The initialization of gate descriptors was changed from using
set_intr_gate_ist() to idt_setup_from_table, which initalizes the
struct idt_data def_idts[] array.

Change the description accordingly.
Replace irq_stack_union with fixed_percpu_data
Update to the current system map

Also fix a typo from a previous commit.
The irq_stack is no longer within a irq_stack_union
but separated into the irq_stack struct and the fixed_percpu_data struct
This change was made with the following series of commits:

The btsl not only tests the bit, it tests the bit
by transfering it into the carry flag and then sets
it as well. Otherwise the wrmsr would not make sense.

While reading about initcalls around the web and kernel source code I found
that the information of what happens to __init functions not explicitly set to
any initcall list pretty useful. With this patch such information is added.

This patch handle different typos present in the initcall section of the book.
It also reword some paragraphs in order to get it clearer to the reader.
Some example codes were also added in order to help the reader to understand
smaller concepts, like the way initcalls callbacks are named in the object
file.
