Subject[PATCH] export boottime gdt from i386/kernel/trampoline.S
FromAndrey Panin <>
Hi all,

this trivial patch (against 2.5.59) renames gdt_48 to boot_gdt and 
makes it global, idt_48 is renamed to for consistency sake.

This patch allows visws subarch to use boottime gdt for starting boot cpu.

Please consider applying.

Best regards.
