Your commits 430857eae56c ("MIPS: mm: Add MIPS R6 instruction encodings") and 90163242784b ("MIPS: kernel: unaligned: Add support for the MIPS R6") are included in yesterday's linux-next (ie, next-20150213). I noticed because a script I use to check linux-next spotted a problem with it. These commits added three references to CONFIG_MIPS_R6, were probably CONFIG_CPU_MIPSR6 was intended. One reference is in a comment, which should be trivial to get fixed. The other two references are in (negative) preprocessor checks. It's not certain, at least not to me, how these should be fixed.
