When I cleanup FRME_POINTER use for arm64 arch, I found some other
architectures need the similar cleanup. So, I came up with the patch series
for them.
Yang Shi (4):
m32r: remove redundant FRAME_POINTER kconfig option
hexagon: select ARCH_WANT_FRAME_POINTERS instead of defining FRAME_POINTER
avr32: select ARCH_WANT_FRAME_POINTERS and set DEBUG_KERNEL in defconfigs
h8300: set DEBUG_KERNEL in defconfigs

FRAME_POINTER is defined in lib/Kconfig.debug, it is unnecessary to redefine
it in arch/m32r/Kconfig.debug. Actually, the one defined in arch directory
is never used.
