Previously inet devices were only constructed when addresses are added
(or rarely in ipmr). Therefore the default config values they get are
the ones at the time of these operations.Now that we're creating inet devices earlier, this changes the
behaviour of default config values in an incompatible way (see bug
#8519).This patch creates a compromise by setting the default values at the
same point as before but only for those that have not been explicitly
set by the user since the inet device's creation.Signed-off-by: Herbert Xu

Previously once inetdev_init has been called on a device any changes
made to ipv4_devconf_dflt would have no effect on that device's
configuration.This creates a problem since we have moved the point where
inetdev_init is called from when an address is added to where the
device is registered.This patch is the first half of a set that tries to mimic the old
behaviour while still calling inetdev_init.It propagates any changes to ipv4_devconf_dflt to those devices that
have not had the corresponding attribute set.The next patch will forcibly set all values at the point where
inetdev_init was previously called.Signed-off-by: Herbert Xu

This patch converts the ipv4_devconf config members (everything except
sysctl) to an array. This allows easier manipulation which will be
needed later on to provide better management of default config values.Signed-off-by: Herbert Xu

When I made the inetdev_init call work on all devices I incorrectly
left in the panic call as well. It is obviously undesirable to
panic on an allocation failure for a normal network device. This
patch moves the panic call under the loopback if clause.Signed-off-by: Herbert Xu

A time_wait socket inherits sk_bound_dev_if from the original socket,
but it is not used when sending ACK packets using ip_send_reply.Fix by passing the oif to ip_send_reply in struct ip_reply_arg and
use it for output routing.Signed-off-by: Patrick McHardy

The statistics block DMA on 5708 can be messed up occasionally on the
average of about once per hour. If the user is reading the counters
within one second after the corruption, the counters will be all
messed up. One second later, the counters will be ok again until the
next corruption occurs.The workaround is to disable the periodic statistics DMA. Instead,
we manually trigger the DMA once a second in bnx2_timer(). This
manual trigger of the DMA avoids the problem.As a consequence, we can only allow 0 or 1 second settings for
ethtool -C statistics block.Thanks to Jean-Daniel Pauget and
CaT for reporting this rare problem.Signed-off-by: Michael Chan

For correctness, we need to wait for the MEM_INIT bit to be cleared

There's a bug in the driver that only initializes half of the context
memory on the 5708. Surprisingly, this works most of the time except
for some occasional netdev watchdogs when sending a lot of 64-byte
packets. The fix is to add the missing code to initialize the 2nd
halves of all context memory.Signed-off-by: Michael Chan

This patch should get a few birds. It prevents sigaction calls from
clearing TIF_SIGPENDING in other threads, which could leak -ERESTART*.
And It fixes ptrace_stop not to clear it, which done at the syscall exit
stop could leak -ERESTART*. It probably removes the harm from signalfd,
at least assuming it never calls dequeue_signal on kernel threads that
might have used block_all_signals.Signed-off-by: Roland McGrath

The COFF zImage (for booting oldworld powermacs) wasn't being built
correctly because the procedure descriptor in crt0.S for the zImage
entry point wasn't declared as .globl, and therefore wasn't getting
pulled in from wrapper.a by the linker. This adds the necessary
.globl statement.Signed-off-by: Paul Mackerras

The error path in spufs_fill_dir() is broken. If d_alloc_name() or
spufs_new_file() fails, spufs_prune_dir() is getting called. At this time
dir->inode is not set and a NULL pointer is dereferenced by mutex_lock().
This bugfix replaces spufs_prune_dir() with a shorter version that does
not touch dir->inode but simply removes all children.Signed-off-by: Sebastian Siewior

We had a problem on a system with only dynamically allocated
PCI buses (using of_pci_phb_driver) in combination with libata.
This setup ended up having no "primary" phb, which means
that pci_io_base never got initialized and all IO port
numbers are 64 bit numbers, which is larger than the
PIO_MASK limit.Signed-off-by: Arnd Bergmann

Fix the race between checking for contexts on the runqueue and actually
waking them in spu_deactive and spu_yield.The guts of spu_reschedule are split into a new helper called
grab_runnable_context which shows if there is a runnable thread below
a specified priority and if yes removes if from the runqueue and uses
it. This function is used by the new __spu_deactivate hepler shared
by preemption and spu_yield to grab a new context before deactivating
a specified priority and if yes removes if from the runqueue and uses
it. This function is used by the new __spu_deactivate hepler shared
by preemption and spu_yield to grab a new context before deactivating
the old one.Signed-off-by: Christoph Hellwig

Previously, closing a SPE gang that still has contexts would trigger
a WARN_ON, and leak the allocated gang.This change fixes the problem by using the gang's reference counts to
destroy the gang instead. The gangs will persist until their last
reference (be it context or open file handle) is gone.Also, avoid using statements with side-effects in a WARN_ON().

references promfont_unitable and promfont_unicount which are marked
__initdata by the conmakehash command in the drivers/video/console/MakefileFix the warning by removing the __initdata marker on the two variables.
