Such foremost reason for this post is to ask for help and would like to compile my own kernel from my xperia M2 D2306 but I find a little inconvenience is only to find a file identification from my xperia I explain what this is.
This is the tutorial I'm following:
[ULTIMATE GUIDE] [Noob Friendly] Compile your own kernel from source android
As well I follow this tutorial sony:
How to rebuild kernels for flagship Xperia devices [tutorial]
And drop tools that tell me there is a problem but tell me this:
Code:
Replace Device Name with the configuration file found at:
Source / arch / arm / configs
It's written in This Way something_DeviceCodename_user_defconfig
and I went to the specified path but can not find any file of this type

"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

information from the filename of the Xperia M2:
Code:

aosp_yukon_eagle_defconfig
How could set the name of my device before entering the kernel configuration script

You are barking at the wrong tree.
The reason there is no defconfig for M2 (yukon) is that they have not uploaded the defconfig in their Github repo.
From this site it is clear that
http://xperiafirmware.com/8-firmware/53-sony-xperia-m2-d2303/
M2's firmware is 18.x.x.x
If you check the branches on Github ,there is no branch with 18.x.x.x
Moral
That source won't work.
Instead use kernel source from the Open source center.

This one should work fine for all the M2 devices .
