1429db83e2 driver core: Convert debug functions declared inline __attribute__((format (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;
}
# 628 "include/linux/device.h"
static inline __attribute__((always_inline)) int __attribute__ ((format (printf, 2, 3)))
dev_vdbg(struct device *dev, const char *fmt, ...)
{
 return 0;
}

Removing these unused inlines from sched.i shrinks sched.o

00a41db522 driver core: register_memory/unregister_memory clean ups and bugfix
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().

b54f2863a2 UIO: Implement a UIO interface for the SMX Cryptengine
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.

076c54c5bc Security: Introduce security= boot parameter
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.

d1643d24c6 [NET]: Fix and allocate less memory for ->priv'less netdevices
This patch effectively reverts commit d0498d9ae1
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.

855d854a33 libata: fix boot panic with SATAPI devices on non-SFF HBAs
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.

d45ac4fa8f [SCSI] bsg: takes a ref to struct device in fops->open
bsg_register_queue() takes a ref to struct device that a caller
passes. For example, bsg takes a ref to the sdev_gendev for scsi
devices. However, bsg doesn't inrease the refcount in fops->open. So
while an application opens a bsg device, the scsi device that the bsg
device holds can go away (bsg also takes a ref to a queue, but it
doesn't prevent the device from going away).

With this patch, bsg increases the refcount of struct device in
fops->open and decreases it in fops->release.

2309e9e040 ocfs2/net: Add debug interface to o2net
This patch exposes o2net information via debugfs. The information includes
the list of sockets (sock_containers) as well as the list of outstanding
messages (send_tracking). Useful for o2dlm debugging.

(This patch is derived from an earlier one written by Zach Brown that
exposed the same information via /proc.)

409753bf6d ocfs2/cluster: Get rid of arguments to the timeout routines
We keep seeing bug reports related to NULL pointer derefs in
o2net_set_nn_state(). When I originally wrote up the configurable timeout
patch, I had tried to plan for multiple clusters. This was silly.

The timeout routines all use o2nm_single_cluster so there's no point in
passing an argument at all. This patch removes the arguments and kills those
bugs dead.
