<< WARNING: modpost: vmlinux.o(__ex_table+0xf80): Section mismatch in reference from the (unknown reference) (unknown) to the variable .rodata.str1.4:.LC6
>> WARNING: modpost: vmlinux.o(__ex_table+0x1150): Section mismatch in reference from the (unknown reference) (unknown) to the variable .rodata.str1.4:.LC2
FATAL: modpost: The relocation at __ex_table+0x1150 references
section ".rodata.str1.4" which is not executable, IOW
it is not possible for the kernel to fault
at that address.  Something is seriously wrong
and should be fixed.
