Android has an unusual setup where the kernel needs to target
[arch]-linux-gnu to avoid Android userspace-specific flags and
optimizations, but AOSP doesn't ship a matching binutils.
Add a new variable CLANG_TRIPLE which can override the "-target" triple
used to compile the kernel, while using a different CROSS_COMPILE to
pick the binutils/gcc installation. For Android you'd do something
like:
export CLANG_TRIPLE=aarch64-linux-gnu-
export CROSS_COMPILE=aarch64-linux-android-
If you don't need something like this, leave CLANG_TRIPLE unset and it
will default to CROSS_COMPILE.

clang generates plenty of these warnings in different parts of the code.
They are mostly caused by container_of() and other macros which declare
a "const <type> *" variable for their internal use which triggers a
"duplicate 'const' specifier" warning if the <type> is already const
qualified.

(cherry picked from commit bfb38988c5)
cc-option uses KBUILD_CFLAGS and KBUILD_CPPFLAGS when it determines
whether an option is supported or not. This is fine for options used to
build the kernel itself, however some components like the x86 boot code
use a different set of flags.
Add the new macro __cc-option which is a more generic version of
cc-option with additional parameters. One parameter is the compiler
with which the check should be performed, the other the compiler options
to be used instead KBUILD_C*FLAGS.
Refactor cc-option and hostcc-option to use __cc-option and move
hostcc-option to scripts/Kbuild.include.

Since commit c3f0d0bc5b ("kbuild, LLVMLinux: Add -Werror to
cc-option to support clang"), cc-option and friends work nicely
for clang.
However, -Wno-unknown-warning-option makes clang happy with any
unknown warning options even if -Werror is specified.
Once -Wno-unknown-warning-option is added, any succeeding call of
cc-disable-warning is evaluated positive, then unknown warning
options are accepted. This should be dropped.

The Linux Kernel relies on GCC's acceptance of inline assembly as an
opaque object which will not have any validation performed on the content.
The current behaviour in LLVM is to perform validation of the contents by
means of parsing the input if the MC layer can handle it.
Disable clangs integrated assembler and use the GNU assembler instead.

Add cross target to CC if using clang. Also add custom gcc toolchain
path for fallback gcc tools.
Clang will fallback to using things like ld, as, and libgcc if
(respectively) one of the llvm linkers isn't available, the integrated
assembler is turned off, or an appropriately cross-compiled version of
compiler-rt isn't available. To this end, you can specify the path to
this fallback gcc toolchain with GCC_TOOLCHAIN.

commit bd664f6b3e upstream.
I made the mistake of upgrading my desktop to the new Fedora 26 that
comes with gcc-7.1.1.
There's nothing wrong per se that I've noticed, but I now have 1500
lines of warnings, mostly from the new format-truncation warning
triggering all over the tree.
We use 'snprintf()' and friends in a lot of places, and often know that
the numbers are fairly small (ie a controller index or similar), but gcc
doesn't know that, and sees an 'int', and thinks that it could be some
huge number. And then complains when our buffers are not able to fit
the name for the ten millionth controller.
These warnings aren't necessarily bad per se, and we probably want to
look through them subsystem by subsystem, but at least during the merge
window they just mean that I can't even see if somebody is introducing
any *real* problems when I pull.
So warnings disabled for now.

commit 7292ae3d5a upstream.
The latest change of asm goto support check added passing of KBUILD_CFLAGS
to compiler. When these flags reference gcc plugins that are not built yet,
the check fails.
When one runs "make bzImage" followed by "make modules", the kernel is always
built with HAVE_JUMP_LABEL disabled, while the modules are built depending on
CONFIG_JUMP_LABEL. If HAVE_JUMP_LABEL macro happens to be different, modules
are built with undefined references, e.g.:
ERROR: "static_key_slow_inc" [net/netfilter/xt_TEE.ko] undefined!
ERROR: "static_key_slow_dec" [net/netfilter/xt_TEE.ko] undefined!
ERROR: "static_key_slow_dec" [net/netfilter/nft_meta.ko] undefined!
ERROR: "static_key_slow_inc" [net/netfilter/nft_meta.ko] undefined!
ERROR: "nf_hooks_needed" [net/netfilter/ipvs/ip_vs.ko] undefined!
ERROR: "nf_hooks_needed" [net/ipv6/ipv6.ko] undefined!
ERROR: "static_key_count" [net/ipv6/ipv6.ko] undefined!
ERROR: "static_key_slow_inc" [net/ipv6/ipv6.ko] undefined!
This change moves the check before all these references are added
to KBUILD_CFLAGS. This is correct because subsequent KBUILD_CFLAGS
modifications are not relevant to this check.
