checkpatch: ignore existing CamelCase uses from include/...
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"

clean up scary strncpy(dst, src, strlen(src)) uses
Fix various weird constructions of strncpy(dst, src, strlen(src)).
Length limits should be about the space available in the destination,
not repurposed as a method to either always include or always exclude a
trailing NULL byte. Either the NULL should always be copied (using
strlcpy), or it should not be copied (using something like memcpy).
Readable code should not depend on the weird behavior of strncpy when it
hits the length limit. Better to avoid the anti-pattern entirely.

sparsemem: add BUILD_BUG_ON when sizeof mem_section is non-power-of-2
Instead of leaving a hidden trap for the next person who comes along and
wants to add something to mem_section, add a big fat warning about it
needing to be a power-of-2, and insert a BUILD_BUG_ON() in sparse_init()
to catch mistakes.
Right now non-power-of-2 mem_sections cause a number of WARNs at boot
(which don't clearly point to the size of mem_section as an issue), but
the system limps on (temporarily, at least).
This is based upon Dave Hansen's earlier RFC where he ran into the same
issue:
