Subject: xtensa: enforce slab alignment to maximum register width
From: Oskar Schirmer <os@xxxxxxxxx>
XCHAL_DATA_WIDTH is the maximum register width, slab caches should be
aligned to this.
Theoretical fix as all variants have had an XCHAL_DATA_WIDTH of 4
(wordsize) for now. But the S6000 variant will raise this to 16.
