APIC IDs may not be consecutive and start from zero, so we cannot really use it
...
as a direct index into cpus. Record apicid in struct cpu and have cpunum() look
for it. Replace cpu->id with cpunum() everywhere, and replace cpu->id with cpu->apicid.
Thanks to Xi Wang.

Remove console input.lock
...
Use cons.lock for everything. This eliminates the possibility that two CPUS
independently, simultaneously manipulate the CRTC in cgaputc.

make new code like old code
...
Variable declarations at top of function,
separate from initialization.
Use == 0 instead of ! for checking pointers.
Consistent spacing around {, *, casts.
Declare 0-parameter functions as (void) not ().
Integer valued functions return -1 on failure, 0 on success.
