This is the latest/Updated OS_MCA handler which try to do recovery
from multibit-ECC/poisoned memory-read error on user-land.
(Thank you very much for comments, Keith and Grant!)

I'd still appreciate it if anyone having good test environment
could apply my patch and could report how it works.
(especially reports on non-Tiger/non-Intel platform are welcome.)

If we read and write the PROM chips at the same time, as might happen at boot
when salinfo extracts MCA records and a user is checking the PROM revision
in /proc/sgi_prominfo, an MCA might occur, since the PROM chips can't be
accessed that way.  This patch fixes the problem for systems with new PROMs
(>= 3.50) by using the SAL to do PROM reads.

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.
