Hi Hatayama,
We are almost there. A minor nit. Why have we specified KEXEC here. This
parameter disabled_cpu_apicid does not seem to dependon CONFIG_KEXEC?
Jerry, this patch looks good to me. Does it work on your system?
Because primary user for the option is currently kexec/kdump only.
I referred to acpi_rsdp description:
acpi_rsdp= [ACPI,EFI,KEXEC]
Pass the RSDP address to the kernel, mostly used
on machines running EFI runtime service to boot the
second kernel for kdump.
Indo-san, who introduced acpi_rsdp and KEXEC tag, told me that historical reason
why KEXEC tag was introduced. disable_cpu_apicid is generic at least in the
current version, so the tag doesn't need to be specified here.
I'll post a new version soon.

Thanks.
