First off all, you should do all your work on a branch
and not on 'master'.
eg, lets assume you did some work on a branch 'some-fix'
which has 2 patches
git checkout -b some-fix
...do work..
git add -u
git commit
...do more work..
git add -u
git commit
Now you want to turn this into one single patch for submission.
git rebase -i master
....it now displays a list of patches in 'vi'...
To merge two patches into one, just change the 'pick' word
against the 2nd patch into 'squash'. This causes it to merge
the 2nd patch into the first patch and lets you update the
commit message.

If they were combined, these patches would be good.
