      Some devices, like md, may create partitions only at first access,
      so allow root= to be set to a valid non-existant partition of an
      existing disk. This applies only to non-initramfs root mounting.
      
      This fixes a regression from 2.6.24 which did allow this to happen and
      broke some users machines :(

      fix SMP data race in pagetable setup vs walking · 362a61ad
      Nick Piggin authored
      
      
      There is a possible data race in the page table walking code. After the split
      ptlock patches, it actually seems to have been introduced to the core code, but
      even before that I think it would have impacted some architectures (powerpc
      and sparc64, at least, walk the page tables without taking locks eg. see
      find_linux_pte()).
      
      The race is as follows:
      The pte page is allocated, zeroed, and its struct page gets its spinlock
      initialized. The mm-wide ptl is then taken, and then the pte page is inserted
      into the pagetables.
      
      At this point, the spinlock is not guaranteed to have ordered the previous
      stores to initialize the pte page with the subsequent store to put it in the
      page tables. So another Linux page table walker might be walking down (without
      any locks, because we have split-leaf-ptls), and find that new pte we've
      inserted. It might try to take the spinlock before the store from the other
      CPU initializes it. And subsequently it might read a pte_t out before stores
      from the other CPU have cleared the memory.
      
      There are also similar races in higher levels of the page tables. They
      obviously don't involve the spinlock, but could see uninitialized memory.
      
      Arch code and hardware pagetable walkers that walk the pagetables without
      locks could see similar uninitialized memory problems, regardless of whether
      split ptes are enabled or not.
      
      I prefer to put the barriers in core code, because that's where the higher
      level logic happens, but the page table accessors are per-arch, and open-coding
      them everywhere I don't think is an option. I'll put the read-side barriers
      in alpha arch code for now (other architectures perform data-dependent loads
      in order).

      USB: atmel_usba_udc fixes, mostly disconnect() · 40517707
      David Brownell authored
      
      
      Various fixes to Atmel's high speed UDC driver.
      
        * Issue some missing disconnect() calls.  Currently they are only made
          when VBUS power goes away (on boards where the driver can sense such
          changes), but that's not enough for gadget drivers to clean out all
          the state that's needed.  Missing calls were:
      
            - After USB reset, before starting enumeration.
            - When unregistering a gadget driver, before unbind().
      
        * Don't assume gadget drivers provide disconnect callbacks; make sure
          to not call through a null pointer!
      
        * When the driver doesn't provide an unbind() callback, refuse to
          unregister it.
      
      Also remove two bogus "error" messages:
      
        * Related to mis-handling of disconnect() ... don't emit error messages
          for disconnect() handlers that disable endpoints.  All of them should
          be doing that; the problem is (unfixed) oddness in atmel_usba_udc.
      
        * Don't emit a diagnostic for a curious and transient nonfatal error
          that shows up sometimes with EP0.
      
      Those messages spammed syslog, for no good reason.

      USB: remove PICDEM FS USB demo (04d8:000c) device from ldusb · 5fc89390
      Xiaofan Chen authored
      Microchip has changed the PICDEM FS USB demo device (0x04d8:000c)
      to use bulk transfer and not interrupt transfer. So I've updated the libusb
      based program here (Post #31).
      	http://forum.microchip.com/tm.aspx?m=106426&mpage=2
      
      
      
      So I believe that the in-kernel ldusb driver will no longer work with the
      demo firmware.  It should be removed.

      Enables the SD-Card interface on the GI 0401 HSUPA card from Option.
      
      The unusual_devs.h entry is necessary because the device descriptor is
      vendor-specific. That prevents usb-storage from binding to it as an
      interface driver.
      
      This revised patch adds a small comment explaining why and reduces the
      rev range.

      USB: serial gadget: descriptor cleanup · b9370332
      David Brownell authored
      
      
      Bugfix some serial gadget descriptors:
      
       - Stop mangling the low bits (controller type ID) of bcdDevice;
         just use the high bits for a driver revision code.
      
       - Serial numbers that aren't specific to individual devices
         are useless; stop reporting "0" for this.
      
       - Since it's not part of a CDC-conformant function, the "bulk only"
         configuration shouldn't be using "CDC Data" as its interface class.
         Switch over to using CLASS_VENDOR_SPEC (different value, 0xff).
