Subject: [PATCH v5 2/9] crash_dump: Make elfcorehdr address/size symbols always visible
Date: Wed, 11 Aug 2021 10:51:00 +0200	[thread overview]
Message-ID: <ba965ca613c0cc82c1ec2fe353ee34fb13b36474.1628670468.git.geert+renesas@glider.be> (raw)
In-Reply-To: <cover.1628670468.git.geert+renesas@glider.be>

Make the forward declarations of elfcorehdr_addr and elfcorehdr_size,
and the definitions of ELFCORE_ADDR_MAX and ELFCORE_ADDR_ERR always
available, like is done for phys_initrd_start and phys_initrd_size.
Code referring to these symbols can then just check for
IS_ENABLED(CONFIG_CRASH_DUMP), instead of requiring conditional
compilation using an #ifdef, thus preparing to increase compile
coverage.

Suggested-by: Rob Herring <robh+dt@kernel.org>

  - Make ELFCORE_ADDR_{MAX,ERR} visible, too,
