This option enables undefined behaviour sanity checker
Compile-time instrumentation is used to detect various undefined
behaviours in runtime. Various types of checks may be enabled
via boot parameter ubsan_handle
(see: Documentation/dev-tools/ubsan.rst).

default y
help
This option activates instrumentation for the entire kernel.
If you don't enable this option, you have to explicitly specify
UBSAN_SANITIZE := y for the files/directories you want to check for UB.
Enabling this option will get kernel image size increased
significantly.
config UBSAN_ALIGNMENT
bool "Enable checking of pointers alignment"
depends on UBSAN
default y if !HAVE_EFFICIENT_UNALIGNED_ACCESS
help
This option enables detection of unaligned memory accesses.
Enabling this option on architectures that support unaligned
accesses may produce a lot of false positives.
config UBSAN_NULL
bool "Enable checking of null pointers"
depends on UBSAN
default y if !ARCH_WANTS_UBSAN_NO_NULL
help
This option enables detection of memory accesses via a
null pointer.

net: phy: Add LED mode driver for Microsemi PHYs.
LED Mode:
Microsemi PHY support 2 LEDs (LED[0] and LED[1]) to display different
status information that can be selected by setting LED mode.
LED Mode parameter (vsc8531, led-0-mode) and (vsc8531, led-1-mode) get
from Device Tree.
