Size of pages are held by struct ib_umem in page_size field.
It is better to store it as an exponent, because page size by nature
is always power-of-two and used as a factor, divisor or ilog2's argument.
The conversion of page_size to be page_shift allows to have portable
code and avoid following error while compiling on ARM:
ERROR: "__aeabi_uldivmod" [drivers/infiniband/core/ib_core.ko] undefined!

cab_queue can now get bigger than u8, since in TVQM we will support
512 queues..
Support it by maintaining internal mapping between the actual number
and mac80211 queue (IWL_MVM_DQA_GCAST_QUEUE).
For pre-a000 the internal queue will be the same as the mac80211
queue.

Wifi mcc (mobile country code) update is forbidden while associated.
Currently, FW prevents these updates and the driver is unaware to
this logic. From now on, the FW sends every wifi mcc update to the
driver. The driver in his turn needs to decide whether to
ignore it or not, depends on the association state.

The 'num_sge' variable is verfied to be smaller than the 'sge_count'
variable; however, since both are user-controlled it's possible to cause
an integer overflow for the kmalloc multiply on 32-bit platforms
(num_sge and sge_count are both defined u32). By crafting an input that
causes a smaller-than-expected allocation it's possible to write
controlled data out-of-bounds.

hns_roce_v1_cq_set_ci() calls roce_set_bit() on an uninitialized field,
which will then change only a few of its bits, causing a warning with
the latest gcc:
infiniband/hw/hns/hns_roce_hw_v1.c: In function 'hns_roce_v1_cq_set_ci':
infiniband/hw/hns/hns_roce_hw_v1.c:1854:23: error: 'doorbell[1]' is used uninitialized in this function [-Werror=uninitialized]
roce_set_bit(doorbell[1], ROCEE_DB_OTHERS_H_ROCEE_DB_OTH_HW_SYNS_S, 1);
The code is actually correct since we always set all bits of the
port_vlan field, but gcc correctly points out that the first
access does contain uninitialized data.
This initializes the field to zero first before setting the
individual bits.

This adds two methods to spk_synth struct: send_xchar and tiocmset, and
creates serial implementation for each of them. It takes existing code
in apollo, audptr and spkout which already fits the behaviour of
send_xchar and tiocmset. In follow-up patches there will be TTY-based
implementations of these methods. Then migrating the synths to TTY will
include repointing these methods to their TTY implementations
Rest of the changes simply make use of serial implementation of these two
functions.

Kthreads are currently implemented as an infinite loop. Each
has its own variant of checks for terminating, freezing,
awakening. In many cases it is unclear to say in which state
it is and sometimes it is done a wrong way.
The plan is to convert kthreads into kthread_worker or workqueues
API. It allows to split the functionality into separate operations.
It helps to make a better structure. Also it defines a clean state
where no locks are taken, IRQs blocked, the kthread might sleep
or even be safely migrated.
The kthread worker API is useful when we want to have a dedicated
single thread for the work. It helps to make sure that it is
available when needed. Also it allows a better control, e.g.
define a scheduling priority.
This patch converts the frm_pool kthread into the kthread worker
API because I am not sure how busy the thread is. It is well
possible that it does not need a dedicated kthread and workqueues
would be perfectly fine. Well, the conversion between kthread
worker API and workqueues is pretty trivial.
The patch moves one iteration from the kthread into the work function.
It is queued only when there is a pending work. Therefore we do not
need to compare flush_ser and req_ser at the beginning. On the contrary,
the same work could be queued only once at a time. Therefore it has to
re-queue itself if some requests are pending.
Otherwise, wake_up_process() is replaced by queuing the work.
Important: The change is only compile tested. I did not find an easy
way how to check it in a real life.

This reverts commit 833415a3e781 ("cdc-wdm: fix "out-of-sync" due to
missing notifications")
There have been several reports of wdm_read returning unexpected EIO
errors with QMI devices using the qmi_wwan driver. The reporters
confirm that reverting prevents these errors. I have been unable to
reproduce the bug myself, and have no explanation to offer either. But
reverting is the safe choice here, given that the commit was an
attempt to work around a firmware problem. Living with a firmware
problem is still better than adding driver bugs.

lpfc was changing the private pointer that is set/maintained by
the nvme_fc transport. This caused two issues: a) the transport, on
teardown may erroneous attempt to free whatever address was set;
and b) lfpc uses any value set in lpfc_nvme_fcp_abort() and
assumes its a valid io request.
Correct issue by properly defining a context structure for lpfc.
Lpfc also updated to clear the private context structure on io
completion.
Since this bug caused scrutiny of the way lpfc moves local request
structures between lists, also cleaned up list_del()'s to
list_del_inits()'s.
This is a nvme-specific bug. The patch was cut against the
linux-block tree, for-4.12/block tree. It should be pulled in through
that tree.

Resetting a zone write pointer is equivalent to discarding sectors:
after a reset, the zone sectors will contain zeros (or the format
pattern). So there is no need for mutual exclusion between a zone reset

discard and write).

This patch adds hardware channel APIs support between
VF and PF for tunnelling configuration for the VFs.
According to that configuration VFs can run VXLAN/GENEVE/GRE
tunnels over it with tunnel features offloaded.
Using these APIs VF can also request for UDP ports configuration
to the PF, although PF and it's child VFs share the same port.

This patch configures UDP ports locally instead of
configuring them in deferred context which would be
helpful in synchronizing UDP ports configuration for VFs
which will be enabled in further patches.
