sys_vm86 uses a struct kernel_vm86_regs, which is identical to pt_regs, but adds an extra space for all the segment registers. Previously this structure was completely independent, so changes in pt_regs had to be reflected in kernel_vm86_regs. This changes just embeds pt_regs in kernel_vm86_regs, and makes the appropriate changes to vm86.c to deal with the new naming. Also, since %gs is dealt with differently in the kernel, this change adjusts vm86.c to reflect this. While making these changes, I also cleaned up some frankly bizarre code which was added when auditing was added to sys_vm86.
