b7ec479553 [ARM] 3115/1: small optimizations to exception vector entry code
Patch from Nicolas Pitre

Since we know the value of cpsr on entry, we can replace the bic+orr with
a single eor.  Also remove a possible result delay (at least on XScale).

84613387cb [ARM] 3089/1: ixp4xx AHB/PCI endianness fix
Patch from Alessandro Zummo

  This patch fixes AHB/PCI endianness problems when the
 processor is in little-endian mode.

 The patch configures the CSR register closely following the directives
 in [1], paragraph 4.1, page 19.

 According to the considerations in [1], page 11, while the AHB bus
 supports both endian modes, on the IXP4XX it always uses big-endian.

 The PCI bus is connected to the South AHB. A wrong setting in the CSR
 register will thus cause a malfunctional PCI bus.

 A schematic diagram of the bus interconnections on the IXP4XX
 can be found in [1], page 18.

 The patch has been verified to work on the NSLU2 in
 both LE and BE modes.

 The author is Peter Korsgaard.

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
RFC 3530 states that for OPEN_DOWNGRADE "The share_access and share_deny
 bits specified must be exactly equal to the union of the share_access and
 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.

 Fix the problem by replacing nfs4_find_state() with a modified version of
 nfs_find_open_context().

30c2f90b68 [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):

Patch from Dave Jiang

This provides support for IXP2xxx error interrupt handling. Previously there was a patch to remove this (although the original stuff was broken). Well, now the error bits are needed again. These are used extensively by the micro-engine drivers according to Deepak and also we will need it for the new EDAC code that Alan Cox is trying to push into the main kernel.

30415f6a63 powerpc: Fix random memory corruption in merged elf.h
The merged verison of ELF_CORE_COPY_REGS is basically the PPC64 version, with
a memset that came from PPC and a few types abstracted out into #defines. But
it's not _quite_ right.

The first problem is we calculate the number of registers with:
        nregs = sizeof(struct pt_regs) / sizeof(ELF_GREG_TYPE)

For a 32-bit process on a 64-bit kernel that's bogus because the registers are
64 bits, but ELF_GREG_TYPE is u32, so nregs == 88 which is wrong.

The other problem is the memset, which assumes a struct pt_regs is smaller
than a struct elf_regs. For a 32-bit process on a 64-bit kernel that's false.

The fix is to calculate the number of regs using sizeof(unsigned long), which
should always be right, and just memset the whole damn thing _before_ copying
the registers in.
