	The information about where the manufacturer puts the bad block markers inside the bad block and in the OOB data is stored in different places. Let's move this information to the chip struct, as we did it for rawnand.

2018-06-12	treewide: kzalloc() -> kcalloc()	Kees Cook
	The kzalloc() function has a 2-factor argument form, kcalloc(). This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a * b, gfp) as well as handling cases of: kzalloc(a * b * c, gfp) with: kzalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kzalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) \| kzalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

2018-03-15	mtd: Move onenand code base to drivers/mtd/nand/onenand	Boris Brezillon
	Move onenand code base to the drivers/mtd/nand directory in the hope that someday someone will patch it to use the generic NAND helpers. If it never happens, at least we'll have all NAND related support in a single directory and not spread over the drivers/mtd/ directory. Signed-off-by: Boris Brezillon <boris.brezillon@bootlin.com>
