tcp: re-add header prediction
Eric reported a performance regression caused by header prediction
removal.
We now call tcp_ack() much more frequently, for some workloads
this brings in enough cache line misses to become noticeable.
We could possibly still kill HP provided we find a different
way to suppress unneeded tcp_ack, but given we're late in
the cycle it seems preferable to revert.

We found at Google a significant regression caused by
45f119bf93 tcp: remove header prediction
In typical RPC (TCP_RR), when a TCP socket receives data, we now call
tcp_ack() while we used to not call it.
This touches enough cache lines to cause a slowdown.
so problem does not seem to be HP removal itself but the tcp_ack()
call. Therefore, it might be possible to remove HP after all, provided
one finds a way to elide tcp_ack for most cases.

Current implementation relies on L1 line length which might easily
be smaller than L2 line (which is usually the case BTW).
Imagine this typical case: L2 line is 128 bytes while L1 line is
64-bytes. Now we want to allocate small buffer and later use it for DMA
(consider IOC is not available).
kmalloc() allocates small KMALLOC_MIN_SIZE-sized, KMALLOC_MIN_SIZE-aligned
That way if buffer happens to be aligned to L1 line and not L2 line we'll be
flushing and invalidating extra portions of data from L2 which will cause
cache coherency issues.
And since KMALLOC_MIN_SIZE is bound to ARCH_DMA_MINALIGN the fix could
be simple - set ARCH_DMA_MINALIGN to the largest cache line we may ever
get. As of today neither L1 of ARC700 and ARC HS38 nor SLC might not be
longer than 128 bytes.

With the current IOMMU-API the hardware TLBs have to be
flushed in every iommu_ops->unmap() call-back.
For unmapping large amounts of address space, like it
happens when a KVM domain with assigned devices is
destroyed, this causes thousands of unnecessary TLB flushes
in the IOMMU hardware because the unmap call-back runs for
every unmapped physical page.
With the TLB Flush Interface and the new iommu_unmap_fast()
function introduced here the need to clean the hardware TLBs
is removed from the unmapping code-path. Users of
iommu_unmap_fast() have to explicitly call the TLB-Flush
functions to sync the page-table changes to the hardware.
Three functions for TLB-Flushes are introduced:
* iommu_flush_tlb_all() - Flushes all TLB entries
associated with that
domain. TLBs entries are
flushed when this function
returns.
* iommu_tlb_range_add() - This will add a given
range to the flush queue
for this domain.
* iommu_tlb_sync() - Flushes all queued ranges from
the hardware TLBs. Returns when
the flush is finished.
The semantic of this interface is intentionally similar to
the iommu_gather_ops from the io-pgtable code.

On some devices the USB Type-C port power (USB PD 2.0) negotiation is
done by a separate port-controller IC, while the current limit is
controlled through another (charger) IC.
It has been decided to model this by modelling the external Type-C
power brick (adapter/charger) as a power-supply class device which
supplies the charger-IC, with its voltage-now and current-max representing
the negotiated voltage and max current draw.
This commit adds support for this to the bq24190_charger driver by adding
an external_power_changed callback and calling
power_supply_set_input_current_limit_from_supplier from this callback.
This callback will only get called if the bq24190 has a parent-supply.
Note this replaces the functionality to get the current-limit from an
extcon device, which will be removed in a follow-up commit.

The new ioctl based infrastructure either commits or rollbacks
all objects of the method as one transaction. In order to do
that, we introduce a notion of dealing with a collection of
objects that are related to a specific method.
This also requires adding a notion of a method and attribute.
A method contains a hash of attributes, where each bucket
contains several attributes. The attributes are hashed according
to their namespace which resides in the four upper bits of the id.
For example, an object could be a CQ, which has an action of CREATE_CQ.
This action has multiple attributes. For example, the CQ's new handle
and the comp_channel. Each layer in this hierarchy - objects, methods
and attributes is split into namespaces. The basic example for that is
one namespace representing the default entities and another one
representing the driver specific entities.
When declaring these methods and attributes, we actually declare
their specifications. When a method is executed, we actually
allocates some space to hold auxiliary information. This auxiliary
information contains meta-data about the required objects, such
as pointers to their type information, pointers to the uobjects
themselves (if exist), etc.
The specification, along with the auxiliary information we allocated
and filled is given to the finalize_objects function.

The ioctl infrastructure treats all user-objects in the same manner.
It gets objects ids from the user-space and by using the object type
and type attributes mentioned in the object specification, it executes
this required method. Passing an object id from the user-space as
an attribute is carried out in three stages. The first is carried out
before the actual handler and the last is carried out afterwards.
The different supported operations are read, write, destroy and create.
In the first stage, the former three actions just fetches the object
from the repository (by using its id) and locks it. The last action
allocates a new uobject. Afterwards, the second stage is carried out
when the handler itself carries out the required modification of the
object. The last stage is carried out after the handler finishes and
commits the result. The former two operations just unlock the object.
Destroy calls the "free object" operation, taking into account the
object's type and releases the uobject as well. Creation just adds the
new uobject to the repository, making the object visible to the
application.
In order to abstract these details from the ioctl infrastructure
layer, we add uverbs_get_uobject_from_context and
uverbs_finalize_object functions which corresponds to the first
and last stages respectively.

Careful analysis shows that this flag is not needed.
The RESCUER flag is only needed when a make_request_fn might:
- allocate a bio from the bioset
- submit it with generic_make_request() or similar
- allocate another bio from the bioset
The second allocation can block until the first bio is processed, so
a rescuer is needed to ensure the first bio does get processed. With
a rescuer it will only get processed when the make_request_fn completes.
In drbd, allocations from drbd_io_bio_set happen from drbd_new_req()
or w_restart_disk_io() which is only called to handle
RESTART_FROZEN_DISK_IO.
In former is called precisely once from the make_request_fn.
The later is never called by within the make_request_fn.
So there cannot be two allocations in the same call to the
make_request_fn, so a rescuer is not needed.
Allocations from drbd_md_io_bio_set are used for IO to the bitmap and
the activity log. There are only accessed from worker threads and
workqueues, never directly from make_request_fn.
Again, the rescuer isn't needed.
