83b964bbf8 mm: arch: make in_gate_area take an mm_struct instead of a task_struct
Morally, the question of whether an address lies in a gate vma should be asked
with respect to an mm, not a particular task.  Moreover, dropping the dependency
on task_struct will help make existing and future operations on mm's more
flexible and convenient.

31db58b3ab mm: arch: make get_gate_vma take an mm_struct instead of a task_struct
Morally, the presence of a gate vma is more an attribute of a particular mm than
a particular task.  Moreover, dropping the dependency on task_struct will help
make both existing and future operations on mm's more flexible and convenient.

fb7f045ace sh: Fix ptrace hw_breakpoint handling
Since commit 34d0b5af50 it is no longer
possible to debug an application using singlestep. The old commit
converted singlestep handling via ptrace to hw_breakpoints. The
hw_breakpoint is disabled when an event is triggered and not re-enabled
again. This patch re-enables the existing hw_breakpoint before the
existing breakpoint is reused.

c49b6ecf08 sh: Fix ptrace fpu state initialisation
Commit 0ea820cf introduced the PTRACE_GETFPREGS/SETFPREGS cmds,
but gdb-server still accesses the FPU state using the
PTRACE_PEEKUSR/POKEUSR commands. In this case, xstate was not
initialised.

37a9d912b2 futex: Sanitize cmpxchg_futex_value_locked API
The cmpxchg_futex_value_locked API was funny in that it returned either
the original, user-exposed futex value OR an error code such as -EFAULT.
This was confusing at best, and could be a source of livelocks in places
that retry the cmpxchg_futex_value_locked after trying to fix the issue
by running fault_in_user_writeable().
    
This change makes the cmpxchg_futex_value_locked API more similar to the
get_futex_value_locked one, returning an error code and updating the
original value through a reference argument.

before we reuse it from/for something else or shut it down.

Without this ioctl it would have to temporarily become the owner of

a25bbe1222 sh: Flush executable pages in copy_user_highpage
This resolves a problem seen when using the Android dynamic linker.
Sometimes the dynamic linker would seg-fault at start up and this
was eventually traced to the handling of a COW fault for a page which
was being modified by the linker. If there was no cache aliasing between
the kernel and the user page, the page was not flushed, leaving the
newly copied data in the D-cache. However when executing instructions
from that page, the I-cache is filled directly from external memory,
rather than the D-cache, and causing garbage to be executed.

f17c13ca52 ASoC: sh: fsi: modify selection method of I2S/PCM/SPDIF format
Current format selection of FSI-codecs depended on platform information for FSI,
and chip default settings for codecs. It is not understandable/formal method.
This patch modify FSI and FSI-codecs to use snd_soc_dai_set_fmt.

But FSI can use I2S/PCM and SPDIF format today.
It can be selected to I2S/PCM by snd_soc_dai_set_fmt, but can not select SPDIF.
So, this patch change FSI platform information to have DAI/SPDIF mode.

If platform selects DAI mode (default),
FSI-codecs can select I2S/PCM by snd_soc_dai_set_fmt,
and if it is SPDIF mode, FSI become SPDIF format.

and performance degradation.

This patch adds @cacheline parameter to PERCPU() and PERCPU_VADDR()

size and use it to align percpu subsections.

6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

Occasionally the system gets into a state where the CMOS clock has gotten
slightly ahead of current time and the periodic update of RTC fails.  The
message is a nuisance and repeats spamming the log.

  See: http://www.ntp.org/ntpfaq/NTP-s-trbl-spec.htm#Q-LINUX-SET-RTC-MMSS

Rather than just removing the message, make it show only once and reduce
severity since it indicates a normal and non urgent condition.

Add probe support for the sh7372 SH4AL-DSP core.

The most common use case for this is when the system
boots from the ARM core in the sh7372 and uses the
SH core for application offload as a slave CPU.

May also be used to boot the sh7372 from the SH core.

efb3e34b61 sh: Fix up legacy PTEA space attribute mapping.
When p3_ioremap() was converted to ioremap_prot() there was some breakage
introduced where the 29-bit segmentation logic would trap the area range
and return an identity mapping without having allowed the area
specification to force mapping through page tables. This wires up a PCC
mask for pgprot verification to work out whether to short-circuit the
identity mapping on legacy parts, restoring the previous behaviour.

1dee92bba3 sh: Tidy up SH-4A unaligned load support.
The current implementation was rather tied to the packed_struct.h
definitions, which immediately began to clash when the packed_struct.h
types changed and drivers began to include packed_struct.h directly.

In order to support this sort of use it's necessary to get out of the way
with regards to namespace collisions, and at the same time we can also
kill off some duplicate code now that the unaligned headers are a bit
more broken out.

As the only caller of sh_mmcif_boot_do_read() is
sh_mmcif_boot_slurp() the configuration portion of
sh_mmcif_boot_slurp() can be merged into sh_mmcif_boot_do_read().

Once this is done sh_mmcif_boot_slurp() is only a call
to sh_mmcif_boot_do_read() with platform specific information -
the offset that images are stored on MMC. So make the
sh_mmcif_boot_do_read() call directly from platform code
and remove sh_mmcif_boot_slurp() altogether.

This follows the ARM change c01778001a
("ARM: 6379/1: Assume new page cache pages have dirty D-cache") for the
same rationale:

    There are places in Linux where writes to newly allocated page
    cache pages happen without a subsequent call to flush_dcache_page()
    (several PIO drivers including USB HCD). This patch changes the
    meaning of PG_arch_1 to be PG_dcache_clean and always flush the
    D-cache for a newly mapped page in update_mmu_cache().

This addresses issues seen with executing binaries from MMC, in
addition to some of the other HCDs that don't explicitly do cache
management for their pipe-in buffers.

004417a6d4 perf, arch: Cleanup perf-pmu init vs lockup-detector
The perf hardware pmu got initialized at various points in the boot,
some before early_initcall() some after (notably arch_initcall).

The problem is that the NMI lockup detector is ran from early_initcall()
and expects the hardware pmu to be present.

Sanitize this by moving all architecture hardware pmu implementations to
initialize at early_initcall() and move the lockup detector to an explicit
initcall right after that.

d53e4307c2 sh: Use GCC __builtin_prefetch() to implement prefetch().
GCC's __builtin_prefetch() was introduced a long time ago, all
supported GCC versions have it. So this patch is to use it for
implementing the prefetch on SH2A and SH4.

The current  prefetch implementation is almost equivalent with
__builtin_prefetch.
The third parameter in the __builtin_prefetch is the locality
that it's not supported on SH architectures.  It has been set
to three and it should be verified if it's suitable for SH2A
as well. I didn't test on this architecture.

The builtin usage should be more efficient that an __asm__
because less barriers, and because the compiler doesn't see the
inst as a "black box" allowing better code generation.

This has been already done on other architectures (see the commit:
0453fb3c52).

Many thanks to Christian Bruel <christain.bruel@st.com> for his
support on evaluate the impact of the gcc built-in on SH4 arch.

This takes a bit of a sledgehammer to the machvec I/O routines. The
iomem case requires no special casing and so can just be dropped
outright. This only leaves the ioport casing for PCI and SuperIO
mangling. With the SuperIO case going through the standard ioport
mapping, it's possible to replace everything with generic routines.

MRSHPC is wholly unused here, no need to trap it specially. If support is
added in the future it can be taken care of via platform data like on the
others.

The only reason this board needs to do PIO trapping is for ethernet,
which happens to follow the same scheme as its bigger brother the
edosk7760. With ethernet properly supported through the platform device,
we can kill off the left over PIO abortion.

The microdev only has to contend with silly PIO mangling on anything
within the SuperIO range. As each of the SuperIO modules is already
speciail cased, we just shift that logic over to the ioport map.

With microdev PCI never being merged (and being fudamentally broken in
hardware), and the ethernet chip only doing 16-bit accesses already,
there's no need to maintain any of the extra special casing. Kill it all
off.

op_name_from_perf_id() currently returns a local variable, which isn't
terribly productive. As we only handle a single PMU case for now, simply
allocate and free the string from the arch init/exit context and have
op_name_from_perf_id() hand back the cached string.

This also takes UTS_MACHINE in to account, given that we build for
