Merge patch series "Zbb string optimizations"

Heiko Stuebner <heiko@sntech.de> says: From: Heiko Stuebner <heiko.stuebner@vrull.eu> This series still tries to allow optimized string functions for specific extensions. The last approach of using an inline base function to hold the alternative calls did cause some issues in a number of places So instead of that we're now just using an alternative j at the beginning of the generic function to jump to a separate place inside the function itself. * b4-shazam-merge: RISC-V: add zbb support to string functions RISC-V: add infrastructure to allow different str* implementations Link: https://lore.kernel.org/r/20230113212301.3534711-1-heiko@sntech.de Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
