Thanks.

My x86_64 allmodconfig build is (effectively) done like this (I am using
gcc v4.5.2):

echo CONFIG_PROFILE_ALL_BRANCHES=n >../x86_64_allmodconfig.except
echo CONFIG_DEBUG_INFO=n >>../x86_64_allmodconfig.except
echo CONFIG_X86_DECODER_SELFTEST=n >>../x86_64_allmodconfig.except
KCONFIG_ALLCONFIG=../x86_64_allmodconfig.except \
        make O=../x86_64_allmodconfig allmodconfig
make O=../x86_64_allmodconfig -j48 -s

It depends on when I find a problem.  If I find a build problem
immediately after mergeing a particular tree, I reset linux-next and use
the previous version of the tree instead.  If I do not find the problem
until after I have completely merged all the trees, I may revert a
problem commit, or add a patch (is there is an interaction between two
trees).  In the latter case I will carry the revert or patch as long as
needed.
