      USB serial drivers · c3cdeb68
      Ganesh Varadarajan authored
      Several functions in the serial drivers can be called from bottom
      half or interrupt context. They must use the GFP_ATOMIC flag for
      calls to kmalloc() and usb_submit_urb().
        
      Functions which must use GFP_ATOMIC:
      1. All *_callback() functions.
      2. Any code which is inside a spinlock.
      3. write(), throttle(), unthrottle(), which may be called by
         the line discipline in bottom half context.
        
      Functions which can use GFP_KERNEL:
      1. open(), close(), startup(), shutdown(), set_termios().

      USB catc driver · 869de8b7
      Simon Evans authored
        
      Here is a patch to add support for F5U011 to catc.c driver. The
      patch has been compile tested against 2.5.6 and 2.5.7pre1
      (and tested against 2.5.5-dj1) and should apply cleanly.

      USB Urefs for hid-core/hiddev · 36a9bab9
      Paul Stewart authored
        I've written a patch Vojtech and I discussed for enhancing the
      hiddev code to optionally provide more detailed output on read().
      The old functionality is still supported by default, and in
      situations where HID usage codes are unique across reports, the
      old method is still preferable due to its terseness.
          
        The new method provides the ability to determine exactly which
      value has changed, in cases where the HID usage codes are not  
      unique.  It also provides a means to optionally receive notification
      when input reports are received from the device, whether or not
      any of the values in the report have changed.
      
        The details of the changes are as follows:
        
        - All current code behaves identically
      
        - A new ioctl pair HIDIOCGFLAG/HIDIOCSFLAG gets and clears
          flags on the hiddev device.                             
      
        - If you set the flag HIDDEV_FLAG_UREF, the read() call switches
          from reading hiddev_event structures to hiddev_usage_ref
          structures.  The change takes effect immediately, even to
          already queued events that haven't been read() yet.  Here's
          an example of enabling FLAG_UREF:                          
      
          {
              int flag = HIDDEV_FLAG_UREF;
              if (ioctl(fd, HIDIOCSFLAG, &flag) != 0) {
                      perror("ioctl");
                      exit(1);
              }
          }
        
        - With the HIDDEV_FLAG_REPORT set (which is only allowed if
          HIDDEV_FLAG_UREF is also set), there is a special uref that
          will be read() in addition to the ones corresponding to
          changes in the device state: when uref.field_index is set to
          HID_FIELD_INDEX_NONE, this uref is a notification that the
          report referred to by report_type and report_id has been
          received from the device.  This can be useful in situations
          when the notification of the arrival of a report is useful
          even if there is no change in state.

      USB printer update · bb94ccec
      David Paschal authored
      - bind to 7/1/2 alternate setting by default, to fix printing with HP
        LaserJet 1200 and 2200
      - ioctls needed by the GPL user-mode IEEE 1284.4 driver which is part of
        the HP OfficeJet Linux driver (http://hpoj.sourceforge.net):
        - dynamic switching between 7/1/[123] alternate settings
        - sending HP vendor-specific channel-change-request to support
          memory card readers on HP PhotoSmart printers
        - inquire more information about the peripheral, including
          /proc/bus/usb/xx/yy linkage to get even more information
      - fix apparent array overflow (by 1 entry) in usblp_probe when more than
        the maximum number of USB printers are connected
      - for the 2.2 version, added MODULE_{INC,DEC}_USE_COUNT to prevent rmmoding
        of printer.o (and subsequent OOPSes) while a USB printer device is open
      - cleaned up the code in a few places by consolidating duplicated code

      Andy Grover authored
      If you could only review one of the 9 patches, this would be the one.
      
      - removes acpitable.c vestiges
      - adds ACPI IRQ routing support to PCI (disableable via pci=noacpi option)
      - adds code to get a <1MB page for sleep, and ACPI boot to setup.c
      - allocates another page in the fixmap for ACPI
      - changes driverfs a little to work better with ACPI.

      This is the first of 9 patches. We did a complete rewrite of the

      There will be more updates, but *much* smaller.
      
      #1 - this updates the header file.

      [PATCH] boot_cpu_data corruption on SMP x86 · 1ae90c54
      Mikael Pettersson authored
      The patch below eliminates a case of boot_cpu_data corruption
      on SMP x86 machines. This was first observed on SMP Athlons,
      but it also affects SMP Intel boxes in a less serious way.
      
      When the secondary processors boot and execute head.S:checkCPUtype,
      the code performs a 32-bit write of a small constant to the
      byte-sized variable boot_cpu_data.x86 (X86 in head.S). Since the
      write is 32-bit, it also writes zeros to the following 3 bytes,
      which clobbers the x86_vendor, x86_model, and x86_mask fields
      previously set up by check_bugs()'s call to identify_cpu().
      Thus, after smp_init(), boot_cpu_data will _always_ identify
      the CPU as an Intel (X86_VENDOR_INTEL == 0 in processor.h) with
      model 0 and stepping 0.
      
      The effect in standard kernels is not catastrophic, since:
      (a) most SMP x86 boxes are Intel
      (b) most uses of x86_vendor occur before smp_init() or reference
          the SMP cpu_data[] array
      (c) most post-boot references to boot_cpu_data occur in the
          cpu_has_XXX macros which only read the x86_capability[] array
      However, third-party extensions (like my x86 performance-monitoring
      conters driver) can get seriously confused by this mis-identification.
