Built and booted successfully on RISC-V RV64 (HiFive Unmatched).

There is a new warning caused by commit "riscv: uprobes: Add missing fence.i after building the XOL buffer"

arch/riscv/kernel/probes/uprobes.c: In function 'arch_uprobe_copy_ixol':
arch/riscv/kernel/probes/uprobes.c:170:23: warning: unused variable 'start' [-Wunused-variable]
   170 |         unsigned long start = (unsigned long)dst;
       |                       ^~~~~

This can be fixed by adding the upstream companion commit "riscv: Replace function-like macro by static inline function", commit id 
121f34341d396b666d8a90b24768b40e08ca0d61

Can you provide a working backport?
