[PATCH 2/2] resource: Make it possible to reserve memory on 64bit platform

From: Wesley Zhao
Date: Mon Jan 11 2021 - 11:42:41 EST


From: "Wesley.Zhao" <zhaowei1102@xxxxxxxxxxxxxxx>

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()"))
