df8dc74e8a Merge git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-2.6
This can be broken down into these major areas:
 - Documentation updates (language translations and fixes, as
   well as kobject and kset documenatation updates.)
 - major kset/kobject/ktype rework and fixes.  This cleans up the
   kset and kobject and ktype relationship and architecture,
   making sense of things now, and good documenation and samples
   are provided for others to use.  Also the attributes for
   kobjects are much easier to handle now.  This cleaned up a LOT
   of code all through the kernel, making kobjects easier to use
   if you want to.
 - struct bus_type has been reworked to now handle the lifetime
   rules properly, as the kobject is properly dynamic.
 - struct driver has also been reworked, and now the lifetime
   issues are resolved.
 - the block subsystem has been converted to use struct device
   now, and not "raw" kobjects.  This patch has been in the -mm
   tree for over a year now, and finally all the issues are
   worked out with it.  Older distros now properly work with new
   kernels, and no userspace updates are needed at all.
 - nozomi driver is added.  This has also been in -mm for a long
   time, and many people have asked for it to go in.  It is now
   in good enough shape to do so.
 - lots of class_device conversions to use struct device instead.
   The tree is almost all cleaned up now, only SCSI and IB is the
   remaining code to fix up...

7fde4d779b [ISDN]: i4l: Fix DLE handling for i4l-audio
The DLE handling in i4l-audio seems to be broken.

It produces spurious DLEs so asterisk 1.2.24 with chan_modem_i4l
gets irritated, the error message is:
"chan_modem_i4l.c:450 i4l_read: Value of escape is ^ (17)".
-> There shouldn't be a DLE-^.
If a spurious DLE-ETX occurs, the audio connection even dies.
I use a "AVM Fritz!PCI" isdn card.

I found two issues that only appear if ISDN_AUDIO_SKB_DLECOUNT(skb) > 0:
- The loop in isdn_tty.c:isdn_tty_try_read() doesn't escape a DLE if it's
  the last character.

- The loop in isdn_common.c:isdn_readbchan_tty() doesn't copy its characters,
  it only remembers the last one ("last = *p;").

  Compare it with the loop in isdn_common.c:isdn_readbchan(), that *does*
  copy them ("*cp++ = *p;") correctly.
  The special handling of the "last" character made it more difficult.
  I compared it to linux-2.4.19: There was no "last"-handling and both loops
  did escape and copy all characters correctly.

00409bb045 [ISDN] i4l: 'NO CARRIER' message lost after ldisc flush
The ISDN tty layer doesn't produce a 'NO CARRIER' message after hangup.

I suppose it broke when tty_buffer_flush() has been added to
tty_ldisc_flush() in the commit below.

For isdn_tty_modem_result(RESULT_NO_CARRIER..) the
message inserted via isdn_tty_at_cout() -> tty_insert_flip_char()
is flushed immediately by tty_ldisc_flush() -> tty_buffer_flush().
More annoyingly, the audio abort sequence DLE-ETX is also lost.

This patch fixes only active audio connections, because I assume that nobody
changes the line discipline for audio.

For non-audio connections the problem remains.
Maybe we can remove the tty_ldisc_flush() in isdn_tty_modem_result()
at all because it's done at tty_close?

 Kernel panic - not syncing: Attempted to kill init!

The box has no HiSax card installed.

the reason for the crash is add_timer() done on an already running
timer. This happens because for some reason CARD_INIT is called twice.

this patch works this problem around by using mod_timer() - this gets
a booting system - but it would be nice to figure out why CARD_INIT
is done twice.

1ccfd63367 i4l: Fix random hard freeze with AVM c4 card
The patch
- Includes the call to capilib_data_b3_req in the spinlock. This routine
  in turn calls the offending mq_enqueue routine that triggered the
  freeze if not locked.  This should also fix other indicators of
  incosistent capilib_msgidqueue list, that trigger messages like:
  Oct  5 03:05:57 BERL0 kernel: kcapi: msgid 3019 ncci 0x30301 not on queue
  that we saw several times a day (usually several in a row).
- Fixes all occurrences of c4_dispatch_tx to be called with active
  spinlock, there were some instances where no lock was active. Mostly
  these are in very infrequently called routines, so the additional
  performance penalty is minimal.

This patch extends the existing locking to the calls of these function to

b1b2e7cf4a fix possible NULL deref on low memory condition in capidrv.c::send_message()
If we fail to allocate an skb in
drivers/isdn/capi/capidrv.c::send_message(), then we'll end up
dereferencing a NULL pointer.
Since out of memory conditions are not unheard of, I believe it
is better to print a error message and just return rather than
bring down the whole kernel.
Sure, doing this may upset some application, but that's still
better than crashing the whole system.

457c4cbc5a [NET]: Make /proc/net per network namespace
This patch makes /proc/net per network namespace.  It modifies the global
variables proc_net and proc_net_stat to be per network namespace.
The proc_net file helpers are modified to take a network namespace argument,
and all of their callers are fixed to pass &init_net for that argument.
This ensures that all of the /proc/net files are only visible and
usable in the initial network namespace until the code behind them
has been updated to be handle multiple network namespaces.

Making /proc/net per namespace is necessary as at least some files
in /proc/net depend upon the set of network devices which is per
network namespace, and even more files in /proc/net have contents
that are relevant to a single network namespace.

9ee0be05dc ISDN HiSax: uninitialized return in hisax_cs_setup
Coverity (1792) spotted a possibly uninitialized return value in case of
kmalloc() failure:

1116 static int hisax_cs_setup(int cardnr, struct IsdnCard *card,
1117                           struct IsdnCardState *cs)
1119         int ret;
1120
1121         if (!(cs->rcvbuf = kmalloc(MAX_DFRAME_LEN_L1, GFP_ATOMIC))) {
1122                 printk(KERN_WARNING "HiSax: No memory for isac rcvbuf\n");
1123                 ll_unload(cs);
1124                 goto outf_cs;
...
1165 outf_cs:
1166         kfree(cs);
1167         card->cs = NULL;
1168         return ret;

The straightforward solution would be to just add the missing
initialization but hardcoding the return value in the out_cs branch
(only taken on failure) seems to work just as well and it allows killing
a couple of other lines too.

drivers/isdn/capi/capi.c: In function 'handle_minor_send':
drivers/isdn/capi/capi.c:552: warning: cast from pointer to integer of different size

Of course, the code here might actually be buggy, in which case this patch
should not be applied?

Answer:

  No this field is ignored inside linux kernel.Yes this is ugly, but it's
  the CAPI spec for all OS.

  CAPI DATA_B3 Request/Indication CAPI Message has a mandatory field which
  represent the 32 bit buffer address of the payload data.  In linux the
  payload data do not use a sperate buffer, data follows directely after the
  CAPI Message in the same skb and we use this assumption inside the drivers,
  so we can ignore this field.

  Inside the linux CAPI implemetation we never use this field, so it could
  also have no value, but since random data in a message is bad as well (e.g.
  displayed in CAPI traces) we set is to the most adequate value.

  Outside the kernel the capi20 library sets the correct addresses (there is
  an optional second field for 64 bit adresses for 64 bit systems, we do not
  use here).

44c10138fd PCI: Change all drivers to use pci_device->revision
Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.

This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.

In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.

Compile tested with make all{yes,mod}config on x86_64 and i386.

e8edc6e03a Detach sched.h from mm.h
First thing mm.h does is including sched.h solely for can_do_mlock() inline
function which has "current" dereference inside. By dealing with can_do_mlock()
mm.h can be detached from sched.h which is good. See below, why.

This patch
a) removes unconditional inclusion of sched.h from mm.h
b) makes can_do_mlock() normal function in mm/mlock.c
c) exports can_do_mlock() to not break compilation
d) adds sched.h inclusions back to files that were getting it indirectly.
e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were
   getting them indirectly

Net result is:
a) mm.h users would get less code to open, read, preprocess, parse, ... if
   they don't need sched.h
b) sched.h stops being dependency for significant number of files:
   on x86_64 allmodconfig touching sched.h results in recompile of 4083 files,
   after patch it's only 3744 (-8.3%).

Cross-compile tested on

	all arm defconfigs, all mips defconfigs, all powerpc defconfigs,
	alpha alpha-up
	arm
	i386 i386-up i386-defconfig i386-allnoconfig
	ia64 ia64-up
	m68k
	mips
	parisc parisc-up
	powerpc powerpc-up
	s390 s390-up

	sparc64 sparc64-up
	um-x86_64
	x86_64 x86_64-up x86_64-defconfig x86_64-allnoconfig

as well as my two usual configs.

6473d160b4 PCI: Cleanup the includes of <linux/pci.h>
I noticed that many source files include <linux/pci.h> while they do
not appear to need it. Here is an attempt to clean it all up.

In order to find all possibly affected files, I searched for all
files including <linux/pci.h> but without any other occurence of "pci"
or "PCI". I removed the include statement from all of these, then I
compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
false positives manually.

My tests covered 66% of the affected files, so there could be false
positives remaining. Untested files are:

I would welcome test reports for these files. I am fine with removing
the untested files from the patch if the general opinion is that these
changes aren't safe. The tested part would still be nice to have.

:-)

Many calculations that previously required that skb->{transport,network,
