Subject: [PATCH v3 2/2] resource: Make it possible to reserve memory on 64bit platform
Date: Fri, 22 Jan 2021 07:55:37 -0800	[thread overview]
Message-ID: <1611330937-22654-3-git-send-email-zhaowei1102@thundersoft.com> (raw)
In-Reply-To: <1611330937-22654-1-git-send-email-zhaowei1102@thundersoft.com>

For now "reserve=" is limitied to 32bit,not available on 64bit
platform,so we change the get_option() to get_option_ull(added in
patch: commit 4b6bfe96265e ("lib/cmdline: add new function
get_option_ull()"))
