Zero hops in tb_path_activate before writing a new path.
This fixes the following scenario:
- Boot with a coldplugged device
- Unplug device
- Plug device back in
- PCI hotplug fails
The hotplug operation fails because our new path matches the (now
defunct) path which was setup by the firmware for the coldplugged
device. By writing zeros before writing our path configuration we can
force thunderbolt to retrain the path.

cfq_group_service_tree_add() is applying new_weight at the beginning of
the function via cfq_update_group_weight().
This actually allows weight to change between adding it to and subtracting
it from children_weight, and triggers WARN_ON_ONCE() in
cfq_group_service_tree_del(), or even causes oops by divide error during
vfr calculation in cfq_group_service_tree_add().
The detailed scenario is as follows:
1. Create blkio cgroups X and Y as a child of X.
Set X's weight to 500 and perform some I/O to apply new_weight.
This X's I/O completes before starting Y's I/O.
2. Y starts I/O and cfq_group_service_tree_add() is called with Y.
3. cfq_group_service_tree_add() walks up the tree during children_weight
calculation and adds parent X's weight (500) to children_weight of root.
children_weight becomes 500.
4. Set X's weight to 1000.
5. X starts I/O and cfq_group_service_tree_add() is called with X.
6. cfq_group_service_tree_add() applies its new_weight (1000).
7. I/O of Y completes and cfq_group_service_tree_del() is called with Y.
8. I/O of X completes and cfq_group_service_tree_del() is called with X.
9. cfq_group_service_tree_del() subtracts X's weight (1000) from
children_weight of root. children_weight becomes -500.
This triggers WARN_ON_ONCE().
10. Set X's weight to 500.
11. X starts I/O and cfq_group_service_tree_add() is called with X.
12. cfq_group_service_tree_add() applies its new_weight (500) and adds it
to children_weight of root. children_weight becomes 0. Calcularion of
vfr triggers oops by divide error.
weight should be updated right before adding it to children_weight.

If the device-tree specifies a max-memory-bandwidth property then the

however, this calculation is faulty for two reasons.
1. It doesn't ensure that the result is a sane value, i.e. a power of 2
and <= 32 as the rest of the code assumes.
2. It uses the displayed resolution and calculates the average bandwidth
across the whole frame. It should instead calculate the peak

Epoll on trace_pipe can sometimes hang in a weird case. If the ring buffer is
empty when we set waiters_pending but an event shows up exactly at that moment
we can miss being woken up by the ring buffers irq work. Since
ring_buffer_empty() is inherently racey we will sometimes think that the buffer
is not empty. So we don't get woken up and we don't think there are any events
even though there were some ready when we added the watch, which makes us hang.
This patch fixes this by making sure that we are actually on the wait list
before we set waiters_pending, and add a memory barrier to make sure
ring_buffer_empty() is going to be correct.

There is platform refusing to respond QR_EC when SCI_EVT isn't set

By disallowing QR_EC to be issued before the previous one has been

Note that this fix can only reduce the occurrence rate of this issue, but
this issue may still occur when such a platform doesn't clear SCI_EVT

This patch cannot fix the CLEAR_ON_RESUME quirk which also relies on

isn't set.
But this patch is still useful as it can help to reduce the number of

There is a platform refusing to respond QR_EC when SCI_EVT isn't set
(Acer Aspire V5-573G).
Currently, we rely on the behaviour that the EC firmware can respond
something (for example, 0x00 to indicate "no outstanding events") to
QR_EC even when SCI_EVT is not set, but the reporter has complained
about AC/battery pluging/unpluging and video brightness change delay
on that platform.
This is because the work item that has issued QR_EC has to wait until
timeout in this case, and the _Qxx method evaluation work item queued
after QR_EC one is delayed.
It sounds reasonable to fix this issue by:
1. Implementing SCI_EVT sanity check before issuing QR_EC in the EC
driver's main state machine.
2. Moving QR_EC issuing out of the work queue used by _Qxx evaluation
to a seperate IRQ handling thread.
This patch fixes this issue using solution 1.
By disallowing QR_EC to be issued when SCI_EVT isn't set, we are able to
handle such platform in the EC driver's main state machine. This patch
enhances the state machine in this way to survive with such malfunctioning
EC firmware.
Note that this patch can also fix CLEAR_ON_RESUME quirk which also relies
on the assumption that the platforms are able to respond even when SCI_EVT
isn't set.

correct.
Also, that is different from non-fixed device events (including

For the above reasons, make fixed button device notify callbacks run

We generally don't allow ACPI drivers to bind to ACPI device objects
that companion "physical" device objects are created for to avoid
situations in which two different drivers may attempt to handle one
device at the same time. Recent ACPI device enumeration rework
extended that approach to ACPI PNP devices by starting to use a scan
handler for enumerating them. However, we previously allowed ACPI
drivers to bind to ACPI device objects with existing PNP device
companions and changing that led to functional regressions on some
systems.
For this reason, add a special check for PNP devices in
acpi_device_probe() so that ACPI drivers can bind to ACPI device
objects having existing PNP device companions as before.

Looks like MUSB cable removal can cause wake-up interrupts to
stop working for device tree based booting at least for UART3
even as nothing is dynamically remuxed. This can be fixed by
calling reconfigure_io_chain() for device tree based booting
in hwmod code. Note that we already do that for legacy booting
if the legacy mux is configured.
My guess is that this is related to UART3 and MUSB ULPI
hsusb0_data0 and hsusb0_data1 support for Carkit mode that
somehow affect the configured IO chain for UART3 and require
rearming the wake-up interrupts.
In general, for device tree based booting, pinctrl-single
calls the rearm hook that in turn calls reconfigure_io_chain
so calling reconfigure_io_chain should not be needed from the
hwmod code for other events.
So let's limit the hwmod rearming of iochain only to
HWMOD_FORCE_MSTANDBY where MUSB is currently the only user
of it. If we see other devices needing similar changes we can
add more checks for it.

commit 65b97cf6b8 introduced in v3.7 caused a regression
by using a reversed CS_MASK thus causing omap_calculate_ecc to
always fail. As the NAND base driver never checks for .calculate()'s
return value, the zeroed ECC values are used as is without showing
any error to the user. However, this won't work and the NAND device
won't be guarded by any error code.
Fix the issue by using the correct mask.
Code was tested on omap3beagle using the following procedure
- flash the primary bootloader (MLO) from the kernel to the first
NAND partition using nandwrite.
- boot the board from NAND. This utilizes OMAP ROM loader that
relies on 1-bit Hamming code ECC.
