The use of min/max should not have been switched, and instead of
forcing at least "-j2" for builds, it is enforcing no more than two
jobs in parallel. This has drastically reduced the parallelism of the
builds.
Change this to use "max" as intended so that we do make use of
available CPUs, using at least two.

Kernel builds are a bit asymmetrical in as far as CPU and memory
resources go. Compilation itself tends to scale fairly linearly in
RAM usage per number of CPUs. However, the link phase tends to use a
fairly constant large amount of RAM and generally only one CPU.
The existing attempt to build more in parallel has mostly resulted in
too many link steps running, which ends up swapping.
Instead of dividing the CPUs by the number of targets, just divide it
by two, and assume this will at least get us some compilation
happening during the link phase of one target build.

Rather than telling gcc to make warnings as errors, and then hunting
down make rules to disable this, leave them as warnings, but invoke
gcc through a wrapper that checks the warnings against a whitelist.
The initial whitelist comes from the warnings in the current build,
all of which have been allowed through Make overrides.

The localversion detection script assumes that if there's a tag
describing the commit the toplevel Makefile would indicate what
that version is. This is usually true because Linus tags a commit
and updates the Makefile at the same time to make a release.
Unfortunately this means that any other tags made on the kernel
are ignored and not used in the localversion output.
For example, consider Linus tagged v3.0-rc5 and I have worked on
a bunch of commits based off that tag and then tagged my branch
with another tag called "changes-for-linus". Ideally I would like
to see the kernel is based off v3.0-rc5 at the tag
changes-for-linus. When localversion detects the version it
assumes that the kernel is v3.0-rc5 because a tag is on the
current commit but it doesn't confirm that the tag matches the
Makefile. It then proceeds to throw away everything after the
patch level and git commit hash from git describe output so we
lost the tag changes-for-linus and are left with:
v3.0-rc5-0003-g234ad
Instead of doing that always try to describe the tree regardless
of whether or not there is an exact match (unless we are doing
--short output and just want to put a + after the version).
Include the hash of the tag so that we get a bit more information
about the tree that was built, but be sure to throw away any tags
from Linus himself that start with v3.* so that we get output
like:
v3.0-rc5-g1561da-linus-0003-g234ad

Improve parsing of multiline macros which run beyond the available
diff context. These beyond-the-horizon macros previously caused
two distinct naughty behaviors:
- The scanner, confused by the trailing backslash, would grab
the header of the next context hunk and treat it as the last
line of the preceding macro.
- The analyzer, unable to fully reduce the macro, would blame
the patch for submitting an unbalanced or unprotected macro.

checkpatch: Handle continuation headers.
Continuation headers baffle checkpatch, as it can only operate
on one line of context at a time. When continuation headers are found,
put them up with the header they're continuing so the whole thing
can be parsed in a single line of context.
checkpatch: Don't treat diffs as patches.
The patch-header cleanup code assumed that it would only ever
see patches, which was of course hogwash. This lead to crazy
results as it tried to wrap what it thought were continuation
lines at the beginnings of raw diffs.

There's lots of "return -1;" statements in this patch - it's obscene
that this is used to indicate "some error occurred" in kernel space
rather than a real errno value - even when an existing function
(eg, request_irq) gave you an error code already.

UBSAN uses compile-time instrumentation to catch undefined behavior
(UB). Compiler inserts code that perform certain kinds of checks before
operations that could cause UB. If check fails (i.e. UB detected)
__ubsan_handle_* function called to print error message.
So the most of the work is done by compiler. This patch just implements
ubsan handlers printing errors.
GCC has this capability since 4.9.x [1] (see -fsanitize=undefined
option and its suboptions).
However GCC 5.x has more checkers implemented [2].
Article [3] has a bit more details about UBSAN in the GCC.

commit 2e50c4bef77511b42cc226865d6bc568fa7f8769 upstream.
If a text section starts out with a data blob before the first
function start label, disassembly parsing doing in recordmcount.pl
gets confused on powerpc, leading to creation of corrupted module
objects.
This was not a problem so far since the compiler would never create
such text sections. However, this has changed with a recent change
in GCC 6 to support distances of > 2GB between a function and its
assoicated TOC in the ELFv2 ABI, exposing this problem.
There is already code in recordmcount.pl to handle such data blobs
on the sparc64 platform. This patch uses the same method to handle
those on powerpc as well.

Russell King found that he had weird side effects when compiling the kernel
with hard linked ccache. The reason was that recordmcount modified the
kernel in place via mmap, and when a file gets modified twice by
recordmcount, it will complain about it. To fix this issue, Russell wrote a
patch that checked if the file was hard linked more than once and would
unlink it if it was.
Linus Torvalds was not happy with the fact that recordmcount does this in
place modification. Instead of doing the unlink only if the file has two or
more hard links, it does the unlink all the time. In otherwords, it always
does a copy if it changed something. That is, it does the write out if a
change was made.
