tor fingered the commit 578270b "block: fix segment split".
If I reverted this patch on top of 4.4-rc3 and everything seems to
work fine.
Anyone have any ideas?
FWIW, the 2 patches mentioned in a related thread [1] are already
part of Linux 4.4-rc3.

Hello all,
This patch series contains a series of small bug fixes for the arm_pmu
drivers.
I think all the patch should be backported to stable but I have not figured
out up to which version.
Julien Grall (3):
drivers/perf: arm_pmu: Fix reference count of a device_node in
of_pmu_irq_cfg

introduces new helpers to retrieve the
information from the different drivers in order to avoid duplication of the
parsing code.
To make the merge easier via the different trees, each patch modifies
a single subsystem.
For all the changes see the different patches.

information from the tables.
For now, a single global variable is used, but more will be added in a
subsequent patch. To make clear they are ACPI specific, gather all the

For consistency, the RB-tree reserved_binding_list should be initialized
