Handle floating point state better in ptrace. The code now correctly
distinguishes between PTRACE_[GS]ETFPREGS and PTRACE_[GS]ETFPXREGS.
The FPX requests get handed off to arch-specific code because that's
not generic.
get_fpregs, set_fpregs, set_fpregs, and set_fpxregs needed real
implementation
Handle floating point state in across signals correctly. UML/i386
needs to know whether the host does PTRACE_[GS]ETFPXREGS, so an
arch_init_registers hook is added, which on x86_64 does nothing.
UML doesn't save and restore floating point registers on kernel entry
and exit, so they need to be cop
The floating point fields in the pt_regs register file aren't used, so
they are deleted.

Fix core dumping of floating point state. ELF_CORE_COPY_FPREGS gets a
definitions, and as a result, dump_fpu no longer needs to exist. Also,
elf_fpregset_t needed a real definition.

These are for 2.6.24.
They are all fixes and cleanups -
signal handling, ptrace, and core dump floating point fixes
mconsole and sysrq fixes
build fixes
code cleanup

Tidy the code affected by the floating point fixes.
A bunch of unused stuff is gone, including two sigcontext.c files,
which turned out to be entirely unneeded.
There are the usual fixes -
whitespace and style cleanups
copyright updates
emacs formatting comments gone
Fix the passing of printk output back to the mconsole client. The
existing code was somewhat confused, accumulating output in a buffer,
but writing it out entirely whenever a new chunk was added. This is
fixed.
The earlier include cleanups caused linux/sysrq.h to not be included -
this is fixed
Stop including asm/user.h from libc - it seems to be disappearing from
distros. It's replaced with sys/user.h which defines
user_fpregs_struct and user_fpxregs_struct instead of user_i387_struct
and struct user_fxsr_struct on i386.
As a bonus, on x86_64, I get to dump some stupid typedefs which w

Righto, I'll take care of this.

vmalloc() returns a void pointer, so casting to (void *) is pretty pointless.
