For 64bit kernel without HIGHMEM, high_memory is the virtual address of
the highest physical address in the system. But __va(get_num_physpages()
<< PAGE_SHIFT) is not what we want for high_memory because there may be
holes in the physical address space. On the other hand, max_low_pfn is
calculated from memblock_end_of_DRAM(), which is exactly corresponding
to the highest physical address, so use it for high_memory calculation.

As timbgpio_irq_enable()/timbgpio_irq_disable() callback could be
executed under irq context, it could introduce double locks on
&tgpio->lock if it preempts other execution units requiring
the same locks.

timbgpio_gpio_set()
--> timbgpio_update_bit()
--> spin_lock(&tgpio->lock)
<interrupt>
   --> timbgpio_irq_disable()
   --> spin_lock_irqsave(&tgpio->lock)

This flaw was found by an experimental static analysis tool I am
developing for irq-related deadlock.

To prevent the potential deadlock, the patch uses spin_lock_irqsave()
on &tgpio->lock inside timbgpio_gpio_set() to prevent the possible
deadlock scenario.

Create buffers with cache coherency on the CPU side (write-back) while
disabling snooping on the VPU side. These buffers require an explicit
cache flush after each CPU-side modification.

Configuring pages as write-combined may introduce significant delays,
potentially taking hundreds of milliseconds for 64 MB buffers.

Added internal DRM_IVPU_BO_NOSNOOP mask which disables snooping on the
VPU side. Allocate FW runtime memory buffer (64 MB) as cached with
snooping-disabled.

This fixes random long FW loading times and boot params memory
corruption on warmboot (due to missed wmb).

Unmasking global interrupts will re-trigger MSI for any pending interrupts.

FREQ_CHANGE interrupt is triggered on D0I2 entry which will cause
KMD to check VPU interrupt sources by reading VPUIP registers.
Access to those registers will toggle necessary clocks and trigger
another FREQ_CHANGE interrupt possibly ending in an infinite loop.

We need to wait for the CLOCK_RESOURCE_OWN_ACK bit to be set
after configuring the workpoint. This step ensures that the VPU
microcontroller clock is actively toggling and ready for operation.

Previously, we relied solely on the READY bit in the VPU_STATUS
register, which indicated the completion of the workpoint download.
However, this approach was insufficient, as the READY bit could be set
while the device was still running on a sideband clock until the PLL
locked. To guarantee that the PLL is locked and the device is running on
the main clock source, we now wait for the CLOCK_RESOURCE_OWN_ACK before
proceeding with the remainder of the power-up sequence.

Pull workqueue fixes from Tejun Heo:

 - Remove double allocation of wq_update_pod_attrs_buf

 - Fix missing allocation of pwq_release_worker when
   wq_cpu_intensive_thresh_us is set to a custom value

  workqueue: Fix missed pwq_release_worker creation in wq_cpu_intensive_thresh_init()
  workqueue: Removed double allocation of wq_update_pod_attrs_buf

Ideally the busyness worker should take a gt pm wakeref because the
worker only needs to be active while gt is awake. However, the gt_park
path cancels the worker synchronously and this complicates the flow if
the worker is also running at the same time. The cancel waits for the
worker and when the worker releases the wakeref, that would call gt_park
and would lead to a deadlock.

The resolution is to take the global pm wakeref if runtime pm is already
active. If not, we don't need to update the busyness stats as the stats
would already be updated when the gt was parked.

Note:
- We do not requeue the worker if we cannot take a reference to runtime
  pm since intel_guc_busyness_unpark would requeue the worker in the
  resume path.

- If the gt was parked longer than time taken for GT timestamp to roll
  over, we ignore those rollovers since we don't care about tracking the
  exact GT time. We only care about roll overs when the gt is active and
  running workloads.

- There is a window of time between gt_park and runtime suspend, where
  the worker may run. This is acceptable since the worker will not find
  any new data to update busyness.

- Use runtime pm in the worker
- Put runtime pm after enabling the worker

The folio conversion changed the behaviour of shmem_sg_alloc_table() to
put the entire length of the last folio into the sg list, even if the sg
list should have been shorter.  gen8_ggtt_insert_entries() relied on the
list being the right length and would overrun the end of the page tables.
Other functions may also have been affected.

Clamp the length of the last entry in the sg list to be the expected
length.

Nathan reported that he was seeing the new warning in
setattr_copy_mgtime pop when starting podman containers. Overlayfs is
trying to set the atime and mtime via notify_change without also
setting the ctime.

POSIX states that when the atime and mtime are updated via utimes() that
we must also update the ctime to the current time. The situation with
overlayfs copy-up is analogies, so add ATTR_CTIME to the bitmask.
notify_change will fill in the value.

During ntfs_fill_super() some resources are allocated that we need to
cleanup in ->put_super() such as additional inodes. When
ntfs_fill_super() fails these resources need to be cleaned up as well.
