Extend migrate_vma_collect_pmd() to handle partially mapped large
folios that require splitting before migration can proceed.
During PTE walk in the collection phase, if a large folio is only
partially mapped in the migration range, it must be split to ensure
the folio is correctly migrated.

Add a new helper function that allows MEI client drivers
to query the maximum transmission unit (MTU) for a connected
MEI client.
This is useful for clients that need to transmit large payloads,
such as firmware blobs, allowing them to determine the maximum
message size t
Hi Marek,
Thanks for the patch.

Use negative error code -EINVAL instead of positive EINVAL in the default
case of svm_ioctl() to conform to Linux kernel error code conventions.

The IEC958 subframe format SNDRV_PCM_FMTBIT_IEC958_SUBFRAME_LE are used
in HDMI and DisplayPort to describe the audio stream, but hardware device
may need to reorder the IEC958 bits for internal transmission, so need
these standard bits definitions for IEC958 subframe format.

All interleaved RGB formats use only 1 plane and MDP_FETCH_LINEAR.
Specify num_planes and fetch_mode directly in the macro and remove
unused parameters.
