This patch improves error reporting in the configuration parsing routines.
It also adds a few extra minor tweaks.

	#include linux/config.h and make the usual DEBUG settings
	available.

	Use the driver-model dev_xxx() macros for log output.

	Be much more explicit about the nature of errors, including
	configuration, interface, and altsetting numbers where
	appropriate.

	Log fatal problems as errors, non-fatal ones as warnings.

	Remove a #define'd constant that is already set in linux/usb.h.

	Fix some variables declared as pointer to char that really
	should be pointers to unsigned char.

	Replace a whole bunch of "out-of-memory" error messages with
	a single message.

	Wrap source lines that are longer than 80 columns (but not
	log output lines!).

	Clean up the logic for detecting errors when retrieving a
	configuration descriptor.

Apart from the log messages themselves, this introduces no functional
changes.

This adds some code that gadget drivers can call from
driver initialization, to simplify the "configure against
this hardware" step.


Add endpoint autoconfiguration for gadget drivers.

Endpoint selection is currently being done with conditional compilation.
That doesn't look nice, but more importantly it doesn't work well with
the model that some distributions won't be custom-matched to hardware.
Say, a PDA distro running on iPaq (pxa2xx_udc) or Axim (mq11xx_udc).

This code just makes it easier for drivers to match to hardware at
run-time.  It's a convenience function for something they could have
been doing already, but weren't.

adds two more vid/did and better packet error statistics.  Link
detection also has been added.

Here's where all those preceding autoconfig patches start
to fit together:  one gadget driver gets rid of almost all
the controller-specific #ifdeffery.

Two of the other gadget drivers can do the same thing,
and just as easily:  file storage, and serial.  (I'll
hope their maintainers do those changes though.)

The "ether.c" gadget driver is a lot more complicated to
do this way since it has to cope with some differences
by switching to alternate protocols (CDC Ethernet vs
a subset) and soon be able to handle RNDIS.  So that'll
be a while yet.


Gadget Zero learns to autoconfigure.

    - Gets rid of remaining controller-specific #ifdeffery.  Now
      hardware choices can be made at run time too (not just
      compile time).

    - Simplifies its use of the "DEBUG" CPP symbol.

    - Force device to report itself consistently as self-powered.

Correct kernel-doc comment with incorrect parameters documented

we (the german company Gude Analog und Digitalsysteme GmbH,
http://www.gude.info) have manufactored a USB<->RS232 adapter with
galvanic isolated RS232 Interface. Data is transmitted by optical
signals only.

The Product's name is "USB-RS232 OptoBridge".
We used the FTDI 233BM Chip with PID 0xE889 (VID 0x0403).
The Product will be released this Cebit 2004.

Could you please extend the ftdi_sio code with this PID.
You find a .diff file attached which I have tested with kernel 2.6.4

At http://ftdi-usb-sio.sourceforge.net/ I saw that you provide a patch
for 2.4.x kernels. Will our PID also find it's way in this back-ported
driver patch?

In the future (in the next 10 month), our company will have some more
Products using the FTDI Chip. The PID's FTDI already allocated for us
are: E888 to E88F and E808 to E80F


Thank you very much,
   Martin Bachem

x86-64 needs this (obvious) patch, due to the rename.

We can't build floppy.o on ia64, so why bother asking?

Currently SCSI cdroms show up in /proc/partitions in 2.6, they didn't in
2.4.  And ATAPI cdroms don't show up either.  Mark both as genhd removable
for now, when they are partionable this can be updated.

If the drive doesn't support GPCMD_READ_DISC_INFO at all, permit writeable
opens.

Spotted by Jorn Engel <joern@wohnheim.fh-wedel.de>: both the generic and
fs-specific parts of the inode have an i_flags.  find_group_orlov() is using
the wrong one.

strncpy() may not null-terminate the destination.

A smt_snooze_delay of 0 is supposed to mean "disabled", but current idle
loop logic doesn't take that into account and snoozes immediately instead.

Below patch fixes the logic in the idle loop, as well as cleans up the test
a bit.  An idling processor might no longer see a snooze change
immediately, but that's not needed anyway.

With 2.6.4 we now have the glorious hidden d_type passing in getdents.

glibc CVS expects this to be passed if we have a kernel version after
2.6.4, so we have to also handle it in the 32bit syscall converter.

From Dave Miller:

We weren't handling a NULL 'type' argument to mount() properly,
f.e. this happens legitimately when changing the options of an
existing mount.

I stupidly used the global jfs_log_sem to protect log->sb_list when
implementing the shared journal stuff.  Since we already hold
LOG_LOCK, it makes more sense to use that to protect log->sb_list.
This caused horrible serialization when running on lots of jfs
volumes.

Remove the hold_metapage call from txLog to prevent a hang.
While investigating this one, I audited all functions that held
metapage locks and found several error paths that did not release
them correctly.  These are fixed as well.

The patch below fixes issue with 'tc class show dev <dev>' not showing any
classes when TBF qdisc is present in the chain. PLease consider for
inclusion.

Brett E. <brettspamacct@fastclick.com> noticed the missing service lock
for editing dest.

Julian Anastasov <ja@ssi.bg> provided the patch.

This fixes a bug in the swapcontext system call on ppc32.

On ppc32, the system call entry only saves the volatile registers,
except in the case of a few system calls (e.g.  fork) which need all the
registers saved.  Swapcontext needs all the registers but we weren't
saving them all. So fixes that.

At the moment, ppc32 kernels will oops if a threaded program tries to
dump core.  We call dump_fpu with a NULL regs pointer, which it tries
to dereference.

This fixes the issue by implementing the hooks used in doing threaded
core dumps properly.

This fixes the display of the boot messages on the BMAC driver (pmac
only).  It used to be messed up in 2.6

In the long story of "BenH can't get a simple fix right the first time",
please add this one to pmac_zilog, and now people should enjoy really
working sleep again on pmac laptops ...

If the serial port was closed, we could use an uninitialized "pwr_delay"
and pass that to schedule_timeout().

We're getting namespace collisions from the new dma_error(), and it wasn't a
well-chosen identifier.  Rename it to dma_mapping_error().

This is a temporary fix, pending fuller TGA updates.

    drivers/video/tgafb.c is missing a include, complaining about

just a small patch to fix a typo.

From: Petr Baudis <pasky@ucw.cz>

This patch fixes a bug which I hit when migrating from 2.4.  Basically,
when I do setfont during the system boot, the then-spawned ttys do not
retain the new font but fall back to the default one.

I've tracked that down to a clearly bogus test in fbcon_set_display(),
because vc->vc_font.width is not set at that time yet (no font has been
loaded for the new vc).  But even if it would (or this was meant to test
against tmp->vc_font.width), it would mean only *HUGE* fonts would be
retained.  And even if there were *two* bugs there and it was supposed to
be less-than there, I couldn't make a sense of the test.
