2012-05-22Merge tag 'driver-core-3.5-rc1' of ↵Linus Torvalds1-1/+3
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core updates from Greg Kroah-Hartman: "Here's the driver core, and other driver subsystems, pull request for the 3.5-rc1 merge window. Outside of a few minor driver core changes, we ended up with the following different subsystem and core changes as well, due to interdependancies on the driver core: - hyperv driver updates - drivers/memory being created and some drivers moved into it - extcon driver subsystem created out of the old Android staging switch driver code - dynamic debug updates - printk rework, and /dev/kmsg changes All of this has been tested in the linux-next releases for a few weeks with no reported problems. Signed-off-by: Greg Kroah-Hartman <[email protected]>" Fix up conflicts in drivers/extcon/extcon-max8997.c where git noticed that a patch to the deleted drivers/misc/max8997-muic.c driver needs to be applied to this one. * tag 'driver-core-3.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (90 commits) uio_pdrv_genirq: get irq through platform resource if not set otherwise memory: tegra{20,30}-mc: Remove empty *_remove() printk() - isolate KERN_CONT users from ordinary complete lines sysfs: get rid of some lockdep false positives Drivers: hv: util: Properly handle version negotiations.

2012-05-14Drivers: hv: util: Properly handle version negotiations.K. Y. Srinivasan1-1/+3
The current version negotiation code is not "future proof". Fix this by allowing each service the flexibility to either specify the highest version it can support or it can support the highest version number the host is offering. Signed-off-by: K. Y.

2012-04-03net/hyperv: Add flow control based on hi/low watermarkHaiyang Zhang1-0/+27
In the existing code, we only stop queue when the ringbuffer is full, so the current packet has to be dropped or retried from upper layer. This patch stops the tx queue when available ringbuffer is below the low watermark. So the ringbuffer still has small amount of space available for the current packet. This will reduce the overhead of retries on sending. Signed-off-by: Haiyang Zhang <[email protected]> Reviewed-by: K. Y. Srinivasan <[email protected]> Signed-off-by: David S.

2012-03-16Drivers: hv: Support the newly introduced KVP messages in the driverK. Y. Srinivasan1-0/+2
Support the newly defined KVP message types. It turns out that the host pushes a set of standard key value pairs as soon as the guest opens the KVP channel. Since we cannot handle these tuples until the user level daemon loads up, defer reading the KVP channel until the user level daemon is launched. Signed-off-by: K. Y.

2011-10-11hv: remove free_channel() from hyperv.hGreg Kroah-Hartman1-2/+0
