**Caller**
Name	Describe
enable_a20_kbc
enable_a20_fast
early_serial_init
probe_baud
realmode_switch_hook	Invoke the realmode switch hook if present; otherwise* disable all interrupts.
mask_all_interrupts	Disable all interrupts at the legacy PIC.
reset_coprocessor	Reset IGNNE# if asserted in the FPU.
serial_putchar	These functions are in .inittext so they can be used to signal* error during initialization.
vga_set_480_scanlines
io_check_error
mask_8259A_irq
unmask_8259A_irq
i8259A_irq_real	This function assumes to be called rarely. Switching between* 8259A registers is slow.* This has to be protected by the irq controller spinlock* before being called.
mask_and_ack_8259A	Careful! The 8259A is a fragile beast, it pretty* much _has_ to be done exactly like this (mask it* first, _then_ send the EOI, and the order of EOI* to the two 8259s is important!
restore_ELCR	ELCR registers (0x4d0, 0x4d1) control edge/level of IRQ
i8259A_shutdown
mask_8259A
unmask_8259A
probe_8259A
init_8259A	This is the 'legacy' 8259A Programmable Interrupt Controller,* present in the majority of PC/AT boxes.* plus some generic x86 specific things if generic specifics makes* any sense at all.
pit_calibrate_tsc	Try to calibrate the TSC against the Programmable* Interrupt Timer and return the frequency of the TSC* in kHz.* Return ULONG_MAX on failure to calibrate.
quick_pit_calibrate
rtc_cmos_read	Routines for accessing the CMOS RAM/RTC.
rtc_cmos_write
acpi_pic_sci_set_trigger	acpi_pic_sci_set_trigger()* use ELCR to set PIC-mode trigger type for SCI* If a PIC-mode SCI is not recognized or gives spurious IRQ7's* it may require Edge Trigger -- use "acpi_sci=edge"* Port 0x4d0-4d1 are ECLR1 and ECLR2, the Edge/Level Control
native_machine_emergency_restart	To the best of our knowledge Windows compatible x86 hardware expects* the following on reboot:* 1) If the FADT has the ACPI reboot register flag set, try it* 2) If still alive, write to the keyboard controller* 3) If still alive, write to the ACPI reboot
imcr_pic_to_apic	Handle interrupt mode configuration register (IMCR)
imcr_apic_to_pic
print_PIC
rdc321x_reset
ce4100_reset
io_serial_out
in_idx	Accessing VGA indexed registers
