MFC r283547:

Ensure that all arm kernel configs contain ALT_BREAK_TO_DEBUGGER and not
BREAK_TO_DEBUGGER if they have a serial console (most do). A burst of
serial line noise (such as unplugging a usb serial adapter) can look like
a break and drop a working system into the debugger. The alt break sequence
(<CR>~^B) works fine on both serial and non-serial consoles.

MFC r279837:

Remove MODULES_OVERRIDE="" and WITHOUT_MODULES="ahc" from armv6 configs.

MFC r276004: Fix the indentation to simplify comparing the ARM config files.

MFC r276003:

Start to clean up the armv6 kernel configs by reducing the diff between
them in the first sections and the later FDT support.

MFC r276642, r276644:

Remove commented-out options SMP and APIC_IO from old arm boards that will
never be able to support smp.

Switch all arm kernels with option SMP to use SCHED_ULE instead of 4BSD.

MFC r266647, r270912, r273089:

Reduce the diff between the PandaBoard and BeableBone kernel configs

Resync comments about scbus and pass for life after AHCI joined CAM.

Uncomment general options from the Pandaboard config. These are in other
configs and there is no reason for them not to be here.

MFC r266943, r266950, r267390:

Add support for Exynos 5420 Octa - 8-core (big.LITTLE) ARM machine
Enable SMP for both Exynos5 models we support.
