In old days, Kbuild always used an absolute path for $(srctree).
Since commit 890676c65d ("kbuild: Use relative path when building in
the source tree"), $(srctree) is '.' when O= was not passed from the
command line.
Yet, using absolute paths is useful in some cases even without O=, for
instance, to create a cscope file with absolute path tags.
'O=.' was known to work as a workaround to force Kbuild to use absolute
paths even when you are building in the source tree.
Since commit 25b146c5b8 ("kbuild: allow Kbuild to start from any
directory"), Kbuild is too clever to be tricked. Even if you pass 'O=.'
Kbuild notices you are building in the source tree, then use '.' for
$(srctree).
So, 'make O=. cscope' is no help to create absolute path tags.
We cannot force one or the other according to commit e93bc1a0ca
("Revert "kbuild: specify absolute paths for cscope""). Both of
relative path and absolute path have pros and cons.
This commit adds a new flag KBUILD_ABS_SRCTREE to allow users to
choose the absolute path for $(srctree).
'make KBUILD_ABS_SRCTREE=1 cscope' will work as a replacement of
'make O=. cscope'.

I thought this script was run via "make tags" etc. but some people
run it directly.
Prior to commit a9a49c2ad9 ("kbuild: use $(srctree) instead of
KBUILD_SRC to check out-of-tree build"), in such a usecase, "tree"
was set empty since KBUILD_SRC is undefined. Now, "tree" is set to
"${srctree}/", which is evaluated to "/".
Fix it by taking into account the case where "srctree" is unset.

KBUILD_SRC was conventionally used for some different purposes:
[1] To remember the source tree path
[2] As a flag to check if sub-make is already done
[3] As a flag to check if Kbuild runs out of tree
For [1], we do not need to remember it because the top Makefile
can compute it by $(realpath $(dir $(lastword $(MAKEFILE_LIST))))
[2] has been replaced with self-commenting 'sub_make_done'.
For [3], we can distinguish in-tree/out-of-tree by comparing
$(srctree) and '.'
This commit converts [3] to prepare for the KBUILD_SRC removal.

We're already using a union of many fields here, so stop abusing the
_mapcount and make page_type its own field. That implies renaming some of
the machinery that creates PageBuddy, PageBalloon and PageKmemcg; bring
back the PG_buddy, PG_balloon and PG_kmemcg names.
As suggested by Kirill, make page_type a bitmask. Because it starts out
life as -1 (thanks to sharing the storage with _mapcount), setting a page
flag means clearing the appropriate bit. This gives us space for probably
twenty or so extra bits (depending how paranoid we want to be about
_mapcount underflow).

scripts/tags.sh: Teach tags about more powerpc macros
The emacs rules were constantly lagging behind the exuberant ones. Use a
single set of rules for both, to make the script easier to maintain.
The language understood by both tools is basic regular expression with
some limitations, which are documented in a comment. To be able to store
the rules in an array and easily iterate over it, the script requires
bash now. In the exuberant case, the change fixes some false matches in
<linux/page-flags.h> and also some too greedy matches in the arguments
of the DECLARE_*/DEFINE_* macros. In the emacs case, several previously
not working rules are matching now. Tested with these versions of the
tools:

This allows to apply the same patters to both source and header files.
The effect is mostly visible in the case of DECLARE_BITMAP, but there
are small gains all over the place. There is also lots of random changes
in the diff, I believe this is simply because there are still lots of
unexpanded macros in the code and the C and C++ parsers fail and recover
at different points. Also, qconf.h is parsed as C, but that's a
negligible regression.

Since commit 22d651dcef ('selftests/powerpc:
Import Anton's memcpy / copy_tofrom_user tests'), some source files in the
tree appear as symlink.
Until commit 8c38a5328a ('scripts/tags.sh:
ignore code of user space tools'), those symlinks made cscope report some
warnings:
$ make ALLSOURCE_ARCHS=all O=./obj-cscope/ cscope
GEN cscope
cscope: cannot find
file .../tools/testing/selftests/powerpc/copyloops/copyuser_power7.S
cscope: cannot find
file .../tools/testing/selftests/powerpc/copyloops/memcpy_64.S
cscope: cannot find
file .../tools/testing/selftests/powerpc/copyloops/memcpy_power7.S
cscope: cannot find
file .../tools/testing/selftests/powerpc/copyloops/copyuser_64.S
In order to prevent the same kind of warnings to be triggered by future
addition of symlinks, the best option is to ignore all symlinks when
building the file list to be processed by cscope (and other tools
supported by scripts/tags.sh).
Ignoring symlinks won't hide source files from cscope (and others) as the
target of these symlinks already appear somewhere else in the tree, and,
as such, should be processed by cscope (or others).
Note that, cscope, when used with -R option to make it find the files to
process by itself, already skip symlinks: it's not expected that cscope
access source files through symlink.
On top of commit 8c38a5328a ('scripts/tags.sh:
ignore code of user space tools'), scripts/tags.sh output from
"make cscope tags TAGS" is the same with and without this patch: it doesn't
seems to introduce any regression (on Fedora 20).
