| |
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
