FYI git am complains while applying this patch about whitespace issues:
Applying: riscv: Introduce riscv_v_vsize to record size of Vector context
Using index info to reconstruct a base tree...
M arch/riscv/kernel/cpufeature.c
.git/rebase-apply/patch:90: new blank line at EOF.
+
warning: 1 line adds whitespace errors.
Falling back to patching base and 3-way merge...
Thanks,
Conor.
