[PATCH] x86/boot: Move detecting acpi=off in cmdline to get_rsdp_addr()

2019-02-15 Thread Chao Fan
If "acpi=off" specified in cmdline, the whole functions of acpi.c should not work, there is no need to ealy parse RSDP, so detect "acpi=off" in the very first place. Also replace magic number with macro. Signed-off-by: Chao Fan --- arch/x86/boot/compressed/acpi.c | 12 ++-- 1 file chang
