2014-01-03USB: pl2303: add device-type abstractionJohan Hovold
Encode all device-type specifics in a struct rather than testing for device type and spreading such information throughout the driver. Signed-off-by: Johan Hovold <jhovold@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-01-03USB: pl2303: add quirk for legacy devicesJohan Hovold

2014-01-03USB: pl2303: clean up type handlingJohan Hovold

2014-01-03USB: pl2303: add line-status quirk for Siemens phonesJohan Hovold
Implement line-status handling for Siemens phones as a quirk rather than spreading such information all over the driver by matching on vendor and and product ids. Note that the SIEMENS_PRODUCT_ID_EF81, which was added after the line-status handling for the other Siemens phones was fixed, might also need this quirk.

2014-01-03USB: pl2303: remove bogus delta_msr_wait wake upJohan Hovold
Remove bogus MSR wait-queue wake up from process_read_urb which never updates the MSR flags. Signed-off-by: Johan Hovold <jhovold@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-01-03USB: f81232: switch to generic tiocmiwaitJohan Hovold
Switch to generic tiocmiwait rather than rely on a custom implementation using racy interruptible_sleep_on(). Note that this driver is mostly stubbed out so neither version of tiocmiwait will actually work until someone implements f81232_update_line_status().

2014-01-03USB: f81232: remove bogus call to wake up MSR queueJohan Hovold
Remove bogus call to wake up delta_msr_wait from process_read_urb where the MSR status is never updated (only the LSR bits are masked out). Comment that the wake-up call should made in f81232_update_line_status when the MSR status changes. Note that this driver is still mostly stubbed out.

2014-01-03USB: pl2303: fix data corruption on termios updatesJohan Hovold
Some PL2303 devices are known to lose bytes if you change serial settings even to the same values as before. Avoid this by comparing the encoded settings with the previsouly used ones before configuring the device. The common case was fixed by commit bf5e5834bffc6 ("pl2303: Fix mode switching regression"), but this problem was still possible to trigger, for instance, by using the TCSETS2-interface to repeatedly request 115201 baud, which gets mapped to 115200 and thus always triggers a settings update.

2013-12-22aio: clean up and fix aio_setup_ring page mappingLinus Torvalds
Since commit 36bc08cc01709 ("fs/aio: Add support to aio ring pages migration") the aio ring setup code has used a special per-ring backing inode for the page allocations, rather than just using random anonymous pages. However, rather than remembering the pages as it allocated them, it would allocate the pages, insert them into the file mapping (dirty, so that they couldn't be free'd), and then forget about them. And then to look them up again, it would mmap the mapping, and then use "get_user_pages()" to get back an array of the pages we just created. Now, not only is that incredibly inefficient, it also leaked all the pages if the mmap failed (which could happen due to excessive number of mappings, for example). So clean it all up, making it much more straightforward. Also remove some left-overs of the previous (broken) mm_populate() usage that was removed in commit d6c355c7dabc ("aio: fix race in ring buffer page lookup introduced by page migration support") but left the pointless and now misleading MAP_POPULATE flag around.

2013-12-21USB: core: remove CONFIG_USB_DEBUG usageGreg Kroah-Hartman
CONFIG_USB_DEBUG is going away, so remove the few places in the USB core that relied on them. This means that we always now do the "debug" checks for every urb submitted, which is a good idea, as who knows how many driver bugs we have been ignoring when people forget to enable this option. Also, with the overall speed of USB, doing these extra checks should not cause any additional overhead. Also, no longer announce all devices being added to the system if CONFIG_USB_DEBUG is enabled, as it's not going to be around much longer.
