Various Orion cleanups:
- Unify GPL license banner format across all files.
- Unify naming of .h double inclusion guard preprocessor macros.
- Unify spelling of "PCIe" (variants seen: PCIE, PCIe, PCI-EX.)
- Various typo fixes.
- Remove __init attributes from prototypes declared in headers.
- Remove trailing comments from #endif statements.
- Mark a couple of locally-used-only structs static.

Move the Orion register accessor macros out of orion.h, to prevent
them from ending up in the decompressor image (Orion uncompress.h
includes orion.h.) Move them into io.h, which seems a better place
for this kind of stuff.

Instead of forcing all device bus window setup through one function
with some enum as the first argument, create separate window setup
functions for each of the four possible targets, and do the demux
internally. This allows getting rid of the window identifier enum
and the big switch statement in orion_setup_cpu_win().

This fixes the builtin RTL8139 NIC on the Medion MD9580-F laptop. The
BIOS reports the interrupt routing incorrectly. I recently added a
quirk to work around this, and this patch fixes a typo in the quirk.
We pad every ACPI pathname component to four characters, so ".ISA." will
never match anything. We need ".ISA_." instead.
Thank you Johann-Nikolaus Andreae <johann-nikolaus.andreae@nacs.de>

If an I2C interrupt happens between disabling interface clock
and functional clock, the interrupt handler will produce an
external abort on non-linefetch error when trying to access
driver registers while interface clock is disabled.
This patch fixes the problem by saving and disabling i2c-omap
interrupt before turning off the clocks. Also disable functional
clock before the interface clock as suggested by Paul Walmsley.
Patch also renames enable/disable_clocks functions to unidle/idle
functions. Note that the driver is currently not taking advantage
of the idle interrupts. To use the idle interrupts, driver would
have to enable interface clock based on the idle interrupt
and dev->idle flag.
This patch has been tested in linux-omap tree with various omaps.

While backporting 72dc67a69690288538142df73a7e3ac66fea68dc, a gfn_to_page()
call was duplicated instead of moved (due to an unrelated patch not being
present in mainline). This caused a page reference leak, resulting in a
fairly massive memory leak.
Fix by removing the extraneous gfn_to_page() call.

The vmx hardware state restore restores the tss selector and base address, but
not its length. Usually, this does not matter since most of the tss contents
is within the default length of 0x67. However, if a process is using ioperm()
to grant itself I/O port permissions, an additional bitmap within the tss,
but outside the default length is consulted. The effect is that the process
will receive a SIGSEGV instead of transparently accessing the port.
Fix by restoring the tss length. Note that i386 had this working already.
Closes bugzilla 10246.

Somebody had put struct nameidata in stack frame of link_path_walk().
Unfortunately, there are certain realities to deal with:
* It's in the middle of recursion. Depth is equal to the nesting
depth of symlinks, i.e. up to 8.
* struct namiedata is, even if one discards the intent junk,
at least 12 pointers + 5 ints.
* moreover, adding a stack frame is not free in that situation.
* there are fs methods called on top of that, and they also have
stack footprint.
* kernel stack is not infinite.
The thing is, even if one chooses to deal with -ESTALE that way (and it's
one hell of an overkill), the only thing that needs to be preserved is
vfsmount + dentry, not the entire struct nameidata.

Make sure no-one calls dentry_open with a NULL vfsmount argument and crap
out with a stacktrace otherwise. A NULL file->f_vfsmnt has always been
problematic, but with the per-mount r/o tracking we can't accept anymore
at all.

After several posts and bug reports regarding interaction with the NULL
nameidata, here's a patch to clean up the mess with struct file in the
reiserfs xattr code.
As observed in several of the posts, there's really no need for struct file
to exist in the xattr code. It was really only passed around due to the
f_op->readdir() and a_ops->{prepare,commit}_write prototypes requiring it.
reiserfs_prepare_write() and reiserfs_commit_write() don't actually use the
struct file passed to it, and the xattr code uses a private version of
reiserfs_readdir() to enumerate the xattr directories.

* hppfs_iget() and its users are racy; there's no need to pollute icache
anyway, new_inode() works fine and is safe, unlike the current kludges
(these relied on overwriting ->i_ino before another iget_locked() gets
to that one - and did it after unlocking).
* merge hppfs_iget()/init_inode()/hppfs_read_inode(), while we are
at it.
* to pass proper vfsmount to dentry_open() store the reference
in hppfs superblock.

Here's patch for hppfs that uses vfs_kern_mount to make sure it always has a
procfs instance and passed the vfsmount on through the inode private data.
Also fixes a procfs file_system_type leak for every attempted hppfs mount.
[ jdike - gave this file a style workover, plus deleted hppfs_dentry_ops ]

vfs_kern_mount() requires having a reference to fs type, which
makes it impossible for module to create procfs, etc. private
mount. Open-coding is not an option, since e.g. put_filesystem()
is _not_ exported, and for a good reason.

The VIA VT6212 defaults to only waiting 1us between passes over EHCI's
async ring, which hammers PCI badly ... and by preventing other devices
from accessing the bus, causes problems like drops in IDE throughput,
a problem that's been bugging users of those chips for several years.
A (partial) datasheet for this chip eventually turned up, letting us
see how to make it use a VIA-specific register to switch over to the
the normal 10us value instead, as suggested by the EHCI specification
Solution noted by Lev A. Melnikovsky.
It's not clear whether this register exists on other VIA chips; we
know that it's ineffective on the vt8235. So this patch only applies
to chips that seem to be incarnations of the (discrete) vt6212.

while I was adding autosuspend to that driver I noticed a few issues.
You were having DMAed buffers as a part of a structure.
This will fail on platforms that are not DMA-coherent (arm, sparc, ppc, ...)
Please test this patch to fix it.

Motorola ROKR Z6 cellphone has bugs in its USB, so it is impossible to use
it as mass storage. Patch describes new "unusual" USB device for it with
FIX_INQUIRY and FIX_CAPACITY flags and new BULK_IGNORE_TAG flag.
Last flag relaxes check for equality of bcs->Tag and us->tag in
usb_stor_Bulk_transport routine.
