General informations

The Linux kernel configuration item CONFIG_X86_FAST_FEATURE_TESTS:

Help text

Some fast-paths in the kernel depend on the capabilities of the CPU. Say Y here for the kernel to patch in the appropriate code at runtime based on the capabilities of the CPU. The infrastructure for patching code at runtime takes up some additional space; space-constrained embedded systems may wish to say N here to produce smaller, slightly slower code.
