Pull first stage of __cpuinit removal from Paul Gortmaker:
"The two commits here 1) dummy out all the __cpuinit macros so that we
no longer generate such sections, and then 2) remove all the section
processing that we used to do for those sections.
This makes all the __cpuinit and friends no-ops, so that we can remove
the use cases of it at our leisure. Expect stage 2, which does the
tree wide removal sweep at the end of the merge window."

Add a file to cache the CamelCase variables found by <commit> to reduce
the time it takes to scan the include/ directory.
Filename is '.checkpatch-camelcase.<commit>' and it is created only only
if a .git directory exists.
<commit> is determined by the last non-merge commit id in the
include/ path.
Reduces checkpatch run time by ~12 cpu seconds on my little netbook.

When using --strict, CamelCase uses are described with CHECK: messages.
These CamelCase uses may be acceptable and should not generate these
messages when the variable is already defined in a file from the
include/... path.
So, change checkpatch to read all the .h files in include/... and look
for preexisting CamelCase #defines, typedefs and function prototypes.
Add these to the existing camelcase hash so that any uses in the patch or
file can be ignored.
There are currently ~3500 files in include/. It takes about 10 cpu
seconds on my little netbook to grep for and preseed these existing uses.
That's about 4x the time for a similar git grep.
This preseeding is only done once when using --strict and only when there
is a CamelCase use found.
If a .git directory is found, it uses 'git ls-files include' If not, it
uses 'find $root/include -name "*.h"

Some patches have simple defects in whitespace and formatting that
checkpatch could correct automatically. Attempt to do so.
Add a --fix option to create a "<inputfile>.EXPERIMENTAL-checkpatch-fixes"
file that tries to use normal kernel style for some of these formatting
errors.
Add warnings against using this file without verifying the changes.
