This patch adds some configuration options that allow to compile out
CPU vendor-specific code in x86 kernels (in arch/x86/kernel/cpu). The
new configuration options are only visible when CONFIG_EMBEDDED is
selected, as they are mostly interesting for space savings reasons.
An example of size saving, on x86 with only Intel CPU support:
text data bss dec hex filename
1125479 118760 212992 1457231 163c4f vmlinux.old
1121355 116536 212992 1450883 162383 vmlinux
-4124 -2224 0 -6348 -18CC +/-
However, I'm not exactly sure that the Kconfig wording is correct with
regard to !64BIT / 64BIT.
applied to tip/x86/cpu, thanks Thomas. (I've done a trivial cleanup:
converted the macro to an inline.)
Peter, do you like this version of the patch or would you like further
improvements?
I'm fine with it.
I think there might still be cross-dependencies, but it doesn't break
anything old, so we can deal with that via bug reports.
The other thing that probably should be done is breaking out the
Intel-specific versus generic parts of intel_cacheinfo.c.
