...t, how would this work? I propose to encode metadata information about a symbol in special absolute symbols, "__sym_attr_metadata.<int>", that the linker can recognize when scanning the symbol table for an incoming object file.

I've updated the patches at http://ozlabs.org/~rusty/paravirt/?mf=33ba6c4fce13;path=/ to carve out the basic shape of how I see all this fitting together. These patches implement an initial set of Xen paravirt ops, as well as adapting head.S to set up a Xen-specific entrypoint. The head.S code does absolutely minimal setup, and then calls xen_start_kernel(). This installs the Xen

This series updates the boot protocol to 2.07 and uses it to implement paravirtual booting. This allows the bootloader to tell the kernel what kind of hardware/pseudo-hardware environment it's coming up under, and the kernel can use the appropriate boot sequence code. Specifically: - Update the boot protocol to 2.07, which adds fields to specify the hardware subarchitecture and some
