Subject: [PATCH V2 08/12] MIPS: Align kernel load address to 64KB
Date: Sat, 27 Jan 2018 11:22:15 +0800 [thread overview]
Message-ID: <1517023336-17575-2-git-send-email-chenhc@lemote.com> (raw)
In-Reply-To: <1517023336-17575-1-git-send-email-chenhc@lemote.com>
KEXEC assume kernel align to PAGE_SIZE, and 64KB is the largest
PAGE_SIZE.
