- added calc_num_ports() ability to determine the number of actual
  ports the device has on the fly.  This should help out with some
  of the Palm and Sony devices.

	- added calc_num_ports() callback so that driver can override the
	  fixed num_ports value after querying the device.
	- split startup() callback into probe() and attach() in anticipation
	  of the driverfs api changes
	- probe() is called before the usb_serial structure is set up,
	  and can be used to download firmware to a device, and other
	  early initialization.
	- attach() is called after the usb_serial structure is completely
	  setup, allowing the device to create private structures, and
	  have full access to the device.

during debugging ALSA's usb audio driver, it's found out that there
are devices with insuccessive alternate settings.

for example, m-audio's quattro usb audio has audio streaming
descriptors jumping from altset 0 to 4 or 3.

apparently, usb_set_interface() sends the array index instead of the
actual altset value.  the attached patch fixes this behavior.

ioctl(LPGETSTATUS) is known to put the status into  an  int.  The  usblp
driver has a problem in this area as it does not put it into an int  but
into a char. Let's see :

from drivers/char/lp.c : lp_ioctl :
    int status
    copy_to_user((int *) arg, &status, sizeof(int))

from drivers/usb/printer.c : usblp_ioctl :
    unsigned char status;
    copy_to_user ((unsigned char *)arg, &status, 1)

Even though in  most  cases  it  can  work  unnoticed  on  little-endian
machines ;o), it's broken on non-little-endian machines (I got bitten on
PPC).

this saves memory by making the buffer for firmware temporary.

Here's a followup patch, should apply on top of what I sent
this morning ... please do so!  (Sorry, same name but the
patch is different.)

Along with some cleanups, this actually restores a line that
was dropped somewhere in 2.5 ... basically, at least SiS and
OPTi violate the OHCI spec so they don't init "by the book".

  
removed __devinitdata and __devinit on structures and functions that should
not have them.
Thanks to Tom Rini for pointing this out.

I tracked down some of those "can't enumerate" problems to a
chip init problem.  This patch detects and reports that case
(better than the current nasty failure mode, and worth keeping
even after we have a fix that works on OPTi/SiS/...) as well as
doing some other minor cleanup.

	This patch  fixes the Compaq WL210 problems I've been having.

The symptoms were that no interupts were ever received from the card;
the BIOS reported it had assigned INTA to IRQ 10; but the yenta
driver reported IRQ 17.

The fix is not to rely on the BIOS's initialisation of interrupt
routing in the TI1410, but to do it explicitly.

This may break laptops that actually use the parallel ISA IRQ
mechanism.

on non-x86 architectures)

in structures and unions (and why not other variables too..)

Many old ISA drivers are not 64bit clean. To avoid dealing with them on
x86-64 I guarded them with CONFIG_ISA. This is also helpful for other
archs (including modern x86) that do not have ISA slots anymore.
The patch has been reviewed by Linux-Kernel, with some additional
cleanups by me. It misses some directories like ISDN or sound drivers.

This fixes a potential security issue on i386. FXRSTOR raises an #GP
when the MXCSR field in the FXSAVE frame contains illegal values. By
putting an signal frame just at a border to an unmapped page a malicious
user could potentially cause an exception in the context switch using this.
When the EFAULT occurs in the last bytes of the signal frame the MXCSR
check would be skipped in the old code, but the rogue value would be already
in task_struct, causing problems later.

Here is the minimal fix for this.

Originally discovered by Andrea while doing x86-64 work. It was fixed in
a different way a bit more intrusive way on x86-64 - all FXRSTOR in the
kernel are guarded by exception handlers.

It's nearly impossible to get the correct CPU names for AMD CPUs in
the MP table (would need BIOS calls etc.). The decoding of CPU names form
the mptable doesn't look too useful anyways, because the correct CPU name
from CPUID is printed only a few lines later. This patch just removes
the name table and replaces it with a printout of the hex value.
This mirrors a change in x86-64

Remove myself as networking maintainer. I haven't done much for networking
for a long time and it doesn't look likely it'll change anytime soon.
Also David/Alexey are doing a fine job without me.

Here is the big 2.5.21 x86-64 sync patch. It only touches arch/x86_64
and include/asm-x86_64. It requires a few other changes that I'm sending
in separate mail.

Changes:
- merge wit 2.5.21
- merge from 2.5.21/i386 (new PCI code, new LDT code etc.)
- sync with 2.4-x86_64 tree.
- minor updates to 32bit emulation
- better early console; including serial support.
- now set up dummy PDA for booting to avoid problems
- Fix GS reloading in context switch one instruction race
- Remove hardcoded names from mpparse code
- Fix inline assembly for RAID-5 xor (similar change needed for i386)
- Real per cpu data support based on PDA field
- Cleanup of offset.c generation requested by Kai: it only puts structure
  offsets into offset.h now.
- Fix i387 fxsave signal frame problems.
- Add uname emulation via personality ("linux32")
- New SSE optimized checksum-copy, copy*user, memcpy, clear_page, copy_page
  functions. Other tunings/cleanups in checksum and other user memory
  access function.
- check if exception table is really sorted
- Cleanups in page table handling in preparation of non executable pages
  support.
- Cleanup PDA access to not require offset.h (thanks to kai for kicking me
  to this)
- use long long for u64/s64 to avoid more warnings
- remove CONFIG_ISA
- fix various bugs and other cleanups

Recent header cleanup broke this driver. Needs #include <linux/init.h>

Change non-interpreter code to account for the interpreter changes.

This update gets things compiling again after a device model change.

end_request(int) turned to end_request(req, int); all old callers
are converted to end_request(CURRENT, value).  Now we can start
killing CURRENT/QUEUE - end_request() was the last obstacle to
that.

ditto for DEVICE_INTR/CLEAR_INTR.  do_mfm/do_acsi/do_hd/... are
explicitly declared in the drivers that use DEVICE_INTR stuff;
DEVICE_INTR/CLEAR_INTR is gone from blk.h.

#define DEVICE_NAME ... removed from the drivers that never use
that macro.

monstrous cascade of #ifdefs is gone from blk.h.  This is the first
step of cleanup - we move #define in question into the code that
includes blk.h (i.e. DEVICE_NR, DEVICE_NAME and DEVICE_INTR are
explicitly set by drivers).

->s_dev is switched to dev_t.  Everything that uses it uses it as
a number - i.e. all instances are either minor() or kdev_t_to_nr().
