Subject: [PATCH v3 05/18] powerpc/pseries: move pseries_lpar_register_process_table() out from hash specific code
Date: Fri, 22 Oct 2021 08:30:00 +1000 [thread overview]
Message-ID: <20211021223013.2641952-6-npiggin@gmail.com> (raw)
In-Reply-To: <20211021223013.2641952-1-npiggin@gmail.com>
This reduces ifdefs in a later change making hash support configurable.
