Ruediger Meier observed a regression with the PREVENT ALLOW MEDIUM
REMOVAL command in lk 3.19:
http://www.spinics.net/lists/util-linux-ng/msg11448.html
Inspection indicated the same regression with VERIFY(10).
The patch is against lk 3.19.3 and also works with lk 4.3.0 . With this
patch both commands are accepted and do nothing.
ChangeLog:
- fix the lk 3.19 regression so that the PREVENT ALLOW MEDIUM REMOVAL
command is supported once again
- same fix for VERIFY(10)

A device may report an OPTIMAL UNMAP GRANULARITY and UNMAP GRANULARITY
ALIGNMENT in the Block Limits VPD. These parameters describe the
device's internal provisioning allocation units. By default the block
layer will round and align any discard requests based on these limits.
If a device reports LBPRZ=1 to guarantee zeroes after discard, however,
it is imperative that the block layer does not leave out any parts of
the requested block range. Otherwise the device can not do the required
zeroing of any partial allocation units and this can lead to data
corruption.
Since the dm thinp personality relies on the block layer's current
behavior and is unable to deal with partial discard blocks we work
around the problem by setting the granularity to match the logical block
size when LBPRZ is enabled.

The common clk implementation for MMP broke without anyone noticing
when we stopped including linux/clk.h from the clk-provider header.
This did not show up in the defconfig builds because those use the
legacy MMP clk drivers, and it did not show up in my randconfig tests
either because I was testing with my mmp multiplatform series
applied, which at some point gained the fixup.
This fixes the three broken files.

Commit b3a72384fe29 ("ARM/PCI: Replace pci_sys_data->align_resource with
global function pointer") introduced an ARM-specific align_resource()
function pointer. This is not portable to other arches and doesn't work
for platforms with two different PCIe host bridge controllers.
Move the function pointer to the pci_host_bridge structure so each host
bridge driver can specify its own align_resource() function.

Commit 35a4a57 ("isdn: clean up debug format string usage") introduced
a safeguard to avoid accidential format string interpolation of data
when calling debugl1 or HiSax_putstatus. This did however not take into
account VHiSax_putstatus (called by HiSax_putstatus) does *not* call
vsprintf if the head parameter is NULL - the format string is treated
as plain text then instead. As a result, the string "%s" is processed
literally, and the actual information is lost. This affects the isdnlog
userspace program which stopped logging information since that commit.
So revert the HiSax_putstatus invocations to the previous state.

Currently a DDI port may register the DP hotplug handler even though
it's used with HDMI, and the DP HPD handler overrides the encoder
type forcibly to DP. This caused the inconsistency on a machine
connected with a HDMI monitor; upon a hotplug event, the DDI port is
suddenly switched to be handled as a DP although the same monitor is
kept connected, and this leads to the erroneous blank output.
This patch papers over the bug by excluding the previous HDMI encoder
type from this override. This should be fixed more fundamentally,
e.g. by moving the encoder type reset from the HPD or by having
individual encoder objects for HDMI and DP. But since the bug has
been present for a long time (3.17), it's better to have a
quick-n-dirty fix for now, and keep working on a cleaner fix.

The commit [cfb23ed622d0: drm/i915: Allow fuzzy matching in
pipe_config_compare, v2] relaxed the way to compare the pipe
configurations, but one new comparison sneaked in there: it added the
strict has_drrs value check. This causes a regression on many
machines, typically HP laptops with a docking port, where the kernel
spews warnings and eventually fails to set the mode properly like:
[drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in has_drrs (expected 1, found 0)
------------[ cut here ]------------
WARNING: CPU: 0 PID: 79 at drivers/gpu/drm/i915/intel_display.c:12700 intel_modeset_check_state+0x5aa/0x870 [i915]()

....
This patch just removes the check again for fixing the regression.

Since commit 3fffd1283927 ("i2c: allow specifying
separate wakeup interrupt in device tree") we have
automatic wakeup irq support for i2c devices. That
commit missed the fact that rtc-1307 had its own
wakeup irq handling and ended up introducing a
kernel splat for at least Beagle x15 boards.
Fix that by reverting original commit _and_ passing
correct interrupt names on DTS so i2c-core can
choose correct IRQ as wakeup.
Now that we have automatic wakeirq support, we can
revert the original commit which did it manually.
Fixes the following warning:

ipu_crtc_handle_pageflip() was calling drm_send_vblank_event() with
a pipe argument of -1. Commit cc1ef118fc09 ("drm/irq: Make pipe
unsigned and name consistent") now makes this error obvious, as we
now may get a warning from:
if (WARN_ON(pipe >= dev->num_crtcs))
in drm_vblank_count_and_time(). Prior to this change, we would end
up making out-of-bounds array accesses via:
struct drm_vblank_crtc *vblank = &dev->vblank[crtc];
and
*vblanktime = vblanktimestamp(dev, pipe, cur_vblank);
So, this has been broken for a very long time, and is not a result
of the above commit. Since we don't care about the staging versions,
I've tagged this with the earliest mainline commit where we do care,
even though this commit did not introduce the bug.

There's a few places where we need to access a GPC register from ucode,
but outside of the falcon's io address space. To do this we need to
calculate the offset based on which GPC we're executing on.
This used to be done manually, but we've since found a "base" offset
that can be added by the hardware. To use this, an extra bit needs to
be set in the register address, which is what this macro achieves.
There should be no functional change from this commit.

We received a bug report recently when DDW (64-bit direct DMA on Power)
is not enabled for NVMe devices. In that case, we fall back to 32-bit
DMA via the IOMMU, which is always done via 4K TCEs (Translation Control
Entries).
The NVMe device driver, though, assumes that the DMA alignment for the
PRP entries will match the device's page size, and that the DMA aligment
matches the kernel's page aligment. On Power, the the IOMMU page size,
as mentioned above, can be 4K, while the device can have a page size of
8K, while the kernel has a page size of 64K. This eventually trips the
BUG_ON in nvme_setup_prps(), as we have a 'dma_len' that is a multiple
of 4K but not 8K (e.g., 0xF000).
In this particular case of page sizes, we clearly want to use the
IOMMU's page size in the driver. And generally, the NVMe driver in this
function should be using the IOMMU's page size for the default device
page size, rather than the kernel's page size. There is not currently an
API to obtain the IOMMU's page size across all architectures and in the
interest of a stop-gap fix to this functional issue, default the NVMe
device page size to 4K, with the intent of adding such an API and
implementation across all architectures in the next merge window.
With the functionally equivalent v3 of this patch, our hardware test
exerciser survives when using 32-bit DMA; without the patch, the kernel
will BUG within a few minutes.

WARNING: drivers/pci/host/built-in.o(.data+0x7780): Section mismatch in reference from the variable hisi_pcie_driver to the function .init.text:hisi_pcie_probe()
If the probe for this device gets deferred past the point where __init

Commit 77b0a099674a ("cdc-ncm: use common parser") added a dangerous
new trust in the CDC functional descriptors presented by the device,
unconditionally assuming that any device handled by the driver has
a CDC Union descriptor.
This descriptor is required by the NCM and MBIM specs, but crashing
on non-compliant devices is still unacceptable. Not only will that
allow malicious devices to crash the kernel, but in this case it is
also well known that there are non-compliant real devices on the
market - as shown by the comment accompanying the IAD workaround
in the same function.
The Sierra Wireless EM7305 is an example of such device, having
a CDC header and a CDC MBIM descriptor but no CDC Union:
Interface Descriptor:
bLength 9
bDescriptorType 4
bInterfaceNumber 12
bAlternateSetting 0
bNumEndpoints 1
bInterfaceClass 2 Communications
bInterfaceSubClass 14
bInterfaceProtocol 0
iInterface 0
CDC Header:
bcdCDC 1.10
CDC MBIM:
bcdMBIMVersion 1.00
wMaxControlMessage 4096
bNumberFilters 16
bMaxFilterSize 128
wMaxSegmentSize 4064
bmNetworkCapabilities 0x20
8-byte ntb input size
Endpoint Descriptor:
..
The conversion to a common parser also left the local cdc_union
variable untouched. This caused the IAD workaround code to be applied
to all devices with an IAD descriptor, which was never intended. Finish
the conversion by testing for hdr.usb_cdc_union_desc instead.

Pull block layer fixes from Jens Axboe:
"A round of fixes/updates for the current series.
This looks a little bigger than it is, but that's mainly because we
pushed the lightnvm enabled null_blk change out of the merge window so
it could be updated a bit. The rest of the volume is also mostly
lightnvm. In particular:
- Lightnvm. Various fixes, additions, updates from Matias and
Javier, as well as from Wenwei Tao.
- NVMe:
- Fix for potential arithmetic overflow from Keith.
- Also from Keith, ensure that we reap pending completions from
a completion queue before deleting it. Fixes kernel crashes
when resetting a device with IO pending.
- Various little lightnvm related tweaks from Matias.
- Fixup flushes to go through the IO scheduler, for the cases where a
flush is not required. Fixes a case in CFQ where we would be
idling and not see this request, hence not break the idling. From
Jan Kara.
- Use list_{first,prev,next} in elevator.c for cleaner code. From
Gelian Tang.
- Fix for a warning trigger on btrfs and raid on single queue blk-mq
devices, where we would flush plug callbacks with preemption
disabled. From me.
- A mac partition validation fix from Kees Cook.
- Two merge fixes from Ming, marked stable. A third part is adding a
new warning so we'll notice this quicker in the future, if we screw
up the accounting.
- Cleanup of thread name/creation in mtip32xx from Rasmus Villemoes"
* 'for-linus' of git://git.kernel.dk/linux-block: (32 commits)
blk-merge: warn if figured out segment number is bigger than nr_phys_segments
blk-merge: fix blk_bio_segment_split
block: fix segment split
blk-mq: fix calling unplug callbacks with preempt disabled
mac: validate mac_partition is within sector
mtip32xx: use formatting capability of kthread_create_on_node
NVMe: reap completion entries when deleting queue
lightnvm: add free and bad lun info to show luns
lightnvm: keep track of block counts
nvme: lightnvm: use admin queues for admin cmds
lightnvm: missing free on init error
lightnvm: wrong return value and redundant free
null_blk: do not del gendisk with lightnvm
null_blk: use device addressing mode
null_blk: use ppa_cache pool
NVMe: Fix possible arithmetic overflow for max segments
blk-flush: Queue through IO scheduler when flush not required
null_blk: register as a LightNVM device
elevator: use list_{first,prev,next}_entry
lightnvm: cleanup queue before target removal

If enable Mediatek 8173 SoC, it should also enable power domain
driver. Otherwise access clk subsystem register will fail.

On some cards it takes a relatively long time for the change

The drm_fbdev_cma_restore_mode() function tests whether its argument
is NULL and then returns immediately.
Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.

The crtc child device driver shouldn't modify the of_node of its platform
device in the probe function. Instead, since the previous patch, the IPU
core driver sets the of_node when the platform device is created.
Drop the now unused custom imx_drm_get_port_by_id function.

The crtc child device driver shouldn't have to modify the of_node of its
platform device in the probe function. Instead, let the IPU core driver
set the of_node when the platform device is created.
Also reorder the client_reg array so the elements are in port id order
(CSIs first, then DIs).

panel
Similarly to commit 5e501ed7253b3 ("drm/imx: imx-ldb: allow to determine
bus format from the connected panel"), if a panel is connected to the ldb
output port via the of_graph bindings, the data mapping is determined from
the display_info.bus_format field provided by the panel instead of from the
optional interface_pix_fmt device tree property.

TI's mux and divider clock drivers do not require locking and they do
not initialize internal spinlocks. This code was occasionally
copy-posted from generic mux/divider drivers. So remove it.

Commit fcb26ec5b18d ("broadcom: move all PHY_ID's to header")
updated broadcom_tbl to use PHY_IDs, but incorrectly replaced 0x0143bca0
with PHY_ID_BCM5482 (making a duplicate entry, and completely omitting
the original). Fix that.

The IMX6Q/IMX6DL SoC's have a 2-bit temperature grade stored in OTP which
is valid for all IMX6 SoC's (despite the fact that the IMXSDLRM and
IMXSXRM do not document this - this has been proven via tests as well as
verified by Freescale FAE).
Instead of assuming a fixed 85C for passive cooling threshold and 105C for
critical use the thermal grade for these configurations.
We will set the critical to maxT - 5C and passive to maxT - 10C.

----
v3:
- rebase against linux-soc-thermal.git
- added ack's from Shawn and Jon
v2:
- remove check for IMX6Q and update comments: The OTP values have been tested
on IMX6SOLO, IMX6DUALLITE, and IMX6SX and Freescale FAE has shared data with
me that the OTP settings are the same and that the reference manuals will
reflect this in their next updates.
- set critical to max - 5C
- set passive to max - 10C
- display max temp in info
- do not allow passive to be set above critical
