[0/4] [2.6 patch] better i386 CPU selection

[Adrian Bunk]

The patch is now splitted into the following four patches:

[1/4]
- changed the i386 CPU selection from a choice to single options for
  every cpu
- renamed the M* variables to CPU_*, this is needed to ask the users
  upgrading from older kernels instead of silently changing the
  semantics
- X86_GOOD_APIC -> X86_BAD_APIC
- AMD Elan is a different subarch, you can't configure a kernel that
  runs on both the AMD Elan and other i386 CPUs
- added optimizing CFLAGS for the AMD Elan
- gcc 2.95 supports -march=k6 (no need for check_gcc)
- help text changes/updates

[2/4]
move "struct movsl_mask movsl_mask" to usercopy.c 
(CONFIG_X86_INTEL_USERCOPY is used on non-Intel CPUs)

[3/4]
- made arch/i386/kernel/cpu/Makefile CPU specific

[4/4]
- made arch/i386/kernel/cpu/mtrr/Makefile CPU specific

Dependencies between these patches:
- patch 3 requires 1+2
- patch 4 requires 1

The main part is patch 1.

Patch 2 fixes a small issue that only shows up with patch 3.

Patches 3+4 add some space optimizations by omitting unneeded code. They 
are _not_ required, the main part is patch 1.


TODO:
- which CPUs exactly need X86_ALIGNMENT_16?
- change include/asm-i386/module.h to use some kind of bitmask
