Subject: [RFC PATCH v2 12/20] powerpc/64e: Remove unneeded #ifdef CONFIG_PPC_E500
Date: Fri, 17 May 2024 21:00:06 +0200 [thread overview]
Message-ID: <f70e5249b9e6a9a06e6575aa0efbaf8ba93c3659.1715971869.git.christophe.leroy@csgroup.eu> (raw)
In-Reply-To: <cover.1715971869.git.christophe.leroy@csgroup.eu>
When it is a nohash/64 it can't be anything else than
CONFIG_PPC_E500 so remove the #ifdef as they are always true.
