Subject: [PATCH v9 1/6] arm: arm64: introduce CONFIG_HAVE_MEMBLOCK_PFN_VALID
Date: Fri, 29 Jun 2018 10:29:18 +0800 [thread overview]
Message-ID: <1530239363-2356-2-git-send-email-hejianet@gmail.com> (raw)
In-Reply-To: <1530239363-2356-1-git-send-email-hejianet@gmail.com>
Make CONFIG_HAVE_MEMBLOCK_PFN_VALID a new config option so it can move
memblock_next_valid_pfn to generic code file. All the latter optimizations
are based on this config.
The memblock initialization time on arm/arm64 can benefit from this.
