This is preparatory work for allowing the kernel to be built as a PIE executable, which relies mostly on RIP-relative symbol references from code, which don't need to be updated when a binary is loaded at an address different from its link time address. Most changes are quite straight-forward, i.e., just adding a (%rip) suffix is enough in many cases. However, some are slightly trickier, and need some minor reshuffling of the asm code to get rid of the absolute references in the code. Tested with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y on a x86 CPU that implements AVX, AVX2 and AVX512.
