Hi us,
	When i was compiling 2.6.38.2 kernel. Something wrong happend to me.
It shows like following.

[...]
Warning: call to 'copy_from_user_overflow' declared with attribute warning:
copy_from_user buffer size is not provably correct.
[...]

See http://s1202.photobucket.com/albums/bb364/harrywei/Kernel/?action=view&current=report_bug.png for details.
	I tried to fix this warning, but i don't know how to deal with
it. Can anyone help me.

Thanks.
Harry Wei.
