Make nandsim use GFP_NOFS when allocating memory, because it might be used by a file-system (e.g. UBIFS2) which means, if we are short of memory, we may deadlock. Indee, UBIFS is holding a lock, writes to the media, reaches this place in NANDsim, kmalloc does not find the requested amount of RAM, calls memory shrinker, which decides to writeback inodes, calls FS, and it deadlocks on the lock which is already being held. Below is the UBIFS backtrace which demonstrates that: [<c03717dc>] __mutex_lock_slowpath+0xc8/0x2e6 [<c0371a16>] mutex_lock+0x1c/0x1f [<f8b9d076>] reserve_space+0x3d/0xa9 [ubifs] [<f8b9d1bd>] make_one_reservation+0x2b/0x86 [ubifs] [<f8b9d3fc>] ubifs_jrn_write_block+0xda/0x12f [ubifs] [<f8b9ff3a>] ubifs_writepage+0x11d/0x1ec [ubifs] [<c015d6ab>] shrink_inactive_list+0x7fa/0x969 [<c015d8c8>] shrink_zone+0xae/0x10c [<c015e3b4>] try_to_free_pages+0x159/0x251 [<c015980a>] __alloc_pages+0x125/0x2f0 [<c016ff6a>] cache_alloc_refill+0x380/0x6ba [<c01703f3>] __kmalloc+0x14f/0x157 [<f885722a>] do_state_action+0xab7/0xc74 [nandsim] [<f885760c>] switch_state+0x225/0x402 [nandsim] [<f8857e7e>] ns_hwcontrol+0x3e2/0x620 [nandsim] [<f8862f53>] nand_command+0x2e/0x1a5 [nand] [<f8861ad8>] nand_write_page+0x4a/0x9a [nand] [<f88617b4>] nand_do_write_ops+0x1cf/0x343 [nand] [<f8861a70>] nand_write+0x88/0xa6 [nand] [<f8850b0e>] part_write+0x72/0x8b [mtd] [<f88e19c5>] ubi_io_write+0x189/0x29c [ubi] [<f88dfb98>] ubi_eba_write_leb+0xb6/0x699 [ubi] [<f88def93>] ubi_leb_write+0xe4/0xe9 [ubi] [<f8ba3b82>] ubifs_wbuf_write_nolock+0x333/0x4c9 [ubifs] [<f8b9d28c>] write_node+0x74/0x8e [ubifs] [<f8b9d422>] ubifs_jrn_write_block+0x100/0x12f [ubifs] [<f8b9ff3a>] ubifs_writepage+0x11d/0x1ec [ubifs] [<c0159e5b>] __writepage+0xb/0x26 [<c015a318>] write_cache_pages+0x203/0x2d9 [<c015a411>] generic_writepages+0x23/0x2d [<c015a452>] do_writepages+0x37/0x39 [<c018e24a>] __writeback_single_inode+0x96/0x399 [<c018e903>] sync_sb_inodes+0x1a3/0x274 [<c018ebf3>] writeback_inodes+0xa6/0xd8 [<c015a9dd>] background_writeout+0x86/0x9e [<c015ae9c>] pdflush+0xfb/0x1b6 [<c01387d7>] kthread+0x37/0x59 [<c0104dc3>] kernel_thread_helper+0x7/0x14 The deadlock is funny because it starts in pdflush/writeback, and comes back to writeback, then deadlocks.

Unlike most stuff on the market the chip inside these two allows raw flash access and doesn't implement and FTL, leaving that functionality to the device driver. Raw flash access in a cheap USB cardreader! An MTD test device one can attach to a PC! What a deal! The command set of the chip is not documented, so information was obtained from the existing mass-storage driver (drivers/usb/storage/alauda.c), its documentation (http://alauda.sourceforge.net/wikka.php?wakka=BulkCommandReference), additional reverse engineering and comparison with a vendor driver for a related chip (http://www.ratocsystems.com/english/download/driver/linux/sma03u.html).

This reverts commit 340ea370. It's not needed given the other m25p80 patch (which now handles at26 "dataflash" as well as most other standard SPI flash chips), and requires a controller driver that won't be merged upstream (supplanted by drivers/spi/atmel_spi.c) ... the submitter of that at91_dataflash26.c driver concurred.

So their multiplication for larger values causes integer overflows. Typecasting them solves the problem.
