Move the following sysctl tables into arch/x86/kernel/setup.c:
panic_on_{unrecoverable_nmi,io_nmi}
bootloader_{type,version}
io_delay_type
unknown_nmi_panic
acpi_realmode_flags
Variables moved from include/linux/ to arch/x86/include/asm/ because there
is no longer need for them outside arch/x86/kernel:
acpi_realmode_flags
panic_on_{unrecoverable_nmi,io_nmi}
Include <asm/nmi.h> in arch/s86/kernel/setup.h in order to bring in
panic_on_{io_nmi,unrecovered_nmi}.
This is part of a greater effort to move ctl tables into their
respective subsystems which will reduce the merge conflicts in
kerenel/sysctl.c.
