New field acpi_rsdp_addr, which has been introduced in boot protocol v2.14 [1], in boot parameters tells kernel the exact address of RDSP ACPI table. Knowing it increases robustness of the kernel by avoiding in some cases traversal through a part of physical memory. It will slightly reduce boot time by the same reason. [1] See Linux kernel commit 2f74cbf ("x86/boot: Add the ACPI RSDP address to struct setup_header::acpi_rdsp_addr") @ https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=2f74cbf for the details.
