[PATCH RFC 0/7] proposed updates to boot protocol and paravirt booting

From: Jeremy Fitzhardinge
Date: Wed Jun 06 2007 - 19:41:22 EST


This series:
1. Updates the boot protocol to version 2.07
2. Clean up the existing build process, to get rid of tools/build and
make the linker do more heavy lifting
3. Make the bzImage payload an ELF file. The bootloader can extract
this as a naked ELF file by skipping over boot_params.setup_sects worth
of 16-bit setup code.
4. Update the boot_params to 2.07, and update the kernel's head.S to
jump to the appropriate subarch-specific kernel entrypoint. The
very earliest code is common (copy boot_params, clear bss); the
split happens just before the initial pagetable setup.
+ random little changes to make it all hang together

This boots native for me, so everything basically works. But I haven't
tested it end-to-end yet, because I haven't done the Xen bits yet.
Perhaps Rusty can do the lguest version to verify that its all sound in
principle (hint hint ;).

So, how does it look?
