This code only works for arm64 as it is storing and restoring arm64 registers.
armv7 registers are different so this code does not work for the generic arm.

arm64 specific code, we always named as arm64

F: lib/librte_hash/rte*_arm64.h
F: lib/librte_efd/rte*_arm64.h
F: lib/librte_table/rte*_arm64.h

IMO, If armv7 support adds in future then we can change the directory
as arch/arm
and have ctx_64.c and ctx_32.c etc. I think, for now, technically it
is correct to call the directory as arm64
