Subject: [PATCH RESEND 8/8] mm: Remove mmap_legacy_base and mmap_compat_legacy_code fields from mm_struct
Date: Thu, 20 Jun 2019 01:03:28 -0400 [thread overview]
Message-ID: <20190620050328.8942-9-alex@ghiti.fr> (raw)
In-Reply-To: <20190620050328.8942-1-alex@ghiti.fr>
Now that x86 and parisc do not use those fields anymore, remove them from
mm code.
