From mboxrd@z Thu Jan 1 00:00:00 1970 From: Mike Rapoport Subject: [PATCH v2 07/17] mircoblaze: drop unneeded NUMA and sparsemem initializations Date: Sun, 2 Aug 2020 19:35:51 +0300 Message-ID: <20200802163601.8189-8-rppt@kernel.org> References: <20200802163601.8189-1-rppt@kernel.org> Mime-Version: 1.0 Content-Transfer-Encoding: 8bit Return-path: Received: from mail.kernel.org ([198.145.29.99]:46848 "EHLO mail.kernel.org" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1725768AbgHBQhd (ORCPT ); Sun, 2 Aug 2020 12:37:33 -0400 In-Reply-To: <20200802163601.8189-1-rppt@kernel.org> Sender: linux-arch-owner@vger.kernel.org List-ID: To: Andrew Morton Cc: Andy Lutomirski , Baoquan He , Benjamin Herrenschmidt , Borislav Petkov , Catalin Marinas , Christoph Hellwig , Dave Hansen , Emil Renner Berthing , Ingo Molnar , Hari Bathini , Marek Szyprowski , Max Filippov , Michael Ellerman , Michal Simek , Mike Rapoport , Mike Rapoport , Palmer Dabbelt , Paul Mackerras , Paul Walmsley , Peter Zijlstra From: Mike Rapoport microblaze does not support neither NUMA not SPARSMEM, so there is no point to call memblock_set_node() and sparse_memory_present_with_active_regions() functions during microblaze memory initialization. Remove these calls and the surrounding code.
