2011-11-18usb: Netlogic: Use CPU_XLR in place of NLM_XLRJayachandran C
Use CONFIG_CPU_XLR instead of CONFIG_NLM_XLR, the NLM_XLR config option is redundant and is being removed. Signed-off-by: Jayachandran C <jayachandranc@netlogicmicro.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-11-18USB: make the usbfs memory limit configurableAlan Stern
The 16-MB global limit on memory used by usbfs isn't suitable for all people. It's a reasonable default, but there are applications (especially for SuperSpeed devices) that need a lot more. This patch (as1498) creates a writable module parameter for usbcore to control the global limit. The default is still 16 MB, but users can change it at runtime, even after usbcore has been loaded. As a special case, setting the value to 0 is treated the same as the hard limit of 2047 MB. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-11-18USB: change the memory limits in usbfs URB submissionAlan Stern
For a long time people have complained about the limitations imposed by usbfs. URBs coming from userspace are not allowed to have transfer buffers larger than a more-or-less arbitrary maximum. While it is generally a good idea to avoid large transfer buffers (because the data has to be bounced to/from a contiguous kernel-space buffer), it's not the kernel's job to enforce such limits. Programs should be allowed to submit URBs as large as they like; if there isn't sufficient contiguous memory available then the submission will fail with a simple ENOMEM error. On the other hand, we would like to prevent programs from submitting a lot of small URBs and using up all the DMA-able kernel memory. To that end, this patch (as1497) replaces the old limits on individual transfer buffers with a single global limit on the total amount of memory in use by usbfs. The global limit is set to 16 MB as a nice compromise value: not too big, but large enough to hold about 300 ms of data for high-speed transfers.

2011-11-18USB: unify some error pathways in usbfsAlan Stern
This patch (as1496) unifies the error-return pathways of several functions in the usbfs driver. This is not a very important change by itself; it merely prepares the way for the next patch in this series.

2011-11-18USB: remove homegrown UTF conversion routine for gadgetsAlan Stern
This patch (as1502) removes the UTF8-to-UTF16 conversion routine in the USB gadget library and replaces it with a call to the equivalent function in the NLS library. The only downside worth noting is that the NLS library routine requires the output buffer to be 16-bit aligned. This is always true in the gadget code, because the output buffer is always a usb_request buffer being used to send a string descriptor.

2011-11-18OHCI: remove uses of hcd->stateAlan Stern
This patch (as1500) removes all uses of the objectionable hcd->state variable from the ohci-hcd family of drivers. It is replaced by a private ohci->rh_state field, just as in uhci-hcd and ehci-hcd.

2011-11-18USB: convert drivers/usb/* to use module_usb_driver()Greg Kroah-Hartman
This converts the drivers in drivers/usb/* to use the module_usb_driver() macro which makes the code smaller and a bit simpler. Added bonus is that it removes some unneeded kernel log messages about drivers loading and/or unloading.

2011-11-15USB: serial: do not forward USB specific errors in writeJohan Hovold
Use usb_translate_errors() to map USB-specific errors to errors appropriate for user space (ENOMEM, ENODEV and EIO) in write. Currently almost all serial drivers simply forward error codes from the stack (e.g. from usb_submit_urb()), but these codes often have different meanings in user-space. Doing the mapping in usb-serial core simplifies driver code and allows for more consistent error reporting.
