in theory the git merges could be generated as a flat series of patch
files:

x86.git.foo-fixes.patch
x86.git.bar-updates.patch
x86.git.foo-fixes-feh.patch
...

which could also include the commit log. "git-log -p" might be a
suitable generator. For example, x86.git can be processed per commit,
via this script:

for N in `git-rev-list --reverse --no-merges --remove-empty master..mm`; do
git-log -p $N
done

the following git-export-quilt script (just wrote it, might be buggy, so
careful - and it blows away the patches/ directory wherever you run it)
will generate a series file into patches/series that can be applied via
quilt:

rm -rf patches
mkdir patches
for N in `git-rev-list --reverse --no-merges --remove-empty master..mm`; do
git-log -p -1 $N > .tmp
export SUBJECT=`head -5 .tmp | tail -1`

# generate filename out of subject line:
FILE=x86.git-"`echo $SUBJECT | cut -c10- |
tr '[:punct:] \t' '-' | tr -s - | tr '[:upper:]' '[:lower:]'`"

# generate unique name:
while [ -f patches/$FILE.patch ]; do FILE="$FILE"_; done

echo $FILE.patch
mv .tmp patches/$FILE.patch
echo $FILE.patch >> patches/series
done

ls -l patches/series

i ran this script over x86.git and it produced a patch series with 247
patches that quilt was able to push correctly. (in theory this concept
should work for other git trees too - but i have not tried it)

this would increase the series size quite substantially though - but it
would make cherry-picking and patch based bisection a lot easier.
