86ed40bd6f sparc: unify sections.h
While doing this use standard names for start/end
so we could use definitions straight from asm-generic
for all the typical symbols.

This also allowed us to drop the use of PROVIDE in the linker
script so sprc is less non-standard on this area.

878a553595 sparc: We need to implement arch_ptrace_stop().
In order to always provide fully synchronized state to the debugger,
we might need to do a synchronize_user_stack().

A pair of hooks, arch_ptrace_stop_needed() and arch_ptrace_stop(),
exist to handle this kind of situation.  It was created for
the sake of IA64.

Use them, to flush the kernel side cached register windows
to the user stack, when necessary.

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.

Stephen Rothwell pointed out that pcmcia can't be enabled on sparc64.

There is an empty non-prompt PCMCIA explicit entry in
arch/sparc/Kconfig but that doesn't do anything.

32-bit sparc needs a small hack to make this work, since it doesn't
use the generic IRQ layer yes.  We have to provide a dummy definition
of probe_irq_mask(), since this is used by the yenta socket driver.

64f2dde3f7 sparc64: Run the kernel always in the TSO memory model.
The fact of the matter is, all UltraSPARC-III and later chips only
implement TSO.  They don't implement PSO and RMO memory models at all.

Only the Ultra-I and Ultra-II family chips implement RMO and they are
only helped marginally by using this setting when executing kernel
code.

The big plus to doing this is that we can eliminate all of the non-Sync
memory barriers in the kernel except for the ones used in the optimized
memcpy/memset code (these use block load and store operations which
have their own memory ordering rules).

83224b0837 container freezer: add TIF_FREEZE flag to all architectures
This patch series introduces a cgroup subsystem that utilizes the swsusp
freezer to freeze a group of tasks.  It's immediately useful for batch job
management scripts.  It should also be useful in the future for
implementing container checkpoint/restart.

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

* 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 patch:

The first step in making the refrigerator() available to all
architectures, even for those without power management.

The purpose of such a change is to be able to use the refrigerator() in a
new control group subsystem which will implement a control group freezer.

b70ac77185 serial: allow 8250 to be used on sparc
This requires three changes:

1) Remove !SPARC restriction in Kconfig.

2) Move Sparc specific serial drivers before 8250, so that serial
   console devices don't change names on us, even if 8250 finds
   devices.

3) Since the Sparc specific serial drivers try to use the
   same major/minor device namespace as 8250, some coordination
   is necessary.  Use the sunserial_*() layer routines to allocate
   minor number space within TTY_MAJOR when CONFIG_SPARC.

   This has no effect on other platforms.

Thanks to Josip Rodin for bringing up this issue and testing
plus debugging various revisions of this patch.

b539c46766 sparc64: Fix sparse warnings in fault.c
1) set_brkpt() is referenced by nothing and hasn't been used by anyone
   to my knowledge for many many years.  So just delete it.

2) add extern decl for do_sparc64_fault() in asm/pgtable_64.h

b0f1e7962f sparc64: Define WANT_PAGE_VIRTUAL
As sparse warns, without this struct page pointer subtraction is
extremely expensive, and this is a pretty common operation in
fast paths.

With this define struct page becomes 64 bytes which makes for a
simple subtract and shift, instead of a costly divide or reciprocol
multiply.

8f20b20de7 sparc64: Fix sparse warnings in global reg snapshotting.
Lots of shadowed local variables and global_reg_snapshot[] needs
an extern declaration in asm/ptrace_64.h.
