2010-03-19cfq-iosched: fix a kbuild regressionShaohua Li
Alex Shi reported a kbuild regression which is about 10% performance lost. He bisected to this commit: 3dde36ddea3e07dd025c4c1ba47edec91606fec0. The reason is cfqq_close() can't find close cooperator. Restoring cfq_rq_close()'s threshold to original value makes the regression go away. Since for_preempt parameter isn't used anymore, this patch deletes it.

2010-03-15block: Fix overrun in lcm() and move it to libMartin K. Petersen
lcm() was defined to take integer-sized arguments. The supplied arguments are multiplied, however, causing us to overflow given sufficiently large input. That in turn led to incorrect optimal I/O size reporting in some cases (RAID over RAID). Switch lcm() over to unsigned long similar to gcd() and move the function from blk-settings.c to lib.

2010-03-11drbd: fix al-to-on-disk-bitmap for 4k logical_block_sizeLars Ellenberg
Up to now, applying the in-core activity-log to the on-disk bitmap did not care for logical_block_size. On logical_block_size != 512 byte, this very likely results in misalligned block access and spurious "io errors". We now simply always submit aligned whole 4k blocks, fixing this for logical block sizes of 512, 1024, 2048 and 4096. For even larger logical block sizes, this won't work. But I'm not aware of devices with such properties being available. Signed-off-by: Philipp Reisner <philipp.reisner@linbit.com> Signed-off-by: Lars Ellenberg <lars.ellenberg@linbit.com>

Fixes a race and potential kernel panic if e.g. the worker was just about to send a few P_RS_IS_IN_SYNC via the meta socket for checksum based resync, while the receiver destroys the sockets in drbd_disconnect.

2010-03-11fix unit of rs_same_csums accountingLars Ellenberg
Depending on resync request size, we need to account for more than one bit. Impact: cosmetic If SyncTarget reported correctly 100% equal checksums, the SyncSource usually reported 12% equal checksums instead, because it only counted requests, we typically do 32k resync requests, and the bitmap granularity is still 4k.

2010-03-07i2c: Add support for Xilinx XPS IIC Bus InterfaceRichard Röjfors
This patch adds support for the Xilinx XPS IIC Bus Interface. The driver uses the dynamic mode, supporting to put several I2C messages in the FIFO to reduce the number of interrupts. It has the same feature as ocores, it can be passed a list of devices that will be added when the bus is probed.

2010-03-07i2c: omap: Add support for 16-bit registersCory Maccarrone
The current i2c-omap driver is set up for 32-bit registers, which corresponds to most OMAP devices. However, OMAP730/850 based devices use a 16-bit register size. This change modifies the driver to perform a runtime CPU type check to determine the register sizes, and uses a bit shift of either 1 or 2 bits to compute the proper register sizes for all registers.

2010-03-07i2c-pnx: fix setting start/stop conditionLuotao Fu
The start/stop condtions are set in different places repetedly in the i2c-pnx driver. Beside in i2c_pnx_start and i2c_pnx_stop the start/stop bit are also set during the transfer of a i2c message in the master_xmit/rcv calls. This is wrong since we can't set the start/stop condition during the transaction of a single message any way. As a matter of fact, the driver will sometimes set both the start and the stop bits at one time. This can be easily reproduced by sending a simple read request like e.g struct i2c_msg msgs[] = { { addr, 0, 1, buf }, { addr, I2C_M_RD, offset, buf } }; While processing the first message the i2c_pnx_master_xmit will set both the start_bit and the stop_bit, which will eventually confuse the slave. Fixed by remove setting start/stop condition from the transmit routines. Signed-off-by: Luotao Fu <l.fu@pengutronix.de> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
