Subject: [PATCHv7 04/11] kexec: Switch to __pa_symbol
Date: Tue, 10 Jan 2017 13:35:43 -0800 [thread overview]

In-Reply-To: <1484084150-1523-1-git-send-email-labbott@redhat.com>
__pa_symbol is the correct api to get the physical address of kernel
symbols. Switch to it to allow for better debug checking.
