X-Git-Tag: v6.6.7~2762^2~21
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3b519dc878a5d19593bbb1773abedbf39a619f66;p=platform%2Fkernel%2Flinux-starfive.git

crypto: x86/crc32c - Use RIP-relative addressing

Prefer RIP-relative addressing where possible, which removes the need
for boot time relocation fixups.
