It's not necessary to add Reported-by's for problems encountered while
developing the series. Especially as it was my drive-by suggestion to
use __DISABLE_EXPORTS that introduced the issue in the first place :)

I'd have added it to the Makefile and just dropped the definition in
kaslr.c -- should be no reason for anything in here to use EXPORT_SYMBOL.
