CHECKING CUSTOM irq_tables.c:
4. CHECKING CUSTOM irq_tables.c:
checkpir.c Will verify the irq_tables.c, currently it only checks the checksum. In case of wrong
checksum, a good value is proposed, so you can edit irq_tables.c manualy and replace checksum.
Run the command like this:
make checkpir
./checkpir
make test

Do not run make checkpir and ./checkpir directly because it needs to be linked
to irq_table.o first.
