The following patch defines sigcontext ABI of ColdFire.  Due to ISA
restrictions ColdFire needs different rt_sigreturn trampoline.

And due to ColdFire FP registers being 8-bytes instead of 12-bytes on
m68k, sigcontext and fpregset structures should be updated.

Regarding the sc_fpstate[16+6*8] field, it would've been enough 16
bytes to store ColdFire's FP state.  To accomodate GLIBC's libSegFault
it would'be been enough 6*8 bytes (room for the 6 non-call-clobbered
FP registers).  I set it to 16+6*8 to provide some extra space for any
future changes in the ColdFire FPU.

This patch adds several syscalls, that provide necessary
functionality to support NPTL on m68k/ColdFire.
The syscalls are get_thread_area, set_thread_area, atomic_cmpxchg_32 and
atomic_barrier.
The cmpxchg syscall is required for ColdFire as it doesn't support 'cas'
instruction.

Also a ptrace call PTRACE_GET_THREAD_AREA is added to allow debugger to
inspect the TLS storage.

Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>

This patch switches m68k to generic siginfo layout.  The custom layout
of m68k's `struct siginfo' had several issues due to not considering
aliasing of members in the union, e.g., _uid32 was at different offsets
in ._kill, ._rt and ._sigchld.

Lots of changes. Remove volatile keywords. Take the advice in the comments
and change video_slot to slot_addr. Factor out fifteen or so "channel >>
8" shifts into three shifts higher up the call graph. Make
csc_setpalette() atomic, pass the correct color values. Check for
ioremap() failure. Add missing break statement, thus fixing 24 bit console
visual (blue background bug). Remove some uninformative printk() noise.
Add a description for powerbook 140/170 graphics.
