scripts/Makefile adds "selinux" to subdir-y or subdir- twice.
subdir-$(CONFIG_MODVERSIONS) += genksyms
subdir-y += mod
subdir-$(CONFIG_SECURITY_SELINUX) += selinux <--- here
subdir-$(CONFIG_DTC) += dtc
# Let clean descend into subdirs
subdir- += basic kconfig package selinux <--- again
The latter is redundant.

Since commit 22d651dcef ('selftests/powerpc:
Import Anton's memcpy / copy_tofrom_user tests'), some source files in the
tree appear as symlink.
Until commit 8c38a5328a ('scripts/tags.sh:
ignore code of user space tools'), those symlinks made cscope report some
warnings:
$ make ALLSOURCE_ARCHS=all O=./obj-cscope/ cscope
GEN cscope
cscope: cannot find
file .../tools/testing/selftests/powerpc/copyloops/copyuser_power7.S
cscope: cannot find
file .../tools/testing/selftests/powerpc/copyloops/memcpy_64.S
cscope: cannot find
file .../tools/testing/selftests/powerpc/copyloops/memcpy_power7.S
cscope: cannot find
file .../tools/testing/selftests/powerpc/copyloops/copyuser_64.S
In order to prevent the same kind of warnings to be triggered by future
addition of symlinks, the best option is to ignore all symlinks when
building the file list to be processed by cscope (and other tools
supported by scripts/tags.sh).
Ignoring symlinks won't hide source files from cscope (and others) as the
target of these symlinks already appear somewhere else in the tree, and,
as such, should be processed by cscope (or others).
Note that, cscope, when used with -R option to make it find the files to
process by itself, already skip symlinks: it's not expected that cscope
access source files through symlink.
On top of commit 8c38a5328a ('scripts/tags.sh:
ignore code of user space tools'), scripts/tags.sh output from
"make cscope tags TAGS" is the same with and without this patch: it doesn't
seems to introduce any regression (on Fedora 20).

Pull arm64 updates from Catalin Marinas:
- Optimised assembly string/memory routines (based on the AArch64
Cortex Strings library contributed to glibc but re-licensed under
GPLv2)
- Optimised crypto algorithms making use of the ARMv8 crypto extensions
(together with kernel API for using FPSIMD instructions in interrupt
context)
- Ftrace support
- CPU topology parsing from DT
- ESR_EL1 (Exception Syndrome Register) exposed to user space signal
handlers for SIGSEGV/SIGBUS (useful to emulation tools like Qemu)
- 1GB section linear mapping if applicable
- Barriers usage clean-up
- Default pgprot clean-up
Conflicts as per Catalin.

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.
