Can I delete these from Kernel Source?

[scott]

I came across a fact that the kernel's source has lot of folders in it - like separate folders for SCSI drivers, another one for SPARC architecture and so on. If I don't use these, can I delete this from the kernel source or will there be any adverse impact caused by this action?

You can delete anything from kernel source, as long as you are not using the source to compile new files.
