grub2/0071-Make-exit-take-a-return-code.patch
Robert Marshall 7b98965227 Reverse rpmvercmp return value
RPM sort was returning kernels sorted from oldest to newest
instead of newest to oldest. Flipped the sign on the return
value to switch the order.

Subject: [PATCH 71/74] Make "exit" take a return code.
This adds "exit" with a return code. With this patch, any "exit"
command /may/ include a return code, and on platforms that support
returning with an exit status, we will do so. By default we return the
same exit status we did before this patch.
