* x86, amd-nb: Rename CPU PCI id define for F4Borislav Petkov2011-03-311-1/+1
| | | | | | | | | | | With increasing number of PCI function ids, add the PCI function id in the define name instead of its symbolic name in the BKDG for more clarity. This renames function 4 define.

Now that we no longer call nfs_clear_request() until the nfs_page is being freed, we know that we are always holding a reference to the nfs_open_context, which again holds a reference to the path, and so the inode cannot be freed until the last nfs_page has been removed from the radix tree and freed.

However, it did not have suspend-finish that pairs with suspend-prepare and the regulator core has assumed that the regulator devices and their drivers support autonomous recover at resume. This patch adds regulator_suspend_finish that pairs with the previously-existed regulator_suspend_prepare. The function regulator_suspend_finish turns on the regulators that have always_on set or positive use_count so that we can reset the regulator states appropriately at resume. In regulator_suspend_finish, if has_full_constraints, it disables unnecessary regulators.

This can cause all sort of interesting things ranging from to garbled sound to lockups on various architectures. I've observed that usb-audio is broken on powerpc 4xx for example because of that. Also remove the now unused snd_pcm_lib_mmap_noncached(). It's an arch business to know when to use uncached mappings, there's already hacks for MIPS inside snd_pcm_default_mmap() and other archs are supposed to use dma_mmap_coherent().

Please note that Fuel-Gauge-related IRQs are not implemented in this initial release. The fuel gauge module in MAX8997 is identical to MAX17042, which is already in Linux kernel. In order to use the already-existing MAX17042 driver for fuel gauge module in MAX8997, the main interrupt handler of MAX8997 should relay related interrupts to MAX17042 driver. However, in order to do this, we need to modify MAX17042 driver as well because MAX17042 driver does not have any interrupt handlers for now. We are not going to implement this in this initial release as it is not crucial in basic operations of MAX8997.

The former was called by an mfd client, and registered both a platform driver and device. The latter is called by an mfd driver, and registers only a platform device. The downside of this is that mfd drivers need to be modified whenever new clients are added that share a cell; the upside is that it fits Linux's driver model better. It's also simpler. This also converts cs5535-mfd/olpc-xo1 from the old API. cs5535-mfd now creates the olpc-xo1-{acpi,pms} devices, while olpc-xo1 binds to them via platform drivers.

NOTE! This merge commit was created to fix compilation error. The block tree was merged upstream and removed the 'elv_queue_empty()' function which the new 'mtdswap' driver is using. So a simple merge of the mtd tree with upstream does not compile. And the mtd tree has already be published, so re-basing it is not an option. To fix this unfortunate situation, I had to merge upstream into the mtd-2.6.git tree without committing, put the fixup patch on top of this, and then commit this. The result is that we do not have commits which do not compile. In other words, this merge commit "merges" 3 things: the MTD tree, the upstream tree, and the fixup patch.

It does so by adding a new ecc mode (NAND_ECC_SOFT_BCH) for use by board drivers, and a new Kconfig option to enable BCH support. It relies on the generic BCH library introduced in a previous patch. When a board driver uses mode NAND_ECC_SOFT_BCH, it should also set fields chip->ecc.size and chip->ecc.bytes to select BCH ecc data size and required error correction capability. See nand_bch_init() documentation for details. It has been tested on the following platforms using mtd-utils, UBI and UBIFS: x86 (with nandsim), arm926ejs.

Binary BCH (Bose-Chaudhuri-Hocquenghem) codes are widely used to correct errors in NAND flash devices requiring more than 1-bit ecc correction; they are generally better suited for NAND flash than RS codes because NAND bit errors do not occur in bursts. Latest SLC NAND devices typically require at least 4-bit ecc protection per 512 bytes block. This library provides software encoding/decoding, but may also be used with ASIC/SoC hardware BCH engines to perform error correction. It is being currently used for this purpose on an OMAP3630 board (4bit/8bit HW BCH). It has also been used to decode raw dumps of NAND devices with on-die BCH ecc engines (e.g. Micron 4bit ecc SLC devices). Latest NAND devices (including SLC) can exhibit high error rates (typically a dozen or more bitflips per hour during stress tests); in order to minimize the performance impact of error correction, this library implements recently developed algorithms for fast polynomial root finding (see bch.c header for details) instead of the traditional exhaustive Chien root search; a few performance figures are provided below: Platform: arm926ejs @ 468 MHz, 32 KiB icache, 16 KiB dcache BCH ecc : 4-bit per 512 bytes Encoding average throughput: 250 Mbits/s Error correction time (compared with Chien search): average worst average (Chien) worst (Chien) ---------------------------------------------------------- 1 bit 8.5 µs 11 µs 200 µs 383 µs 2 bit 9.7 µs 12.5 µs 477 µs 728 µs 3 bit 18.1 µs 20.6 µs 758 µs 1010 µs 4 bit 19.5 µs 23 µs 1028 µs 1280 µs In the above figures, "worst" is meant in terms of error pattern, not in terms of cache miss / page faults effects (not taken into account here). The library has been extensively tested on the following platforms: x86, x86_64, arm926ejs, omap3630, qemu-ppc64, qemu-mips.
