While waaaaay overdue, "fixes and sparse annotations" tree is finally
going public. This version is basically a starting point - there will be
much more stuff to merge.
Right now it builds with allmodconfig[1] on the following set:
alpha (UP and SMP), amd64 (UP and SMP), arm (RPC, versatile), i386, ia64,
m32r, m68k (sans sun3), ppc (6xx, 44x, chestnut), ppc64, sparc, sparc64,
s390 (31 and 64bit) and uml (i386 and amd64)[2].
Amount of sparse and gcc4 warnings is moderate on all of the
above - there's no "drowns everything in noise" stuff left. There _are_
nasty areas (drm, some of the sata, several mem* helpers with constant
arguments), but at least that's easy to isolate. Tracking build log
changes for regressions had been fairly easy so far; quite a few chunks
in there (as well as already merged stuff) had been found that way,
so for now I'd say that it's usable.
Current patchset is on ftp.linux.org.uk/pub/people/viro/ -
patch-2.6.13-git3-bird1.bz2 is combined patch, patchset/* is the splitup.
Long description of patches is in patchset/set*, short log is in the end of
this posting. Current build and sparse logs are in logs/*/{log17b,S-log17b}.
Eventually I'll probably have to use rcs for them - they are large and change
slowly...
Patchset will change pretty fast; for one thing, most of the stuff
in there is easily mergable, for another - sparse patches here are just
dealing with the most annoying noise sources. There will be more and folks
are more than welcome to send sane annotation patches for merge.
Have fun - it's just getting started...
[1] configs being tracked are of allmodconfig-with-fixed-subset variety; e.g.
alpha-UP is "set as much as possible to y or m, with CONFIG_SMP not set", etc.
See config/* for currently tracked ones.
[2] toolkit for cross-toolchains will be re-posted on anonftp pretty soon;
ditto for details on cross-build setups, etc.
Short log of the current patchset follows:
