shorneActually, I was trying to compile the kernel in debug mode05:17
shorneso I could better tie the code to the assembly05:18
shornebut got an error "unaligned opcodes"... I fixed that and am adding a patch.  The issue is the ".strings" in head.S are in executable section.  SO dwarf generation complains.05:19
