Oh that's wierd. riscv defines flush_icache_range() as "empty" so then this patch does nothing in these older kernels. Ah, it's an inline function in newer kernel trees as well so that the build warning isn't there anymore.
As this change feels odd for 6.6 and older kernels, AND it's causing build warnings, I'm just going to drop it and if the riscv maintainers really want it applied to these trees, will take a working backport from them.

This is the same build failure from last week. 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.
