bonding: modify sysfs support to permit multiple loads
The existing code would blindly attempt to create the
bonding_masters file (in /sys/class/net) every time the module was
loaded. When the module is loaded multiple times (which is the
historical method used by initscripts and sysconfig to create multiple
bonding interfaces), this caused load failure of the second module load
attempt, as the creation request would fail.
This changes the code to note the failure, arrange to not remove
the bonding_masters file upon module exit, and then return success.
Bonding interfaces created by the second or subsequent loads of
the module will not exist in bonding_masters. This is not a significant
change, as previously only the interfaces from the most recent load of
the module would be listed. Both situations are less than optimal, but
this case permits compatibility with existing distro configuration
scripts, and is consistent.
Note that previously, the sysfs create request would overwrite
the exsting bonding_masters file and succeed, allowing multiple loads of
the module. The sysfs code has recently changed to return an error if
the file being created already exists.
Patrick McHardy <kaber@trash.net>, who reported this problem,
observed crashes on the old kernel (before sysfs checked for
duplicates). I did not experience such crashes, but this change should
resolve them.

driver for Silan SC92031 netdev
This is a driver for the Silan SC92031/Rsltek 8139D NIC chip.
This chip is found on at least one counterfeit Encore ENL832-TX-RENT NIC
[1], which came with a mini-CD with the 2.4 driver. A slightly older
version of the driver was found at [2]. The main difference between them
is that the newer one has a small bugfix in the RX path, a lot of
gratuitous renaming of functions, all the printable strings changed to show
as a "Rsltek 8139D" [sic], and a PCI ID of 8139 instead of 2031. The
driver on this patch is a rewrite of the vendor drivers (based mostly on
the older one).
Changes from the previous patch sent to netdev:
- Use MMIO instead of PIO
- Changed TX bounce buffers allocation
- Use skb_copy_and_csum_dev
- Several small bug fixes
- Tested for more than just a few minutes each time

[PATCH] zd1211rw: Remove addressing abstraction
Instead of passing our own custom 32-bit addresses around and
translating them, this patch makes all our register address constants
absolute and removes the translation.
There are two ugly parts:
- fw_reg_addr() is needed to compute addresses of firmware registers, as this
is dynamic based upon firmware
- inc_addr() needs a small hack to handle byte vs word addressing
However, both of those are only small, and we don't use fw_regs a whole
lot anyway.
The bonuses here include simplicity and improved driver readability. Also, the
fact that registers are now referenced by 16-bit absolute addresses (as
opposed to 32-bit pseudo addresses) means that over 2kb compiled code size has
been shaved off.
Includes some touchups and sparse fixes from Ulrich Kunitz.

[PATCH] zd1211rw: Consistency for address space constants
The zd1211rw address space has confused me once too many times. This
patch introduces the following naming notation:
Memory space is split into segments (cr, fw, eeprom) and segments may
contain components (e.g. boot code inside eeprom). These names are
arbitrary and only for the description below:
x_START: Absolute address of segment start
(previously these were named such as CR_BASE_OFFSET, but they weren't
really offsets unless you were considering them as an offset to 0)
x_LEN: Segment length
x_y_LEN: Length of component y of segment x
x_y_OFFSET: Relative address of component y into segment x. The absolute
address for this component is (x_START + x_y_OFFSET)
I also renamed EEPROM registers to EEPROM data. These 'registers' can't
be written to using standard I/O and really represent predefined data
from the vendor.

[PATCH] kexec: Avoid migration of already disabled irqs (ia64)
This patch fixes up ia64 kexec support for HP rx2620 hardware. It does
this by skipping migration of already disabled irqs. This is most likely a
problem on other ia64 platforms as well, but I've only been able to
reproduce it on one machine so far.
The full story is that handle_bad_irq() gets invoked before starting the
new kernel without this patch. This seems to happen when fixup_irqs()
calls generic_handle_irq() on already migrated (and disabled) irqs. So by
avoiding migration of disabled irqs we stay away of handle_bad_irq().
The code has been tested on three different ia64 machines, all with good
results. It is possible to trigger the same bug by offlining a processor
using echo 0 > /sys/devices/system/cpu/cpuX/online.

flush_workqueue() is not allowed to be called in the softirq context.
However, aio_complete() called from I/O interrupt can potentially call
put_ioctx with last ref count on ioctx and triggers bug. It is simply
incorrect to perform ioctx freeing from aio_complete.
The bug is trigger-able from a race between io_destroy() and aio_complete().
A possible scenario:
cpu0 cpu1
io_destroy aio_complete
wait_for_all_aios { __aio_put_req
... ctx->reqs_active--;
if (!ctx->reqs_active)
return;
}
...
put_ioctx(ioctx)
put_ioctx(ctx);
__put_ioctx
bam! Bug trigger!
The real problem is that the condition check of ctx->reqs_active in
wait_for_all_aios() is incorrect that access to reqs_active is not
being properly protected by spin lock.
This patch adds that protective spin lock, and at the same time removes
all duplicate ref counting for each kiocb as reqs_active is already used
as a ref count for each active ioctx. This also ensures that buggy call
to flush_workqueue() in softirq context is eliminated.

It's not wrong, but it's not right either, and everybody seems to agree
that the right fix is probably to do the ccr3 write after the ccr4 one
(and that we also should clean it up a bit). And after that we need to
really validate that all the bits that we write to ccr4 actually do
work.
The old 2.6.19 code was insane, and basically didn't change ccr4 at all
(even though it certainly looks like it was the *intent* to do so). So
let's revert the change that may fix things, just because it's not what
was actually ever tested when the code was written, even if it _was_ the
intent.
There's a discussion on http://lkml.org/lkml/2007/1/9/63 that was
started by the patch that now gets reverted, and that discussion may
well contain the proper long-term fix.

spidernet : fix memory leak in spider_net_stop
We forget to call spider_net_free_rx_chain_contents which does the
actual dev_kfree_skb. New skbs are allocated from skbuff_head_cache
on each "ifconfig up" letting the cache grow infinitely.
This patch fixes it.

e100: fix napi ifdefs removing needed code

The e100 driver is NAPI mode only. We need to netif_poll_disable
during suspend and shutdown. The non-NAPI driver code was removed
and is only avaiable in the out-of-tree e100 kernel driver.

[NET_SCHED]: act_ipt: fix regression in ipt action
The x_tables patch broke target module autoloading in the ipt action
by replacing the ipt_find_target call (which does autoloading) by
xt_find_target (which doesn't do autoloading). Additionally xt_find_target
may return ERR_PTR values in case of an error, which are not handled.
Use xt_request_find_target, which does both autoloading and ERR_PTR
handling properly. Also don't forget to drop the target module reference
again when xt_check_target fails.

avr32@atmel.com is a technical support address and is not really

I'm still the maintainer of all the entries touched by this patch, so
nothing changes with regard to the "Supported" status of the AVR32

[PATCH] sysrq: showBlockedTasks is sysrq-W
Change SysRq showBlockedTasks from sysrq-X to sysrq-W and show that in the
Help message.
It was previously done via X, but X is already used for Xmon on ppc & powerpc
platforms and this collision needs to be avoided.
All callers of register_sysrq_key() are now marked in the sysrq op/key table.
I didn't mark 'h' as Help because Help is just printed for any unknown key,
such as '?'.
Added some omitted sysrq key entries in the sysrq.txt file.
