Hi Yinghai,
I applied this series patches to the latest pci-next, but git am fail occured.
When I try to pull from for-pci-root-bus-hotplug branch, I found some patches missed(eg. SCI_EMULATE).
Where can I get the newest pci root bus hotplug patches?
Thanks!

should be
for-pci-split-pci-root-hp-2
or
for-pci-next-2
branch.
but
>> part6: acpi add/remove simulation
>> [PATCH 40/40] ACPI: Enable SCI_EMULATE to manually simulate physical
is not in. you need to apply that separately.
