Umm. The particular PART of ACPI you depend on needs to go in first, yes.

That's the whole point of topic branches. They allow you to separate out
work to different areas, so that people who are interested in (say) the
PCI-impacting ones can merge with one part, without having to wait for the
other parts to stabilize.

The PCI tree merged the suspend branch from the ACPI tree. You can see it
by lookin gat the PCI merge in gitk:

gitk dc7c65db^..dc7c65db

and roughly in the middle there you'll find Jesse's commit 53eb2fbe, in
which he merges branch 'suspend' from Len's ACPI tree.

So Jesse got these three commits:

0e6859d... ACPI PM: Remove obsolete Toshiba workaround
8d2bdf4... PCI ACPI: Drop the second argument of platform_pci_choose_state
0616678... ACPI PM: acpi_pm_device_sleep_state() cleanup

from Len's tree. Then look at these three commits that I got when I
actually merged from you:

741438b... ACPI PM: Remove obsolete Toshiba workaround
a80a6da... PCI ACPI: Drop the second argument of platform_pci_choose_state
2fe2de5... ACPI PM: acpi_pm_device_sleep_state() cleanup

Look familiar? It's the same patches - just different commit ID's. You
rebased and moved them around, so they're not really the "same" at all,
and they don't show the shared history any more, and the fact that they
were pulled earlier into the PCI tree (and then into mine).

This is what rebasing causes.
