tries to detect symbols that have changed, to touch the empty
header files in include/config used for dependency-tracking by make.
Silence the warning when we read the old auto.conf file, since it is
perfectly legit that a symbol changed type since the previous call.

Script `config' relies on extensions of `GNU sed', and is thus not
working on all Unixes:
- in-place edition of files (-i), which can be replaced with
a temporary file;
- extended-regexps (-r), which can be split into basic regexps;
- single-line calls to `a' command, while some implementations
require a leading newline before the parameter.
Rewrite calls to `sed' to comply with POSIX interface, and move them
to helper functions.

Instead of using "long" for kconfig "hex" and "range" values, which may
change in size depending on the host architecture, use "long long". This
will allow values greater than INT_MAX on 32-bit hosts when cross
