b) change the argument order to have the buffer as first argument
c) add a new argument telling the function if the message was

On Bay Trail and Cherry Trail devices we set the pm_disabled flag for I2C
busses which the OS shares with the PUNIT as these need special handling.
Until now we called dev_pm_syscore_device(dev, true) for I2C controllers
with this flag set to keep these I2C controllers always on.

After commit 12864ff8 ("ACPI / LPSS: Avoid PM quirks on suspend and
resume from hibernation"), this no longer works. This commit modifies
lpss_iosf_exit_d3_state() to only run if lpss_iosf_enter_d3_state() has ran
before it, so that it does not run on a resume from hibernate (or from S3).

On these systems the conditions for lpss_iosf_enter_d3_state() to run
never become true, so lpss_iosf_exit_d3_state() never gets called and
the 2 LPSS DMA controllers never get forced into D0 mode, instead they
are left in their default automatic power-on when needed mode.

The not forcing of D0 mode for the DMA controllers enables these systems
to properly enter S0ix modes, which is a good thing.

But after entering S0ix modes the I2C controller connected to the PMIC
no longer works, leading to e.g. broken battery monitoring.

The _PS3 method for this I2C controller looks like this:

            Method (_PS3, 0, NotSerialized)  // _PS3: Power State 3
            {
                If ((((PMID == 0x04) || (PMID == 0x05)) || (PMID == 0x06)))
                {
                    Return (Zero)
                }

                PSAT |= 0x03
                Local0 = PSAT /* \_SB_.I2C5.PSAT */
            }

Where PMID = 0x05, so we enter the Return (Zero) path on these systems.

So even if we were to not call dev_pm_syscore_device(dev, true) the
I2C controller will be left in D0 rather then be switched to D3.

Yet on other Bay and Cherry Trail devices S0ix is not entered unless *all*
I2C controllers are in D3 mode. This combined with the I2C controller no
longer working now that we reach S0ix states on these systems leads to me
believing that the PUNIT itself puts the I2C controller in D3 when all
other conditions for entering S0ix states are true.

Since now the I2C controller is put in D3 over a suspend/resume we must
re-initialize it afterwards and that does indeed fix it no longer working.

This commit implements this fix by:

1) Making the suspend_late callback a no-op if pm_disabled is set and
making the resume_early callback skip the clock re-enable (since it now was
not disabled) while still doing the necessary I2C controller re-init.

2) Removing the dev_pm_syscore_device(dev, true) call, so that the suspend
and resume callbacks are actually called. Normally this would cause the
ACPI pm code to call _PS3 putting the I2C controller in D3, wreaking havoc
since it is shared with the PUNIT, but in this special case the _PS3 method
is a no-op so we can safely allow a "fake" suspend / resume.

Commit 7ae81952cda ("i2c: i801: Allow ACPI SystemIO OpRegion to conflict
with PCI BAR") made it possible for AML code to access SMBus I/O ports
by installing custom SystemIO OpRegion handler and blocking i80i driver
access upon first AML read/write to this OpRegion.

However, while ThinkPad T560 does have SystemIO OpRegion declared under
the SMBus device, it does not access any of the SMBus registers:

    Device (SMBU)
    {
        ...

        OperationRegion (SMBP, PCI_Config, 0x50, 0x04)
        Field (SMBP, DWordAcc, NoLock, Preserve)
        {
            ,   5,
            TCOB,   11,
            Offset (0x04)
        }

        Name (TCBV, 0x00)
        Method (TCBS, 0, NotSerialized)
        {
            If ((TCBV == 0x00))
            {
            TCBV = (\_SB.PCI0.SMBU.TCOB << 0x05)
            }

            Return (TCBV) /* \_SB_.PCI0.SMBU.TCBV */
        }

        OperationRegion (TCBA, SystemIO, TCBS (), 0x10)
        Field (TCBA, ByteAcc, NoLock, Preserve)
        {
            Offset (0x04),
            ,   9,
            CPSC,   1
        }
    }

Problem with the current approach is that it blocks all I/O port access
and because this system has touchpad connected to the SMBus controller
after first AML access (happens during suspend/resume cycle) the
touchpad fails to work anymore.

Fix this so that we allow ACPI AML I/O port access if it does not touch
the region reserved for the SMBus.

The newly added code that emits ksymtab entries as pairs of 32-bit
relative references interacts poorly with the way powerpc lays out its
address space: when a module exports a per-CPU variable, the primary
module region covering the ksymtab entry -and thus the 32-bit relative
reference- is too far away from the actual per-CPU variable's base
address (to which the per-CPU offsets are applied to obtain the
respective address of each CPU's copy), resulting in corruption when the
module loader attempts to resolve symbol references of modules that are
loaded on top and link to the exported per-CPU symbol.

So let's disable this feature on powerpc.  Even though it implements
CONFIG_RELOCATABLE, it does not implement CONFIG_RANDOMIZE_BASE and so
KASLR kernels (which are the main target of the feature) do not exist on
powerpc anyway.

100 ms is not enough time for the LSPCON adapter on Intel NUC devices to
settle. This causes dropped display modes at boot or screen reconfiguration.
Empirical testing can reproduce the error up to a timeout of 190 ms. Basic
boot and stress testing at 200 ms has not (yet) failed.

Increase timeout to 400 ms to get some margin of error.

Changes from v1:
The initial suggestion of 1000 ms was lowered due to concerns about delaying

  nvme-pci: add a memory barrier to nvme_dbbuf_update_and_check_event

Like d88b6d04: "cdrom: information leak in cdrom_ioctl_media_changed()"

There is another cast from unsigned long to int which causes
a bounds check to fail with specially crafted input. The value is
then used as an index in the slot array in cdrom_slot_status().

Pull thermal fixes from Eduardo Valentin:
 "Minor fixes to OF thermal, qoriq, and rcar drivers"

* 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal:
  thermal: of-thermal: disable passive polling when thermal zone is disabled
  thermal: rcar_gen3_thermal: convert to SPDX identifiers
  thermal: rcar_thermal: convert to SPDX identifiers
  thermal: qoriq: Switch to SPDX identifier
  thermal: qoriq: Simplify the 'site' variable assignment
  thermal: qoriq: Use devm_thermal_zone_of_sensor_register()

Variable save_pud is being assigned but is never used hence it is
redundant and can be removed.

Cleans up clang warning:
variable 'save_pud' set but not used [-Wunused-but-set-variable]

Thanks to Christoph Hellwig for pointing out a cleaner way to do this,
as my approach was quite ugly.

As of commit fd1102f0 ("mm: mmu_notifier fix for tlb_end_vma"),
asm-generic/tlb.h now calls tlb_flush() from a static inline function,
so we need to make sure that it's declared before #including the
asm-generic header in the arch header.

I managed to miss one of Rob's code reviews on the mailing list
<http://lists.infradead.org/pipermail/linux-riscv/2018-August/001139.html>.
The patch has already been merged, so I'm submitting a fixup.

Sorry!

We use kzalloc to allocate the write_buf that we use for
i2c transfer on hdcp write. But it seems that we are forgetting
to free the memory that is not needed after i2c transfer is
completed.

The workaround was supposed to look at the plane destination
coordinates. Currently it's looking at some mixture of src
and dst coordinates that doesn't make sense. Fix it up.

Fix the VMC page fault when the running sequence is as below:
1.amdgpu_gem_create_ioctl
2.ttm_bo_swapout->amdgpu_vm_bo_invalidate, as not called
amdgpu_vm_bo_base_init, so won't called
list_add_tail(&base->bo_list, &bo->va). Even the bo was evicted,
it won't set the bo_base->moved.
3.drm_gem_open_ioctl->amdgpu_vm_bo_base_init, here only called
list_move_tail(&base->vm_status, &vm->evicted), but not set the
bo_base->moved.
4.amdgpu_vm_bo_map->amdgpu_vm_bo_insert_map, as the bo_base->moved is
not set true, the function amdgpu_vm_bo_insert_map will call
list_move(&bo_va->base.vm_status, &vm->moved)
5.amdgpu_cs_ioctl won't validate the swapout bo, as it is only in the
moved list, not in the evict list. So VMC page fault occurs.
