There's a fixup patch "riscv: Replace function-like macro by static inline function" upstream commit 121f34341d396b666d8a90b24768b40e08ca0d61 that doesn't apply to 6.6, 6.1 and 5.15. You dropped the patch "riscv: uprobes: Add missing fence.i after building the XOL buffer" last week, but it snuck back in this week.
