It fixes an oops that results when a lobe fault is detected.  The oops
occurs because a lobe fault triggers an interrupt which is handled
in the current version of the driver by effectively shutting down the
card, and freeing its requisite irq.  The former is fine, the latter
is not, as its illegal to free an irq from within an interrupt context.

I've fixed this bug by removing the call to free_irq from the interrupt
handler (specifically the chunk around line 964 fixes that).  While I
was in there I noticed that there were several other conditions in
the interrupt handler that contained the same condition, so I made
the same fix there.  I re-added.

I also modified the contents of olympic_freemem (the chunk around line
898 to correct a misuse of a pointer after it requisite memory has
been free in the case the the adapter is re-initalized after a fault
to prevent that oops.  And then I clean up the interrupt handler to
simply use olympic_freemem from the close routine since the ring buffer
doesn't need to be freed until the driver is closed.

In addition to these changes I added a call to olympic init in
olympic_open and reset the spinlock so the adapter can be reset and
rejoin the ring without needing to rmmod/insmod the module.  Lastly I
cleaned up the wait queue code so that the close routine didn't have
to wait 60 seconds to close the adapter if a fatal fault has closed
the adapter.

Bartlomiej Zolnierkiewicz wanted to remove the "cbio" structure
from struct request.  Unfortunately, MMC was using the same
"workaround" as IDE to walk the BIO list.  With this change, we
stop using "cbio" and instead use proper scatter-gather lists.

This patch adds a 10 ms delay in the power up loop. Some cards fail
to power up in time without it.

Pierre Ossman reported a problem where his cards do not correctly
initialise with the current MMC implementation.  However, if we
tell the card to go back to the idle state between probing the
supply voltage and telling the card about the chosen voltage, his
cards work - and we don't seem to upset existing cards.

This allows users to provide a fixed major number - early 2.4 MMC
drivers used block device major 60, which is "local/experimental
use"

Use msleep_interruptible() instead of schedule_timeout() to
guarantee the task delays as expected.

It's a rather bad idea to have psa-regs.h included all the time.
It's rather large and likely to create namespace clashes, as well
as slowing down the build unnecessarily.

Better include it explicitly where it is actually needed.

Let's move GPIO setup into the board specific hw init functions.

The PXA2xx often has many different GPIOs that can be used for
a given alternate function and the good one to use is hardware
dependent.  For example, Lubbock and Mainstone are not using all
the same GPIOs for PCMCIA signals.

A disconnected dentry can hold an inode active after the last link has
been removed.  The file will not then be truncated and removed until
memory pressure flushes the disconnected dentry from the dcache.

This problem can be resolved by making sure that an inode never has
both a connected and a disconnected dentry.

This is already the case for directories (as they must only have one
dentry), but it is not the case for non-directories.

This addresses it by:
 - changes d_alloc_anon to make sure that a new disconnected dentry is
   only allocated if there is currently no (hashed) dentry for the
   inode. (Previously this would noramlly be true, but a race was
   possible).
 - changes d_splice_alias to re-use a disconnected dentry on
   non-directories as well as directories.
 - splits most of d_find_alias out into a separate function to make
   the above easier.

Problem originally reported by Nikita Danilov.

Acked by Al Viro ("It looks sane"), and Jakob Oestergaard reports this
fixes his problems. Further pushed by Christoph Hellwig.

The current code allocating the DART has a couple of bugs, first

(oops), and then it tries to access the device-tree using the

Looks like we never needed them, since that bug has been there forever,
I didn't get the right base for the IO cycles on the G5 host bridge
in the first place (I probably misinterpreted some OF forth code or
something like that).

No problems reported other than Linus typo in an unbuildable driver from
the last one.

This one adds tty_ldisc_flush and also makes tty_wakeup do the queue
wake as discussed with Paul.  I've then propagated these functions
through all the drivers.  This means most drivers don't know about the
ldisc locking and instead call generic functions that look after it. 
The result is the removal of a lot of duplicate code both for ldisc
referencing and historical code for handling tty ldisc wakeup semantics.

A nice side effect is that by adding versions of the two helpers we can
switch most of the drivers over before changing the core tty code if
preferred.
