Modified files:
	lib/mm         : memlock.c 

Log message:
	Unconditionaly ignore also Virtual Dynamically-linked Shared Object
	(VDSO on 32bit is VSyscall on 64bit)
	It seems it could be locked on 64bit kernels running 32bit binaries,
	but it makes troubles on real 32bit machines where mlock() returns
	error when trying to lock such map area. (0xffffe000)
	Behavior of mlockall() seems to be similar.
