Not sure if it applies here, but in a lot of cases, one can extract the
parts that do conflict and put those patches first in the series, and
merge them together before the pull request.

The classic example of this is two independent features A and B that
both contain some cleanup. By moving the cleanup first, you can merge
the cleanup-A patches with the cleanup-B patches and submit them as one
branch, and then have feature A on top of cleanup-A merge cleanly with
both feature-B (because there are no conflicts) and with cleanup-A-B
(because cleanup-A-B has already resolved the conflict).

Unrelated to this: The mach/id.h removal seems to have caused a few
build errors in the for-next tree with u8500_defconfig. Can you have
a look at what went wrong there?
