2011-11-15RS485: fix inconsistencies in the meaning of some variablesClaudio Scordino
The crisv10.c and the atmel_serial.c serial drivers intepret the fields of the serial_rs485 structure in a different way. In particular, crisv10.c uses SER_RS485_RTS_AFTER_SEND and SER_RS485_RTS_ON_SEND for the voltage of the RTS pin; atmel_serial.c, instead, uses these values to know if a delay must be set before and after sending. This patch makes the usage of these variables consistent across all drivers and fixes the Documentation as well. From now on, SER_RS485_RTS_AFTER_SEND and SER_RS485_RTS_ON_SEND will be used to set the voltage of the RTS pin (as in the crisv10.c driver); the delay will be understood by looking only at the value of delay_rts_before_send and delay_rts_after_send.

2011-11-15pch_uart: Fix DMA resource leak issueTomoya MORINAGA
Changing UART mode PIO->DMA->PIO->DMA like below, pch_uart driver can't get DMA channel resource. setserial /dev/ttyPCH0 ^low_latency setserial /dev/ttyPCH0 low_latency CAUSE: Changing mode using setserial command, ".startup" function which gets DMA channel is called before ".verify_port" function which sets dma-flag(use_dma/use_dma_flag) as 1. PIO->DMA .startup: Since dma-flag is 0, DMA channel is not requested. .verify_port: dma-flag is set as 1. .shutdown: N/A DMA->PIO .startup: Since dma-flag is 1, DMA channel is requested. .verify_port: dma-flag is set as 0. .shutdown: Since dma-flag is 0, DMA channel is not released. This means DMA channel resource leak occurs. Next time, this driver can't get DMA channel resource forever. MODIFICATION: Currently, when release DMA channel resource, this driver checks dma-flag. However, this specification occurs the above issue. This driver must check whether dma_request_channel is executed or not. The values are saved in private data variable "chan_tx/chan_tx". These variables mean if the value is NULL, DMA channel is not requested, if not NULL, DMA channel is requested. This patch fixes the issue.

2011-11-15tty/serial: Prevent drop of DCD on suspend for Tegra UARTsDoug Anderson
On Tegra UARTs (except UART1), the DTR / DCD / DSR lines are not externally accessible. Instead, the DTR line internally appears to be looped back to be the input to the DCD and DSR lines. The net effect of this is that when we drop DTR (like when we suspend), we'll see DCD drop too. ...and when we see DCD drop, we treat that as a hangup. In order to prevent this hangup from occurring at every sleep, we need to force DTR to remain high on Tegra UARTs. This patch uses the mcr_mask / mcr_force fields, which were originally added for the kludge ALPHA_KLUDGE_MCR. Using these fields does not prevent us from removing ALPHA_KLUDGE_MCR--we can just remove the "if" tests I have added and always init mcr_mask / mcr_force from the serial8250_config. NOTE: If we have people that are using UARTA on a Tegra and need to control DTR, we'll need to either add a separate port type for UARTA or we'll need to add some tegra-specific code to detect whether the DTR needs to be left high.

2011-11-15tty: hvc_dcc: Fix duplicate character inputsStephen Boyd
Reading from the DCC grabs a character from the buffer and clears the status bit. Since this is a context-changing operation, instructions following the character read that rely on the status bit being accurate need to be synchronized with an ISB. In this case, the status bit check needs to execute after the character read otherwise we run the risk of reading the character and checking the status bit before the read can clear the status bit in the first place. When this happens, the user will see the same character they typed twice, instead of once. Add an ISB after the read and the write, so that the status check is synchronized with the read/write operations.

2011-11-15Btrfs: fix tree corruption after multi-thread snapshots and inode_cache flushLiu Bo
The btrfs snapshotting code requires that once a root has been snapshotted, we don't change it during a commit. But there are two cases to lead to tree corruptions: 1) multi-thread snapshots can commit serveral snapshots in a transaction, and this may change the src root when processing the following pending snapshots, which lead to the former snapshots corruptions; 2) the free inode cache was changing the roots when it root the cache, which lead to corruptions. This fixes things by making sure we force COW the block after we create a snapshot during commiting a transaction, then any changes to the roots will result in COW, and we get all the fs roots and snapshot roots to be consistent.

2011-11-14sparc: Fix handling of orig_i0 wrt. debugging when restarting syscalls.David S. Miller
Although we provide a proper way for a debugger to control whether syscall restart occurs, we run into problems because orig_i0 is not saved and restored properly. Luckily we can solve this problem without having to make debuggers aware of the issue. Across system calls, several registers are considered volatile and can be safely clobbered. Therefore we use the pt_regs save area of one of those registers, %g2, as a place to save and restore orig_i0. Debuggers transparently will do the right thing because they save and restore this register already. Signed-off-by: David S. Miller <davem@davemloft.net>

2011-11-14usb-storage: Accept 8020i-protocol commands longer than 12 bytesAlan Stern
The 8020i protocol (also 8070i and QIC-157) uses 12-byte commands; shorter commands must be padded. Simon Detheridge reports that his 3-TB USB disk drive claims to use the 8020i protocol (which is normally meant for ATAPI devices like CD drives), and because of its large size, the disk drive requires the use of 16-byte commands. However the usb_stor_pad12_command() routine in usb-storage always sets the command length to 12, making the drive impossible to use. Since the SFF-8020i specification allows for 16-byte commands in future extensions, we may as well accept them. This patch (as1490) changes usb_stor_pad12_command() to leave commands larger than 12 bytes alone rather than truncating them.
