2cff4abf08 Gitbook Links: replace old links with new ones
The old links didn't point to valid locations.
Replace the old links with the new links and test those changes with a
small script: https://github.com/initBasti/markdown_link_check .

______________________________________________________________

In order to find and replace the links, I used the following commands:

grep -rwohP '.' -e "\(https\:\/\/0xax.gitbooks.io\/\S*\)" > links.txt
(Find all links recursivly in the project directories and print out the
 only the matches links)

Within links.txt:
Remove the '(' & ')' => :%s/\(//g  and :%s/\)//g
Remove duplicates => :sort u

Test if the links work with:
python3 md_link_check.py --pattern 0xax.gitbook --output-file bad.txt
(https://github.com/initBasti/markdown_link_check)

Create replace commands:
:%s/.*/grep -rl & '.' | xargs sed -i 's#&##g'
Enter replacement URL between the 2nd & 3rd '#'
Execute commands: :w !sh

a327d7237b linux-interrupts-2: rework pm jump part
Shorten the sentence to reduce repetition, as the correlation with the boot chapter
is already explained in the previous sentence.
Add 'function' to `protected_mode_jump`

s/We already know from the earliest parts that entry to protected mode is located
  in the `boot_params.hdr.code32_start` and you can see that we pass the entry of
  the protected mode and `boot_params` to the `protected_mode_jump`
 /The entry to protected mode is located in the `boot_params.hdr.code32_start`
  and passed together with the `boot_params` to the `protected_mode_jump` function/

Correct grammatical errors:
s/in the end of the/at the end of/

Improve word choices:
s/gets these two parameters in the/receives these two parameters within the/

Add missing punctuation and add filling words for a more fluent reading.

This commit introduced a new way of annotating functions: (https://lkml.org/lkml/2019/1/30/374)
