PROVE_LOCKING enables LOCKDEP, which causes big overhead on cache and
bus transactions.
On some ARM big.LITTLE architecutres (Exynos 5433) the overhead is really big.
The overhead can be measures using hackbench which will speed up
by x3 times (11sec -> 3.4sec).
When you check transaction on cache or buses, the results are way higher
than normal for the same hackbench test:
L1d cache invalidations: 26mln vs 4mln
L2u cache invalidations: 42mln vs 12mln
bus cyc/access: 30cyc/access vs. 20cyc/access
context switch is x3 times cheaper
Enable this option only when you have some locking issue to investigate.

Enable the base GCC plugin support symbol CONFIG_GCC_PLUGINS for
multi_v7_defconfig so that builds hosted on systems that have a
supported version of GCC along with the prerequisite headers will
allow GCC plugins to be used during the build. At the moment, this
will also enable the ARM per-task stack protector plugin, since
all its remaining Kconfig dependencies are fulfilled by default.
At the same time, enable the structleak plugin. This plugin ensures
that local struct type variables are fully initialized, preventing
inadvertent leaks of kernel state if such variables are shared with
userland. This is a reasonable transformation to apply by default,
since it does not adversely affect performance, and does not affect
GCC compiler diagnostics regarding the use of uninitialized local
variables.

None of the LPC32xx device trees contains any display settings,

as "disabled" on lpc3250-ea3250 and "okay" on lpc3250-phy3250

- I mis-tagged the 'drivers' branch, and missed 3 patches. Merged in

platform-specific drivers (serial, etc). This also include DTs for
two boards with this SoC, OrangePi 2G and OrangePi i86.
- i.MX8 is another new platform (NXP, 4x Cortex-A53 + Cortex-M4, 4K
video playback offload). This is the first i.MX 64-bit SoC.
- Some minor updates to Samsung boards (adding a few peripherals in

Pull ARM SoC defconfig updates from Olof Johansson:
"Most changes here are to enable new drivers and platforms in the
various configs that affect them. Most of these have been covered and
described in the other branches, we mostly keep defconfig separate to
avoid conflicts between SoC/dt/driver updates that they otherwise
would be grouped with.
One thing worth mentioning here is that OMAP changes from using their
own UART driver, to 8250, for the multi_v7_defconfig shared config on
32-bit. This means that the console is now named ttyS* instead of
ttyO*. This change was already done for omap2_defconfig a while back,
so most users of these configs have either already updated, or can
easily follow the same patterns as they did at that time. This makes
platform support slightly easier for distros, since they no longer
need to keep track of a separate console prefix for these platforms"

Defconfig changes for omaps for v4.21 merge window
We're finally changing omaps to use 8250_OMAP instead of SERIAL_OMAP
for multi_v7_defconfig. This will make things much easier for distros,
and the kernel already warns about the kernel console getting
redirected with CONFIG_SERIAL_8250_OMAP_TTYO_FIXUP defaulting to y.
People using /etc/inittab still need to s/ttyO/ttyS/ if using the
out-of-box multi_v7_defconfig, and that did not seem to be an issue
when we moved omap2plus_defconfig to use 8250_OMAP earlier.
The other change is to enable CONFIG_SND_SOC_TLV320AIC23_I2C as a
loadable module that I forgot to send a pull request for earlier.
