The framer codec interracts with a framer.
It allows to use some of the framer timeslots as audio channels to
transport audio data over the framer E1/T1/J1 lines.
It also reports line carrier detection events through the ALSA jack
detection feature.

A framer can be connected to the QMC HDLC.
If present, this framer is the interface between the TDM used by the QMC
HDLC and the E1/T1 line.
The QMC HDLC can use this framer to get information about the line and
configure the line.
Add an optional framer property to reference the framer itself.

The main change is to move secondary TLB invalidation mmu notifier
callbacks into the architecture specific TLB flushing functions. This
makes secondary TLB invalidation mostly match CPU invalidation while
still allowing efficient range based invalidations based on the
existing TLB batching code.
The ARM SMMU has a specific command for invalidating the TLB for an
entire ASID. Currently this is used for the IO_PGTABLE API but not for
ATS when called from the MMU notifier.
The current implementation of notifiers does not attempt to invalidate
such a large address range, instead walking each
The comment in mmu_interval_read_begin() refers to a function that
doesn't exist and uses the wrong call-back name. The op for mmu
interval notifiers is mmu_interval_notifier_ops->invalidate() so fix

The invalidate_range() is going to become an architecture specific mmu
notifier used to keep the TLB of secondary MMUs such as an IOMMU in
sync with the CPU page tables. Currently it is called from separate
code paths to the main CPU TLB invalidations. This can lead to a
secondary TLB not getting i
Secondary TLBs are now invalidated from the architecture specific TLB
invalidation functions. Therefore there is no need to explicitly
notify or invalidate as part of the range end functions. This means we
can remove mmu_notifier_invalidate_range_end_only() and some of the
ptep_*_notify() functions
There are two main use cases for mmu notifiers. One is by KVM which
uses mmu_notifier_invalidate_range_start()/end() to manage a software
TLB.
The other is to manage hardware TLBs which need to use the
invalidate_range() callback because HW can establish new TLB entries
at any time. Hence using st
