Subject: [PATCH v13 01/14] ARM: mm: add missing pud_page define to 2-level page tables
Date: Wed, 17 Mar 2021 16:23:49 +1000 [thread overview]
Message-ID: <20210317062402.533919-2-npiggin@gmail.com> (raw)
In-Reply-To: <20210317062402.533919-1-npiggin@gmail.com>
ARM uses its own PMD folding scheme which is missing pud_page which
should just pass through to pmd_page. Move this from the 3-level
page table to common header.
