Since unsigned long is 64 bits, a # 64-bit load needs to be used to load it, unless an endianness specific # correction offset is added to access the desired subpart. In this # case there is no reason to _not_ use a 64 bit load though. # # Fixes: 6c85b7bc637b ("powerpc/kvm: Use UV_RETURN ucall to return to ultravisor") # Cc: stable@vger.kernel.org # v5.4+ #
