2009-05-07sh: Integrate the SH-5 onchip_remap() more coherently.Paul Mundt
Presently this is special-cased for early initialization. While there are situations where these static early initializations are still necessary, with minor changes it is possible to use this for the regular ioremap implementation as well. This allows us to kill off the special-casing for the remap completely and to start tidying up all of the SH-5 special-casing in drivers. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2009-05-03sh: Consolidate MTU2/CMT/TMU timer platform data.Paul Mundt
All of the SH timers use a roughly identical structure for platform data, which presently is broken out for each block. Consolidate all of these definitions, as there is no reason for them to be broken out in the first place. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-03clocksource: SuperH TMU Timer driverMagnus Damm
This patch adds a TMU driver for the SuperH architecture. The TMU driver is a platform driver with early platform support to allow using a TMU channel as clockevent or clocksource during system bootup or later. Clocksource or clockevent can be selected. Both periodic and oneshot clockevents are supported. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-05-03clocksource: SuperH MTU2 Timer driverMagnus Damm
This patch adds a MTU2 driver for the SuperH architecture. The MTU2 driver is a platform driver with early platform support to allow using a MTU2 channel as only clockevent during system bootup. Clocksource on sh2a is currently unsupported due to code generation issues with 64-bit math, so at this point only periodic clockevent support is in place.

A regression was introduced in hg changeset 33810c734a0d, which resulted in a kernel panic whenever the device was disconnected from USB. The call to 4l2_device_register() was overwriting the pointer for usb_set_intfdata(), so when au0828_usb_disconnect() was called, the usb_get_intfdata() returned a pointer to the v4l2_device instead of the au0828_dev structure.

2009-04-29V4L/DVB (11561a): move media after i2cGuennadi Liakhovetski
Currently drivers/media drivers are linked very early - directly after base, block, misc, and mfd and before ata, scsi, ide, input, firewire, usb, and i2c. This breaks static build of video4linux drivers, that use generic CPU i2c adapter drivers and the v4l2-subdev subsystem, because during video4linux probing the v4l2-subdev core requires a struct i2c_adapter context, which cannot be satisfied before the i2c subsystem is initialised. Moving drivers/media after drivers/i2c fixes this problem. The best way to trigger action is by submitting a patch:-) So, let's see what comes out of it - on the one hand I don't see any reason why media has to be linked this early, and nobody was able to give me one yesterday as this problem has been discussed on linux-media, OTOH, maybe indeed it would be better to move i2c the whole way up above media, but that'd be much bigger of a change, I think. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Acked-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2009-04-28e100: do not go D3 in shutdown unless system is powering offThadeu Lima de Souza Cascardo
After experimenting with kexec with the last merges after 2.6.29, I've had some problems when probing e100. It would not read the eeprom. After some bisects, I realized this has been like that since forever (at least 2.6.18). The problem is that shutdown is doing the same thing that suspend does and puts the device in D3 state. I couldn't find a way to get the device back to a sane state in the probe function. So, based on some similar patches from Rafael J. Wysocki for e1000, e1000e, and ixgbe, I wrote this one for e100.

2009-04-28hd: fix lockingTejun Heo
hd dance around local irq and HD_IRQ enable without achieving much. It ends up transferring data from irq handler with both local irq and HD_IRQ disabled. The only place it actually does something is while transferring the first block of a request which it does with HD_IRQ disabled but local irq enabled. Unfortunately, the dancing is horribly broken from locking POV. IRQ and timeout handlers access block queue without grabbing the queue lock and running the driver in SMP configuration crashes the whole machine pretty quickly. Remove meaningless irq enable/disable dancing and add proper locking in issue, irq and timeout paths. Signed-off-by: Tejun Heo <tj@kernel.org>

2009-04-28regulator: Fix default constraints for fixed voltage regulatorsMark Brown
Default voltage constraints were being provided for fixed voltage regulator where board constraints were not provided but these constraints used INT_MIN as the default minimum voltage which is not a valid value since it is less than zero. Use 1uV instead. Also set the default values we set in the constraints themselves since otherwise the max_uV constraint we determine will not be stored in the actual constraint strucutre and will therefore not be used.

2009-04-28regulator core: fix double-free in regulator_register() error pathPaul Walmsley
During regulator registration, any error after device_register() will cause a double-free on the struct regulator_dev 'rdev'. The bug is in drivers/regulator/core.c:regulator_register(): ... scrub: device_unregister(&rdev->dev); clean: kfree(rdev); <--- rdev = ERR_PTR(ret); goto out; ... device_unregister() calls regulator_dev_release() which frees rdev. The subsequent kfree corrupts memory and causes some OMAP3 systems to oops on boot in regulator_get(). Applies against 2.6.30-rc3.

2009-04-27RDMA/nes: Fix hang issues for large cluster dynamic connectionsFaisal Latif
Running large cluster setup, we are hanging after many hours of testing. Fixing this required going over the code and making sure the rexmit entry was properly removed based on the cm_node's state and packet received. Also when receiving a FIN packet, check seq# and make sure there were no errors before calling handle_fin(). Following are the changes done in nes_cm.c: * handle_ack_pkt() needs to return error value, so in case of error, handle_fin() is not called. Some cleanup done while going over the code. * handle_rst_pkt(), handling of cm_node's NES_CM_STATE_LAST_ACK is missing. * process_packet(), in case of FIN only packet is received, call check_seq() before processing. * in handle_fin_pkt(), we are calling cleanup_retrans_entry() for all conditions, even if the packets need to be dropped.
