Subject: Announce: gcc bogus warning repository

The level of warnings in a kernel build has lately increased to the 
point where it is hiding bugs and otherwise making life difficult.

In particular, recent gcc versions throw warnings when it thinks a 
variable "MAY be used uninitialized", which is not terribly helpful due 
to the fact that most of these warnings are bogus.

For those that may find this valuable, I have started a git repo that 
silences these bogus warnings, after careful auditing of code paths to 
ensure that the warning truly is bogus.

The results may be found in the "gccbug" branch of
git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/misc-2.6.git

This repository will NEVER EVER be pushed upstream.  It exists solely 
for those who want to decrease their build noise, thereby exposing true 
bugs.

The audit has already uncovered several minor bugs, lending credence to 
my theory that too many warnings hides bugs.
