Andrew Morton f2e576b814 i386: arch/x86/math-emu/reg_ld_str.c: fix warning
arch/x86/math-emu/reg_ld_str.c:380: warning: 'l[0]' may be used uninitialized in this function
arch/x86/math-emu/reg_ld_str.c:380: warning: 'l[1]' may be used uninitialized in this function

I can't actually spot the bug here.  There's one obvious place, but fixing
that didn't shut the warning up.

Andrew Morton cc7594e420 i386: arch/x86/math-emu/fpu_entry.c warning fix
arch/x86/math-emu/fpu_entry.c:555: warning: 'entry_sel_off.empty' is used uninitialized in this function

Presumably it's harmless, but I'll sleep better at night knowing that we
initialised it.

Roland McGrath 60b3b9af35 x86: x86 user_regset cleanup
This removes a bunch of dead code that is no longer needed now
that the user_regset interfaces are being used for all these jobs.

Roland McGrath ff0ebb23c6 x86: x86 user_regset math_emu
This converts the ptrace/signal accessors for i387 math_emu
state to the user_regset interface style, and calls these
from the old interfaces.

It also cleans up math_emulate's ptrace check to be a
single-step check, which is what it really wants.

Ingo Molnar e8d591dc71 x86: lindent arch/i386/math-emu, cleanup
manually clean up some of the damage that lindent caused.
(this is a separate commit so that in the unlikely case of
a typo we can bisect it down to the manual edits.)

Ingo Molnar 3d0d14f983 x86: lindent arch/i386/math-emu
lindent these files:
                                       errors   lines of code   errors/KLOC
 arch/x86/math-emu/                      2236            9424         237.2
 arch/x86/math-emu/                       128            8706          14.7

no other changes. No code changed:

   text    data     bss     dec     hex filename
   5589802  612739 3833856 10036397         9924ad vmlinux.before
   5589802  612739 3833856 10036397         9924ad vmlinux.after

the intent of this patch is to ease the automated tracking of kernel
code quality - it's just much easier for us to maintain it if every file
in arch/x86 is supposed to be clean.

NOTE: it is a known problem of lindent that it causes some style damage
of its own, but it's a safe tool (well, except for the gcc array range
initializers extension), so we did the bulk of the changes via lindent,
and did the manual fixups in a followup patch.

the resulting math-emu code has been tested by Thomas Gleixner on a real
386 DX CPU as well, and it works fine.

Sam Ravnborg 9a39e273d4 kbuild: fix up CFLAGS usage
Only in very rare cases is it needed to change CFLAGS
outside of arch/*/Makefile.
Fix up all wrong cases - in most cases
the use of EXTRA_CFLAGS is the only thing needed.
