Subject: [PATCH v2 5/8] crash_core.h: include <asm/crash_core.h> if generic reservation is needed
Date: Tue, 29 Aug 2023 20:16:07 +0800 [thread overview]
Message-ID: <20230829121610.138107-6-bhe@redhat.com> (raw)
In-Reply-To: <20230829121610.138107-1-bhe@redhat.com>
In asm/crash_core.h, ARCH can provide its own macro definitions to
override DEFAULT_CRASH_KERNEL_LOW_SIZE, CRASH_ALIGN, CRASH_ADDR_LOW_MAX,
CRASH_ADDR_HIGH_MAX in <linux/crash_core.h> if needed.
Later, x86 and arm64 wil support the generic reservaton, so wrap the
including into CONFIG_ARCH_HAS_GENERIC_CRASHKERNEL_RESERVATION ifdeffery
scope to avoid compiling error in other ARCH-es which doesn't take the
generic reservation.
