Re: Patch to reorder functions in the vmlinux to a defined order

Yes, you probably don't want to have to specialcase anything there.

Short of the moving the kernel to end of the address space where
vmalloc and the fixmaps are now I don't think there is a reasonable
chunk of the address space we can use.

To my handwaving ears end of the address space sounds very good though. Is there currently any pressure on VMALLOC_RESERVE (128M)? Teaching the linker appears to be a matter of changing __KERNEL_START. That leaves actually mapping ourselves there, and... more invasiveness?

I saw you say you already have some actual relocating patches though?

Rene.
