2b79adcca1 [JFFS2] Use f->target instead of f->dents for symlink target
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.

7015faa7df [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.  ;)

c51e3a417b powerpc: Fix vmlinux.lds.S for 32-bit
We can't currently use asm-ppc/page.h in vmlinux.lds.S, so until
we have a merged page.h, define PAGE_SIZE and KERNELBASE locally.
Also gets rid of some dynamic executable cruft that we had for
32-bit.  With -Ttext=$(KERNELBASE) this didn't cause any problem,
but when we changed to putting . = KERNELBASE in the vmlinux.lds.S
this cruft caused the text to get linked at 0xa0 instead of
0xc0000000.  Oops.

d530838bfa NFSv4: Fix problem with OPEN_DOWNGRADE

 share_deny bits specified for some subset of the OPENs in effect for
 current openowner on the current file.

 Setattr is currently violating the NFSv4 rules for OPEN_DOWNGRADE in that
 it may cause a downgrade from OPEN4_SHARE_ACCESS_BOTH to
 OPEN4_SHARE_ACCESS_WRITE despite the fact that there exists no open file
 with O_WRONLY access mode.

 nfs_find_open_context().
