Based on original patch and description from Flavio Leitner <fbl@redhat.com>
When bnx2_reset_task() is called, it will stop,
(re)initialize and start the interface to restore
the working condition.
The bnx2_init_nic() calls bnx2_reset_nic() which will
reset the chip and then calls bnx2_free_skbs() to free
all the skbs.
The problem happens when bnx2_init_chip() fails because
bnx2_reset_nic() will just return skipping the ring
initializations at bnx2_init_all_rings(). Later, the
reset task starts the interface again and the system
crashes due a NULL pointer access (no skb in the ring).
To fix it, we call dev_close() if bnx2_init_nic() fails.
One minor wrinkle to deal with is the cancel_work_sync()
call in bnx2_close() to cancel bnx2_reset_task(). The
call will wait forever because it is trying to cancel
itself and the workqueue will be stuck.
Since bnx2_reset_task() holds the rtnl_lock() and checks
for netif_running() before proceeding, there is no need
to cancel bnx2_reset_task() in bnx2_close() even if
bnx2_close() and bnx2_reset_task() are running concurrently.
The rtnl_lock() serializes the 2 calls.
We need to move the cancel_work_sync() call to
bnx2_remove_one() to make sure it is canceled before freeing
the netdev struct.

Function declaration differs between file: dma.c and file:dma.h
and SPARSE (Documentation/sparse.txt) gives error messages
All dma channels are members of 'enum dma_ch' and not 'unsigned int'
Please have a look at channel definitions in:

arch/arm/plat-samsung/include/plat/s3c-dma-pl330.h
arch/arm/mach-s3c2410/include/mach/dma.h
So all arguments should be of type 'enum dma_ch'

Remove Kconfig regression caused by commit
a4616153deae053b29a2b7dd9ec4b2a225accfc5 "watchdog: hpwdt: build hpwdt as
module by default with NMI_DECODING enabled"
With the above change applied, hpwdt will be enabled unconditionally by just
entering the Watchdog subscreen in menuconfig. Since this driver is not
essential to boot any box it should remain disabled until it gets manually
enabled, just like all other drivers.

Add overview documentation in Documentation/ABI/stable/firewire-cdev.
Improve the inline reference documentation in firewire-cdev.h:
- Add /* available since kernel... */ comments to event numbers
consistent with the comments on ioctl numbers.
- Shorten some documentation on an event and an ioctl that are
less interesting to current programming because there are newer
preferable variants.
- Spell Configuration ROM (name of an IEEE 1212 register) in
upper case.
- Move the dummy FW_CDEV_VERSION out of the reader's field of
vision. We should remove it from the header next year or so.

event queuing
Between open(2) of a /dev/fw* and the first FW_CDEV_IOC_GET_INFO
ioctl(2) on it, the kernel already queues FW_CDEV_EVENT_BUS_RESET events
to be read(2) by the client. The get_info ioctl is practically always
issued right away after open, hence this condition only occurs if the
client opens during a bus reset, especially during a rapid series of bus
resets.
The problem with this condition is twofold:
- These bus reset events carry the (as yet undocumented) @closure
value of 0. But it is not the kernel's place to choose closures;
they are privat to the client. E.g., this 0 value forced from the
kernel makes it unsafe for clients to dereference it as a pointer to
a closure object without NULL pointer check.
- It is impossible for clients to determine the relative order of bus
reset events from get_info ioctl(2) versus those from read(2),
except in one way: By comparison of closure values. Again, such a
procedure imposes complexity on clients and reduces freedom in use
of the bus reset closure.
So, change the ABI to suppress queuing of bus reset events before the
first FW_CDEV_IOC_GET_INFO ioctl was issued by the client.
Note, this ABI change cannot be version-controlled. The kernel cannot
distinguish old from new clients before the first FW_CDEV_IOC_GET_INFO
ioctl.
We will try to back-merge this change into currently maintained stable/
longterm series, and we only document the new behaviour. The old
behavior is now considered a kernel bug, which it basically is.

So let's correct this in the <linux/firewire-cdev.h> ABI while it is
still young, relative to distributor adoption.
Side note: We return -ENOTTY not only on _IOC_TYPE or _IOC_NR mismatch,
but also on _IOC_SIZE mismatch. An ioctl with an unsupported size of
argument structure can be seen as an unsupported version of that ioctl.

using struct syscore_ops instead of a sysdev for resume and shutdown.
As a result, this code doesn't build any more after suspend, resume

Fix this problem by converting i8259.c to using syscore_ops.

A system or a device may need to control suspend/wakeup events. It may
want to wakeup the system after a predefined amount of time or at a
predefined event decided while entering suspend for polling or delayed
work. Then, it may want to enter suspend again if its predefined wakeup
condition is the only wakeup reason and there is no outstanding events;
thus, it does not wakeup the userspace unnecessary or unnecessary
devices and keeps suspended as long as possible (saving the power).
Enabling a system to wakeup after a specified time can be easily
achieved by using RTC. However, to enter suspend again immediately
without invoking userland and unrelated devices, we need additional
features in the suspend framework.
Such need comes from:
1. Monitoring a critical device status without interrupts that can
wakeup the system. (in-suspend polling)
An example is ambient temperature monitoring that needs to shut down
the system or a specific device function if it is too hot or cold. The
temperature of a specific device may be needed to be monitored as well;
e.g., a charger monitors battery temperature in order to stop charging
if overheated.
2. Execute critical "delayed work" at suspend.
A driver or a system/board may have a delayed work (or any similar
things) that it wants to execute at the requested time.
For example, some chargers want to check the battery voltage some
time (e.g., 30 seconds) after the battery is fully charged and the
charger has stopped. Then, the charger restarts charging if the voltage
has dropped more than a threshold, which is smaller than "restart-charger"
voltage, which is a threshold to restart charging regardless of the
time passed.
This patch allows to add "suspend_again" callback at struct
platform_suspend_ops and let the "suspend_again" callback return true if
the system is required to enter suspend again after the current instance
of wakeup. Device-wise suspend_again implemented at dev_pm_ops or
syscore is not done because: a) suspend_again feature is usually under
platform-wise decision and controls the behavior of the whole platform
and b) There are very limited devices related to the usage cases of
suspend_again; chargers and temperature sensors are mentioned so far.
With suspend_again callback registered at struct platform_suspend_ops
suspend_ops in kernel/power/suspend.c with suspend_set_ops by the
platform, the suspend framework tries to enter suspend again by
looping suspend_enter() if suspend_again has returned true and there has
been no errors in the suspending sequence or pending wakeups (by
pm_wakeup_pending).
Tested at Exynos4-NURI.

Instead of having firmware command functions return an error and also
a status, leading to code like:
err = mthca_FW_COMMAND(..., &status);
if (err)
goto out;
if (status) {
err = -E...;
goto out;
}
all over the place, just handle the FW status inside the FW command
handling code (the way mlx4 does it), so we can simply write:
err = mthca_FW_COMMAND(...);
if (err)
goto out;
In addition to simplifying the source code, this also saves a healthy

Support adding probes on offline kernel modules. This enables
perf-probe to trace kernel-module init functions via perf-probe.
If user gives the path of module with -m option, perf-probe
expects the module is offline.
This feature works with --add, --funcs, and --vars.
E.g)
# perf probe -m /lib/modules/`uname -r`/kernel/fs/btrfs/btrfs.ko \
-a "extent_io_init:5 extent_state_cache"
Add new events:
probe:extent_io_init (on extent_io_init:5 with extent_state_cache)
probe:extent_io_init_1 (on extent_io_init:5 with extent_state_cache)
You can now use it on all perf tools, such as:
perf record -e probe:extent_io_init_1 -aR sleep 1

Since die_find/walk* callbacks use DIE_FIND_CB_FOUND for
both of failed and found cases, it should be "END"
instead "FOUND" for avoiding confusion.

Add i2c bindings for the mcp230xx devices. This is quite a lot simpler
than the spi one as there's no funky sub addressing done (one struct
i2c_client per struct gpio_chip).
The mcp23s08_platform_data structure is reused for i2c, even though
only a single mcp23s08_chip_info structure is needed.
To use, simply fill out a platform_data structure and pass it in
i2c_board_info, E.G.:
static const struct mcp23s08_platform_data mcp23017_data = {
.chip[0] = {
.pullups = 0x00ff,
},
.base = 240,
};
static struct i2c_board_info __initdata i2c_devs[] = {
{ I2C_BOARD_INFO("mcp23017", 0x20),
.platform_data = &smartview_mcp23017_data, },
...
};

Change spi member of struct mcp23s08 to be a ops-specific opaque data

No functional change, but is needed to add i2c support.

Since the address of a module-local variable can only be

To support probing module init functions, kprobe-tracer allows
user to define a probe on non-existed function when it is given
with a module name. This also enables user to set a probe on
a function on a specific module, even if a same name (but different)
function is locally defined in another module.
The module name must be in the front of function name and separated
by a ':'. e.g. btrfs:btrfs_init_sysfs

Instead of creating our own kthread (dlm_astd) to deliver
callbacks for all lockspaces, use a per-lockspace workqueue
to deliver the callbacks. This eliminates complications and
slowdowns from many lockspaces sharing the same thread.

Commit 3fe1698b7fe0 ("sched: Deal with non-atomic min_vruntime reads

an infinite while loop in task_waking_fair() under some circumstances
(early boot, lucky timing).
[ This bug was also reported by others that blamed it on the RCU
initialization problems ]
