Using a #define ending in a semicolon is poor style and can lead to
unexpected code paths being executed.
Warn on uses of these #define types:
#define foo[(...)] bar;
#define foo[(...)] \
bar;

We attempt to search for compatible strings which use a variable token in
the documented name such as <chip> or <soc>. While this was attempted to
be handled, it's utterly broken.
The desired forms of matching are:
vendor,<chip>-*
vendor,name<part#>-*
For <chip>, lower case characters and numbers are permitted. For <part#>,
only numeric values are allowed.
With this change, the number of missing compatible strings reported in
arch/arm/boot/dts is reduced from 1071 to 960.

Recordmcount utility under scripts is run, after compiling each object,
to find out all the locations of calling _mcount() and put them into
specific seciton named __mcount_loc.
Then linker collects all such information into a table in the kernel image
(between __start_mcount_loc and __stop_mcount_loc) for later use by ftrace.
This patch adds arm64 specific definitions to identify such locations.
There are two types of implementation, C and Perl. On arm64, only C version
is used to build the kernel now that CONFIG_HAVE_C_RECORDMCOUNT is on.
But Perl version is also maintained.
This patch also contains a workaround just in case where a header file,
elf.h, on host machine doesn't have definitions of EM_AARCH64 nor
R_AARCH64_ABS64. Without them, compiling C version of recordmcount will
fail.

When building the firmware blobs, use a simple loop to create
directories in $(objtree), like in Makefile.build. This simplifies the
rules and also makes it possible to set $(objtree) to '.' later. Before
this change, a dependency on $(objtree)/<dir> would be satisfied by
<dir> in $(srctree).
When installing the firmware blobs, call mkdir like in Makefile.modinst.

Currently, while using ctags to read code, we would get stumbled on
PageCgroup* symbols: no definition found. And it is quite dull to
manually dig it out.
This patch adds regular expression replacement pattern for such symbols,
like what have done for the PageXXX flag. It will teach ctags to find
out the definition for us.

Kbuild is supposed to support mixed targets. (%config and build targets)
But "make all" did nothing if it was run with configuration targets.
For example,
$ LANG=C make defconfig all
HOSTCC scripts/basic/fixdep
HOSTCC scripts/kconfig/conf.o
SHIPPED scripts/kconfig/zconf.tab.c
SHIPPED scripts/kconfig/zconf.lex.c
SHIPPED scripts/kconfig/zconf.hash.c
HOSTCC scripts/kconfig/zconf.tab.o
HOSTLD scripts/kconfig/conf
*** Default configuration is based on 'x86_64_defconfig'
#
# configuration written to .config
#
make: Nothing to be done for `all'.
This commits allows "make %config all" and makes sure
mixed targets are built one by one in the given order.

W=... provides extra gcc checks.
Having such code in scripts/Makefile.build results in the same flags
being added to KBUILD_CFLAGS multiple times becuase
scripts/Makefile.build is invoked every time Kbuild descends into
the subdirectories.
Since the top Makefile is already too cluttered, this commit moves
all of extra gcc check stuff to a new file scripts/Makefile.extrawarn,
which is included from the top Makefile.

Pull misc kbuild changes from Michal Marek:

- scripts/tags.sh does not index the generated *.mod.c files
- new objdiff tool to list differences between two versions of an
object file
- A fix for scripts/bootgraph.pl"

scripts/coccinelle: Use PTR_ERR_OR_ZERO
scripts/bootgraph.pl: Add graphic header
scripts: objdiff: detect object code changes between two commits
Coccicheck: Remove memcpy to struct assignment test
scripts/tags.sh: Ignore *.mod.c
