Exclamation [Q] Hp slate 21 Kernel Compilation

Hi, I am looking to compile the hp slate 21 kernel

I Have the source code which I took from Hp Open Source at this link:
https://h20392.www2.hp.com/opensourc...Cs&prd=E2P18AA

The problem is that i don't know 3 things because the readmeFile inside the kernel is the Linux one and is not specific for the hp kernel:
1: The specific Toolchain required to build this kernel
2: The Configuration file for the HP slate 21 ( I took the one from /proc/config.gz config ) from the tablet
3: Which ARCH to choose arm,x86,ia64 etc...

ANY information like samsung kernel gives would be great

I know how to build Samsung kernels because in the readmefile that looks like this, there is enough information to know what to do:
