Sorry for the earlier noise. ]

Today's tree has a number of new mips related build errors.
Building mips:defconfig ... failed
Building mips:allmodconfig ... failed

Bisect points to commit 9119e8276d ("MIPS: asm: hazards: Add MIPSR6
definitions"). Looking into the patch, I wonder if the following is correct.
-#if defined(CONFIG_CPU_MIPSR2) && !defined(CONFIG_CPU_CAVIUM_OCTEON)
+#if defined(CONFIG_CPU_MIPSR2) || defined(CONFIG_CPU_MIPSR6) && !defined(CONFIG_CPU_CAVIUM_OCTEON)
This change appears to be missing a ( ) around the first two defined()
statements. Fixing that doesn't resolve the problem, though. Reverting
the patch doesn't fix the problem either, so something else must be wrong.

Bisect points to commit 2f1da3620ff2 ("MIPS: Emulate the new MIPS R6 branch
compact (BC) instruction"). Looking into the code, the patch quite obviously
conflicts with cavium support.
