In the process of rewriting the x86 setup code, I found a number of inaccuracies and outdated recommendations in the boot protocol documentation. Revamp to make it more up to date. In particular, the common use of the heap actually requires (slightly) more than 4K of heap plus stack, which is the recommended amount in the document; currently the code compensates by being smaller than specified, but we can't assume that will be true forever. Thus, recommend that if we have a modern bzImage kernel, that the bootloader maximizes the available space. Signed-off-by: NH.

Because the command line is increased to 2048 characters after 2.6.21, it's not possible for boot loaders and userspace tools to determine the length of the command line the kernel can understand. The benefit of knowing the length is that users can be warned if the command line size is too long which prevents surprise if things don't work after bootup. This patch updates the boot protocol to contain a field called "cmdline_size" that contain the length of the command line (excluding the terminating zero). The patch also adds missing fields (of protocol version 2.05) to the x86_64 setup code.

Extend bzImage protocol to enable bootloaders to load a completely relocatable bzImage. Now protected mode component of kernel is also relocatable and a boot-loader can load the protected mode component at a differnt physical address than 1MB. (If kernel was built with CONFIG_RELOCATABLE) Kexec can make use of it to load this kernel at a different physical address to capture kernel crash dumps.

Claim an ID number for Xen in the LOADER_TYPE field. Also, keep the table in zero-page.txt consistent with boot.txt. [hpa says: 6 was skipped because I couldn't rule out that it hadn't been unofficially used. It seemed easier to skip it for now.] Signed-off-by: NJeremy Fitzhardinge <jeremy@xensource.com> Acked-by: N"H.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
