Subject: [PATCH v2 22/43] powerpc/32: Refactor booke critical registers saving
Date: Tue, 9 Mar 2021 12:09:48 +0000 (UTC) [thread overview]
Message-ID: <ca50c568c73091f5b9094043acab20b83e2eb7d8.1615291473.git.christophe.leroy@csgroup.eu> (raw)
In-Reply-To: <cover.1615291471.git.christophe.leroy@csgroup.eu>
Refactor booke critical registers saving into a few macros
and move it into the exception prolog directly.
Keep the dedicated transfert_to_handler entry point for the
moment allthough they are empty. They will be removed in a
later patch to reduce churn.
