From mboxrd@z Thu Jan 1 00:00:00 1970 From: ard.biesheuvel@linaro.org (Ard Biesheuvel) Date: Mon, 11 Jan 2016 14:18:56 +0100 Subject: [PATCH v3 03/21] arm64: pgtable: add dummy pud_index() and pmd_index() definitions In-Reply-To: <1452518355-4606-1-git-send-email-ard.biesheuvel@linaro.org> References: <1452518355-4606-1-git-send-email-ard.biesheuvel@linaro.org> Message-ID: <1452518355-4606-4-git-send-email-ard.biesheuvel@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Add definitions of pud_index() and pmd_index() for configurations with fewer than 4 resp. 3 translation levels. This makes it easier to keep the users (e.g., the fixmap init code) generic.
