All parisc builds fail.

There are also lots of warnings.

./include/linux/slab.h:208: warning: "ARCH_KMALLOC_MINALIGN" redefined
  208 | #define ARCH_KMALLOC_MINALIGN ARCH_DMA_MINALIGN

./arch/parisc/include/asm/cache.h:28: note: this is the location of the previous definition
   28 | #define ARCH_KMALLOC_MINALIGN   16      /* ldcw requires 16-byte alignment */

Bisect log attached. Reverting the offending patch fixes the build error and the warnings.
