Subject: [RFC PATCH 0/5] kexec: use IS_ENABLED(CONFIG_KEXEC_CORE) instead of #ifdef
Date: Fri, 3 Dec 2021 13:11:52 +0800 [thread overview]
Message-ID: <20211203051157.2160-1-jszhang@kernel.org> (raw)
Replace the conditional compilation using "#ifdef CONFIG_KEXEC_CORE"
by a check for "IS_ENABLED(CONFIG_BLK_DEV_INITRD)", to simplify the
code and increase compile coverage.
I only modifies x86, arm, arm64 and riscv, other arch are not touched.
If the idea is accepted, I will modify all architectures code.
Jisheng Zhang (5):
kexec: make crashk_res, crashk_low_res and crash_notes symbols always
visible
riscv: mm: init: use IS_ENABLED(CONFIG_KEXEC_CORE) instead of #ifdef
x86/setup: use IS_ENABLED(CONFIG_KEXEC_CORE) instead of #ifdef
arm64: mm: use IS_ENABLED(CONFIG_KEXEC_CORE) instead of #ifdef
arm: use IS_ENABLED(CONFIG_KEXEC_CORE) instead of #ifdef
