Summary of changes from v2.5.55 to v2.5.56
============================================

<rmk@flint.arm.linux.org.uk>
   [SERIAL] Add prototypes and rename UPF_FLAGS
   
   UPF_FLAGS is confusing - rename it to UPF_CHANGE_MASK.
   Add uart_update_timeout, uart_get_baud_rate and uart_get_divisor
   prototypes.

<rmk@flint.arm.linux.org.uk>
   [SERIAL] Remove unused info->event

<rmk@flint.arm.linux.org.uk>
   [SERIAL] Convert change_speed() to settermios()
   
   Several serial drivers want to obtain the numeric baud rate when
   configuring their serial ports.  Currently, two methods are used
   to "work around" this inadequacy in the change_speed API:
   
      baud = tty_get_baud_rate(port->info->tty);
   
      baud = BAUD_BASE / (16 * quot);
   
   Passing the termios structure down means that we can use 
   uart_get_baud_rate() instead.  We can also ensure that the various
   termios flags for options we don't support are correctly set.
   
   Lastly, this also provides 8250.c with a clean method for supporting
   divisors that are greater than the baud_base.

   ACPI: Use printk instead of pr_debug (Randy Dunlap)

<rmk@flint.arm.linux.org.uk>
   [SERIAL] Change settermios to set_termios
   
   set_termios matches the style used for the other methods.  It should
   have been this from the start.

<david-b@pacbell.net>
   [PATCH] ehci, remove potential hangs
   
   These don't affect the hang I'm hunting for, but paranoia
   argues the patch is better integrated than not:
   
   - prevent resubmit-from-completion looping in_irq if the
      transfers complete really fast.  (likely never seen, but...)
   
   - grab ehci lock before reading irq status; should be harmless
      except in one host error cleanup-after-death

<david-b@pacbell.net>
   [PATCH] zaurus B500 (sl-5600?) & usbnet
   
   More Zaurii.  That model will be interesting from the
   perspective of "usb gadget drivers", lots of flexible
   endpoints are available.

<petkan@users.sourceforge.net>
   [PATCH] USB pegasus: small patch for 2.5
   
   Same as the previous email, just against latest linux-2.5 tree.  Sorry
   about the diffs - i can't sync with usb-2.5.

<petkan@users.sourceforge.net>
   [PATCH] again rtl8150
   
   this diff is agains the latest linux-2.5;
   set mac address at dev->open()
   (as per Jeff Garzik :-)

<oliver@neukum.name>
   [PATCH] USB: kaweth freeing skbs
   
   this is the 2.5 version of the 2.4 fix
     - proper freeing of skbs

<david-b@pacbell.net>
   [PATCH] 2.5.54 -- ohci-dbg.c: 358: In function `show_list': `data1'
   
   OK here's the version that without the kernel version #ifdef
   that helped the backport ... it fixes the build by restoring
   the "debug support only if CONFIG_USB_DEBUG" semantics.

<david-b@pacbell.net>
   [PATCH] usbtest, covers control queueing and fault cleanup
   
   I wrote this a while back, finally debugged it.  This covers
   some functionality that 2.5 newly demands of all HCDs:  control
   requests can be queued.  (Example:  a user mode driver can talk
   on one interface, and a kernel mode one can talk on another,
   no need to handshake about who can make control requests.)
   
   The good news is that all the HCDs seem (light testing) to do
   the right things ... until some of the requests (intentionally)
   trigger routine faults (like protocol stalls) which the HCDs
   need to recover from.  At that point, uhci-hcd started acting
   confused (it's got newish queueing code); details will come
   separately.  The other two HCDs acted fine.  I had expected more
   trouble there, maybe it'll show up later on.

<greg@kroah.com>
   USB: revert davem's compile time fix, now that it's fixed properly.

<mdharm-usb@one-eyed-alien.net>
   [PATCH] USB storage: remove usb_stor_tranfer_length()
   
   This patch removes the (often troublesome) usb_stor_transfer_length()
   function.
   
   We've finally gotten all the command initiators to send the correct values
   in the srb->request_bufflen field, so this is no longer needed.
   
   There are probably some sanity checks that can also be removed now, but
   that's for a later patch.

   Thanks to Dave Jones for pointing this out.

<greg@kroah.com>
   [PATCH] DEV: change dev_printk() to take a pointer to dev instead of the structure itself.
   
   This was suggested by many people, Randy Dunlap being the most vocal :)

<greg@kroah.com>
   [PATCH] USB: drivers/usb/core/ fixups due to dev_printk change

   [PATCH] USB: drivers/usb/serial/ fixups due to dev_printk change

<henning@meier-geinitz.de>
   [PATCH] scanner.c: fix race in ioctl_scanner()
   
   This patch adds locking to ioctl_scanner() which was completely
   lacking until now. The patch is originally from Oliver Neukum
   <oliver@neukum.name>.
   
   The patch was forward-ported from 2.4.

<henning@meier-geinitz.de>
   [PATCH] USB scanner driver: updated documentation
   
   This patch updates the documentation for the USB scanner driver. The
   details:
   
   Documentation/usb/scanner.txt:
     - Amended for linux-2.5.54
     - Added information about read_timeout
     - Added more details about /proc/bus/usb/devices
     - Added/updated links
     - Added pointers two "special" scanner drivers
     - Reordering, spell-checking, formatting
     - Used /dev/usb/scanner[0-15] instead of /dev/usbscanner[0-15]
     - Removed some basic USB configuration stuff
     - Added EHCI
     - Removed some more references to HP
   
   Documentation/usb/scanner-hp-sane.txt:
     Removed completely. This was a very outdated text for some HP
     scanners. All of this is explained in the documentation of the
     user-space SANE tools. Links and a short explanation about SANE was
     added to scanner.txt instead.
   
   This is the (slightly adapted) patch you already apllied for 2.4.

<henning@meier-geinitz.de>
   [PATCH] USB scanner driver: updated Kconfig
   
   This patch removes the link in Kconfig to
   Documentation/usb/scanner-hp-sane.txt which was removed by the
   documentation update.

<henning@meier-geinitz.de>
   [PATCH] scanner.c, scanner.h: Added vendor/product ids
   
   This patch adds vendor/product ids for two Visioneer scanners.
   
   The patch is on top of the ioctl patch.

<henning@meier-geinitz.de>
   [PATCH] scanner.c: print user-supplied ids only on start-up
   
   With this patch, information about user-supplied ids is printed only
   once at startup instead of everytime any USB device is plugged in.
   
   The patch is on top of the new ids patch.

<agrover@groveronline.com>
   ACPI: Remove typedefs in favor of using "struct" and "union" explicitly

<pablo@menichini.com.ar>
   [PATCH] 2.5.54 dev_*(&<dev>,...): drivers/usb/input/pid.c

<henning@meier-geinitz.de>
   [PATCH] scanner.c, scanner.h: Remove PV8630 ioctls
   
   This patch removes the inofficial ioctls that were used to support the
   PV8630 USB-over-Parport chipset. They were alreaded ifdefed out.
   Instead of them, the more generic (and official) SCANNER_IOCTL_CTRLMSG
   should be used. The last software that used the old ioctl
   (sane-hp4200) switched to the new ioctls a long time ago.
   
   This patch is ontop of the "user-supplied" patch.

<greg@kroah.com>
   [PATCH] USB serial: pass the usb_device_id to the probe() function
   
   This is needed for drivers that want to use the driver_info field.

<greg@kroah.com>
   [PATCH] USB serial: fixup for probe function paramaters changing.

   endpoint is required, everything else is optional.
   
   The patch is on top of the PV8630 removal patch.

<baldrick@wanadoo.fr>
   [PATCH] USB: atmsar is not a module
   
   atmsar is not a module in its own right, it is an auxiliary library for speedtouch.
   So remove module code from atmsar and build module speedtch from speedtouch and
   atmsar.  Note the module name change speedtouch -> speedtch (speedtch is the name
    used for the original 2.4 module, and is the name used in the online documentation).

   Here is the same for 2.5.44:

<neilt@slimy.greenend.org.uk>
   [PATCH] USB Serial patch for old pl2303 devices.
   
   I got a PL2303 USB serial converter a few days ago, and got your driver
   up and running fairly quickly.  The problem is that I got an oops when I
   rmmod-ed the drivers.  The pl2303 uses two interfaces but registers only
   the second (technically wrong, I guess, but should work).  When pl2303.o
   is removed, it attempts to deregister the first interface (which has no
   effect), so the second interface remains registered with usbserial.  The
   old struct serial still points at the removed pl2303 driver so things go
   pop when anything touches it.
   
   I think the PL2303 hack in usb_serial_probe should not change the
   "interface" variable, which gets stored in serial->interface, since
   usbcore will register whatever "ifnum" says.  I think that's enough
   waffle.  The patch is below.  Keep up the good work!

   PPC32: Handle machine checks on 4xx processors better.
   
   This also cleans up the machine check code generally.

   [SERIAL] Bug fix: remove infinite loop in sa1100 serial driver.

<rmk@flint.arm.linux.org.uk>
   [SERIAL] Restrict the baud rates returnable from uart_get_baud_rate()
   
   Supply the old termios, along with the max and min acceptable baud
   rate to uart_get_baud_rate().  uart_get_baud_rate() will now try to
   find a baud rate that satisfies the max and min constraint out of
   (requested rate, old rate, 9600 baud).
   
   We remove the code which performed a similar act in uart_get_divisor()
   and pass an appropriate min and max baud rate to uart_get_baud_rate()
   based on the UART clock rate.

<greg@kroah.com>
   USB: fix ehci build for older versions of gcc

<ldb@ldb.ods.org>
   [PATCH] Use %ebp rather than %ebx for thread_info pointer
   
   This patch changes assembly code that accesses thread_info to use %ebp
   rather than %ebx.
   
   This allows me to take advantage of the fact that %ebp is restored by
   user mode in the sysenter register pop removal patch.
   
   vm86() direct return code updated to match [ Linus ]

<ldb@ldb.ods.org>
   [PATCH] Remove all register pops before sysexit
   
   This patch, which depends on the previous %ebx -> %ebp patch, removes
   all pop instruction in the sysenter return path.
   
   This leaks the thread_info address to user mode but this shouldn't be
   a security problem.
   
   This is what happens to the various registers:
   
      %eax: return value from system call: already in place
      %ebx, %esi, %edi: saved by the C compiler
      %ecx, %edx, %ebp: restored by user mode, fixed values by kernels
      %esp, eip: copied to %ecx/%edx and restored by sysexit
      %ds, %es: initialized to __USER_DS on kernel entry
      %cs, %ss: restored by sysexit based on msr
      %fs, %gs: not modified by the kernel (saved around context switch)
      eflags: not preserved, iopl saved around context switch
      FP, XMM: any code that modifies them must save/restore them
   
   Note that while it is possible to change %ebx, %esi, %edi, %ecx, %edx
   or %ebp via struct pt_regs, anything that does should set TIF_IRET or
   another work flag (and it hopefully already does).
