This patch contains the following possible cleanups:
- cx18-i2c.c should #include "cx18-i2c.h" for getting the prototypes of
it's global functions
- make the following needlessly global functions static:
- cx18-fileops.c:cx18_claim_stream()
- cx18-fileops.c:cx18_release_stream()
- cx18-queue.c:cx18_queue_move()
- remove the following unused functions:
- cx18-driver.c:cx18_waitq()
- cx18-queue.c:cx18_buf_copy_from_user()

Since:
1) FW_LOADER is defined as:
config FW_LOADER
tristate "Userspace firmware loading support"
depends on HOTPLUG
2) several V4L/DVB driver just selects it;
3) select is not smart enough to auto-select HOTPLUG, if select FW_LOADER.
So, All drivers that select FW_LOADER should also depend on HOTPLUG.
An easier solution (for the end-user perspective) would be to "select HOTPLUG".
However, live is not simple. This would cause recursive dependency issues like
this one:
drivers/usb/Kconfig:62:error: found recursive dependency: USB -> USB_OHCI_HCD

drivers/built-in.o: In function `cinergyt2_probe':
cinergyT2.c:(.text+0xb6117): undefined reference to `input_allocate_device'
cinergyT2.c:(.text+0xb6230): undefined reference to `input_register_device'

with the following config:
http://redhat.com/~mingo/misc/config-Sun_May__4_22_06_54_CEST_2008.bad
The reason for the bug is that the cinergyT2 driver depends on
CONFIG_INPUT functionality, but if INPUT is modular it's still possible
to build CONFIG_DVB_CINERGYT2=y - which leads to missing symbols.
The solution is to make DVB_CINERGYT2 dependent on INPUT.

This change addresses kernel bug #10459: In kernel 2.6.25 the
budget_av driver polls for an CI slot in 100ms intervals (because no
interrupt solution for budget_av cards is feasible due to HW reasons).
If no CI/CAM is connected to the DVB card, polling times out only after 250ms.
This periodic polling leads to high CPU load.
The change increases the polling interval for empty slots from 100ms to 5s.
Intervals for remaining slot states (invalid, in progress, ready) are unchanged,
as they are either temporary conditions or no timeout should occur.

In case of inode preallocation, the number of blocks to allocate depends
on the file size and it is calculated in ext4_mb_normalize_request().
Each group in the filesystem is then checked to find one that can be
used for allocation; this is done in ext4_mb_good_group().
When a file bigger than 4MB is created, the requested number of blocks
to preallocate, calculated by ext4_mb_normalize_request is 4096.
However for a filesystem with 1KB block size, the maximum size of the
block buddies used by the multiblock allocator is 2048, so none of
groups in the filesystem satisfies the search criteria in
ext4_mb_good_group(). Scanning all the filesystem groups impacts
performance.
This was demonstrated by using a freshly created, 70GB, 1k block
filesystem, with caches dropped write before the test via
/proc/sys/vm/drop_caches, and with the filesystem mounted with
nodelalloc and nodealloc,nomballoc. The time to write an 8 megabyte
file using "dd if=/dev/zero of=/mnt/test/fo bs=8k count=1k conv=fsync"
took 35.5091 seconds (236kB/s) with nodellaloc, and 0.233754 seconds
(35.9 MB/s) with the nodelloc,nomballoc options. With a 1TB partition,
it took several minutes to write 8MB!
This patch modifies the algorithm in ext4_mb_normalize_group_request to
calculate the number of blocks to allocate by taking into account the
maximum size of free blocks chunks handled by the multiblock allocator.
It has also been tested for filesystems with 2KB and 4KB block sizes to
ensure that those cases don't regress.

We should not allow user to change quota mount options when quota is
just suspended. It would make mount options and internal quota state
inconsistent. Also we should not allow user to change quota format when
quota is turned on. On the other hand we can just silently ignore when
some option is set to the value it already has (mount does this on
remount).

Andrew Morton <akpm@linux-foundation.org> pointed out that bitops

doing bitops on struct ipath_devdata.ipath_sdma_status, which is u64.
Change this member to unsigned long to avoid tons of warnings when x86
fixes the bitops to take unsigned long * instead of void *.
Also, change the IPATH_SDMA_RUNNING and IPATH_SDMA_SHUTDOWN bit
numbers to 30 and 31 (instead of 62 and 63) so that we're not setting
another booby trap for someone who tries to make ipath work on a

The official reason is "with the presence of pid namespaces in the
kernel using pid_t-s inside one is no longer safe."
But the reason I fix this right now is the following:
About a month ago (when 2.6.25 was not yet released) there still was a
one last caller of a to-be-deprecated-soon function find_pid() - the
kill_proc() function, which in turn was only used by nfs callback
code.
During the last merge window, this last caller was finally eliminated
by some NFS patch(es) and I was about to finally kill this kill_proc()
and find_pid(), but found, that I was late and the kill_proc is now
called from the ipath driver since commit 58411d1c ("IB/ipath: Head of
Line blocking vs forward progress of user apps").
So here's a patch that fixes this code to use struct pid * and (!)
the kill_pid routine.

Fix some bugs with the max_aggr module parameter added with LRO support:
- The module parameter value ignored and not actually used to set
lro_mgr.max_aggr.
- MODULE_PARM_DESC had a typo "_mro_" instead of "_lro_" so it didn't
end up describing the actual module parameter.
- The nes_lro_max_aggr variable was declared as unsigned, but the
module_param line said "int" instead of "uint" for the type.
- The default value for the parameter was stuck in the permissions
field of module_param, which led to nonsensical permissions for the
file under /sys/module/iw_nes/param.
- The parameter was used in only one file but defined in another, which
led to the variable being global for no good reason. Move everything
related to the parameter to the file nes_hw.c where it is actually
used.
