Re: [PATCH 6/6] x86: kaslr: relocate base offset at boot

[H. Peter Anvin]

Well... G**** is it's own problem (doing actively broken thinks for political reasons), but the real issue mostly is that there are a lot of them simply because there are a lot of ways one may want to load the kernel.

This is why things like decompression and the BIOS and EFI stubs are part of the kernel and not the bootloader.  In this case moving the randomization into the decompressor send like the right thing to do - C code, and no additional copy.
