2012-11-17gpio-mcp23s08: Build I2C support even when CONFIG_I2C=mDaniel M. Weeks
The driver has both SPI and I2C pieces. The appropriate pieces are built based on whether SPI and/or I2C is/are enabled. However, it was only checking if I2C was built-in, never if it was built as a module. This patch checks for either since building both this driver and I2C as modules is possible.

2012-11-15s390/3215: fix tty close handlingHeiko Carstens
The 3215 console always has the RAW3215_FIXED flag set, which causes raw3215_shutdown() not to wait for outstanding I/O requests if an attached tty gets closed. The flag however can be simply removed, so we can guarantee that all requests belonging to the tty have been processed when the tty is closed. However the tasklet that belongs to the 3215 device may be scheduled even if there is no tty attached anymore, since we have a race between console and tty processing. Thefore unconditional tty_wakekup() in raw3215_wakeup() can cause the following NULL pointer dereference: 3.465368 Unable to handle kernel pointer dereference at virtual kernel address (null) 3.465448 Oops: 0004 #1 SMP 3.465454 Modules linked in: 3.465459 CPU: 1 Not tainted 3.6.0 #1 3.465462 Process swapper/1 (pid: 0, task: 000000003ffa4428, ksp: 000000003ffb7ce0) 3.465466 Krnl PSW : 0404100180000000 0000000000162f86 (__wake_up+0x46/0xb8) 3.465480 R:0 T:1 IO:0 EX:0 Key:0 M:1 W:0 P:0 AS:0 CC:1 PM:0 EA:3 Krnl GPRS: fffffffffffffffe 0000000000000000 0000000000000160 0000000000000001 3.465492 0000000000000001 0000000000000004 0000000000000004 000000000096b490 3.465499 0000000000000001 0000000000000100 0000000000000001 0000000000000001 3.465506 070000003fc87d60 0000000000000160 000000003fc87d68 000000003fc87d00 3.465526 Krnl Code: 0000000000162f76: e3c0f0a80004 lg %r12,168(%r15) 0000000000162f7c: 58000370 l %r0,880 #0000000000162f80: c007ffffffff00 xilf %r0,4294967295 >0000000000162f86: ba102000 cs %r1,%r0,0(%r2) 0000000000162f8a: 1211 ltr %r1,%r1 0000000000162f8c: a774002f brc 7,162fea 0000000000162f90: b904002d lgr %r2,%r13 0000000000162f94: b904003a lgr %r3,%r10 3.465597 Call Trace: 3.465599 (<0400000000000000> 0x400000000000000) 3.465602 <000000000048c77e> raw3215_wakeup+0x2e/0x40 3.465607 <0000000000134d66> tasklet_action+0x96/0x168 3.465612 <000000000013423c> __do_softirq+0xd8/0x21c 3.465615 <0000000000134678> irq_exit+0xa8/0xac 3.465617 <000000000046c232> do_IRQ+0x182/0x248 3.465621 <00000000005c8296> io_return+0x0/0x8 3.465625 <00000000005c7cac> vtime_stop_cpu+0x4c/0xb8 3.465629 (<0000000000194e06> tick_nohz_idle_enter+0x4e/0x74) 3.465633 <0000000000104760> cpu_idle+0x170/0x184 3.465636 <00000000005b5182> smp_start_secondary+0xd6/0xe0 3.465641 <00000000005c86be> restart_int_handler+0x56/0x6c 3.465643 <0000000000000000> 0x0 3.465645 Last Breaking-Event-Address: 3.465647 <0000000000403136> tty_wakeup+0x46/0x98 3.465652 3.465654 Kernel panic - not syncing: Fatal exception in interrupt 01: HCPGIR450W CP entered; disabled wait PSW 00020001 80000000 00000000 0010F63C The easiest solution is simply to check if tty is NULL in the tasklet.

2012-11-15mtd: nand: fix Samsung SLC detection regressionBrian Norris
This patch fixes errors seen in identifying old Samsung SLC, due to the following commits: commit e2d3a35ee427aaba99b6c68a56609ce276c51270 mtd: nand: detect Samsung K9GBG08U0A, K9GAG08U0F ID commit e3b88bd604283ef83ae6e8f53622d5b1ffe9d43a 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 bc86cf7af2ebda88056538e8edff852ee627f76a 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.

2012-11-15mtd: nand: fix Samsung SLC NAND identification regressionBrian Norris
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 e3b88bd604283ef83ae6e8f53622d5b1ffe9d43a mtd: nand: add generic READ ID length calculation functions commit e2d3a35ee427aaba99b6c68a56609ce276c51270 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.

2012-11-14Revert "drivers/net/phy/mdio-bitbang.c: Call mdiobus_unregister before ↵David S. Miller
mdiobus_free" This reverts commit aa731872f7d33dcb8b54dad0cfb82d4e4d195d7e. As pointed out by Ben Hutchings, this change is not correct. mdiobus_unregister() can't be called if the bus isn't registered yet, however this change can result in situations which cause that to happen. Part of the confusion here revolves around the fact that the callers of this module control registration/unregistration, rather than the module itself. Signed-off-by: David S.

2012-11-14net/smsc911x: Fix ready check in cases where WORD_SWAP is neededKamlakant Patel
The chip ready check added by the commit 3ac3546e [Always wait for the chip to be ready] does not work when the register read/write is word swapped. This check has been added before the WORD_SWAP register is programmed, so we need to check for swapped register value as well. Bit 16 is marked as RESERVED in SMSC datasheet, Steve Glendinning <steve@shawell.net> checked with SMSC and wrote: The chip architects have concluded we should be reading PMT_CTRL until we see any of bits 0, 8, 16 or 24 set. Then we should read BYTE_TEST to check the byte order is correct (as we already do). The rationale behind this is that some of the chip variants have word order swapping features too, so the READY bit could actually be in any of the 4 possible locations. The architects have confirmed that if any of these 4 positions is set the chip is ready. The other 3 locations will either never be set or can only go high after READY does (so also indicate the device is ready). This change will check for the READY bit at the 16th position. We do not check the other two cases (bit 8 and 24) since the driver does not support byte-swapped register read/write.

2012-11-14drivers/net: fix tasklet misuse issueXiaotian Feng
In commit 175c0dff, drivers uses tasklet_kill to avoid put disabled tasklet on the tasklet vec. But some of the drivers uses tasklet_init & tasklet_disable in the driver init code, then tasklet_enable when it is opened. This makes tasklet_enable on a killed tasklet and make ksoftirqd crazy then. Normally, drivers should use tasklet_init/tasklet_kill on device open/remove, and use tasklet_disable/tasklet_enable on device suspend/resume.
