6e9766317f Documentation/sparse.txt: document context annotations for lock checking
The context feature of sparse is used with the Linux kernel sources to
check for imbalanced uses of locks.  Document the annotations defined in
include/linux/compiler.h that tell sparse what to expect when a lock is
held on function entry, exit, or both.

a887a07d51 kbuild: sparse needs CF not CHECKFLAGS
Documentation/sparse.txt tells to use:

    make C=2 CHECKFLAGS="-D__CHECK_ENDIAN__"

However, this still doesn't enable endian checks. The correct syntax is:

    make C=2 CF="-D__CHECK_ENDIAN__"

This documentation bug was introduced by the following commit:

	kbuild: clarify "make C=" build option

	Clarify the use of "make C=" in the top-level Makefile, and fix a
	typo in the Documentation file.

	Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

This `typo' was not a typo, as `CF' had been introduced much earlier, by:

    commit 7b49bb9aff

    Date:   Fri Sep 9 21:14:35 2005 +0100

	[PATCH] kbuild: CF=<arguments> passes arguments to sparse

	Allows to add to sparse arguments without mutilating makefiles - just
	pass CF=<arguments> and they will be added to CHECKFLAGS.

Update the sparse documentation to omit the -Wbitwise flag example (as it
is now passed by default), and document the kernel defines to enable
endianness checking.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
