Few devices like H27UBG8T2CTR have a writesize/oobsize of 8KB/640B. This means that the maximum oobsize has gone up to 640 bytes and consequently the maximum ecc placement locations have also gone up to 640.

Use relaxed variants of readl/writel accessors. readl/writel io accessors use explicit dsb instruction which causes stalls in the processor core resulting several cycles of delay for each access Use relaxed variants where ever possible.

Since the introduction of nand_create_default_bbt_descr() (now known as nand_create_badblock_pattern()) in commit 58373ff0 nand_chip.badblock_pattern will be dynamically calculated to the same 1-byte-length pattern that is required by fsl_elbc_nand. This custom badblock_pattern is no longer needed, then, and its removal may help facilitate further nand_bbt.c/nand_base.c cleanup in the future (one down, many to go?)

Simply 'parse_cmdline_partitions': the outer loop iterating over 'partitions' is actually a search loop, it does not execute the inner loop for each partition, only for the matched partition. Let's break when search is successful, and move all inner code (relevant only for the matched partition) outside of the outer loop. Resulting code is much more readable, and makes the indent level sane. Signed-off-by: Shmulik Ladkani <shmulik.ladkani@gmail.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

This patch fixes errors seen in identifying old Samsung SLC, due to the following commits: commit e2d3a35e mtd: nand: detect Samsung K9GBG08U0A, K9GAG08U0F ID commit e3b88bd6 mtd: nand: add generic READ ID length calculation functions Some Samsung NAND with "5-byte" ID really appear to have 6-byte IDs, with wraparound like: Samsung K9K8G08U0D ec d3 51 95 58 ec ec d3 Samsung K9F1G08U0C ec f1 00 95 40 ec ec f1 Samsung K9F2G08U0B ec da 10 95 44 00 ec da This bad wraparound makes it hard to reliably detect the difference between Samsung SLC with 5-byte ID and Samsung SLC with 6-byte ID. The fix is to, for now, only use the new Samsung table for MLC. We cannot support the new SLC (K9FAG08U0M) until Samsung gives better ID decode information. Note that this applies in addition to the previous regression fix: commit bc86cf7a mtd: nand: fix Samsung SLC NAND identification regression Together, these patches completely restore the previous detection behavior so that we cannot see any more regressions in Samsung SLC NAND (finger crossed). With luck, I can get a hold of a Samsung representative and stop having to cross my fingers eventually.

A combination of the following two commits caused a regression in 3.7-rc1 when identifying some Samsung NAND, so that some previously working NAND were no longer detected properly: commit e3b88bd6 mtd: nand: add generic READ ID length calculation functions commit e2d3a35e mtd: nand: detect Samsung K9GBG08U0A, K9GAG08U0F ID Particularly, a regression was seen on Samsung K9F2G08U0B, with the following full 8-byte READ ID string: ec da 10 95 44 00 ec da The basic problem is that Samsung manufactures both SLC and MLC NAND that use a non-standard decoding table for deriving information from their IDs. I have heuristically determined that all the chips that use the new table have ID strings which wrap around after the 6th byte. Unfortunately, I overlooked the fact that some older Samsung SLC (which use a different decoding table) have "5 byte ID strings" which also wrap around after the 6th byte. This patch re-introduces a distinction between these old and new Samsung NAND by checking that the 6th byte is non-zero, allowing both old and new Samsung NAND to be detected properly.

jffs2_write_begin() first acquires the page lock, then f->sem. This causes an AB-BA deadlock with jffs2_garbage_collect_live(), which first acquires f->sem, then the page lock: jffs2_garbage_collect_live mutex_lock(&f->sem) (A) jffs2_garbage_collect_dnode jffs2_gc_fetch_page read_cache_page_async do_read_cache_page lock_page(page) (B) jffs2_write_begin grab_cache_page_write_begin find_lock_page lock_page(page) (B) mutex_lock(&f->sem) (A) We fix this by restructuring jffs2_write_begin() to take f->sem before the page lock. However, we make sure that f->sem is not held when calling jffs2_reserve_space(), as this is not permitted by the locking rules. The deadlock above was observed multiple times on an SoC with a dual ARMv7 (Cortex-A9), running the long-term 3.4.11 kernel; it occurred when using scp to copy files from a host system to the ARM target system. The fix was heavily tested on the same target system.

Pull i2c embedded fixes from Wolfram Sang: "Two patches are usual stuff. The bigger patch is needed to correct a wrong decision made in this merge window. We hoped to get the PIOQUEUE mode in the mxs driver working with DMA, but it turned out to be too broken (leading to data loss), so we now think it is best to remove it entirely and work only with DMA now. The patch should be in 3.7.

When sending data into a tcp socket in repair state we should check for the amount of data being 0 explicitly. Otherwise we'll have an skb with seq == end_seq in rcv queue, but tcp doesn't expect this to happen (in particular a warn_on in tcp_recvmsg shoots).

When creating an L2TPv3 Ethernet session, if register_netdev() should fail for any reason (for example, automatic naming for "l2tpeth%d" interfaces hits the 32k-interface limit), the netdev is freed in the error path. However, the l2tp_eth_sess structure's dev pointer is left uncleared, and this results in l2tp_eth_delete() then attempting to unregister the same netdev later in the session teardown. This results in an oops. To avoid this, clear the session dev pointer in the error path. Signed-off-by: Tom Parkin <tparkin@katalix.com> Signed-off-by: David S. Miller <davem@davemloft.net>
