To address the case where only a couple of registers are needed, kernel_neon_begin_partial(u32) is introduced which takes as a parameter the number of bottom 'n' NEON q-registers required. To mark the end of such a partial section, the regular kernel_neon_end() should be used.

The names are identical to the ones used in arm/ so code using intrinsics or vectorized by GCC can be shared between arm and arm64.
