2016-12-01mtd: Allocate bdi objects dynamicallySteve Longerbeam1-12/+18
The MTD backing dev info objects mtd_bdi was statically allocated. So when MTD is built as a loadable module, this object fall in the vmalloc address space. The problem with that, is that the BDI APIs use wake_up_bit(), which calls virt_to_page() to retrieve the memory zone of the page containing the wait_queue to wake up, and virt_to_page() is not valid for vmalloc or highmem addresses. Fix this by allocating the BDI objects dynamically with kmalloc. The objects now fall in the logical address space so that BDI APIs will work in all cases (mtd builtin or module).

2016-11-23mtd: spi-nor: fix spansion quad enableJoël Esponde1-0/+7
With the S25FL127S nor flash part, each writing to the configuration register takes hundreds of ms. During that time, no more accesses to the flash should be done (even reads). This commit adds a wait loop after the register writing until the flash finishes its work. This issue could make rootfs mounting fail when the latter was done too much closely to this quad enable bit setting step. And in this case, a driver as UBIFS may try to recover the filesystem and may broke it completely.
