2010-08-20mtd: nand: Fix probe of Samsung NAND chipsTilman Sauerbeck
Apparently, the check for a 6-byte ID string introduced by commit 426c457a3216fac74e3d44dd39729b0689f4c7ab ("mtd: nand: extend NAND flash detection to new MLC chips") is NOT sufficient to determine whether or not a Samsung chip uses their new MLC detection scheme or the old, standard scheme. This adds a condition to check cell type.

2010-08-19mtd: nand: Fix regression in BBM detectionBrian Norris
Commit c7b28e25cb9beb943aead770ff14551b55fa8c79 ("mtd: nand: refactor BB marker detection") caused a regression in detection of factory-set bad block markers, especially for certain small-page NAND. This fix removes some unneeded constraints on using NAND_SMALL_BADBLOCK_POS, making the detection code more correct. This regression can be seen, for example, in Hynix HY27US081G1M and similar.

2010-08-18pxa3xx: fix ns2cycle equationAxel Lin
Test on a PXA310 platform with Samsung K9F2G08X0B NAND flash, with tCH=5 and clk is 156MHz, ns2cycle(5, 156000000) returns -1. ns2cycle returns negtive value will break NDTR0_tXX macros. After checking the commit log, I found the problem is introduced by commit 5b0d4d7c8a67c5ba3d35e6ceb0c5530cc6846db7 "[MTD] [NAND] pxa3xx: convert from ns to clock ticks more accurately" To get num of clock cycles, we use below equation: num of clock cycles = time (ns) / one clock cycle (ns) + 1 We need to add 1 cycle here because integer division will truncate the result. It is possible the developers set the Min values in SPEC for timing settings. Thus the truncate may cause problem, and it is safe to add an extra cycle here. The various fields in NDTR{01} are in units of clock ticks minus one, thus we should subtract 1 cycle then. Thus the correct equation should be: num of clock cycles = time (ns) / one clock cycle (ns) + 1 - 1 = time (ns) / one clock cycle (ns) Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Lei Wen <leiwen@marvell.com> Acked-by: Eric Miao <eric.y.miao@gmail.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com> Cc: stable@kernel.org

2010-08-12mtd/m25p80: fix test for end of loopDan Carpenter
"plat_id" is always non-NULL here. There is a zero element on the end of the m25p_ids[] array and if we hit the end of the loop then plat_id points to that. This would lead to a NULL pointer dereference later on in the function.

2010-08-12mtd/m25p80: retlen is never NULLDan Carpenter
This is just a cleanup, it doesn't fix any bugs. These functions all check retlen inconsistently and it generates a warning in Smatch (http://smatch.sf.net). If retlen were ever NULL it would cause an oops and the code has been this way since 2006 so someone would have complained. Also I looked at other places that implemented the mtd read and write functions and they dereference retlen without checking. I removed the checks.

In mtd->write, Denali controller will use MODE_11 mode to read NAND flash status, then return back to MODE_1O mode to do page write. Here comes a bug for this kind of using, sometimes controller will not write data to NAND and just return a good interrupt to tell driver writing work is done. The data in this page is all 0xff and this page can not be written again. The reason is unknow. So read Denali controller register WRITE_PROTECT to get NAND status instead.

2010-08-08mtd-physmap: add support users can assign the probe type in board filesBarry Song
There are three reasons to add this support: 1. users probably know the interface type of their flashs, then probe can be faster if they give the right type in platform data since wrong types will not be detected. 2. sometimes, detecting can cause destory to system. For example, for kernel XIP, detecting can cause NOR enter a mode instructions can not be fetched right, which will make kernel crash. 3. For a new probe which is not listed in the rom_probe_types, if users assign it in board files, physmap can still probe it.

2010-08-07block: push down BKL into .open and .releaseArnd Bergmann
The open and release block_device_operations are currently called with the BKL held. In order to change that, we must first make sure that all drivers that currently rely on this have no regressions. This blindly pushes the BKL into all .open and .release operations for all block drivers to prepare for the next step. The drivers can subsequently replace the BKL with their own locks or remove it completely when it can be shown that it is not needed. The functions blkdev_get and blkdev_put are the only remaining users of the big kernel lock in the block layer, besides a few uses in the ioctl code, none of which need to serialize with blkdev_{get,put}. Most of these two functions is also under the protection of bdev->bd_mutex, including the actual calls to ->open and ->release, and the common code does not access any global data structures that need the BKL.
