Ben Skeggs e432d48f87 drm/nvd0: lets not attempt to dereference a nv50_display pointer

Ken Milmore 658e86ee2d drm/nouveau: enable hwmon support when both nouveau/hwmon are built as modules.
The nouveau hwmon temperature support currently only functions when hwmon is
compiled into the kernel. There's no reason why this shouldn't also work when
both hwmon and nouveau are modularised (as is the case with Slackware's stock
kernels).

Ben Skeggs b681993f7a drm/nvd0/disp: dac load detect
VBIOS does more than this, as does nv50/nvc0 driver in nouveau.  Traces
of the NVIDIA binary driver however, show pretty much just this being
done...  Seems to work for me, it'll be fine for the moment.

We previously assumed (incorrectly a lot of the time) that PTIMER would

By programming PTIMER ourselves, we avoid this problem.

Florian Mickler fc61ccd35f [media] vp7045: fix buffer setup
dvb_usb_device_init calls the frontend_attach method of this driver which
uses vp7045_usb_ob. In order to have a buffer ready in vp7045_usb_op, it has to
be allocated before that happens.

Luckily we can use the whole private data as the buffer as it gets separately
allocated on the heap via kzalloc in dvb_usb_device_init and is thus apt for
use via usb_control_msg.

This fixes a
	BUG: unable to handle kernel paging request at 0000000000001e78

Jarod Wilson de4ed0c111 [media] nuvoton-cir: simplify raw IR sample handling
The nuvoton-cir driver was storing up consecutive pulse-pulse and
space-space samples internally, for no good reason, since
ir_raw_event_store_with_filter() already merges back to back like
samples types for us. This should also fix a regression introduced late
in 3.0 that related to a timeout change, which actually becomes correct
when coupled with this change. Tested with RC6 and RC5 on my own
nuvoton-cir hardware atop vanilla 3.0.0, after verifying quirky
behavior in 3.0 due to the timeout change.

  warning: (ISCSI_TCP && SCSI_CXGB3_ISCSI && SCSI_CXGB4_ISCSI && SCSI_QLA_ISCSI && INFINIBAND_ISER) selects SCSI_ISCSI_ATTRS which has unmet direct dependencies (SCSI && NET)

so make SCSI_QLA_ISCSI also depend on NET to prevent the build errors.

Bart Van Assche c338bfb5ec backlight: Declare backlight_types[] const
Since backlight_types[] isn't modified, let's declare it const.  That
was probably the intention of the author of commit bb7ca747f8
("backlight: add backlight type"), via which the "const char const *"
construct was introduced.  The duplicate const was detected by sparse.

NeilBrown 27a7b260f7 md: Fix handling for devices from 2TB to 4TB in 0.90 metadata.
0.90 metadata uses an unsigned 32bit number to count the number of
kilobytes used from each device.
This should allow up to 4TB per device.
However we multiply this by 2 (to get sectors) before casting to a
larger type, so sizes above 2TB get truncated.

Also we allow rdev->sectors to be larger than 4TB, so it is possible
for the array to be resized larger than the metadata can handle.
So make sure rdev->sectors never exceeds 4TB when 0.90 metadata is in
used.

Also the sanity check at the end of super_90_load should include level
1 as it used ->size too. (RAID0 and Linear don't use ->size at all).

NeilBrown 079fa166a2 md/raid1,10: Remove use-after-free bug in make_request.
A single request to RAID1 or RAID10 might result in multiple
requests if there are known bad blocks that need to be avoided.

To detect if we need to submit another write request we test:
 	if (sectors_handled < (bio->bi_size >> 9)) {

However this is after we call **_write_done() so the 'bio' no longer
belongs to us - the writes could have completed and the bio freed.

So move the **_write_done call until after the test against
bio->bi_size.

This addresses https://bugzilla.kernel.org/show_bug.cgi?id=41862

NeilBrown 19d5f834d6 md/raid10: unify handling of write completion.
A write can complete at two different places:
1/ when the last member-device write completes, through
   raid10_end_write_request
2/ in make_request() when we remove the initial bias from ->remaining.

These two should do exactly the same thing and the comment says they
do, but they don't.

So factor the correct code out into a function and call it in both
places.  This makes the code much more similar to RAID1.

The difference is only significant if there is an error, and they
usually take a while, so it is unlikely that there will be an error
already when make_request is completing, so this is unlikely to cause
real problems.

Jon Mason ed2888e906 PCI: Remove MRRS modification from MPS setting code
Modifying the Maximum Read Request Size to 0 (value of 128Bytes) has
massive negative ramifications on some devices.  Without knowing which
devices have this issue, do not modify from the default value when
walking the PCI-E bus in pcie_bus_safe mode.  Also, make pcie_bus_safe
the default procedure.

Shyam Iyer 5307f6d5fb Fix pointer dereference before call to pcie_bus_configure_settings
Commit b03e7495a8 ("PCI: Set PCI-E Max Payload Size on fabric")
introduced a potential NULL pointer dereference in calls to
pcie_bus_configure_settings due to attempts to access pci_bus self
variables when the self pointer is NULL.

To correct this, verify that the self pointer in pci_bus is non-NULL
before dereferencing it.
