f7eee89b2a [ARM] 4192/1: AT91: Support for AT91SAM9XE processors.
Add support for the Atmel AT91SAM9XE range of processors.  These are
basically AT91SAM9260's with different amounts of internal SRAM and
Flash.

We make use of the existing AT91SAM9260 support, but just perform
run-time detection of the size of the internal SRAM.

Original patch from Nicolas Ferre.

93a3ddc201 [ARM] 4151/1: AT91 / AVR32: Move at91_pdc.h to linux/atmel_pdc.h
The Atmel AT91 and AVR32 processor architectures share many of the same
peripherals.  The PDC (Peripheral Data Controller) registers are also
implemented within in a number of the on-chip peripherals (eg, USART,
MMC, SPI, SSC, etc).

In a attempt not to duplicate the register definitions in each
peripheral, or in each architecture, the at91_pdc.h header in
asm-arm/arch-at91 and asm-avr32/arch-at32ap has been replaced with
linux/atmel_pdc.h.

The definitions have also been renamed from AT91_PDC_* to ATMEL_PDC_*,
and the drivers updated accordingly.

d0760b3bc8 [ARM] 4143/1: AT91: Prepare for AT91SAM9263 support
The Atmel AT91SAM9263 processor includes many more integrated
peripherals than Atmel's previous ARM9-based AT91 processors, so this
has necessitated a few changes to the core AT91 support.

These changes are:
      * The system peripheral I/O region we remap has increased from
        0xFFFA0000..0xFFFFFFFF to 0xFFF78000..0xFFFFFFFF.
      * The increased I/O region forces changes to entry-macro.S and
        debug-macro.S due to ARM's limited immediate offset addressing
        modes.
      * Maximum number of GPIO banks increases to 5.
      * 2 MMC controllers so the board-setup code needs to specify which
        controller it wishes to use when calling at91_add_device_mmc().

9d0412680e [ARM] 4124/1: Rename mach-at91rm9200 and arch-at91rm9200 directories
Now that Linux includes support for the Atmel AT91SAM9260 and
AT91SAM9261 processors in addition to the original Atmel AT91RM9200
(with support for more AT91 processors pending), the "mach-at91rm9200"
and "arch-at91rm9200" directories should be renamed to indicate their
more generic nature.

The following git commands should be run BEFORE applying this patch:
  git-mv arch/arm/mach-at91rm9200 arch/arm/mach-at91
  git-mv include/asm-arm/arch-at91rm9200 include/asm-arm/arch-at91

a93d48cc60 [ARM] 4119/1: AT91: Fix build of AT91SAM9260
Fix build failure of AT91SAM9260.

The AT91RM9200 ethernet driver (at91_ether.c) stores platform data in a
"struct at91_eth_data" structure, but the AT91SAM9260 (and AT91SAM9263)
ethernet driver (macb.c) [developed on the AVR32 architecture] expects a
"struct eth_platform_data".

Since the platform data of the two drivers is very similar, we continue
to use the "struct at91_eth_data" for all AT91 processors but add a
    #define eth_platform_data      at91_eth_data
in board.h to keep the MACB driver happy.

7ef416c4b8 [ARM] Improve csum_fold, cleanup csum_tcpudp_magic()
csum_fold doesn't need two assembly instructions to perform its task,
it can simply add the high and low parts together by rotating by 16
bits, and the carry into the upper-16 bits will automatically happen.

Also, since csum_tcpudp_magic() is just csum_tcpudp_nofold + csum_fold,
use those two functions to achieve this.  Also note that there is a
csum_fold() at the end of ip_fast_csum() as well, so use the real
csum_fold() there as well.

Boot tested on Versatile.

0f2452855d [PATCH] namespaces: fix task exit disaster
This is based on a patch by Eric W.  Biederman, who pointed out that pid
namespaces are still fake, and we only have one ever active.

So for the time being, we can modify any code which could access
tsk->nsproxy->pid_ns during task exit to just use &init_pid_ns instead,
and move the exit_task_namespaces call in do_exit() back above
exit_notify(), so that an exiting nfs server has a valid tsk->sighand to
work with.

Long term, pulling pid_ns out of nsproxy might be the cleanest solution.

701dfbc1cb [PATCH] mm: mremap correct rmap accounting
Nick Piggin points out that page accounting on MIPS multiple ZERO_PAGEs
is not maintained by its move_pte, and could lead to freeing a ZERO_PAGE.

Instead of complicating that move_pte, just forget the minor optimization
when mremapping, and change the one thing which needed it for correctness
- filemap_xip use ZERO_PAGE(0) throughout instead of according to address.

7a238fcba0 [PATCH] namespaces: fix exit race by splitting exit
Fix exit race by splitting the nsproxy putting into two pieces.  First
piece reduces the nsproxy refcount.  If we dropped the last reference, then
it puts the mnt_ns, and returns the nsproxy as a hint to the caller.  Else
it returns NULL.  The second piece of exiting task namespaces sets
tsk->nsproxy to NULL, and drops the references to other namespaces and
frees the nsproxy only if an nsproxy was passed in.

A little awkward and should probably be reworked, but hopefully it fixes
the NFS oops.

76398f9667 HID: fix pb_fnmode and move it to generic HID
The apple powerbook people are used to switch the pb_fnmode
setting at runtime through writing to sysfs, altering the
module parameter value. This was broken for them in 2.6.20-rc1
when generic HID layer was introduced, as the pb_fnmode flag
was made per-hiddevice, instead of global variable.

This patch moves the pb_fnmode module parameter from usbhid module
to hid module, but apart from that retains backward compatibility
with respect to changing the mode through sysfs.

7d2aae1e88 [PATCH] ALSA: Fix sysfs breakage
The recent change for a new sysfs tree with card* object breaks the
/sys/class/sound tree if CONFIG_SYSFS_DEPRECATED is enabled.
The device in each entry doesn't point the correct device object:

  /sys/class/sound
  ...
  |-- pcmC0D0c
  |   |-- dev
  |   |-- device -> ../../../class/sound/card0
  |   |-- pcm_class
  |   |-- power
  |   |   `-- wakeup
  |   |-- subsystem -> ../../../class/sound
  |   `-- uevent

Also, this change breaks some drivers (like sound/arm/*) referring
card->dev directly to obtain the device object for memory handling.

This patch reverts the semantics of card->dev to the former version,
which points to a real device object.  The card* object is stored in a
new card->card_dev field, instead.  The device parent is chosen either
card->dev or card->card_dev according to CONFIG_SYSFS_DEPRECATED to
keep the tree compatibility.
Also, card* isn't created if CONFIG_SYSFS_DEPRECATED is enabled.  The
reason of card* object is a root of all beloing devices, and it makes
little sense if each sound device points to the real device object
directly.

8cdf92a98f Fix Maple PATA IRQ assignment.
On the Maple board, the AMD8111 IDE is in legacy mode... except that it
appears on IRQ 20 instead of IRQ 15. For drivers/ide this was handled by
the architecture's "pci_get_legacy_ide_irq()" function, but in libata we
just hard-code the numbers 14 and 15.

This patch provides asm-powerpc/libata-portmap.h which maps the IRQ as
appropriate, having added a pci_dev argument to the
ATA_{PRIM,SECOND}ARY_IRQ macros.

There's probably a better way to do this -- especially if we observe
that the _only_ case in which this seemingly-generic
"pci_get_legacy_ide_irq()" function returns anything other than 14 and
15 for primary and secondary respectively is the case of the AMD8111 on
the Maple board -- couldn't we handle that with a special case in the
pata_amd driver, or perhaps with a PCI quirk for Maple to switch it into
native mode during early boot and assign resources properly?

2a2275d630 [PATCH] md: fix potential memalloc deadlock in md
If a GFP_KERNEL allocation is attempted in md while the mddev_lock is held,
it is possible for a deadlock to eventuate.

This happens if the array was marked 'clean', and the memalloc triggers a
write-out to the md device.

For the writeout to succeed, the array must be marked 'dirty', and that
requires getting the mddev_lock.

So, before attempting a GFP_KERNEL allocation while holding the lock, make
sure the array is marked 'dirty' (unless it is currently read-only).

a0ad13ef64 [PATCH] knfsd: Fix type mismatch with filldir_t used by nfsd
nfsd defines a type 'encode_dent_fn' which is much like 'filldir_t' except
that the first pointer is 'struct readdir_cd *' rather than 'void *'.  It
then casts encode_dent_fn points to 'filldir_t' as needed.  This hides any
other type mismatches between the two such as the fact that the 'ino' arg
recently changed from ino_t to u64.

So: get rid of 'encode_dent_fn', get rid of the cast of the function type,
change the first arg of various functions from 'struct readdir_cd *' to
'void *', and live with the fact that we have a little less type checking
on the calling of these functions now.  Less internal (to nfsd) checking
offset by more external checking, which is more important.

Thanks to Gabriel Paubert <paubert@iram.es> for discovering this and
providing an initial patch.

250f391518 [PATCH] knfsd: fix an NFSD bug with full sized, non-page-aligned reads
NFSd assumes that largest number of pages that will be needed for a
request+response is 2+N where N pages is the size of the largest permitted
read/write request.  The '2' are 1 for the non-data part of the request, and 1
for the non-data part of the reply.

However, when a read request is not page-aligned, and we choose to use
->sendfile to send it directly from the page cache, we may need N+1 pages to
hold the whole reply.  This can overflow and array and cause an Oops.

This patch increases size of the array for holding pages by one and makes sure
that entry is NULL when it is not in use.

f47aef55d9 [PATCH] i386 vDSO: use VM_ALWAYSDUMP
This patch fixes core dumps to include the vDSO vma, which is left out now.
It removes the special-case core writing macros, which were not doing the
right thing for the vDSO vma anyway.  Instead, it uses VM_ALWAYSDUMP in the
vma; there is no need for the fixmap page to be installed.  It handles the
CONFIG_COMPAT_VDSO case by making elf_core_dump use the fake vma from
get_gate_vma after real vmas in the same way the /proc/PID/maps code does.

This changes core dumps so they no longer include the non-PT_LOAD phdrs from
the vDSO.  I made the change to add them in the first place, but in turned out
that nothing ever wanted them there since the advent of NT_AUXV.  It's cleaner
to leave them out, and just let the phdrs inside the vDSO image speak for
themselves.

a1f3bb9ae4 [PATCH] Fix CONFIG_COMPAT_VDSO
I wouldn't mind if CONFIG_COMPAT_VDSO went away entirely.  But if it's there,
it should work properly.  Currently it's quite haphazard: both real vma and
fixmap are mapped, both are put in the two different AT_* slots, sysenter
returns to the vma address rather than the fixmap address, and core dumps yet
are another story.

This patch makes CONFIG_COMPAT_VDSO disable the real vma and use the fixmap
area consistently.  This makes it actually compatible with what the old vdso
implementation did.
