2007-04-25[SK_BUFF]: Convert skb->end to sk_buff_data_tArnaldo Carvalho de Melo

2007-04-25[SK_BUFF]: Convert skb->tail to sk_buff_data_tArnaldo Carvalho de Melo
So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes on 64bit architectures, allowing us to combine the 4 bytes hole left by the layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4 64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN... :-) Many calculations that previously required that skb->{transport,network, mac}_header be first converted to a pointer now can be done directly, being meaningful as offsets or pointers.

2007-04-24usb-net/pegasus: fix pegasus carrier detectionDan Williams
Broken by 4a1728a28a193aa388900714bbb1f375e08a6d8e which switched the return semantics of read_mii_word() but didn't fix usage of read_mii_word() to conform to the new semantics. Setting carrier to off based on the NO_CARRIER flag is also incorrect as that flag only triggers on TX failure and therefore isn't correct when no frames are being transmitted. Since there is already a 2*HZ MII carrier check going on, defer to that. Add a TRUST_LINK_STATUS feature flag for adapters where the LINK_STATUS flag is actually correct, and use that rather than the NO_CARRIER flag.

2007-04-11EHCI: fix remote wakeup regression in 2.6.21-rcAlan Stern
There is one significant difference between the behavior of root hubs (as embodied in host controller hardware) and external hubs: When a remote-wakeup signal is received, an external hub sends an interrupt message at the _end_ of the resume sequence but a root hub generates and interrupt at the _beginning_ of the resume sequence. The host system must poll for the end of the sequence. When ehci-hcd was converted to interrupt-driven operation instead of using polling, the remaining need for this particular poll was overlooked. This patch (as894) fixes the problem. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2007-03-26USB: remove duplicated device id in airprime driverJon K Hellan
Both airprime and option now want to handle vendor ID 0x1410, device ID 0x1100. Airprime calls it 'ExpressCard34 Qualcomm 3G CDMA'. Option calls it 'Novatel Merlin XS620/S640'.

2007-03-26USB: omap_udc: workaround dma_free_coherent() bogosityDavid Brownell
Various fixes to omap_udc, noted with some recent testing: - Cope with some SMP-induced braindamage in ARM's dma_{alloc,free}_coherent() implementation: alloc() can be called with IRQs blocked, but since late last year that's no longer true for free(). This resolves really NASTY problems with logspamming via WARN_ON(), indicating N-page leaks. - Be more correct in handling GET_STATUS request for RECIP_ENDPOINT ... the previous code only handled RECIP_INTERFACE, this version should be correct except for (sigh) bulk/interrupt endpoints. - Provide a better name for the function reporting whether the board has vbus sensing wired up. GET_STATUS requests for endpoint status still acts strangely though, at least given one flakey host doesn't always ack the first DATA packet, then the packet that gets retransmitted doesn't have data!

2007-03-26UHCI: Fix problem caused by lack of terminating QHAlan Stern
This patch (as871) fixes a problem introduced by an earlier change. It turns out that some systems really do need to have a terminating skeleton QH present whenever FSBR is on. I don't know any way to tell which systems do need it and which don't; the easiest answer is to have it there always. This fixes the NumLock-hang bug reported by Jiri Slaby.

Add an ID to recognise the Novatel EV620 wireless adapter. http://www.novatelwireless.com/products/expedite/ev620.html It looks like a mini PCI-Express adapter. The mPCIE connector includes USB pins... the card shows up to the system as a USB device, and powers itself from the PCI bus. The card I have isn't activated yet, so I can't get a PPP session up yet, but I have tested basic serial communication successfully in both 2.6.18 and 2.6.20 kernels, once the product ID was added. (the driver changed quite a bit between the two revs.) In both drivers, it responds to AT commands and such.

these devices have a shared interrupt endpoint. For serialcore to pass an interrupt endpoint to a subdriver, the subdriver must define and _export_ a fitting callback.

Here is a patch adding the PID for the FT232RL to ftdi_sio.

2007-03-09USB: RTS/DTR signal patch for airprime driverMartin Schiller
I encountered some problems with the airprime driver in use with a Novatel Merlin XU870: Closing an open Connection to e.g. /dev/ttyUSB0 doesn't reset the RTS/DTR lines of the Modem. Consequently, when I use minicom to establish a connection by "ATD*99#" the modem doesn't hang up even if i exit minicom and so I cannot reuse the modem unless I remove it and plug it in again. With the attached patch, the RTS/DTR lines are resetted on a close. The code was mainly taken from the option.c driver.

2007-03-01HID: fix Logitech DiNovo Edge touchwheel and Logic3 /SpectraVideo middle buttonJiri Kosina
Dongle shipped with Logitech DiNovo Edge (0x046d/0xc714) behaves in a weird non-standard way - it contains multiple reports with the same usage, which results in remapping of GenericDesktop.X and GenericDesktop.Y usages to GenericDesktop.Z and GenericDesktop.RX respectively, thus rendering the touchwheel unusable. The commit 35068976916fdef82d6e69ef1f8c9a1c47732759 solved this in a way that it didn't remap certain usages. This however breaks (at least) middle button of Logic3 / SpectraVideo (0x1267/0x0210), which in contrary requires the remapping. To make both of the harware work, allow remapping of these usages again, and introduce a quirk for Logitech DiNovo Edge "touchwheel" instead - we disable remapping for key, abs and rel events only for this hardware.
