2d4dc890b5 block: add helpers to run flush_dcache_page() against a bio and a request's pages
Mtdblock driver doesn't call flush_dcache_page for pages in request.  So,
this causes problems on architectures where the icache doesn't fill from
the dcache or with dcache aliases.  The patch fixes this.

The ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE symbol was introduced to avoid
pointless empty cache-thrashing loops on architectures for which
flush_dcache_page() is a no-op.  Every architecture was provided with this
flush pages on architectires where ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE is
equal 1 or do nothing otherwise.

See "fix mtd_blkdevs problem with caches on some architectures" discussion
on LKML for more information.

865bddfbf7 Blackfin: fix suspend/resume failure with some on-chip ROMs
Some Blackfin on-chip ROMs utilize some MDMA channels during the suspend
and resume process, but don't clean up after themselves.  So manually
clear all DMA channels when resuming since no DMA could have been running
at this point in time.  Now Linux should be able to work regardless of any
laziness on the part of the on-chip ROM or boot loader.

a2e2725541 net: Introduce recvmmsg socket syscall
Meaning receive multiple messages, reducing the number of syscalls and
net stack entry/exit operations.

Next patches will introduce mechanisms where protocols that want to
optimize this operation will provide an unlocked_recvmsg operation.

This takes into account comments made by:

. Paul Moore: sock_recvmsg is called only for the first datagram,
  sock_recvmsg_nosec is used for the rest.

. Caitlin Bestler: recvmmsg now has a struct timespec timeout, that
  works in the same fashion as the ppoll one.

  If the underlying protocol returns a datagram with MSG_OOB set, this
  will make recvmmsg return right away with as many datagrams (+ the OOB
  one) it has received so far.

. Rémi Denis-Courmont & Steven Whitehouse: If we receive N < vlen
  datagrams and then recvmsg returns an error, recvmmsg will return
  the successfully received datagrams, store the error and return it
  in the next call.

This paves the way for a subsequent optimization, sk_prot->unlocked_recvmsg,
where we will be able to acquire the lock only at batch start and end, not at
every underlying recvmsg call.

59bd00c850 Blackfin: fix framebuffer mmap bug for nommu
The patch added a special get_unmapped_area for framebuffer which
was hooked to the file ops in drivers/video/fbmem.c.

This is needed since v2.6.29-rc1 where nommu vma management was
updated, and mmap of framebuffer caused kernel BUG panic. You may turn
on "Debug the global anon/private NOMMU mapping region tree" config to
such message.

As Documentation/nommu-mmap.txt said,
"To provide shareable character device support, a driver must provide
a file->f_op->get_unmapped_area() operation. The mmap() routines will
call this to get a proposed address for the mapping."

With this change, user space should call mmap for framebuffer using
shared map. Or it can try shared map first, then private map if
failed. This shared map usage is now consistent between mmu and nommu.

The sys_ file may not be a good place for this patch. But there is a
similar one for sparc. I tested a similar patch on nios2nommu, though
I don't have a blackfin board to test.

48dee09325 Blackfin: cplbinfo: drop d_path() hacks
The cplbinfo was using d_path() to figure out which cpu/cplb was being
parsed.  As Al pointed out, this isn't exactly reliable as it assumes the
static VFS path to be unchanged, and it's just poor form.  So use the
proc_create_data() to properly (and internally) pass the exact cpu/cplb
requested to the parser function.

It also removes:
 - verbose GPL text(refer to the top level ./COPYING file)
 - file names (you are looking at the file)
 - bug url (it's in the ./MAINTAINERS file)
 - "or later" on GPL-2, when we did not have that right

It also allows some Blackfin-specific assembly files to be under a BSD
like license (for people to use them outside of Linux).

I've taken my best swing at converting this, but I'm not 100% confident

wasn't able to check if it compiled. Any assistance from arch

cdd6c482c9 perf: Do the big rename: Performance Counters -> Performance Events
Bye-bye Performance Counters, welcome Performance Events!

In the past few months the perfcounters subsystem has grown out its
initial role of counting hardware events, and has become (and is
becoming) a much broader generic event enumeration, reporting, logging,
monitoring, analysis facility.

Naming its core object 'perf_counter' and naming the subsystem
'perfcounters' has become more and more of a misnomer. With pending
code like hw-breakpoints support the 'counter' name is less and
less appropriate.

All in one, we've decided to rename the subsystem to 'performance
events' and to propagate this rename through all fields, variables
and API names. (in an ABI compatible fashion)

The word 'event' is also a bit shorter than 'counter' - which makes
it slightly more convenient to write/handle as well.

Thanks goes to Stephane Eranian who first observed this misnomer and
suggested a rename.

User-space tooling and ABI compatibility is not affected - this patch
should be function-invariant. (Also, defconfigs were not touched to
keep the size down.)

This patch has been generated via the following script:

  FILES=$(find * -type f | grep -vE 'oprofile|[^K]config')

  sed -i \
    -e 's/PERF_EVENT_/PERF_RECORD_/g' \
    -e 's/PERF_COUNTER/PERF_EVENT/g' \
    -e 's/perf_counter/perf_event/g' \
    -e 's/nb_counters/nb_events/g' \
    -e 's/swcounter/swevent/g' \
    -e 's/tpcounter_event/tp_event/g' \
    $FILES

  for N in $(find . -name perf_counter.[ch]); do
    M=$(echo $N | sed 's/perf_counter/perf_event/g')
    mv $N $M
  done

  FILES=$(find . -name perf_event.*)

  sed -i \
    -e 's/COUNTER_MASK/REG_MASK/g' \
    -e 's/COUNTER/EVENT/g' \
    -e 's/\<event\>/event_id/g' \
    -e 's/counter/event/g' \
    -e 's/Counter/Event/g' \
    $FILES

... to keep it as correct as possible. This script can also be
used by anyone who has pending perfcounters patches - it converts
a Linux kernel tree over to the new naming. We tried to time this
change to the point in time where the amount of pending patches
is the smallest: the end of the merge window.

Namespace clashes were fixed up in a preparatory patch - and some
stylistic fallout will be fixed up in a subsequent patch.

( NOTE: 'counters' are still the proper terminology when we deal
  with hardware registers - and these sed scripts are a bit
  over-eager in renaming them. I've undone some of that, but
  in case there's something left where 'counter' would be
  better than 'event' we can undo that on an individual basis
  instead of touching an otherwise nicely automated patch. )

caa27b66bd kbuild: use INSTALLKERNEL to select customized installkernel script
Replace the use of CROSS_COMPILE to select a customized
installkernel script with the possibility to set INSTALLKERNEL
to select a custom installkernel script when running make:

    make INSTALLKERNEL=arm-installkernel install

With this patch we are now more consistent across
different architectures - they did not all support use
of CROSS_COMPILE.

The use of CROSS_COMPILE was a hack as this really belongs
to gcc/binutils and the installkernel script does not change
just because we change toolchain.

The use of CROSS_COMPILE caused troubles with an upcoming patch
that saves CROSS_COMPILE when a kernel is built - it would no
longer be installable.
[Thanks to Peter Z. for this hint]

This patch undos what Ian did in commit:

  0f8e2d62fa
  ("use ${CROSS_COMPILE}installkernel in arch/*/boot/install.sh")

The patch has been lightly tested on x86 only - but all changes
looks obvious.

5bf9cbef99 Blackfin: update ftrace for latest toolchain
The mcount support that was finally added to the Blackfin gcc port isn't
exactly the same as what ftrace was developed against.  Now that the final
gcc version is in place, update the ftrace code to match.

While updating this, fix the swapped arguments to the tracer (signature is
(ip, parent_ip) while we were passing (parent_ip, ip)).

3b67d91b3e Blackfin: fix elf_fpregset_t definition
The elf_fpregset_t type relied on an empty struct in the asm/user.h, but
the transition to asm-generic/user.h dropped that empty struct.  Rather
than restore this useless struct, define the only user (elf_fpregset_t)
as an empty struct itself.  This fixes building when ELF dump support is
enabled.

ea426e6c62 Blackfin: unify cache init functions
The CPLB implementations (mpu/nompu) had exact copies of the cacheinit
code.  Even the i/d cache functions are largely the same.  So unify them
both in the common kernel cache code.

e78feaaeeb Blackfin: swap clocksource ratings for gptimer/cycles
The cycles clocksource is a higher resolution than the gptimer one, so
make sure the ratings field reflects this.

3289651a97 Blackfin: update ftrace_push_return_trace() breakage
Commit 71e308a239 updated ftrace_push_return_trace() prototype but didn't
update the Blackfin ftrace code, so things broke.  Since we don't support
the new stuff yet, call it with stub values.

The cm-bf537u module, while similar to the cm-bf537e, is different enough
to warrant its own resources.  It has a USB controller but no PHY.

88c28b2df9 Blackfin: increase default async timings for parallel flashes
The default async timings are a little too fast for the parallel flash
that is attached by default to the async banks.  So slow things down a bit
so accessing the hardware is stable.
