x86: configuration options to compile out x86 CPU support code
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.
