defconfig: add BLX
ARM: module: add text.unlikely section to unwind

Add handling for the .text.unlikely unwind sections for cases where
real used code get incorrectly placed by compiler. This solves cases
in which a frequently used function triggers the collectoin of the
current stack trace when using CONFIG_ARM_UNWIND. An example would
be when using CONFIG_SLUB_DEBUG. The constant error printing can
flood the kernel log buffers and cause sluggishness.
