SH-5 doesn't support any elaborate ISA inheritance schemes (-dsp, -up,

This code has been dead for many years. The last update it received
was in 2003 in order to update it for the driver model changes, though
it had already been in disarray and unused before that point. The only
boards that ever used this chip have not had users in many years either,
so it is finally safe to just kill it off and move on with life.

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.

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.

Rather than varying this on a subtype level, we use the counter type as a
generic identifier. This simplifies logic in the userspace tools where no
fundamental difference exists across the various subtypes.

Commit 3f5a54e371ca20b119b73704f6c01b71295c1714 ("ftrace: dump out ftrace
buffers to console on panic") added an ftrace buffer dumper that hooks
in to the die notifier chain and dumps out data in the oops path.
Unfortunately SH supported ftrace but didn't support DIE_OOPS, so add
that in and get it building again.

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.

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.

The pinmux management is tied in to this code, while it is presently only
used by platforms that select GENERIC_GPIO. The asm/gpio.h definitions
are not referenced when GENERIC_GPIO is disabled, resulting in a build
failure for all of the platforms that don't select it.
