Question about config UPROBES and UPROBE_EVENTS

[Tiezhu Yang]

Hi Masami,

I am a little confused about config UPROBES and UPROBE_EVENTS.
Uprobes is the user-space counterpart to kprobes, I want to do
some small changes:

(1) since config KPROBES can be selectable, just make config UPROBES
    selectable too.

(2) since config KPROBE_EVENTS depends on KPROBES rather than select
    KPROBES, just make config UPROBE_EVENTS depends on UPROBES rather
    than select UPROBES.

Could you please let me know are you OK with the following changes?
If yes, I will send formal patches later.
