* cache invalidation error for buffered writeMassimo Cirillo2008-01-111-2/+5
| | | | | | | | | | | | | | | | The bug causes corruptions of data read from flash. The original code performs cache invalidation from "adr" to "adr + len" in do_write_buffer(). Since len and adr could be updated in the code before invalidation - it causes improper setting of cache invalidation regions.

* Reinstate lost flush_ioremap_region() fix to pxa2xx-flash driverLinus Torvalds2007-10-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | Commit 90833fdab89da02fc0276224167f0a42e5176f41 ("[ARM] 4554/1: replace consistent_sync() with flush_ioremap_region()") introduced a new "flush_ioremap_region()" function to be used by the MTD mainstone-flash and lubbock-flash drivers to fix a regression from around 2.6.18. Those drivers were independently merged into a single driver by Todd Poynor in commit e644f7d6289456657996df4192de76c5d0a9f9c7 ("[MTD] MAPS: Merge Lubbock and Mainstone drivers into common PXA2xx driver") Later, those two commits were merged into the main MTD tree by commit b160292cc216a50fd0cd386b0bda2cd48352c73b ("Merge Linux 2.6.23") by David Woodhouse, but in that merge, the fix to use flush_iomap_region() got lost (as it was to files that now no longer existed). This reinstates the fix in the new driver.

| * UBI: fix atomic LEB change problemsArtem Bityutskiy2007-10-142-21/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the UBI device is nearly full, i.e. all LEBs are mapped, we have only one spare LEB left - the one we reserved for WL purposes. Well, I do not count the LEBs which were reserved for bad PEB handling - suppose NOR flash for simplicity. If an "atomic LEB change operation" is run, and the WL unit is moving a LEB, we have no spare LEBs to finish the operation and fail, which is not good. Moreover, if there are 2 or more simultanious "atomic LEB change" requests, only one of them has chances to succeed, the other will fail with -ENOSPC. Not good either. This patch does 2 things: 1. Reserves one PEB for the "atomic LEB change" operation. 2. Serealize the operations so that only on of them may run at a time (by means of a mutex).

| | | | | | | | | | | | | | | | | | | | | | Similar reason as in case of the previous patch: it causes deadlocks if a filesystem with writeback support works on top of UBI. So pre-allocate needed buffers when attaching MTD device. We also need mutexes to protect the buffers, but they do not cause much contantion because they are used in recovery, torture, and WL copy routines, which are called seldom.

| | | | | | | | | | | | | | | | | | | | | | | | | | I can't find anything guaranteeing that 'ubi_num' cannot be <0 in drivers/mtd/ubi/kapi.c::ubi_open_volume(), and in fact the code even tests for that and errors out if so. Unfortunately the test for "ubi_num < 0" happens after we've already used 'ubi_num' as an array index - bad thing to do if it is negative. This patch moves the test earlier in the function and then moves the indexing using that variable after the check.

The fact that the flash chips must be physically direct mapped is a constrant, but doesn't really say anything about the actual purpose of this driver, which is to instantiate MTD devices based on information from the device tree. Therefore the physmap name is replaced everywhere within the file with "of_flash". The file itself and the Kconfig option is not renamed for now (so that the diff is actually a diff).
