A special situation may occur when a processor raises its task
priority to be greater than or equal to the level of the
interrupt for which the processor INTR signal is currently
being asserted. If at the time the INTA cycle is issued, the
interrupt that was to be dispensed has become masked (programmed
by software), the local APIC will deliver a spurious-interrupt
vector. Dispensing the spurious-interrupt vector does not affect
the ISR, so the handler for this vector should return without an EOI.

Those empty C files are there because the current Kbuild
requires Makefile to be present at those directories,
(due to arch/x86/Kbuild), which requires building some object
files. So the empty source files are there to produce empty

enter new text while the cursor is somewhere in the middle of the line

By default, since we don't have special support for control characters
we should simply ignore them. This includes both pure (single) control
characters as well as ANSI escape sequences. The most important
control character to support for basic editing is Backspace.
The terminal creates a Delete (DEL) character by default when
Backspace is pressed. It also treats the Backspace character ('\b') as
a non-destructive backspace. To create the effect of destructive
backspace we have to send the sequence "\b \b".
