linux module compilng missed folder asm

I am trying to compile a driver. Version of my kernel is 3.2.0-27-generic.

I left only includes that I need: 

#include <linux/init.h>
#include <linux/module.h>
#include <linux/kernel.h>
#include <linux/proc_fs.h>
#include <linux/pci.h>
#include <linux/delay.h>
#include <linux/dmi.h>

These headers are found. But when I try to compile I get error that asm/cache.h file is not found. When I dug dipper I found that there is no such folder as "asm", but asm-generic and it contains required headers.

It's structure of folder with headers: Why was it renamed? Because of it I can't compile another drivers. If I rename "asm-geneic "to "asm" it will lead to other missing headers. What's wrong here?

asm/cache.h is architecture dependent, there are different asm directory for different architectures

arch/powerpc/include/asm/
arch/x86/include/asm/
arch/arm/include/asm
[...]

You can't rename include/asm-generic to include/asm because your problem is that you can't reach the architecture asm folder. Try to check your .config file or set manually the ARCH variable.
