Make the "addr" arg to test_bit "const" to prevent flood of compile
warnings in networking code.

This adds a cache of lastest accessed cluster to inode for sequential
access.

The following is 500M file of FAT-to-FAT copy test, this may be a most
different case in usual operations, because maximum readahead window
flush the all caches.

512 bytes blocksize, 4096 bytes cluster size.

This shifts the data position caches from module to per-superblock, and
cleanups.

This removes the obsolete Documentation/filesystems/fat_cvf.txt.

This fixes the return value of ioctl() for enables using the same way as
readdir().

put/get_user() return code check patch from John R R Leavitt

This adds large partition (> 128GB) support to FAT.

This silences at least one compile-time warning... :-)

This is needed to match the output of the C compiler.

This header ends up getting included by uClibc (though nothing in it is
used), so this protection is necessary to avoid problems with kernel-only
typedefs.

This is to define `struct file'; apparently some include-file change
removed a previous implicit include.

These registers are now saved in a difference place, but the old code
was inadvertently left in.

	fs/inode.c assumes that any ->delete_inode() will call clear_inode().
procfs instance doesn't.  It had passed unpunished for a while; cdev changes
combined with ALSA creating character devices in procfs made it fatal.

	Patch follows.  It had fixed ALSA-triggered memory corruption here -
what happens in vanilla 2.5.70 is that clear_inode() is not called when
procfs character device inodes are freed.  That leaves a freed inode on
a cyclic list, with obvious unpleasantness following when we try to traverse
it (e.g. when unregistering a device).

This allows drivers to resize their tag depth at run-time.

Argh.  Missing initialization in char_dev.c - it's definitely
responsible for crap on unload.  Load side appears to be something else,
though...

agp_init() just printk's a banner. This is unnecessary at this early stage.

Alan (or someone else) added a buggy BUG_ON() in ide-cd. We can address >
32-bit just fine with 2kb block size. People are hitting this, just got
one more report today...
