* usbcore: small changes to hub driver's suspend methodAlan Stern2007-02-161-15/+10
| | | | | | | | | | | | | | | This patch (as847) makes some small changes to the hub driver's suspend method: For root hubs, the status URB should be unlinked and other activity stopped _before_ the bus_suspend method is called. The test for hdev->bus being NULL has been removed, since it can never succeed. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* USB: add flow control to usb-serial generic driver.Joris van Rantwijk2007-02-162-18/+90
| | | | | | | | | | | | | | | | | | I added two fields to struct usb_serial_port to keep track of the throttle state. Other usb-serial drivers typically use private data for such things, but the generic driver can not really do that because some of its code is also used by other drivers (which may have their own private data needs). As it is, I am not sure that this patch is useful in all scenarios. It is certainly helpful for low-bandwidth devices that can hold their data in response to throttling. But for devices that pump data in real-time as fast as possible (webcam, A/D converter, etc), throttling may actually cause more data loss.

* USB: Driver to charge USB blackberry devicesGreg Kroah-Hartman2007-02-164-0/+153
| | | | | | | | | | | | | A simple driver to turn on the charging capability of a USB BlackBerry device when it is plugged into the machine. It does not bind to the device, so all userspace programs can still sync properly with it. Note, if CONFIG_USB_SUSPEND is enabled, it can play havoc with this device as the power to the port will be shut down. This device id will have to be added to the global blacklist table when it is created. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows drm to populate an agpgart structure with pages of its own. It's needed for the new drm memory manager which dynamically flips pages in and out of AGP. The patch modifies the generic functions as well as the intel agp driver. The intel drm driver is currently the only one supporting the new memory manager. Other agp drivers may need some minor fixing up once they have a corresponding memory manager enabled drm driver. AGP memory types >= AGP_USER_TYPES are not populated by the agpgart driver, but the drm is expected to do that, as well as taking care of cache- and tlb flushing when needed. It's not possible to request these types from user space using agpgart ioctls. The Intel driver also gets a new memory type for pages that can be bound cached to the intel GTT.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Start using v2 version of Longhaul when available. It provides voltage scaling and can use ACPI C3 state. That's curious. CPU will not change frequency on ACPI C3 when v1 is in use, but it will when v2 is used. Driver will return max frequency all the time if this isn't true for all processors. There is strange thing with mobile voltage. Looks like only Nehemiah (C3-M) supports it. Earlier processors have different mobile VRM (in docs), but I can't find any which is using it. Looks like all are using VRM 8.5. So fail for non Nehemiah with mobile VRM.

Beta tested by Jorgen (jorgen (at) greven dot dk). Thanks! Based on documentation provided by Dave Jones (Thanks!) and C7 Eden datasheet available from www.via.com.tw. Looks like all these C7 Eden CPU's don't have P-states in BIOS. I know that 2 p-states is low, but Jorgen finds it usefull anyway because board is passive cooled. There are 3 different types of C7 processors (called brands): 0. C7-M - these processors can set any maultiplier between min and max, any voltage between min and max. 1. C7 - only min and max states are supported. Voltage is different for min and max states. 2. Eden - only min and max states are supported. Looks like this brand can only change multiplier.

| * | | | [CPUFREQ] Longhaul - Remove "ignore_latency" optionRafał Bilski2007-02-031-5/+1
| | |/ / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is no need to have this option in Longhaul anymore. It was for laptop with CLE266 chipset in times, when only ACPI C3 was used to switch frequency. Now we have native support not only for CLE266, but CN400 too. Would be good to have support for PN266, but I can't find datasheet for it. Looks like BIOS for CPU's faster then 1GHz don't support ACPI C2 nor C3.

* | | | [PATCH] eCryptfs: Reduce stack usage in ecryptfs_generate_key_packet_set()Michael Halcrow2007-02-163-8/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | eCryptfs is gobbling a lot of stack in ecryptfs_generate_key_packet_set() because it allocates a temporary memory-hungry ecryptfs_key_record struct. This patch introduces a new kmem_cache for that struct and converts ecryptfs_generate_key_packet_set() to use it.

* | | | [PATCH] knfsd: stop NFSD writes from being broken into lots of little writes ↵NeilBrown2007-02-161-13/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | to filesystem When NFSD receives a write request, the data is typically in a number of 1448 byte segments and writev is used to collect them together. Unfortunately, generic_file_buffered_write passes these to the filesystem one at a time, so an e.g. 32K over-write becomes a series of partial-page writes to each page, causing the filesystem to have to pre-read those pages - wasted effort. generic_file_buffered_write handles one segment of the vector at a time as it has to pre-fault in each segment to avoid deadlocks. When writing from kernel-space (and nfsd does) this is not an issue, so generic_file_buffered_write does not need to break and iovec from nfsd into little pieces. This patch avoids the splitting when get_fs is KERNEL_DS as it is from NFSd.
