Alexandre Chartre	8308fd0019	objtool: Add Function to get the name of a CPU feature ... Add a function to get the name of a CPU feature. The function is architecture dependent and currently only implemented for x86. The feature names are automatically generated from the cpufeatures.h include file.

Ard Biesheuvel	c3cb6c158c	objtool: Allow arch code to discover jump table size ... In preparation for adding support for annotated jump tables, where ELF relocations and symbols are used to describe the locations of jump tables in the executable, refactor the jump table discovery logic so the table size can be returned from arch_find_switch_table().
