Linux-2.6.12-rc2 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!

/* Physical address where kernel should be loaded. */
[PATCH] i386: Restore CONFIG_PHYSICAL_START option o Relocatable bzImage support had got rid of CONFIG_PHYSICAL_START option thinking that now this option is not required as people can build a second kernel as relocatable and load it anywhere. So need of compiling the kernel for a custom address was gone. But Magnus uses vmlinux images for second kernel in Xen environment and he wants to continue to use it. o Restoring the CONFIG_PHYSICAL_START option for the time being. I think down the line we can get rid of it. Signed-off-by: Vivek Goyal <vgoyal@in.ibm.com> Cc: "Eric W.

[PATCH] i386: Implement CONFIG_PHYSICAL_ALIGN o Now CONFIG_PHYSICAL_START is being replaced with CONFIG_PHYSICAL_ALIGN. Hardcoding the kernel physical start value creates a problem in relocatable kernel context due to boot loader limitations. For ex, if somebody compiles a relocatable kernel to be run from address 4MB, but this kernel will run from location 1MB as grub loads the kernel at physical address 1MB. Kernel thinks that I am a relocatable kernel and I should run from the address I have been loaded at. So somebody wanting to run kernel from 4MB alignment location (for improved performance regions) can't do that. o Hence, Eric proposed that probably CONFIG_PHYSICAL_ALIGN will make more sense in relocatable kernel context. At run time kernel will move itself to a physical addr location which meets user specified alignment restrictions.
