^^^^
The same sould be done for 'handle_vm86_trap', which also is called
with 'holding kernel lock'. ^^^^
This snipplet out of patch-2.1.23 shows it:
#define DO_VM86_ERROR(trapnr, signr, str, name, tsk) \
asmlinkage void do_##name(struct pt_regs * regs, long error_code) \
{ \
+ lock_kernel(); \
if (regs->eflags & VM_MASK) { \
if (!handle_vm86_trap((struct kernel_vm86_regs *) regs, error_code, trapnr)) \
^^^^
