Can I just remove code of other architectures and get a clean X86 source

Can I just remove code of other architectures and get a clean X86 source

     Hi everyone.
     I am just reading the kernel code, adding some code to make it 
pause and print some text and then interact with it a little bit. I have 
compile the kernel successfully and run the kernel in QEMU. It did 
work.Nice.
     But, when I reading the source, I found that there are just too 
many files there, which make it hard for me to manage. With so many 
files, It's hard to change directories, read and modified and still 
remember what you are doing (so many files with the same/similar name).
     I know that's because Linux support many architectures, and that 's 
the reason why there are so many folders under the 'arch' directory of 
the source code.
     So, I wonder, as I only want the source for x86 device, can I 
simply remove that source files which are unrelated to x86 and still 
make the kernel work as normal? I mean, can I just remove all the 
directory under 'arch' except 'x86-64' ? Also, are there any other files 
that I can safely removed and won't hurt the kernel ?
     Thanks in advance.
     (btw, I don't know whether this question is asked before. I google 
it but find nothing related. If it's duplicated, please give me some 
pointer to the mailing list where this topic located )

Navigate with cscope only on one architecture:

make ARCH=arm cscope
