Hao,

The rule is to use the same exact directory structure for .bbappend in our 
layer, as the original .bb recipe in the original layer. Also, it has to have 
the proper version in the name. So, check where the original oprofile recipe 
is located (oe-core/meta/recipes-kernel/oprofile), which version you are using 
(0.9.7) and that will give you the .bbappend name and location:

meta-arago/meta-arago-distro/recipes-kernel/oprofile/oprofile_0.9.7.bbappend

As the name suggests, this file is "appended" to the original recipe, so you 
have a way to overwrite or change anything that is set in the original recipe:

PR_append = "-arago0"
RRECOMMENDS_${PN} = ""

The first line is to update the PR and indicate it has been arago-modified.

PS. This is exactly why this kind of discussion shouldn't be done in private, 
as I keep explaining about bbappend to your team-mates over and over again. 
I'm copying it to meta-arago list, which your team members should be already 
subscribed to.

PS2. And if later you would like to submit this to meta-arago, I'd suggest 
making it conditional for your platform, so others would still get the 
original behaviour:

PR_append = "-arago0"
KERNELIMAGE = "kernel-vmlinux"
KERNELIMAGE_keystone = ""
RRECOMMENDS_${PN} = "${KERNELIMAGE}"
