When tick values are large, the multiplication by NSEC_PER_SEC is larger
than 64 bits and results in bad conversions.
The issue is seen in PMU busyness counters that look like they have
wrapped around due to bad conversion. i915 PMU implementation returns
monotonically increasing counters. If a count is lesser than previous
one, it will only return the larger value until the smaller value
catches up. The user will see this as zero delta between two
measurements even though the engines are busy.
Fix it by using mul_u64_u32_div()

The comment referenced the flag name incorrectly as 'I915_EXEC_NORELOC'
(missing underscore). This patch corrects the spelling in the comment
only; there is no functional change.

shmem_pwrite() currently checks for short writes before negative error
codes, which can overwrite real errors (e.g., -EFBIG) with -EIO.
Reorder the checks to return negative errors first, then handle short

Without O_LARGEFILE, file->f_op->write_iter calls
generic_write_check_limits(), which enforces a 2GB (MAX_NON_LFS) limit,
causing -EFBIG on large writes.
In shmem_pwrite(), this error is later masked as -EIO due to the error
handling order, leading to igt failures like gen9_exec_parse(bb-large).
Set O_LARGEFILE in __create_shmem() to prevent -EFBIG on large writes.

Condition guards are found to be redundant, as the call flow is properly
managed now, as also observed in the Exynos5433 DECON driver. Since
state checking is no longer necessary, remove it.
This also fixes an issue which prevented decon_commit() from
decon_atomic_enable() due to an incorrect state change setting.

Similar to FIMD and Exynos5433's DECON, the Exynos7 DECON hardware:
- May optionally require an IOMMU to initialize a display region.
- Outputs image data to another block, say an MIC or a DSI master.
If an IOMMU is present, it may also require to access the reserved
framebuffer region.

Presently, all devices refer to clock names from a single array. The
only controlling parameter is the number of clocks (num_clks field of
samsung_dsim_driver_data) which uses the first n clocks of that array.
As new devices are added, this approach turns out to be cumbersome.
Separate the clock names in individual arrays required by each variant,
in a struct clk_bulk_data. Add a pointer field to the driver data struct
which points to their respective clock names, and rework the clock usage
code to use the clk_bulk_* API instead.

The buffer size of sysfs is fixed at PAGE_SIZE, and the page offset
of the buf parameter of sysfs_emit_at() must be 0, there is no need
to manually manage the buf pointer offset.
Fixes: 711d41ab4a0e ("usb: core: Use sysfs_emit_at() when showing dynamic IDs")
