From: Andrew Morton <akpm@linux-foundation.org>

gcc-3.4.4 on powerpc:

drivers/net/via-velocity.c:443: error: chip_info_table causes a section type conflict

on this one I had to remove the __devinitdata too.  Don't know why.

f4e64333f8 isdn: fix section mismatch warning for ISACVer
Fix following warnings:
WARNING: drivers/isdn/hisax/built-in.o(.text+0x19723): Section mismatch in reference from the function ISACVersion() to the variable .devinit.data:ISACVer
WARNING: drivers/isdn/hisax/built-in.o(.text+0x2005b): Section mismatch in reference from the function setup_avm_a1_pcmcia() to the function .devinit.text:setup_isac()

ISACVer were only used from function annotated __devinit
so add same annotation to ISACVer.
One af the fererencing functions missed __devinit so add it
and kill an additional warning.

checkcard() are the only user of hisax_cs_setup_card().
And checkcard is only used during init or when hot plugging
ISDN devices. So annotate hisax_cs_setup_card() with __devinit.
checkcard() is used by exported functions so it cannot be
annotated __devinit. Annotate it with __ref so modpost
ignore references to _devinit section.

initisar(), initisac() and clear_pending_isac_ints()
were all used via a cardmsg fnction - which may be called
ouside __devinit context.
So remove the bogus __devinit annotation of the
above three functions to fix the warnings.

7740ac6a7c isdn: fix section mismatch warning in hfc_sx.c
Fix the following warning:
WARNING: drivers/isdn/hisax/built-in.o(.text+0x35818): Section mismatch in reference from the function hfcsx_card_msg() to the function .devinit.text:inithfcsx()

hfcsx_card_msg() may be called outside __devinit context.
Following the program logic is looks like the CARD_INIT branch
will only be taken under __devinit context but to be consistent
remove the __devinit annotation of inithfcsx() so we
do not mix non-__devinit and __devinit code.

b1d0e4f535 mm: special mapping nopage
Convert special mapping install from nopage to fault.

Because the "vm_file" is NULL for the special mapping, the generic VM
code has messed up "vm_pgoff" thinking that it's an anonymous mapping
and the offset does't matter.  For that reason, we need to undo the
vm_pgoff offset that got added into vmf->pgoff.

[ We _really_ should clean that up - either by making this whole special
  mapping code just use a real file entry rather than that ugly array of
  "struct page" pointers, or by just making the VM code realize that
  even if vm_file is NULL it may not be a regular anonymous mmap.

4600ecfcf3 lib/scatterlist.o needed by a module only - link it in unconditionally
lib/scatterlist.c is needed by drivers/media/video/videobuf-dma-sg.c, and
we would like to be able to use the latter without PCI too, for example, on
PXA270 ARM CPU.  It is then possible to create a configuration with
CONFIG_BLOCK=n, where only module code will need scatterlist.c.  Therefore
it must be in obj-y.

6784fd5931 Fix FRV cmpxchg_local
Fix the FRV cmpxchg_local by breaking the following header dependency loop :

linux/kernel.h -> linux/bitops.h -> asm-frv/bitops.h -> asm-frv/atomic.h
  -> asm-frv/system.h ->
  asm-generic/cmpxchg_local.h -> typecheck() defined in linux/kernel.h

and

linux/kernel.h -> linux/bitops.h -> asm-frv/bitops.h -> asm-frv/atomic.h ->
  asm-generic/cmpxchg_local.h -> typecheck() defined in linux/kernel.h

In order to fix this :
- Move the atomic_test_and_ *_mask inlines from asm-frv/atomic.h (why are they
  there at all anyway ? They are not touching atomic_t variables!) to
  asm-frv/bitops.h.

Also fix a build issue with cmpxchg : it does not cast to (unsigned long *)
like other architectures, to deal with it in the cmpxchg_local macro.

FRV builds fine with this patch.

Thanks to Adrian Bunk <bunk@kernel.org> for spotting this bug.

7143740d26 IPoIB: Add send gather support
This patch acts as a preparation for using checksum offload for IB
devices capable of inserting/verifying checksum in IP packets.  The
patch does not actaully turn on NETIF_F_SG - we defer that to the
patches adding checksum offload capabilities.

We only add support for send gathers for datagram mode, since existing
HW does not support checksum offload on connected QPs.

All current InfiniBand devices can handle all DMA addresses, and it's
hard to imagine anyone would be silly enough to build a new device
that couldn't.  Therefore, enable the NETIF_F_HIGHDMA feature for IPoIB.

This has no effect for no, but is needed when we enable gather/scatter

ea54b10c77 IB/mlx4: Use multiple WQ blocks to post smaller send WQEs
ConnectX HCA supports shrinking WQEs, so that a single work request
can be made of multiple units of wqe_shift.  This way, WRs can differ
in size, and do not have to be a power of 2 in size, saving memory and
speeding up send WR posting.  Unfortunately, if we do this then the
wqe_index field in CQEs can't be used to look up the WR ID anymore, so
our implementation does this only if selective signaling is off.

Further, on 32-bit platforms, we can't use vmap() to make the QP
buffer virtually contigious. Thus we have to use constant-sized WRs to
make sure a WR is always fully within a single page-sized chunk.

Finally, we use WRs with the NOP opcode to avoid wrapping around the
queue buffer in the middle of posting a WR, and we set the
NoErrorCompletion bit to avoid getting completions with error for NOP
WRs.  However, NEC is only supported starting with firmware 2.2.232,
so we use constant-sized WRs for older firmware.  And, since MLX QPs
only support SEND, we use constant-sized WRs in this case.

When stamping during NOP posting, do stamping following setting of the
NOP WQE valid bit.

785285fc8b [IA64] Fix large MCA bootmem allocation
The MCA code allocates bootmem memory for NR_CPUS, regardless
of how many cpus the system actually has.  This change allocates
memory only for cpus that actually exist.

On my test system with NR_CPUS = 1024, reserved memory was reduced by 130944k.

Before: Memory: 27886976k/28111168k available (8282k code, 242304k reserved, 5928k data, 1792k init)
After:  Memory: 28017920k/28111168k available (8282k code, 111360k reserved, 5928k data, 1792k init)

3b2ce0b178 [IA64] Synchronize kernel RSE to user-space and back
This is base kernel patch for ptrace RSE bug. It's basically a backport
from the utrace RSE patch I sent out several weeks ago. please review.

when a thread is stopped (ptraced), debugger might change thread's user
stack (change memory directly), and we must avoid the RSE stored in
kernel to override user stack (user space's RSE is newer than kernel's
in the case). To workaround the issue, we copy kernel RSE to user RSE
before the task is stopped, so user RSE has updated data.  we then copy
user RSE to kernel after the task is resummed from traced stop and
kernel will use the newer RSE to return to user.
