Hi Laurent,

Thanks for your feedback. You are right, this is the selftest code. Here
are the traces just before the first warnings:

  arm-lpae io-pgtable: selftest: pgsize_bitmap 0x40201000, IAS 32^M
  arm-lpae io-pgtable: selftest: pgsize_bitmap 0x40201000, IAS 36^M
  arm-lpae io-pgtable: selftest: pgsize_bitmap 0x40201000, IAS 40^M

There are a number of failed selftests and warnings, and in the end the
PA-RISC machine won't boot.

I think you are right and this is how it should be; thank you for the
tips, I did not know about COMPILE_TEST. I'll resend a patch v2 right away.

Best regards,
