[PATCH v3 0/4] Generalize fncpy availability

Hi all,

This patch series makes ARM's fncpy() implementation more generic (dropping the
Thumb-specifics) and available in an asm-generic header file.

Tested on a Broadcom ARM64 STB platform with code that is written to SRAM.

Changes in v3 (thanks Doug!):
- correct include guard names in asm-generic/fncpy.h to __ASM_FNCPY_H
- utilize Kbuild to provide the fncpy.h header on ARM64

Changes in v2:
- leave the ARM implementation where it is
- make the generic truly generic (no)

This is helpful in making SoC-specific power management code become true drivers
that can be shared between different architectures.

Thanks!
