[Xen-devel] [PATCH 0/2] xen/arm32: Use alternative to skip the check of pending serrors

[Wei Chen <Wei.Chen@xxxxxxx>]

We have provided an option to administrator to determine how to
handle the SErrors. In order to avoid add overhead to check the
option at every trap, we want to use the alternative to skip
this check.

In this series:
1. Introduce alternative patching support for ARM32.
2. Update the ARM32 SErrors handle code to use the alternative.

This series is the follow-up of the
