From: Jisheng Zhang <[email protected]>
Subject: kexec: make crashk_res, crashk_low_res and crash_notes symbols always visible

Patch series "kexec: use IS_ENABLED(CONFIG_KEXEC_CORE) instead of #ifdef", v2.

Replace the conditional compilation using "#ifdef CONFIG_KEXEC_CORE" by a check for "IS_ENABLED(CONFIG_KEXEC_CORE)", to simplify the code and increase compile coverage.

I only modified x86, arm, arm64 and riscv, other architectures such as sh, powerpc and s390 are better to be kept kexec code as-is so they are not touched.

This patch (of 5):

Make the forward declarations of crashk_res, crashk_low_res and crash_notes always visible. Code referring to these symbols can then just check for IS_ENABLED(CONFIG_KEXEC_CORE), instead of requiring conditional compilation using an #ifdef, thus preparing to increase compile coverage and simplify the code.
