      [IA64] fix interrupt masking for pending works on kernel leave · 3633c730
      Hidetoshi Seto authored
      [Bug-fix for "[BUG?][2.6.25-mm1] sleeping during IRQ disabled"]
      
      This patch does:
       - enable interrupts before calling schedule() as same as others, ex. x86
       - enable interrupts during ia64_do_signal() and ia64_sync_krbs()
       - do_notify_resume_user() is still called with interrupts disabled, since
         we can take short path of fsys_mode if-statement quickly.
       - pfm_handle_work() is also called with interrupts disabled, since
         it can deal interrupt mask within itself.
       - fix/add some comments/notes

      [IA64] allow user to force_pal_cache_flush · f13ae30e
      Alex Chiang authored
      The sequence executed in check_sal_cache_flush:
      
      	- pend a timer interrupt
      	- call SAL_CACHE_FLUSH
      	- see if interrupt is still pending
      
      can hang HP machines with buggy SAL_CACHE_FLUSH implementations.
      
      Provide a kernel command-line argument to allow users skip this
      check if desired. Using this parameter will force ia64_sal_cache_flush
      to call ia64_pal_cache_flush() instead of SAL_CACHE_FLUSH.

      [IA64] Don't reserve crashkernel memory > 4 GB · 8a3360f0
      Bernhard Walle authored
      Some IA64 machines map all cell-local memory above 4 GB (32 bit limit).
      However, in most cases, the kernel needs some memory below that limit that is
      DMA-capable. So in this machine configuration, the crashkernel will be reserved
      above 4 GB.
      
      For machines that use SWIOTLB implementation because they lack an I/O MMU
      the low memory is required by the SWIOTLB implementation. In that case,
      it doesn't make sense to reserve the crashkernel at all because it's unusable
      for kdump.
      
      A special case is the "hpzx1" machine vector. In theory, it has a I/O MMU, so
      it can be booted above 4 GB. However, in the kdump case that is not possible
      because of changeset 51b58e3e:
      
          On HP zx1 machines, the 'machvec=dig' parameter is needed for the kdump
          kernel to avoid problems with the HP sba iommu.  The problem is that during
          the boot of the kdump kernel, the iommu is re-initialized, so in-flight DMA
          from improperly shutdown drivers causes an IOTLB miss which leads to an
          MCA.  With kdump, the idea is to get into the kdump kernel with as little
          code as we can, so shutting down drivers properly is not an option.
      
          The workaround is to add 'machvec=dig' to the kdump kernel boot parameters.
          This makes the kdump kernel avoid using the sba iommu altogether, leaving
          the IOTLB intact.  Any ongoing DMA falls harmlessly outside the kdump
          kernel.  After the kdump kernel reboots, all devices will have been
          shutdown properly and DMA stopped.
      
      This patch pushes that functionality into the sba iommu initialization
      code, so that users won't have to find the obscure documentation telling
      them about 'machvec=dig'.
      
      This means that also for hpzx1 it's not possible to boot when all
      memory is above the 4 GB limit. So the only machine vectors that can handle
      this case are "sn2" and "uv".

      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: 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).

      USB: serial gadget: simplify endpoint handling · 734d37c6
      David Brownell authored
      Switch serial gadget away from a *very* old idiom:  just remember
      the endpoints we'll be using, instead of looking them up by name
      each time.  This is a net code and data (globals) shrink.
      
      Also fix a small memory leak in the rmmod path, by working the
      same as the disconnect code.

      USB: serial gadget: remove needless data structure · 2c2d28a0
      David Brownell authored
      This removes a needless data structure from the serial gadget code;
      it's a small code shrink, and a larger data shrink.
      
      Since "struct usb_request" already has a "struct list_head" reserved
      for use by gadget drivers, the serial gadget code doesn't need to
      allocate wrapper structs to hold that list ... it can (and should!)
      just use the list_head provided for that exact use.

      USB: serial gadget: cleanup/reorg · 9079e91b
      David Brownell authored
      Some cleanup/reorg of g_serial ... simplifying it, and disentangling
      its structure so morphing it into a "function" driver (combinable with
      other interfaces) should be less painful.
      
       - Remove most forward declarations
           * put tty and gadget driver structs after their contents
           * snug module init/exit decls next to their functions
           * reordered some functions
      
       - Other cleanup:
           * convert a funky macro to an inline function
           * snug up module params next to their declarations
           * add missing driver.owner
           * add separator lines between major driver sections
      
       - Add comments re potential parameter/#define changes:
           * only supports one port (shrank GS_NUM_PORTS)
           * changing from 9600-8-N-1 affects multiple sites
      
       - Remove net2280-specific optimization ... it was being done
         way too late, can be done by net2280 module options, and in
         any case doesn't matter at any sane serial data rates.
      
      There are no behavioral changes, but the macro thing saves I-space.

      USB: do not handle device 1410:5010 in 'option' driver · cdafc37a
      Eugeniy Meshcheryakov authored
      This device is not a serial port, but a virtual CD-ROM device. For
      example with my Novatel MC950D:
      
      lsusb -v -d 1410:5010 | grep InterfaceClass
            bInterfaceClass         8 Mass Storage
      
      After some time (ca. 5min) or if virtual CD is ejected, device id
      changes to 1410:4400:
      
      % lsusb -v -d 1410:4400 | grep InterfaceClass
            bInterfaceClass       255 Vendor Specific Class
            bInterfaceClass       255 Vendor Specific Class
      
      Variable name says that 0x5010 is a Novatel U727, but searching in
      internet shows, that this device also provides virtual CD that should be
      ejected before use. Product id for serial port in this case is 0x4100.

      USB: add Zoom Telephonics Model 3095F V.92 USB Mini External modem to cdc-acm · 6149ed5e
      Iain McFarlane authored
      The patch below is a necessary workaround to support the Zoom Telephonics Model 3095F V.92 USB Mini External modem, which fails to initialise properly during normal probing thus:
      
      May  3 22:53:00 imcfarla kernel: drivers/usb/class/cdc-acm.c: Zero length descriptor references
      May  3 22:53:00 imcfarla kernel: cdc_acm: probe of 5-2:1.0 failed with error -22
      
      Adding the patch below causes the probing section to be skipped, and the modem
      then initialises correctly.

      USB: create attributes before sending uevent · 2e5f10e4
      Alan Stern authored
      This patch (as1087d) fixes a long-standing problem in usbcore: Device,
      interface, and endpoint attributes aren't added until _after_ the
      creation uevent has already been broadcast.
      
      Unfortunately there are a few attributes which cannot be created that
      early.  The "descriptors" attribute is binary and so must be created
      separately.  The power-management attributes can't be created until
      the dev/power/ group exists.  And the interface string can vary from
      one altsetting to another, so it has to be created dynamically.
