[MTD] NAND sharpsl.c: Add support for akita and borzoi models
The Sharp Zaurus akita and borzoi models are large page flash devices.
This patch adds support for them to the sharpsl MTD NAND driver but
keeps the oob layout and bad block positions compatible with the Sharp
Zaurus 2.4 kernel and ROM bootloader.

[JFFS2] Add erase block summary support (mount time improvement)
The goal of summary is to speed up the mount time. Erase block summary (EBS)
stores summary information at the end of every (closed) erase block. It is
no longer necessary to scan all nodes separetly (and read all pages of them)
just read this "small" summary, where every information is stored which is
needed at mount time.
This summary information is stored in a JFFS2_FEATURE_RWCOMPAT_DELETE. During
the mount process if there is no summary info the orignal scan process will
be executed. EBS works with NAND and NOR flashes, too.
There is a user space tool called sumtool to generate this summary
information for a JFFS2 image.

When JFFS22 is unable to read the root inode, the bad root inode object is not

JFFS2 uses f->dents to store the pointer to the symlink target string (in case
the inode is symlink). This is somewhat ugly to use the same field for
different reasons. Introduce distinct field f->target for this purpose.
Note, f->fragtree, f->dents, f->target may probably be put in a union.

[PATCH] nvidiafb: Geforce 7800 series support added
This adds support for the Nvidia Geforce 7800 series of cards to the
nvidiafb framebuffer driver. All it does is add the PCI device id for
the 7800, 7800 GTX, 7800 GO, and 7800 GTX GO cards to the module device
table for the nvidiafb.ko driver, so that nvidiafb.ko will actually work
on these cards.
I also added the relevant PCI device ids to linux/pci_ids.h
I tested it on my 7800 GTX here and it works like a charm. I now can
get framebuffer support on this card! Woo hoo!! Nothing like 200x75 text
mode to make your eyes BLEED. ;)

[ARM] 3097/1: change library link ordering
Patch from Nicolas Pitre
We have an optimized sha1 routine (arch/arm/lib/sha1.S) meant to
override the generic one in lib/sha1.c.
Unfortunately lib/lib.a is listed _before_ arch/arm/lib/lib.a in the
link argument list and therefore the architecture specific lib functions
are not picked up before the generic versions.
This patch is a quick fix to change that ordering for ARM. Here's what
the kbuild maintainer had to say about it (was also CC'd on lkml):
