[PATCH] bcm43xx: Fix cancellation of work queue crashes
A crash upon booting that is caused by bcm43xx has been reported [1] and
found to be due to a work queue being reinitialized while work on that
queue is still pending. This fix modifies the shutdown of work queues and
prevents periodic work from being requeued during shutdown. With this patch,
no more crashes on reboot were observed by the original reporter. I do not
get that particular failure on my system; however, when running a large
number of ifdown/ifup sequences, my system would kernel panic with the
'caps lock' light blinking at roughly a 1 Hz rate. In addition, there were
infrequent failures in the firmware that resulted in 'IRQ READY TIMEOUT'
errors. With this patch, no more of the first type of failure occur, and
incidence of the second type is greatly reduced.

Fix race with shared tag queue maps
There's a race condition in blk_queue_end_tag() for shared tag maps,
users include stex (promise supertrak thingy) and qla2xxx. The former
at least has reported bugs in this area, not sure why we haven't seen
any for the latter. It could be because the window is narrow and that
other conditions in the qla2xxx code hide this. It's a real bug,
though, as the stex smp users can attest.
We need to ensure two things - the tag bit clearing needs to happen
AFTER we cleared the tag pointer, as the tag bit clearing/setting is
what protects this map. Secondly, we need to ensure that the visibility
of the tag pointer and tag bit clear are ordered properly.

spidernet: fix interrupt reason recognition
This patch solves a problem that the spidernet driver sometimes fails
to handle IRQ.
The problem happens because,
- In Cell architecture, interrupts may arrive at an interrupt
controller, even if they are masked by the setting on registers of
devices. It happens when interrupt packets are sent just before
the interrupts are masked.
- spidernet interrupt handler compares interrupt reasons with
interrupt masks, so when such interrupts occurs, spidernet interrupt
handler returns IRQ_NONE.
- When all of interrupt handler return IRQ_NONE, linux kernel disables
the IRQ and it no longer delivers interrupts to the interrupt handlers.
spidernet doesn't work after above sequence, because it can't receive
interrupts.
This patch changes spidernet interrupt handler that it compares
interrupt reason with SPIDER_NET_INTX_MASK_VALUE.

Define termios_1 functions for powerpc, s390, avr32 and frv
Commit
f629307c857c030d5a3dd777fee37c8bb395e171 introduced uses of
kernel_termios_to_user_termios_1 and user_termios_to_kernel_termios_1

currently define those functions since their termios struct didn't
need to be changed when the arbitrary baud rate stuff was added, and
thus the kernel won't currently build on those architectures.
This adds definitions of kernel_termios_to_user_termios_1 and
user_termios_to_kernel_termios_1 to include/asm-generic/termios.h
which are identical to kernel_termios_to_user_termios and
user_termios_to_kernel_termios respectively. The definitions are the
same because the "old" termios and "new" termios are in fact the same
on these architectures (which are the same ones that use
asm-generic/termios.h).

Currently we simply add the debug flags unconditional when checking for a
matching slab. This creates issues for sysfs processing when slabs exist
that are exempt from debugging due to their huge size or because only a
subset of slabs was selected for debugging.
We need to only add the flags if kmem_cache_open() would also add them.
Create a function to calculate the flags that would be set
if the cache would be opened and use that function to determine
the flags before looking for a compatible slab.

Catch illegally nested kmap_atomic()s even if the page that is mapped by

This avoids spuriously zapped kmap-atomic ptes and turns hard to find
crashes into clear asserts at the bug site.
Problem is, a get_zeroed_page(GFP_KERNEL) from interrupt context will trigger
this check if non-irq code on this CPU holds a KM_USER0 mapping. But that
get_zeroed_page() will never be altering the kmap slot anyway due to the
GFP_KERNEL.

Leases can be hidden by flocks
The inode->i_flock list contains the leases, flocks and posix

Restore call_usermodehelper_pipe() behaviour
The semantics of call_usermodehelper_pipe() used to be that it would fork
the helper, and wait for the kernel thread to be started. This was
implemented by setting sub_info.wait to 0 (implicitly), and doing a
wait_for_completion().
As part of the cleanup done in
0ab4dc92278a0f3816e486d6350c6652a72e06c8,
call_usermodehelper_pipe() was changed to pass 1 as the value for wait to
call_usermodehelper_exec().
This is equivalent to setting sub_info.wait to 1, which is a change from
the previous behaviour. Using 1 instead of 0 causes
__call_usermodehelper() to start the kernel thread running
wait_for_helper(), rather than directly calling ____call_usermodehelper().
The end result is that the calling kernel code blocks until the user mode
helper finishes. As the helper is expecting input on stdin, and now no one
is writing anything, everything locks up (observed in do_coredump).
The fix is to change the 1 to UMH_WAIT_EXEC (aka 0), indicating that we
want to wait for the kernel thread to be started, but not for the helper to
finish.

return 0;
This is going to write over the end of the userspace
structure by a few bytes, and wasn't caught by you yet
because the i386 implementation is simply copy_to_user()
which does zero type checking.

futex_compat: fix list traversal bugs
The futex list traversal on the compat side appears to have
a bug.
It's loop termination condition compares:
while (compat_ptr(uentry) != &head->list)
But that can't be right because "uentry" has the special
"pi" indicator bit still potentially set at bit 0. This
is cleared by fetch_robust_entry() into the "entry"
return value.
What this seems to mean is that the list won't terminate
when list iteration gets back to the the head. And we'll
also process the list head like a normal entry, which could
cause all kinds of problems.
So we should check for equality with "entry". That pointer
is of the non-compat type so we have to do a little casting
to keep the compiler and sparse happy.
The same problem can in theory occur with the 'pending'
variable, although that has not been reported from users
so far.
Based on the original patch from David Miller.

hpt366: UltraDMA filter for SATA cards (take 2)
The Marvell bridge chips used on HighPoint SATA cards do not seem to support
the UltraDMA modes 1, 2, and 3 as well as any MWDMA modes, so the driver needs
to account for this in the udma_filter() method. In order to achieve that, do
the following changes:
- install the method for all chips, not only HPT36x/370 and improve the code
formatting by killing the extra tabs while at it;
- add to the end of the 'switch' statement in the method cases for HPT372[AN]
and HPT374 chips upon which the known SATA cards are based;
- use hwif->ultra_mask as a default mask for the ide_dma_filter() method to
behave correctly;
- move the HPT370[A] cases below the HPT36x case for consistency.
While at it, replace the explicit UltraDMA mode masks with ATA_UDMA* constants
all over the driver...
