Subject: [PATCH 06/11] kexec: Set IORESOURCE_SYSTEM_RAM to System RAM
Date: Mon, 14 Dec 2015 16:37:21 -0700	[thread overview]
Message-ID: <1450136246-17053-6-git-send-email-toshi.kani@hpe.com> (raw)
In-Reply-To: <1450136246-17053-1-git-send-email-toshi.kani@hpe.com>

Set IORESOURCE_SYSTEM_RAM to the flags of resource ranges with
"System RAM", and "Crash kernel", which is a child node of
System RAM.

Change kexec_add_buffer() to call walk_iomem_res() with
IORESOURCE_SYSTEM_RAM type for "Crash kernel".
