Log message:
Apply (with slight variants) this elimination of bzero() with M_ZERO:

- if ((mapstore = malloc(mapsize, M_DEVBUF,
- (flags & BUS_DMA_NOWAIT) ? M_NOWAIT : M_WAITOK)) == NULL)
+ if ((mapstore = malloc(mapsize, M_DEVBUF, (flags & BUS_DMA_NOWAIT) ?
+ (M_NOWAIT | M_ZERO) : (M_WAITOK | M_ZERO))) == NULL)
return (ENOMEM);

- bzero(mapstore, mapsize);
