d printing an exception message.

To solve the above problems, we directly compile the switch.S file into
the kernel instead of the module. In this way, the function kvm_exc_entry
will no longer need to be copied.

changlog:
V3<-V2:
1.Replace the EXPORT_SYMBOL macro declaration symbol with the
EXPORT_SYMBOL_FOR_KVM macro

2.Add some comments in kvm_enter_guest

3.Place the correct pc address in era

4.Move .p2align after .text

V2<-V1:
1.Rollback the modification of function parameter types such as
kvm_save_fpu. In the asm-prototypes.h header file, only the parameter types
it depends on are included
