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! 2005-04-16 15:20:36 -07:00			`#ifndef _x8664_SETUP_H`

[PATCH] x86_64: 2048-byte command line Current implementation allows the kernel to receive up to 255 characters from the bootloader. While the boot protocol allows greater buffers to be sent. In current environment, the command-line is used in order to specify many values, including suspend/resume, module arguments, splash, initramfs and more. 255 characters are not enough anymore. After edd issue was fixed, and dynammic kernel command-line patch was accepted, we can extend the COMMAND_LINE_SIZE without runtime memory requirements.

[x86] remove uses of magic macros for boot_params access Instead of using magic macros for boot_params access, simply use the boot_params structure. Signed-off-by: H. Peter Anvin <hpa@zytor.com> 2007-10-15 17:13:22 -07:00			`#ifdef __KERNEL__`
