[PATCH] i386: Update sys_vm86 to cope with changed pt_regs and %gs usage
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.
