Initialize the eb.vma array with values of 0 when the eb structure is
first set up. In particular, this sets the eb->vma[i].vma pointers to
NULL, simplifying cleanup and getting rid of the bug described below.
During the execution of eb_lookup_vmas(), the eb->vma array is
successively filled up with struct eb_vma objects. This process includes
calling eb_add_vma(), which might fail; however, even in the event of
failure, eb->vma[i].vma is set for the currently processed buffer.
If eb_add_vma() fails, eb_lookup_vmas() returns with an error, which
prompts a call to eb_release_vmas() to clean up the mess. Since
eb_lookup_vmas() might fail during processing any (possibly not first)
buffer, eb_release_vmas() checks whether a buffer's vma is NULL to know
at what point did the lookup function fail.
In eb_lookup_vmas(), eb->vma[i].vma is set to NULL if either the helper
function eb_lookup_vma() or eb_validate_vma() fails. eb->vma[i+1].vma is
set to NULL in case i915_gem_object_userptr_submit_init() fails; the
current one needs to be cleaned up by eb_release_vmas() at this point,
so the next one is set. If eb_add_vma() fails, neither the current nor
the next vma is set to NULL, which is a source of a NULL deref bug
described in the issue linked in the Closes tag.
When entering eb_lookup_vmas(), the vma pointers are set to the slab
poison value, instead of NULL. This doesn't matter for the actual
lookup, since it gets overwritten anyway, however the eb_release_vmas()
function only recognizes NULL as the stopping value, hence the pointers
are being set to NULL as they go in case of intermediate failure. This
patch changes the approach to filling them all with NULL at the start
instead, rather than handling that manually during failure.

Currently, the mtk_hdmi_ddc_v2 driver sends a i2c message by calling
the mtk_ddc_wr_one function for each byte of the payload to setup
SI2C_CTRL and DDC_CTRL registers, and perform a sequential write
transfer of one byte at a time to the target device. This leads to
incorrect transfers as the target address (at least) is also sent each
time.
So, rename mtk_ddc_wr_one function to mtk_ddcm_write_hdmi to match the
read function name (mtk_ddcm_read_hdmi) and modify its behaviour to
send all payload data in a single sequential write transfer by filling
the transfer fifo first then starting the transfer with a size equal to
the payload size and not one anymore.

During a read or write transfer, the mtk_hdmi_ddc_v2 driver polls the
DDC_I2C_IN_PROG bit of HPD_DDC_STATUS register to check if the transfer
completes but do no particular action if a timeout is reached. It could
lead the next transfer attempts to fail because the faulty transfer was
not aborted. So, add in both low level read and write functions a abort
action by writing the DDC_CTRL register with the ABORT_XFER command
value.

When building with -Wincompatible-function-pointer-types-strict, a
warning designed to catch kernel control flow integrity (kCFI) issues at
build time, there is an instance in the new HDMI v2 drm/mediatek code:
drivers/gpu/drm/mediatek/mtk_hdmi_v2.c:1331:31: error: incompatible function pointer types initializing 'enum drm_mode_status (*)(const struct drm_bridge *, const struct drm_display_mode *, unsigned long long)' with an expression of type 'int (const struct drm_bridge *, const struct drm_display_mode *, unsigned long long)' [-Werror,-Wincompatible-function-pointer-types-strict]
1331 | .hdmi_tmds_char_rate_valid = mtk_hdmi_v2_hdmi_tmds_char_rate_valid,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
While 'int' and 'enum drm_mode_status' are ABI compatible, hence no
regular warning from -Wincompatible-function-pointer-types, the mismatch
will trigger a kCFI violation when mtk_hdmi_v2_tmds_char_rate_valid() is
called indirectly.
Update the return type of mtk_hdmi_v2_tmds_char_rate_valid() to be 'enum
drm_mode_status' to clear up the warning and kCFI violation.

The platform_get_irq() function returns negative error codes on failure
and positive non-zero IRQ numbers on success. It never returns NULL. Fix
the error checking to look for negatives, and change "hdmi->irq" from
unsigned int to just int.

The refill_buf function uses snprintf to append to a fixed-size buffer.
snprintf returns the length that would have been written, which can
exceed the remaining buffer size. If this happens, ptr advances beyond
the buffer and rem becomes negative. In the 2nd iteration, rem is
treated as a large unsigned integer, causing snprintf to write oob.
While this behavior is technically mitigated by num_perfcntrs being
locked at 5, it's still unsafe if num_perfcntrs were ever to change/a
second source was added.

This reverts commit 5978864e34b66bdae4d7613834c03dd5d0a0c891.
At least on Hamoa based devices, there are IOMMU faults:
arm-smmu 15000000.iommu: Unhandled context fault: fsr=0x402, iova=0x00000000, fsynr=0x3d0023, cbfrsynra=0x1c00, cb=13
arm-smmu 15000000.iommu: FSR = 00000402 [Format=2 TF], SID=0x1c00
arm-smmu 15000000.iommu: FSYNR0 = 003d0023 [S1CBNDX=61 PNU PLVL=3]
While on some of these devices, there are also all sorts of artifacts on eDP.
Reverting this fixes these issues.

In situations where no system memory is migrated to devmem, and in
upcoming patches where another GPU is performing the migration to
the newly allocated devmem buffer, there is nothing to ensure any
ongoing clear to the devmem allocation or async eviction from the
devmem allocation is complete.
Address that by passing a struct dma_fence down to the copy
functions, and ensure it is waited for before migration is marked
complete.
v3:
- New patch.
v4:
- Update the logic used for determining when to wait for the
pre_migrate_fence.
- Update the logic used for determining when to warn for the
pre_migrate_fence since the scheduler fences apparently
can signal out-of-order.
v5:
- Fix a UAF (CI)
- Remove references to source P2P migration (Himal)
- Put the pre_migrate_fence after migration.
v6:
- Pipeline the pre_migrate_fence dependency (Matt Brost)
