Subject: [PATCH RESEND v5 07/10] x86, cleanup: Store crash memory ranges kexec_info
Date: Fri, 11 Apr 2014 10:23:28 +0800 [thread overview]
Message-ID: <1397183011-1526-8-git-send-email-chaowang@redhat.com> (raw)
In-Reply-To: <1397183011-1526-1-git-send-email-chaowang@redhat.com>
Add two new members to kexec_info structure:
struct memory_range *crash_range
int nr_crash_ranges;
crash_range contains the memory ranges used to boot 2nd kernel.
nr_crash_ranges contains the count of the crash memory ranges.
