Re: [Qemu-devel] [PATCH v2] linux-user: Add AT_SECURE auxval

[Marco A L Barbosa]

For some reason send-email didn't include my comments, sorry.

Following the Peter Maydell advice we just pass through the host AT_SECURE.

This fixes https://bugs.launchpad.net/qemu/+bug/1738771

Version 1 for reference:
