If anyone has any objections, please let me know. ------------------ From: Michael Ellerman commit bfedba3b2c7793ce127680bc8f70711e05ec7a17 upstream. When building for power4, newer binutils don't recognise the "dcbfl" extended mnemonic. dcbfl RA, RB is equivalent to dcbf RA, RB, 1. Switch to "dcbf" to avoid the build error.
