Regression fix for powerplay on some iceland boards.
* 'drm-fixes-4.9' of git://people.freedesktop.org/~agd5f/linux:
drm/amd/powerplay: implement get_clock_by_type for iceland.
drm/amd/powerplay/smu7: fix checks in smu7_get_evv_voltages (v2)

Thou shall not send control msg from the stack,
does that mean I can send it from the RO memory area?
and it looks like the answer is no, so here's
v2 which kmemdups.

It would be nice to be able to build this code on other platforms other
than only the RPi, so add some empty macros to allow this to happen, and
turn off BROKEN as the code can now build properly thanks to Michael's
work.

If your data pool was pool 0, ceph_file_layout_from_legacy()
transform that to -1 unconditionally, which broke upgrades.
We only want do that for a fully zeroed ceph_file_layout,
so that it still maps to a file_layout_t. If any fields
are set, though, we trust the fl_pgpool to be a valid pool.

Splice read/write implementation changed recently. When using
generic_file_splice_read(), iov_iter with type == ITER_PIPE is
passed to filesystem's read_iter callback. But ceph_sync_read()
can't serve ITER_PIPE iov_iter correctly (ITER_PIPE iov_iter
expects pages from page cache).
Fixing ceph_sync_read() requires a big patch. So use default
splice read callback for now.

pm_rst, aclk_rst, pclk_rst was controlled by ROM code so the software
wasn't needed to control it again in theory. But it didn't work properly,
so we do need to do it again and add enough delay between the assert of
pm_rst and the deassert of pm_rst. The Soc intergrated with this
controller, rk3399, is still under MP test internally, so the backward
compatibility won't be a big deal.

When a LOCALINV WR is flushed, the frmr is marked STALE, then
frwr_op_unmap_sync DMA-unmaps the frmr's SGL. These STALE frmrs
are then recovered when frwr_op_map hunts for an INVALID frmr to
use.
All other cases that need frmr recovery leave that SGL DMA-mapped.
The FRMR recovery path unconditionally DMA-unmaps the frmr's SGL.
To avoid DMA unmapping the SGL twice for flushed LOCAL_INV WRs,
alter the recovery logic (rather than the hot frwr_op_unmap_sync
path) to distinguish among these cases. This solution also takes
care of the case where multiple LOCAL_INV WRs are issued for the
same rpcrdma_req, some complete successfully, but some are flushed.

The current dma_map_sg based implementation for bulk messages
computes many offsets into a single allocation multiple times in
both the create and free code paths. This is inefficient,
error prone and in fact still has a few lingering issues
with arm64.
This change replaces a small portion of that inplementation with
new code that uses a new struct vchiq_pagelist_info to store the
needed information rather then complex offset calculations.
This improved implementation should be more efficient and easier
to understand and maintain.

Don't pass a size larger than iov_len to kernel_sendmsg().
Otherwise it will cause a NULL pointer deref when kernel_sendmsg()
returns with rv < size.
DRBD as external module has been around in the kernel 2.4 days already.
We used to be compatible to 2.4 and very early 2.6 kernels,
we used to use
rv = sock_sendmsg(sock, &msg, iov.iov_len);
then later changed to
rv = kernel_sendmsg(sock, &msg, &iov, 1, size);
when we should have used
rv = kernel_sendmsg(sock, &msg, &iov, 1, iov.iov_len);
tcp_sendmsg() used to totally ignore the size parameter.
57be5bd ip: convert tcp_sendmsg() to iov_iter primitives
changes that, and exposes our long standing error.
Even with this error exposed, to trigger the bug, we would need to have
an environment (config or otherwise) causing us to not use sendpage()
for larger transfers, a failing connection, and have it fail "just at the
right time". Apparently that was unlikely enough for most, so this went
unnoticed for years.
Still, it is known to trigger at least some of these,
and suspected for the others:
[0] http://lists.linbit.com/pipermail/drbd-user/2016-July/023112.html

[3] https://ubuntuforums.org/showthread.php?t=2336150
[4] http://e2.howsolveproblem.com/i/1175162/
This should go into 4.9,
and into all stable branches since and including v4.0,
which is the first to contain the exposing change.
It is correct for all stable branches older than that as well
(which contain the DRBD driver; which is 2.6.33 and up).
It requires a small "conflict" resolution for v4.4 and earlier, with v4.5
we dropped the comment block immediately preceding the kernel_sendmsg().

We have a couple of drivers, acpi_apd.c and acpi_lpss.c,
that need to pass extra build-in properties to the devices
they create. Previously the drivers added those properties
to the struct device which is member of the struct
acpi_device, but that does not work. Those properties need
to be assigned to the struct device of the platform device
instead in order for them to become available to the
drivers.
To fix this, this patch changes acpi_create_platform_device
function to take struct property_entry pointer as parameter.

The problem was that the MEGASAS_IS_LOGICAL macro did not have braces

devices (all SCSI commands to channels 1,2,3 were returned as
SUCCESS-DID_OK by driver).

If the DC clock is disabled before the attached IDMACs are properly
stopped the IDMACs may hang the IPU or even the whole system.
Make sure the IDMACs are in safe state by disabling the planes before
removal of the DC clock.
Also set the atomic parameter to false to stop calling the atomic_begin
hook, which does nothing useful as we immediately afterwards turn off
vblank interrupts and possibly send the pending vblank event.

If a command is aborted in the kernel but not in the adapter, it might be
considered complete and its DMA memory released, but it is still alive in
the adapter, which will trigger an invalid DMA access upon its completion
(in the DMA operations to deliver the command response to the driver).
On powerpc platforms with IOMMU/EEH capabilities, the problem is observed
during PCI device removal with ongoing IO requests -- which might trigger
an EEH event very often, pointing to a 'TCE Request Page Access Error'.
In that path, which is qla2x00_remove_one(), the commands are aborted in
qla2x00_abort_all_cmds(), which does not perform an abort in the adapter
as is done in qla2xxx_eh_abort() for example.
So, this patch changes qla2x00_abort_all_cmds() to abort commands in the
adapter too, with a call to qla2xxx_eh_abort(), which already implements
all the logic to submit abort requests and handle responses.

When the driver is unloading, in qla2x00_remove_one(), there is a single
call/point in time to abort ongoing commands, qla2x00_abort_all_cmds(),
which is still several steps away from the call to scsi_remove_host().
If more commands continue to arrive and be processed during that
interval, when the driver is tearing down and releasing its structures,
it might potentially hit an oops due to invalid memory access:
Unable to handle kernel paging request for data at address 0x00000138

Before calling task_release_itt() task data is memset to zero because of
which DDP context information is lost resulting in incorrect DDP
resource cleanup, to fix this call task_release_itt() before memset.

The new mpu3050 driver fails to build if I2C is disabled:
drivers/iio/built-in.o: In function `mpu3050_i2c_driver_exit':
mpu3050-i2c.c:(.exit.text+0x17f): undefined reference to `i2c_del_driver'
drivers/iio/built-in.o: In function `mpu3050_i2c_driver_init':
mpu3050-i2c.c:(.init.text+0x215): undefined reference to `i2c_register_driver'
This adds a Kconfig dependency to ensure we only build it when I2C
is available.

The newly added mpu3050 driver has two initializations for the
module owner, which causes a warning for 'make W=1':
include/linux/export.h:37:21: error: initialized field overwritten [-Werror=override-init]
drivers/iio/gyro/mpu3050-core.c:749:19: note: in expansion of macro 'THIS_MODULE'
This removes one of the two.
