2009-09-23headers: utsname.h reduxAlexey Dobriyan
* remove asm/atomic.h inclusion from linux/utsname.h -- not needed after kref conversion * remove linux/utsname.h inclusion from files which do not need it NOTE: it looks like fs/binfmt_elf.c do not need utsname.h, however due to some personality stuff it _is_ needed -- cowardly leave ELF-related headers and files alone.

2009-09-23USB: gadget: Add EEM gadget driverBrian Niebuhr
This patch adds a CDC EEM ethernet gadget driver. CDC EEM is a newer USB ethernet specification that uses a simpler interface than the older CDC ECM. This makes CDC EEM usable by a wider set of USB hardware. By default the ethernet gadget will still use CDC ECM/Subset, but kernel configuration and/or a module parameter will allow alternative use of the CDC EEM protocol. Changes since last version: - Brought in missing RNDIS changes that caused compile error - Modified 'sentinel CRC' checking to match EEM host driver Signed-off-by: Brian Niebuhr <bniebuhr@efjohnson.com> Cc: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2009-09-23USB: gadget: audio driver seg-fault fixRobin Callender
The included patch can be applied to the new usb gadget audio driver. It addresses a seg-fault in uncovered in g_audio.ko. The fault occurs in the function u_audio.c::gaudio_open_end_dev() when device /dev/snd/pcmC0D0c (FILE_PCM_CAPTURE) is not present. I suspect there may be similar problems with device /dev/snd/pcmC0D0p (FILE_PCM_PLAYBACK) handling also. I leave that for the developer(s), as I was unsure as to the side-effects of not calling playback_default_hw_params() in the initialization phase.

2009-09-23USB: dummy-hcd: accept mismatch between wLength and transfer lengthAlan Stern
This patch (as1269) fixes a bug in the way dummy_hcd handles control URBs. Currently it returns a -EOVERFLOW error if the wLength value in the setup packet is different from the URB's transfer_buffer_length. Other host controller drivers don't do this. There's no reason the two length values have to be equal, and in fact they sometimes aren't -- a driver might set the transfer length to the maxpacket value in order to handle buggy devices that don't respect wLength. This patch simply removes the unnecessary check and error return. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2009-08-12f_phonet: use page-sized rather than MTU-sized RX buffersRémi Denis-Courmont
Instead of a large (physically) linear buffer, we generate a set of paged sk_buff, so no extra memory copy is involved. This removes high-order allocations and saves quite a bit of memory. Phonet MTU is 65541 bytes, so the two buffers were padded to 128 kilo-bytes each. Now, we create 17 page buffers, almost a 75% memory use reduction.

2009-07-23usb: m66592-udc platform data on_chip supportMagnus Damm
Convert the m66592-udc driver to use the on_chip flag from platform data to enable on chip behaviour instead of relying on CONFIG_SUPERH_BUILT_IN_M66592 ugliness. This makes the code cleaner and also allows us to support both external and internal m66592 with the same kernel. It also makes the Kconfig part more future proof since we with this patch can add support for new processors with on-chip m66592 without modifying the Kconfig. The patch adds a m66592 header file for platform data and ties in platform data to the existing m66592 devices.
