This patch enables PPC_TRANSACTIONAL_MEM (Support user-mode Transactional
Memory on PowerPC), which depends on PPC_BOOK3S_64 (enabled on the Debian
kernel build) and selects VSX.
The help text for VSX mentions it causes no harm on processors that do not
support VSX (only adds code):
"""
This option is only useful if you have a processor that supports
VSX (P7 and above), but does not have any affect on a non-VSX
CPUs (it does, however add code to the kernel).
""" [arch/powerpc/platforms/Kconfig.cputype]
So, I believe it is useful and safe for both powerpc64 and powerpc64le.
