Hi,

I want to write a kernel module which depends on the kernel type (32 or 64 bit). There are some lines of code which I want to be included in the module if and only if the kernel is 32 bit and some lines of code which should be included if kernel is 64 bit.

Is there anything like #if LINUX_VERSION_CODE < KERNEL_VERSION(2,6,26) for this case ?

I know we have CONFIG_X86_64 and CONFIG_X86_32 for  x86 architecture but how do I exactly check it in my module code?

User space program may test the arch on the fly by `uname -m`. However, I don't know the counter part in the kernel space.
