Message-ID<qsZ3c-1rz-11@gated-at.bofh.it>
According to the discussion on the mailing list, this version adds a new patch
to force select FRAME_POINTER for ARM64.

Change v2 --> v1:
1. Adds a new patch to force select FRAME_POINTER
2. Notes that this change adds a dependency on DEBUG_KERNEL for building with
frame pointers

Message-ID<qsZ3e-1rz-41@gated-at.bofh.it>
In reply to#1265913
FRAME_POINTER is defined in lib/Kconfig.debug, it is unnecessary to redefine
it in arch/arm64/Kconfig.debug. Actually, the one defined in arm64 directory
is never used.
This adds a dependency on DEBUG_KERNEL for building with frame pointers.

I just thought it may be clearer in this way. If nobody thinks it is 
necessary, I definitely could merge them into one.

Thanks,

Do you really need two patches for this?
