617af66cae Fix problem that may have made 'Hello World' print more than once or ended in unusual behavior. Ensure CLI is used before calling HLT so that interrupts don't restart the code after the HLT. Also ensure that when updating SS and SP that interrupts are off during the operation. It is possible for an interrupt to occur between the instructions causing the stack state to be invalid during interrupt execution, 2015-09-14 07:08:40 +02:00

4164f58e46 Fix issue with GRUB not finding multiboot header 
Modify the linker script to move the unique GNU information in
section .note.gnu.build-id after the .multiboot section. This
prevents the mulitboot header being pushed beyond the 8k position
in the kernel image.
