loop_init doesn't fail gracefully for two reasons:

1) If initialization of loop driver fails, we have an call to
   devfs_add("loop") without any devfs_remove; I add that.

2) On lwn.net 2.6 kernel docs, Jonathan Corbet says: "If you are calling
   add_disk() in your driver initialization routine, you should not fail
   the initialization process after the first call."

So I make loop.c conform to this request by moving add_disk after all
memory allocations.

One more patch --- this fixes a minor bio handling bug in the filebacked
code path. I'd fixed it incidentally in the loop-recycle patch.

I don't think you could actually see damage from this bug unless you
run device mapper on top of loop devices, but still this is the correct
behavior.

From: Ben Slusky <sluskyb@paranoiacs.org>

The attached patch changes the loop device transfer functions (including
cryptoloop transfers) to accept page/offset pairs instead of virtual
addresses, and removes the redundant kmaps in do_lo_send, do_lo_receive,
and loop_transfer_bio. Per Andrew Morton's request a while back.

This patch removes the loop feature wherein we remap BIOs for block-backed
loop.  So file-backed and block-backed loop are handled identically.

It cleans up the code a lot and fixes the low-on-memory lockups which
block-backed loop currently suffers.

What we lose is the journalling ordering guarantees which
exts-on-loop-on-blockdev had.  But dm-crypt provides that.

This patch lets 2.6.3-rc4 build and boot on an PPC64 iSeries box (at least
for my configuration).  The veth.o bit in the networking Makefile got there
by accident and should be removed anyway ...

There is more to make it work properly (note the "Temporary hack"), but
this gets us closer.

Fix compile warnings and add some type safety to debugger macros.

cmd_line was twice the size of saved_command_line but we did a strcpy from
the larger into the smaller.  Create COMMAND_LINE_SIZE and use it.

msg.h uses list_head.  (I'm not sure what config actually required this, but
it is legit).

These no longer do anything.

This patch changes modules API.  It was acked by Arjan@RH and Hubert@Suse.

- Use __pa() around the VGA base address: more friendly for the 4g/4g split.

- Use cpu_relax() rather than open-coding rep_nop().

- Default to 9600 baud

- Move documentation to Documentation/kernel-parameters.txt

- Make CONFIG_EARLY_PRINTK disableable if CONFIG_EMBEDDED

I found a bug in the PPPIOCSPASS PPPIOCSACTIVE IOCTL implementation in
kernel 2.5/2.6.

The current pppd code use a empty filter (uprog.len=0) to detach the filter
in the kernel, but this code was removed in 2.5.71 while fixing a compiler
warning.

Here the new patch, also with better limit checking.

The second patch check for flen == 0 in the filter check too, since later
in this code a filter[flen - 1] access is done, which is not so funny with
flen 0.  Maybe it's not really needed anymore, since with the first patch
it would not longer called with flen=0.

paulus says:

    It looks correct.  Previously we had (and in 2.4 we still have)

        if (uprog.len > 0 && uprog.len < 65536) {
		...

    which gave warnings since uprog.len is unsigned short.  So someone
    decided that both parts of the condition were redundant.

This patch fix a deadlock in HiSax (reported from David Woodhouse
<dwmw2@infradead.org>).  upper layer was called back while holding the card
lock fix is to move the wakeup call into BH handler to avoid direct
callbacks.

From: Karsten Keil <kkeil@suse.de>

- new port of 2.4 I4L core to 2.6

- new port of 2.4 I4L HiSax to 2.6

- fixes for I4L CAPI subsystem to make it stable in 2.6

- fix parameter handling of AVM ISA cards (calle)

- cleanup ISDN config variables

- SMP in act2000 and pcbit driver

- remove check_region in act2000

- mark hysdn, isdnloop and divert as BROKEN_ON_SMP

Tx descriptor overflow - take II.

Assume tp->dirty_tx = NUM_TX_DESC/2, tp->cur_tx = NUM_TX_DESC - 1,
watch "entry" go beyond NUM_TX_DESC. Actually this is where the same
bug in r8169 driver comes from.

The transmit routine will stop interrupting and hang, causing the
tx_timeout routine to attempt to restart the device when the 32-bit
cur_tx counter wraps below dirty_tx.  If the device had called
netif_stop_queue it will never call netif_wake_queue in the interrupt
routine (at least on an IA32 system) due to 32-bit wrap around arithmetic.

On my IA32 system 'dirty_tx > lp->cur_tx - TX_RING_SIZE + 2' would
always evaluate to false when dirty and cur_tx were less than 15,
preventing netif_wake_queue to be called.

By starting dirty_tx and cur_tx at 0xfffffff0 (to reduce test time) I
found that once cur_tx wrapped to zero, that transmitted buffers would
never be unmapped or freed because 'while (dirty_tx < lp->cur_tx) {'
was not true.  cur_tx would keep incrementing (in start_xmit) but dirty_tx
would not (in pcnet32_interrupt), thus leaking skb's and pci map entries.
On PPC machines, the system would quickly run out of pci maps.

Fix tested on PPC and IA32.

description:      remove double semi-colon typo;

Add capability to tag self generated ARP packets that are required
for receive load balancing in bonding. VLAN Id's are saved and used
each time a new IP connection is established since 8021q currently
supports IP binding.

Update module version and comment blocks.

Add capability to tag self generated learning packets that are
required to speed up port selection in the switch after a fail
over in bonding since some switches will only update their MAC
tables from tagged packets when VLAN support is turned on. All
VLAN Id's that have been configured on top of the bond interface
will be used in cyclic order.

Now that David Miller accepted the first half of this set into 2.6,
I'm resending the last half to you for inclusion in netdev-2.6.

Tested against latest netdev-2.6. Summary:

Change the bond interface to publish full VLAN hardware acceleration
offloading capabilities, and add capability in all xmit functions to
take special care for VLAN HW accel. tagged skb's that are going out
through a slave that is not offloading capable.

Add a mechanism to collect and save the VLAN Id's that have been
added on top of a bond interface, and propagate the register/add/kill
operations to the slaves.

Add blocking mechanism to prevent adding VLAN interfaces on top of a
bond that contains VLAN challenged slaves and to prevent adding VLAN
challenged slaves to a bond that already has VLAN interfaces on top
of it.

Add a section about VLAN to Documentation/networking/bonding.txt and
also correct some minor spelling/grammer errors.

This patch is the same as to mkiss a while ago, the current code triggers a
bug when reattaching a network device.

The pcnet32 driver uses the incorrect length (of zero) in
pci_[un]map_single for receive buffers.  This is seen with SLAB_DEBUG
enabled.

Tested in IA32 system.  If this patch is not applied after my previous
one hunks #1, #3, and #5 will have an offset of -2 lines.

This should fix the problem... The multi-bus probe logic error handling was

He validated it; so please apply

Here is the first of several individual patches to 2.6.3 for the pcnet32
driver.

The driver did not properly serialize accesses to chip registers, resulting
in reading/writing the wrong register.  This patch eliminates this problem
and gets rid of the cause of the symptom of 'bus master arbitration failure'.

It was easier to use generic_mii_ioctl than modify the current pcnet32_ioctl
routine with the necessary locks.  This has been re-tested on an IA32 system.

is a bit unforgiving and really doesn't like 64-bit values.

We should possibly make wrmsr() automatically truncate the
arguments, but regardless we should just fix microcode.c.
