Keep AOSP changes and discard LTS binder changes, since these LTS changes
have already been merged and further refactored in AOSP tree long ago.
Conflicts:
kernel/sched/sched.h
Refactor the changes from LTS commit 62208707b4
("sched/cputime: Fix prev steal time accouting during CPU hotplug")
to align with the changes from AOSP commit dee8fa1552
("sched: backport cpufreq hooks from 4.9-rc4").

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.

[ Upstream commit 35f860f9ba ]
Some versions of ARM GCC compiler such as Android toolchain throws in a
'-fpic' flag by default. This causes the gcc-goto check script to fail
although some config would have '-fno-pic' flag in the KBUILD_CFLAGS.
This patch passes the KBUILD_CFLAGS to the check script so that the
script does not rely on the default config from different compilers.
