It's barely been more than a week, relax :)

checkpatch really does not like one of the macros you added. Please
consider whether this is valid:

ERROR: Macros with complex values should be enclosed in parentheses
#38: FILE: arch/riscv/include/asm/asm-extable.h:61:
+#define _ASM_EXTABLE_KACCESS_ERR_ZERO(insn, fixup, err, zero)          \
+       __DEFINE_ASM_GPR_NUMS                                           \
+       __ASM_EXTABLE_RAW(#insn, #fixup,                                \
+                         __stringify(EX_TYPE_KACCESS_ERR_ZERO),        \
+                         "("                                           \
+                           EX_DATA_REG(ERR, err) " | "                 \
+                           EX_DATA_REG(ZERO, zero)                     \
+                         ")")

Thanks,
Conor.
