device_is_registered() can use the kobject value for this, so it will
now work with devices that are associated with only a class, not a bus
and a driver.

This patch (as1058) improves the wakeup macros in include/linux/pm.h.
All but the trivial ones are converted to inline routines, which
requires moving them to a separate header file since they depend on
the definition of struct device.

The various wakeup flags and their accessor macros in struct
dev_pm_info should be available whenever CONFIG_PM is enabled, not
just when CONFIG_PM_SLEEP is on. Otherwise remote wakeup won't always
be configurable for runtime power management. This patch (as1056b)
fixes the oversight.
David Brownell adds:
More accurately, fixes the "regression" ... as noted sometime
last summer, after 296699de6bdc717189a331ab6bbe90e05c94db06
introduced CONFIG_SUSPEND. But that didn't make the regression
list for that kernel, ergo the delay in fixing it.

This patch (as1059) fixes a mistake in the way the serial core

Include dpm_sysfs_add() into device_pm_add(), in analogy with
device_pm_remove(), and modify device_add() to call the latter after
bus_add_device(), to avoid situations in which the PM core may
attempt to suspend a device the registration of which has not been
successful.

Modify the PM core to protect its data structures, specifically the
dpm_active list, from being corrupted if a child of the currently
suspending device is registered concurrently with its ->suspend()
callback. In that case, since the new device (the child) is added
to dpm_active after its parent, the PM core will attempt to
suspend it after the parent, which is wrong.
Introduce a new member of struct dev_pm_info, called 'sleeping',
and use it to check if the parent of the device being added to
dpm_active has been suspended, in which case the device registration
fails. Also, use 'sleeping' for checking if the ordering of devices
on dpm_active is correct.
Introduce variable 'all_sleeping' that will be set to 'true' once all
devices have been suspended and make new device registrations fail
until 'all_sleeping' is reset to 'false', in order to avoid having
unsuspended devices around while the system is going into a sleep state.
Remove pm_sleep_rwsem which is not necessary any more.
Special thanks to Alan Stern for discussions and suggestions that
lead to the creation of this patch.

I've just found how easy it is to accidentally register a sysdev_driver for
two different classes. When this happens, bad things happen as the
sysdev_driver structure keeps has the list entry for the driver
registration.
The following patch makes a WARN_ON() if this happens, although I think
BUG_ON or returning -EAGAIN could also be valid responses to this.

Fix following warning:
WARNING: vmlinux.o(.text+0x64609c): Section mismatch in reference from the function store_online() to the function .cpuinit.text:cpu_up()
store_online() is defined inside a HOTPLUG_CPU block so references are OK.
Ignore references by annotating store_online() with __ref.
Note: This is needed because cpu_up() most likely should not have been
__cpuinit but all the hotplug cpu code misuses the __cpuinit annotation.

The current PNP combined card + devices module aliase can
never ever match anything, because these values are not available
all at the same time to request a module.
Instead of adding the combined alias, we add the device id's
all as individual aliases. Device id's are exported by the PNP
bus and can now properly used to request the loading of a
matching module.
The module snd-sbawe currently exports aliases, which can never
match anything:
alias: pnp:cCTLXXXXdCTL0045dCTL0022*
alias: pnp:cCTLXXXXdCTL0044dCTL0023*
alias: pnp:cCTLXXXXdCTL0042dCTL0022*

alias: pnp:cCTL0039dCTL0031dCTL0021*
alias: pnp:cCTL0035dCTL0031dCTL0021*
With this patch it exports only the device id's, as properly
matchable aliases:
alias: pnp:dCTL0070*
alias: pnp:dCTL0045*
alias: pnp:dCTL0023*
alias: pnp:dCTL0044*

alias: pnp:dCTL0042*
alias: pnp:dCTL0041*
alias: pnp:dCTL0021*
alias: pnp:dCTL0031*
Now, the exported value of the PNP bus can be used to autoload
a matching module:
$ modprobe --first-time -n -v pnp:dCTL0045

(printf,x,y) to statement expression macros
When DEBUG is not defined, pr_debug and dev_dbg and some
other local debugging functions are specified as:
"inline __attribute__((format (printf, x, y)))"
This is done to validate printk arguments when not debugging.
Converting these functions to macros or statement expressions
"do { if (0) printk(fmt, ##arg); } while (0)"
or
"({ if (0) printk(fmt, ##arg); 0; })
makes at least gcc 4.2.2 produce smaller objects.
This has the additional benefit of allowing the optimizer to
avoid calling functions like print_mac that might have been
arguments to the printk.
defconfig x86 current:
$ size vmlinux
text data bss dec hex filename
4716770 474560 618496 5809826 58a6a2 vmlinux
all converted: (More patches follow)
$ size vmlinux
text data bss dec hex filename
4716642 474560 618496 5809698 58a622 vmlinux
Even kernel/sched.o, which doesn't even use these
functions, becomes smaller.
It appears that merely having an indirect include
of <linux/device.h> can cause bigger objects.
$ size sched.inline.o sched.if0.o
text data bss dec hex filename
31385 2854 328 34567 8707 sched.inline.o
31366 2854 328 34548 86f4 sched.if0.o
The current preprocessed only kernel/sched.i file contains:
# 612 "include/linux/device.h"
static inline __attribute__((always_inline)) int __attribute__ ((format (printf, 2, 3)))
dev_dbg(struct device *dev, const char *fmt, ...)
{
return 0;

register_memory()/unregister_memory() never gets called with
"root". unregister_memory() is accessing kobject_name of
the object just freed up. Since no one uses the code,
lets take the code out. And also, make register_memory() static.
Another bug fix - before calling unregister_memory()
remove_memory_block() gets a ref on kobject. unregister_memory()
need to drop that ref before calling sysdev_unregister().

This patch implements a UIO interface for the SMX Cryptengine.
The Cryptengine found on the Nias Digital SMX board is best suited
for a UIO interface. It is not wired in to the cryptographic API
as the engine handles it's own keys, algorithms, everything. All
that we know about is that if there's room in the buffer, you can
write data to it and when there's data ready, you read it out again.
There isn't necessarily even any direct correlation between data
going in and data coming out again, the engine may consume or
generate data all on its own.
This driver is for proprietary hardware but we're always told to
submit the drivers anyway; here you are. :-)
This is version 4 of this patch and addresses all issues raised by
Hans-Jürgen Koch and Paul Mundt in their reviews. Slightly altered
is Paul's suggestion to use DRV_NAME and DRV_VERSION as the UIO
version and name. While at the moment they are the same, there
is no reason for them to stay that way. Nevertheless we now at
least provide a MODULE_VERSION macro to keep modinfo happy.

Add the security= boot parameter. This is done to avoid LSM
registration clashes in case of more than one bult-in module.
User can choose a security module to enable at boot. If no
security= boot parameter is specified, only the first LSM
asking for registration will be loaded. An invalid security
module name will be treated as if no module has been chosen.
LSM modules must check now if they are allowed to register
by calling security_module_enable(ops) first. Modify SELinux
and SMACK to do so.
Do not let SMACK register smackfs if it was not chosen on
boot. Smackfs assumes that smack hooks are registered and
the initial task security setup (swapper->security) is done.

This patch effectively reverts commit d0498d9ae1a5cebac363e38907266d5cd2eedf89
aka "[NET]: Do not allocate unneeded memory for dev->priv alignment."
It was found to be buggy because of final unconditional += NETDEV_ALIGN_CONST
removal.
For example, for sizeof(struct net_device) being 2048 bytes, "alloc_size"
was also 2048 bytes, but allocator with debugging options turned on started
giving out !32-byte aligned memory resulting in redzones overwrites.
Patch does small optimization in ->priv'less case: bumping size to next
32-byte boundary was always done to ensure ->priv will also be aligned.
But, no ->priv, no need to do that.

The kernel now panics reliably on boot if you have a SATAPI device
connected.
The problem was introduced by the libata merge trying to pull out all
the SFF code into a separate module. Unfortunately, if you're a satapi
device you usually need to call atapi_request_sense, which has a bare
invocation of a SFF callback which is NULL on non-SFF HBAs. Fix this by
making the call conditional.
