as sysfs callbacks can assume it is present and it can race the later

So, create two new functions, deviec_create_vargs() and

device_create_drvdata() will go away in 2.6.27 as the drvdata field will
just be moved to the device_create() call as it should be.

Since 2.6.25 the HID_QUIRK_APPLE_HAS_FN quirk is enabled even for
non-laptop Apple keyboards of the Aluminium series. The USB version of
these don't need Numlock emulation, like the laptop (and Aluminium
Wireless) do, as they have a proper keypad.
This patch splits the Numlock emulation for Apple keyboards in a
different quirk flag, so that it can be enabled for all the keyboards
but the Aluminium USB ones.
If the Numlock emulation is enabled for Aluminium USB keyboards, the
JKL and UIO keys become the numeric pad, and the rest of the keyboard
is disabled, included the key used to disable Numlock.
Additionally, these keyboard should not have a Numlock at all, as the
Numlock key is instead replaced by the 'Clear' key as usual for Apple
USB keyboards.

An NFS_WRITE requires a set of RDMA_READ requests to fetch the write
data from the client. There are two principal pieces of data that
need to be tracked: the list of pages that comprise the completed RPC
and the SGE of dma mapped pages to refer to this list of pages. Previously
this whole bit was managed as a linked list of contexts with the
context containing the page list buried in this list. This patch
simplifies this processing by not keeping a linked list, but rather only
a pionter from the last submitted RDMA_READ's context to the context
that maps the set of pages that describe the RPC. This significantly
simplifies this code path. SGE contexts are cleaned up inline in the DTO
path instead of at read completion time.

Current module loader lookups ".data.percpu" ELF section to perform
per_cpu relocation. But DEFINE_PER_CPU_SHARED_ALIGNED() uses another
section (".data.percpu.shared_aligned"), currently only handled in
vmlinux.lds, not by module loader.
To correct this problem, instead of adding logic into module loader, or
using at build time a module.lds file for all arches to group
".data.percpu.shared_aligned" into ".data.percpu", just use ".data.percpu"
for modules.
Alignment requirements are correctly handled by ld and module loader.

match_strcpy() is a somewhat creepy function: the caller needs to make sure
that the destination buffer is big enough, and when he screws up or
forgets, match_strcpy() happily overruns the buffer.
There's exactly one customer: v9fs_parse_options(). I believe it currently
can't overflow its buffer, but that's not exactly obvious.
The source string is a substing of the mount options. The kernel silently
truncates those to PAGE_SIZE bytes, including the terminating zero. See
compat_sys_mount() and do_mount().
The destination buffer is obtained from __getname(), which allocates from
name_cachep, which is initialized by vfs_caches_init() for size PATH_MAX.
We're safe as long as PATH_MAX <= PAGE_SIZE. PATH_MAX is 4096. As far as
I know, the smallest PAGE_SIZE is also 4096.
Here's a patch that makes the code a bit more obviously correct. It
doesn't depend on PATH_MAX <= PAGE_SIZE.

Prior to 2.6.26 fuse only supported single page write requests. In theory all
fuse filesystem should be able support bigger than 4k writes, as there's
nothing in the API to prevent it. Unfortunately there's a known case in
NTFS-3G where big writes cause filesystem corruption. There could also be
other filesystems, where the lack of testing with big write requests would
result in bugs.
To prevent such problems on a kernel upgrade, disable big writes by default,
but let filesystems set a flag to turn it on.

Because it's not correct with a non-preemptable BKL and just causes
PREEMPT kernels to have longer latencies than non-PREEMPT ones (which is
obviously not the point of it at all).
Of course, that config option actually got removed as an option earlier,
so for now this basically disables it entirely, but if BKL preemption is
ever resurrected it will be a meaningful optimization. And in the
meantime, it at least documents the intent of the code, while not doing
the wrong thing.

We should not go through the task pointer to get at the thread info,
since it's usually cheaper to just access the thread info directly.
So don't make the code look up 'current', when we can just use the
thread info accessor functions directly. This generally avoids one
level of indirection and tends to work better together with code that
also looks at other thread flags (eg preempt_count).
