名称描述
load_direct_gdtLoad the original GDT from the per-cpu structure
setup_getcpu
__apm_bios_call__apm_bios_call - Make an APM BIOS 32bit call*@_call: pointer to struct apm_bios_call.* Make an APM call using the 32bit protected mode interface. The* caller is responsible for knowing if APM BIOS is configured and* enabled
__apm_bios_call_simple__apm_bios_call_simple - Make an APM BIOS 32bit call (on CPU 0)*@_call: pointer to struct apm_bios_call
apm_initJust start the APM thread. We do NOT want to do APM BIOS* calls from anything but the APM thread, if for no other reason* than the fact that we don't trust the APM BIOS. This way,* most common APM BIOS problems that lead to protection errors
do_boot_cpuNOTE - on most systems this is a PHYSICAL apic ID, but on multiquad* (ie clustered apic addressing mode), this is a LOGICAL apic ID.* Returns zero if CPU booted OK, else error code from* ->wakeup_secondary_cpu.
setup_percpu_segment
get_cpu_gdt_paddrProvide the physical address of the GDT page.
