15964864c0 [PATCH] kbuild: fix-rR-is-now-default
`make -d help | grep Makefile` shows patterns, where make tries to rebuild
included and top makefiles.

While `make -rR is now default' commit should fix this, actually, it was just
a little janitorial.

This fix is aimed to complete cancelling implicit rules.

690a973f48 [PATCH] x86-64: Speed up dwarf2 unwinder
This changes the dwarf2 unwinder to do a binary search for CIEs
instead of a linear work. The linker is unfortunately not
able to build a proper lookup table at link time, instead it creates
one at runtime as soon as the bootmem allocator is usable (so you'll continue
using the linear lookup for the first [hopefully] few calls).
The code should be ready to utilize a build-time created table once
a fixed linker becomes available.

18e39913d4 [PATCH] Fix spurious error on TAGS target when missing defconfig
Not all architectures have a file named 'defconfig' (e.g.  powerpc).
However the make TAGS and make tags targets search such files for tags,
causing an error message when they don't exist.  This patch addresses the
problem by instructing xargs not to run the tags program if there are no
matching files.

(1) We always build PHONY targets
(2) No target, so we better build it
(3) Prerequisite is newer than target
(4) The command line stored in the file named dir/.target.cmd
    differed from actual command line. This happens when compiler
    options changes
(5) No dir/.target.cmd file (used to store command line)
(6) No dir/.target.cmd file and target not listed in $(targets)
    This is a good hint that there is a bug in the kbuild file

1ab7a1f3b4 [PATCH] headers_check: use a different default directory
`make headers_check' wants to go and write stuff in /lib/modules, which
requires root, whic is unfortunate.

In fact, there's no _particular_ reason for headers_install to put it there
either -- it can go into a subdirectory of the build tree in both cases.
It's not intended to go directly into /usr/include, which is why we didn't
put it there -- and we certainly don't want people screwing around with
symlinking to it.  It's for distributors to take away and do stuff with, so
leaving it in $(objtree) is fine, even in the headers_install case.

I picked $(objtree)/usr/include but I have no _particular_ preference
for that; it just seemed reasonable.
