Early interrupt and exception handling
--------------------------------------------------------------------------------
In the previous [part](http://0xax.gitbooks.io/linux-insides/content/Initialization/linux-initialization-1.html) we stopped before setting of early interrupt handlers. At this moment we are in the decompressed Linux kernel, we have basic [paging](https://en.wikipedia.org/wiki/Page_table) structure for early boot and our current goal is to finish early preparation before the main kernel code will start to work.

This is the end of the second part about linux kernel insides. If you have questions or suggestions, ping me in twitter [0xAX](https://twitter.com/0xAX), drop me [email](anotherworldofworld@gmail.com) or just create [issue](https://github.com/0xAX/linux-insides/issues/new). In the next part we will see all steps before kernel entry point - `start_kernel` function.
