Replace inode_setattr with opencoded variants of it in all callers. This
moves the remaining call to vmtruncate into the filesystem methods where it
can be replaced with the proper truncate sequence.
In a few cases it was obvious that we would never end up calling vmtruncate
so it was left out in the opencoded variant:
spufs: explicitly checks for ATTR_SIZE earlier
btrfs,hugetlbfs,logfs,dlmfs: explicitly clears ATTR_SIZE earlier
ufs: contains an opencoded simple_seattr + truncate that sets the filesize just above
In addition to that ncpfs called inode_setattr with handcrafted iattrs,
which allowed to trim down the opencoded variant.

Commit 991ea75c (drm: use workqueue instead of slow-work), which made
drm to use wq instead of slow-work, didn't account for the return
value difference between delayed_slow_work_enqueue() and
queue_delayed_work(). The former returns 0 on success and -errno on
failures while the latter never fails and only uses the return value
to indicate whether the work was already pending or not.
This misconversion triggered spurious error messages. Remove the now
unnecessary return value check and error message.

Based on patches from Sonny Rao and Milton Miller...
Combined the patches to fix up clean_tx_irq and clean_rx_irq.
The PowerPC architecture does not require loads to independent bytes
to be ordered without adding an explicit barrier.
In ixgbe_clean_rx_irq we load the status bit then load the packet data.
With packet split disabled if these loads go out of order we get a
stale packet, but we will notice the bad sequence numbers and drop it.
The problem occurs with packet split enabled where the TCP/IP header
and data are in different descriptors. If the reads go out of order
we may have data that doesn't match the TCP/IP header. Since we use
hardware checksumming this bad data is never verified and it makes it
all the way to the application.
This bug was found during stress testing and adding this barrier has
been shown to fix it. The bug can manifest as a data integrity issue
(bad payload data) or as a BUG in skb_pull().
This was a nasty bug to hunt down, if people agree with the fix I think
it's a candidate for stable.
Previously Submitted to e1000-devel only for ixgbe
http://marc.info/?l=e1000-devel&m=126593062701537&w=3
We've now seen this problem hit with other device drivers (e1000e mostly)
So I'm resubmitting with fixes for other Intel Device Drivers with
similar issues.

Building ixgbe without DCB_CONFIG and FCOE_CONFIG will cause
a build error. This resolves the build error by wrapping
the fcoe.up in CONFIG_IXGBE_DCB ifdefs.
Also frames were being priority VLAN tagged even without DCB
enabled. This fixes this so that 8021Q priority tags are
only added with DCB actually enabled.

Fix up the "generic" unistd.h ABI to be more useful.
There are three reasons to add this support:
1. users probably know the interface type of their flashs, then probe
can be faster if they give the right type in platform data since wrong
types will not be detected.
2. sometimes, detecting can cause destory to system. For example, for
kernel XIP, detecting can cause NOR enter a mode instructions can not
be fetched right, which will make kernel crash.
3. For a new probe which is not listed in the rom_probe_types, if users
assign it in board files, physmap can still probe it.

This patch uses an RCU-inspired approach to fix it. In the RX tasklet's
find_vcc() function we first refuse to use a VCC which already has the
ATM_VF_READY bit cleared. And in the VCC close function, we synchronise
with the tasklet to ensure that it can't still be using the VCC before
we continue and allow the VCC to be destroyed.

Commit 69309a0590 ("x86, asm: Clean up and simplify set_64bit()")
sanitized the x86-64 types to set_64bit(), and incidentally resulted in
warnings like
drivers/pci/intr_remapping.c: In function 'modify_irte':
drivers/pci/intr_remapping.c:314: warning: passing argument 1 of 'set_64bit' from incompatible pointer type
arch/x86/include/asm/cmpxchg_64.h:6: note:expected 'volatile u64 *' but argument is of type 'long unsigned int *'
It turns out that the change to set_64bit() really does clean up things,
and the PCI intr_remapping.c file did a rather ugly cast in order to
avoid warnings with the previous set_64bit() type model.
Removing the ugly cast fixes the warning, and makes everybody happy and
expects a set_64bit() to take the logical "u64 *" argument.

Make /dev/console get initialised before any initialisation routine that
invokes modprobe because if modprobe fails, it's going to want to open
/dev/console, presumably to write an error message to.
The problem with that is that if the /dev/console driver is not yet
initialised, the chardev handler will call request_module() to invoke
modprobe, which will fail, because we never compile /dev/console as a
module.
This will lead to a modprobe loop, showing the following in the kernel
log:
request_module: runaway loop modprobe char-major-5-1
request_module: runaway loop modprobe char-major-5-1
request_module: runaway loop modprobe char-major-5-1
request_module: runaway loop modprobe char-major-5-1
request_module: runaway loop modprobe char-major-5-1
This can happen, for example, when the built in md5 module can't find
the built in cryptomgr module (because the latter fails to initialise).
The md5 module comes before the call to tty_init(), presumably because
'crypto' comes before 'drivers' alphabetically.
Fix this by calling tty_init() from chrdev_init().

This patch moves two functions from .devexit to .text,
which are called on the probe error path.
Also a function which is called by probe is moved
from .text to .devinit.
WARNING: vmlinux.o(.devinit.text+0x2ca5): Section mismatch in reference
from the function via_pci_probe() to the function
devexit.text:via_teardown_subdevs()
The function __devinit via_pci_probe() references
a function __devexit via_teardown_subdevs().
This is often seen when error handling in the init function
uses functionality in the exit path.
The fix is often to remove the __devexit annotation of
via_teardown_subdevs() so it may be used outside an exit section.

Add BUS_NOTIFY_BIND_DRIVER as a bus notifier event.
For driver binding/unbinding we with this in
place have the following bus notifier events:
- BUS_NOTIFY_BIND_DRIVER - before ->probe()
- BUS_NOTIFY_BOUND_DRIVER - after ->probe()
- BUS_NOTIFY_UNBIND_DRIVER - before ->remove()
- BUS_NOTIFY_UNBOUND_DRIVER - after ->remove()
The event BUS_NOTIFY_BIND_DRIVER allows bus code
to be notified that ->probe() is about to be called.
Useful for bus code that needs to setup hardware before
the driver gets to run. With this in place platform
drivers can be loaded and unloaded as modules and the
new BIND event allows bus code to control for instance
device clocks that must be enabled before the driver
can be executed.
Without this patch there is no way for the bus code to
get notified that a modular driver is about to be probed.
