f74c034d52 sh: do not latency trace idle.
Description snipped from Steven Rostedt's PPC patch:

    When idle is called, interrupts are blocked, but the idle
    function will still wake up on an interrupt. The problem is
    that the interrupt disabled latency tracer will take this call
    to idle as a latency.

    This patch disables the latency tracing when going into idle.

5dd614761f sh: Re-add support for best fit ISA tuning if none is available.
This was removed in the libgcc integration, but there are still some
compilers that need this. We also relax the rules on the ISA tuning in
the cases where there are no matches for the CPU tuning and adopt the
-any default, which matches the intent of the isa-y target list. This
compensates for mismatches where binutils supports a wide array of
targets whilst the compiler is much more restricted.

716777db72 sh: P4 ioremap pass-through
This patch adds a pass-through case when ioremapping P4 addresses.

Addresses passed to ioremap() should be physical addresses, so the
best option is usually to convert the virtual address to a physical
address before calling ioremap. This will give you a virtual address
in P2 which matches the physical address and this works well for
most internal hardware blocks on the SuperH architecture.

However, some hardware blocks must be accessed through P4. Converting
the P4 address to a physical and then back to a P2 does not work. One
example of this is the sh7722 TMU block, it must be accessed through P4.

Without this patch P4 addresses will be mapped using PTEs which
requires the page allocator to be up and running.

98a79d6a50 cpumask: centralize cpu_online_map and cpu_possible_map
Impact: cleanup

Each SMP arch defines these themselves.  Move them to a central
location.

Twists:
1) Some archs (m32, parisc, s390) set possible_map to all 1, so we add a
   CONFIG_INIT_ALL_POSSIBLE for this rather than break them.

2) mips and sparc32 '#define cpu_possible_map phys_cpu_present_map'.
   Those archs simply have phys_cpu_present_map replaced everywhere.

3) Alpha defined cpu_possible_map to cpu_present_map; this is tricky
   so I just manipulate them both in sync.

4) IA64, cris and m32r have gratuitous 'extern cpumask_t cpu_possible_map'
   declarations.

 kernel/sched.c:7319: error: non-static initialization of a flexible array member
 kernel/sched.c:7319: error: (near initialization for '(anonymous)')

this happens because .span changed to cpumask_var_t, hence
the static CPU_MASK_NONE initializers in the SD_*_INIT
templates are not type-correct anymore.

Remove them, as they default to empty anyway.

Also remove them from IA64, MIPS and SH.

Under qemu there is a race between the TDxE read-and-clear and the SCxTDR
write. While on hardware it can be gauranteed that the read-and-clear
will happen prior to the character being written out, no such assumption
can be made under emulation. As this path happens with IRQs off and the
hardware itself doesn't care about the ordering, move the SCxTDR write
until after the read-and-clear.

5d52013cbb sh: __copy_user function can corrupt the stack in case of exception
The __copy_user function can corrupt the stack in the case of a
non-trivial length of data, and either of the first two move instructions
cause an exception. This is because the fixup for these two instructions
is mapped to the no_pop case, but these instructions execute after the
stack is pushed.

This change creates an explicit NO_POP exception mapping macro, and uses
it for the two instructions executed in the trivial case where no stack

2cd0ebc83d sh: Fixed the TMU0 reload value on resume
This patch fixes the TMU0 interrupt frequency on suspend/resume.
During the resume the kernel reprograms the TMU0.ClockEvent mode
but if the mode is periodic than the TMU0.TCOR is updated with
a random wrong value without taking care latest valid saved value.

There was no problem with No_HZ system where TMU0.TCOR isn't used.

185aed7557 sh: Provide a sane valid_phys_addr_range() to prevent TLB reset with PMB.
With the PMB enabled, only P1SEG and up are covered by the PMB mappings,
meaning that situations where out-of-bounds physical addresses are read
from will lead to TLB reset after the PMB miss, allowing for use cases
like dd if=/dev/mem to reset the TLB.

Fix this up to make sure the reference is between __MEMORY_START (phys)
and __pa(high_memory). This is coherent across all variants of sh/sh64
with and without MMU, though the PMB bug itself is only applicable to
SH-4A parts.

acca4f4d9b sh: Handle fixmap TLB eviction more coherently.
There was a race in the kmap_coherent() implementation. While we
guarded against preemption, there was nothing preventing eviction of
the pre-faulted fixmap entry from the UTLB. Under certain workloads
this would result in the fixmap entries used for cache colouring being
evicted from the UTLB in the midst of a copy_page().

In addition to pre-faulting, we also make sure to preserve the PTEs
in the kernel page table and introduce a cached PTE for kmap_coherent()
usage. This follows a similar change on MIPS ("[MIPS] Fix aliasing bug
in copy_to_user_page / copy_from_user_page").

b2d86a3fd9 sh: Simplify and lock down the ISA tuning.
The ISA tuning as it is today can not cope with all of the different
variations that are possible, so all we can do is a best attempt based on
the CPU family. The DSP and FPU generation are already at odds with each
other, and the nommu tuning we weren't handling at all.  Additionally,
for platforms that never had an FPU, the -nofpu variant never existed,
meaning that we would lose out on family granular tuning completely in
certain cases.

With tat out of the way, we were also using -up versions, allowing for
later instructions that branched off of a particular subset of the ISA,
but are not actually reflected on the hardware being targetted. This
leads to some confusion, and the possibility of bogus instructions on
older parts. Kill that off and lock it down to the family being built
for specifically.

8a2fd5f3ab sh: Fix FPU tuning on toolchains with mismatched multilib targets.
Presently there is very little standing in the way of using an SH-4
toolchain for building an SH-2 kernel, and vice versa. Binutils itself
has no limitations whatsoever and supports explicit ISA hinting, which
we already use with varying degrees of success today.

This leaves GCC as the odd one out, due to a rather dubious policy
decision by the GCC folks to not include all of the CPU family variants
in the default list of multilib targets in GCC4. Despite best efforts to
the contrary, libgcc itself already contains awareness of the various CPU
types and remains generally usable, allowing it to safely be referenced
even on a mismatched target (and indeed, explicit ISA tuning by binutils
keeps us honest in terms of ensuring that we do not link incompatible
objects in).

In order to support this, a couple of changes had to be made. Firstly,
the introduction of MAYBE_DECLARE_EXPORT(), which provides a __weak
extern reference for libgcc resident routines when finer-grained
-m<cpu-family> based tuning is not supported by the toolchain. This
fixes up the __sdivsi3_i4i and __udivsi3_i4i references when dealing
with SH-2 kernels linked with an SH-4 libgcc. Secondly, in case where we
are unable to find a suitable match for CPU family tuning but still
have a toolchain that defaults to FP instruction generation, a suitable
nofpu target must be selected. This is accomplished by selecting the
first nofpu multilib target supported by the toolchain, which is
also necessary for selecting the proper libgcc to link against.

57cac4d188 kdump: make elfcorehdr_addr independent of CONFIG_PROC_VMCORE
o elfcorehdr_addr is used by not only the code under CONFIG_PROC_VMCORE
  but also by the code which is not inside CONFIG_PROC_VMCORE.  For
  example, is_kdump_kernel() is used by powerpc code to determine if
  kernel is booting after a panic then use previous kernel's TCE table.
  So even if CONFIG_PROC_VMCORE is not set in second kernel, one should be
  able to correctly determine that we are booting after a panic and setup
  calgary iommu accordingly.

o So remove the assumption that elfcorehdr_addr is under
  CONFIG_PROC_VMCORE.

o Move definition of elfcorehdr_addr to arch dependent crash files.
  (Unfortunately crash dump does not have an arch independent file
  otherwise that would have been the best place).

o kexec.c is not the right place as one can Have CRASH_DUMP enabled in
  second kernel without KEXEC being enabled.

o I don't see sh setup code parsing the command line for
  elfcorehdr_addr.  I am wondering how does vmcore interface work on sh.
  Anyway, I am atleast defining elfcoredhr_addr so that compilation is not
  broken on sh.

dc52ddc0e6 container freezer: implement freezer cgroup subsystem
This patch implements a new freezer subsystem in the control groups
framework.  It provides a way to stop and resume execution of all tasks in
a cgroup by writing in the cgroup filesystem.

The freezer subsystem in the container filesystem defines a file named
freezer.state.  Writing "FROZEN" to the state file will freeze all tasks
in the cgroup.  Subsequently writing "RUNNING" will unfreeze the tasks in
the cgroup.  Reading will return the current state.

* Examples of usage :

   # mkdir /containers/freezer
   # mount -t cgroup -ofreezer freezer  /containers
   # mkdir /containers/0
   # echo $some_pid > /containers/0/tasks

to get status of the freezer subsystem :

   # cat /containers/0/freezer.state
   RUNNING

to freeze all tasks in the container :

   # echo FROZEN > /containers/0/freezer.state
   # cat /containers/0/freezer.state
   FREEZING
   # cat /containers/0/freezer.state
   FROZEN

to unfreeze all tasks in the container :

   # echo RUNNING > /containers/0/freezer.state
   # cat /containers/0/freezer.state
   RUNNING

This is the basic mechanism which should do the right thing for user space
task in a simple scenario.

It's important to note that freezing can be incomplete.  In that case we
return EBUSY.  This means that some tasks in the cgroup are busy doing
something that prevents us from completely freezing the cgroup at this
time.  After EBUSY, the cgroup will remain partially frozen -- reflected
by freezer.state reporting "FREEZING" when read.  The state will remain
"FREEZING" until one of these things happens:

	1) Userspace cancels the freezing operation by writing "RUNNING" to
		the freezer.state file
	2) Userspace retries the freezing operation by writing "FROZEN" to
		the freezer.state file (writing "FREEZING" is not legal
		and returns EIO)
	3) The tasks that blocked the cgroup from entering the "FROZEN"
		state disappear from the cgroup's set of tasks.

14866543ad sh: More I/O routine overhauling.
This tidies up a lot of the PIO/MMIO split. No in-tree platforms were
making use of the MMIO overloading through the machvec (nor have any of
them been in some time), so we just kill all of that off. The ISA I/O
routine wrapping remains unaffected, which remains the only special
casing outside of the iomap API that boards need to think about.

3d58695edb sh: Trivial trace_mark() instrumentation for core events.
This implements a few trace points across events that are deemed
interesting. This implements a number of trace points:

	- The page fault handler / TLB miss
	- IPC calls
	- Kernel thread creation

The original LTTng patch had the slow-path instrumented, which
fails to account for the vast majority of events. In general
placing this in the fast-path is not a huge performance hit, as
we don't take page faults for kernel addresses.

The other bits of interest are some of the other trap handlers, as
well as the syscall entry/exit (which is better off being handled
through the tracehook API). Most of the other trap handlers are corner
cases where alternate means of notification exist, so there is little
value in placing extra trace points in these locations.

Based on top of the points provided both by the LTTng instrumentation
patch as well as the patch shipping in the ST-Linux tree, albeit in a
stripped down form.
