With gtt remapping in place we can use arbitrarily large
framebuffers. Let's bump the limits to 16kx16k on gen7+.
The limit was chosen to match the maximum 2D surface size
of the 3D engine.
With the remapping we could easily go higher than that for the
display engine. However the modesetting ddx will blindly assume
it can handle whatever is reported via kms. The oversized
buffer dimensions are not caught by glamor nor Mesa until
finally an assert will trip when genxml attempts to pack the
SURFACE_STATE. So we pick a safe limit to avoid the X server
from crashing (or potentially misbehaving if the genxml asserts
are compiled out).

With gtt remapping plugged in we can simply raise the stride
limit on gen4+. Let's just pick the limit to match the render
engine max stride (256KiB on gen7+, 128KiB on gen4+).
No remapping CCS because the virtual address of each page actually
matters due to the new hash mode
(WaCompressedResourceDisplayNewHashMode:skl,kbl etc.), and no
remapping on gen2/3 due extra complications from fence alignment
and gen2 2KiB GTT tile size. Also no real benefit since the
display engine limits already match the other limits.

The display engine stride limits are getting in our way. On SKL+
we are limited to 8k pixels, which is easily exceeded with three
4k displays. To overcome this limitation we can remap the pages
in the GTT to provide the display engine with a view of memory
with a smaller stride.
The code is mostly already there as We already play tricks with
the plane surface address and x/y offsets.
A few caveats apply:
* linear buffers need the fb stride to be page aligned, as
otherwise the remapped lines wouldn't start at the same
spot
* compressed buffers can't be remapped due to the new
ccs hash mode causing the virtual address of the pages
to affect the interpretation of the compressed data. IIRC
the old hash was limited to the low 12 bits so if we were
using that mode we could remap. As it stands we just refuse
to remapp with compressed fbs.
* no remapping gen2/3 as we'd need a fence for the remapped
vma, which we currently don't have. Need to deal with the
fence POT requirements, and do something about the gen2
gtt page size vs tile size difference
v2: Rebase due to is_ccs_modifier()
Fix up the skl+ stride_mult mess
memset() the gtt_view because otherwise we could leave
junk in plane[1] when going from 2 plane to 1 plane format
v3: intel_check_plane_stride() was split out
v4: Drop the aligned viewport stuff, it was meant for ccs which
can't be remapped anyway
v5: Introduce intel_plane_can_remap()
Reorder the code so that plane_state->view gets filled
even for invisible planes, otherwise we'd keep using
stale values and could explode during remapping. The new
logic never remaps invisible planes since we don't have
a viewport, and instead pins the full fb instead
v6: Fix plane src coord checks after remapping by moving
plane_state->base.src to the final plane x/y offsets.
Allow intel_plane_check_stride() to fail even with
remapping (can happen at least with a linear 64bpp
fb with a 4k plane and a suitably inconvenient src
coordinates).

This reverts commit 20bd1d026aacc5399464f8328f305985c493cde3.
This patch introduced regressions for devices that come online in
read-only state and subsequently switch to read-write.
Given how the partition code is currently implemented it is not
possible to persist the read-only flag across a device revalidate
call. This may need to get addressed in the future since it is common
for user applications to proactively call BLKRRPART.
Reverting this commit will re-introduce a regression where a
device-initiated revalidate event will cause the admin state to be
forgotten. A separate patch will address this issue.

When a HARDWARE_ERROR is triggered for ASC=0x3e, the existing code is only
considering the case where ASCQ=0x1.
According to the http://www.t10.org/lists/asc-num.htm#ASC_3E specification,
other values may occur like a timeout (ASCQ=0x2).
This patch prints an error message when a non-handled message is received.
This can help diagnose a possible misbehavior of the controller or a
missing implementation in the Linux kernel.
This patch keeps the exact same error handling but prints a message if an
ASCQ != 1 is reported.

So far, the drm_format_plane_height/width functions were operating on the
format's fourcc and was doing a lookup to retrieve the drm_format_info
structure and return the cpp.
However, this is inefficient since in most cases, we will have the
drm_format_info pointer already available so we shouldn't have to perform a
new lookup. Some drm_fourcc functions also already operate on the
drm_format_info pointer for that reason, so the API is quite inconsistent
there.
Let's follow the latter pattern and remove the extra lookup while being a
bit more consistent.
In order to be extra consistent, also rename that function to
drm_format_info_plane_cpp and to a static function in the header to match
the current policy. The parameters order have also be changed to match the
other functions prototype.

drm_format_horz_chroma_subsampling and drm_format_vert_chroma_subsampling
are basically a lookup in the drm_format_info table plus an access to the
hsub and vsub fields of the appropriate entry.
Most drivers are using this function while having access to the entry
already, which means that we will perform an unnecessary lookup. Removing
the call to these functions is therefore more efficient.
Some drivers will not have access to that entry in the function, but in
this case the overhead is minimal (we just have to call drm_format_info()
to perform the lookup) and we can even avoid multiple, inefficient lookups
in some places that need multiple fields from the drm_format_info
structure.
This is amplified by the fact that most of the time the callers will have
to retrieve both the vsub and hsub fields, meaning that they would perform
twice the lookup.

Pull RISC-V updates from Palmer Dabbelt:
"This contains an assortment of RISC-V related patches that I'd like to
target for the 5.2 merge window. Most of the patches are cleanups, but
there are a handful of user-visible changes:
- The nosmp and nr_cpus command-line arguments are now supported,
which work like normal.
- The SBI console no longer installs itself as a preferred console,
we rely on standard mechanisms (/chosen, command-line, hueristics)
instead.
- sfence_remove_sfence_vma{,_asid} now pass their arguments along to
the SBI call.
- Modules now support BUG().
- A missing sfence.vma during boot has been added. This bug only
manifests during boot.
- The arch/riscv support for SiFive's L2 cache controller has been
merged, which should un-block the EDAC framework work.
I've only tested this on QEMU again, as I didn't have time to get
things running on the Unleashed. The latest master from this morning
merges in cleanly and passes the tests as well"

Prevent reading unsupported slave address from SFP EEPROM by testing
Diagnostic Monitoring Type byte in EEPROM. Read only page zero of
EEPROM, in case this byte is zero.
If some SFP transceiver does not support Digital Optical Monitoring
(DOM), reading SFP EEPROM slave address 0x51 could return an error.
Availability of DOM support is verified by reading from zero page
Diagnostic Monitoring Type byte describing how diagnostic monitoring is
implemented by transceiver. If bit 6 of this byte is set, it indicates
that digital diagnostic monitoring has been implemented. Otherwise it is
not and transceiver could fail to reply to transaction for slave address
0x51 [1010001X (A2h)], which is used to access measurements page.
Such issue has been observed when reading cable MCP2M00-xxxx,
MCP7F00-xxxx, and few others.

QSFP modules temperature through MTMP register. Attempt to access this

Currently, the Kbuild core manipulates header search paths in a crazy
way [1].
To fix this mess, I want all Makefiles to add explicit $(srctree)/ to
the search paths in the srctree. Some Makefiles are already written in
that way, but not all. The goal of this work is to make the notation
consistent, and finally get rid of the gross hacks.
Having whitespaces after -I does not matter since commit 48f6e3cf5bc6

Flow destination comparison has an inaccuracy: code see no
difference between same vf ports, which belong to different pfs.
Example: If start ping from VF0 (PF1) to VF1 (PF1) and mirror
all traffic to VF0 (PF2), icmp reply to VF0 (PF1) and mirrored
flow to VF0 (PF2) would be determined as same destination. It lead
to creating flow handler with rule nodes, which not added to node
tree. When later driver try to delete this flow rules we got
kernel crash.
Add comparison of vhca_id field to avoid this.

in mlx5 this callback is disabled when CONFIG_MLX5_EN_RXNFC=n.

To avoid any ambiguity between vport index and vport number,
rename functions that had vport, to vport_num or vport_index appropriately.
vport_num is u16 hence change mlx5_eswitch_index_to_vport_num() return
type to u16.
vport_index is an int in vport array. Hence change input type of vport
index in mlx5_eswitch_index_to_vport_num() to int.
Correct multiple eswitch representor interfaces use type u16 of
rep->vport as type int vport_index.
Send vport FW commands with correct eswitch u16 vport_num instead
host int vport_index.

i2c_new_dummy is typically called from the probe function of the
driver for the primary i2c client. It requires calls to
i2c_unregister_device in the error path of the probe function and
in the remove function.
This can be simplified by introducing a device-managed version.
Note the changed error case return value type: i2c_new_dummy returns
NULL whilst devm_i2c_new_dummy_device returns an ERR_PTR.
