As mentioned by Alex "git am -3" is basically parsing + the second part 
of rebase.  So, based on Alex's recipe, here is a possible alias for 
cherry-pick-all:

[alias]
	cherry-pick-all = "!f() { git format-patch -k --stdout --full-index 
`git symbolic-ref HEAD`..$1 | git am -k -3 --binary; }; f"

More useful (just because it is more generic) than "the second part of 
git rebase", a "sequencer" would be "the second part of git rebase -i", 
applying a custom script coming from stdin.  If that was present, git 
cherry-pick-all could be done like this:

git log --pretty=tformat:'pick %h' master..topic | git sequencer

And here is yet another alternative, that however would only work only 
if the patches applies perfectly:

git log --pretty=format:%h master..topic | xargs -rn1 git cherry-pick
