Subject: [PATCH v2 1/4] x86: Update boot parameters defination
Date: Tue, 14 May 2019 13:09:57 +0800 [thread overview]
Message-ID: <20190514050959.21093-2-kasong@redhat.com> (raw)
In-Reply-To: <20190514050959.21093-1-kasong@redhat.com>
Since kernel commit e6e094e053af75 ("x86/acpi, x86/boot: Take RSDP address
from boot params if available"), kernel accept a acpi_rsdp_addr param in
boot_params. Sync the x86_linux_param_header to support this param.
