try_to_unmap_flush() used to open-code a rather x86-centric flush
sequence: local_flush_tlb() + flush_tlb_others(). Rearrange the
code so that the arch (only x86 for now) provides
arch_tlbbatch_add_mm() and arch_tlbbatch_flush() and the core code
calls those functions instead.
I'll want this for x86 because, to enable address space ids, I can't
support the flush_tlb_others() mode used by exising
try_to_unmap_flush() implementation with good performance. I can
support the new API fairly easily, though.
I imagine that other architectures may be in a similar position.
Architectures with strong remote flush primitives (arm64?) may have
even worse performance problems with flush_tlb_others() the way that
try_to_unmap_flush() uses it.

We have been a little loose with our intermediate VMCR representation
where we had a 'ctlr' field, but we failed to differentiate between the
GICv2 GICC_CTLR and ICC_CTLR_EL1 layouts, and therefore ended up mapping
the wrong bits into the individual fields of the ICH_VMCR_EL2 when
emulating a GICv2 on a GICv3 system.
Fix this by using explicit fields for the VMCR bits instead.

After reading the specs for the Faraday Technology FTDMAC020 found
in the Gemini platform, it becomes pretty evident that this is just
another PL08x derivative, and should be handled like such by simply
extending the existing PL08x driver to handle the quirks in this
hardware.
This patch makes memcpy work and has been tested on the Gemini and
also regression-tested on the Nomadik NHK15 using dmatest with
10 threads per channel without a hinch for hours.
I have not implemented slave DMA in those codepaths, because this
device (Gemini) does not use slave DMA, and it seems like devices
using FTDMAC020 for device DMA have a slightly different register
layout so some real hardware is needed to proceed with this. I
left some FIXME etc in the code for this.
I had to do some refactorings of some helper functions, but I have
not split those into separate patches because these refactorings
do not make much sense without the increased complexity of handling
the FTDMAC020.
The DMA test would hang the platform on me on the Gemini after a
few thousand iterations, however after turning of the caches the
problem immediately disappeared and I could run the DMA engine
with 10 threads pers physical channel for days in a row without
a crash. I think there is no problem with the DMA driver: instead
it is something fishy in the FA526 cache handling code that get
pretty heavily exercised by the DMA engine and we need to go and
fix that instead.

We cannot use bits from configuration registers as API between
platforms and driver like this, abstract it out to two enums
and mimic the stuff passed as device tree data.
This is done to make it possible for the driver to generate the
ccfg word on-the-fly so we can support more PL08x derivatives.

Some drivers - like i915 - may not support the system suspend direct
complete optimization due to differences in their runtime and system
suspend sequence. Add a flag that when set resumes the device before
calling the driver's system suspend handlers which effectively disables
the optimization.

Add new LSM hooks to allocate and free security contexts and check for
permission to access a PKey.
Allocate and free a security context when creating and destroying a QP.
This context is used for controlling access to PKeys.
When a request is made to modify a QP that changes the port, PKey index,
or alternate path, check that the QP has permission for the PKey in the
PKey table index on the subnet prefix of the port. If the QP is shared
make sure all handles to the QP also have access.
Store which port and PKey index a QP is using. After the reset to init
transition the user can modify the port, PKey index and alternate path
independently. So port and PKey settings changes can be a merge of the
previous settings and the new ones.
In order to maintain access control if there are PKey table or subnet
prefix change keep a list of all QPs are using each PKey index on
each port. If a change occurs all QPs using that device and port must
have access enforced for the new cache settings.
These changes add a transaction to the QP modify process. Association
with the old port and PKey index must be maintained if the modify fails,
and must be removed if it succeeds. Association with the new port and
PKey index must be established prior to the modify and removed if the
modify fails.
1. When a QP is modified to a particular Port, PKey index or alternate
path insert that QP into the appropriate lists.
2. Check permission to access the new settings.
3. If step 2 grants access attempt to modify the QP.
4a. If steps 2 and 3 succeed remove any prior associations.
4b. If ether fails remove the new setting associations.
If a PKey table or subnet prefix changes walk the list of QPs and
check that they have permission. If not send the QP to the error state
and raise a fatal error event. If it's a shared QP make sure all the
QPs that share the real_qp have permission as well. If the QP that
owns a security structure is denied access the security structure is
marked as such and the QP is added to an error_list. Once the moving
the QP to error is complete the security structure mark is cleared.
Maintaining the lists correctly turns QP destroy into a transaction.
The hardware driver for the device frees the ib_qp structure, so while
the destroy is in progress the ib_qp pointer in the ib_qp_security
struct is undefined. When the destroy process begins the ib_qp_security
structure is marked as destroying. This prevents any action from being
taken on the QP pointer. After the QP is destroyed successfully it
could still listed on an error_list wait for it to be processed by that
flow before cleaning up the structure.
If the destroy fails the QPs port and PKey settings are reinserted into
the appropriate lists, the destroying flag is cleared, and access control
is enforced, in case there were any cache changes during the destroy
flow.
To keep the security changes isolated a new file is used to hold security
related functionality.

Brought up by both Laurent and Andrzej when reviewing the new
->mode_valid hooks. Since mode_fixup is just a simpler version of the
much more generic atomic_check we can't really unify it with
mode_valid. Most drivers should probably switch their current
mode_fixup code to either the new mode_valid or the atomic_check
hooks, but e.g. that doesn't exist yet for bridges, and for CRTCs the
situation is a bit more complicated. Hence there's no clear
equivalence between mode_fixup and mode_valid, even if it looks like
that at first glance.

This adds a new callback to crtc, encoder and bridge helper functions
called mode_valid(). This callback shall be implemented if the
corresponding component has some sort of restriction in the modes
that can be displayed. A NULL callback implicates that the component
can display all the modes.
We also change the documentation so that the new and old callbacks
are correctly documented.
Only the callbacks were implemented to simplify review process,
following patches will make use of them.
Changes in v2 from Daniel:
- Update the warning about how modes aren't filtered in atomic_check -
the heleprs help out a lot more now.
- Consistenly roll out that warning, crtc/encoder's atomic_check
missed it.
- Sprinkle more links all over the place, so it's easier to see where
this stuff is used and how the differen hooks are related.
- Note that ->mode_valid is optional everywhere.
- Explain why the connector's mode_valid is special and does _not_ get
called in atomic_check.
v3: Document what can and cannot be checked in mode_valid a bit better
(Andrjez). Answer: Only allowed to look at the mode, nothing else.

Currently when firmware command gets stuck or it takes long time to
complete, the driver command will get timeout and the command slot is
freed and can be used for new commands, and if the firmware receive new
command on the old busy slot its behavior is unexpected and this could
be harmful.
To fix this when the driver command gets timeout we return failure,
but we don't free the command slot and we wait for the firmware to
explicitly respond to that command.
Once all the entries are busy we will stop processing new firmware
commands.

When I introduced ptracer_cred I failed to consider the weirdness of
fork where the task_struct copies the old value by default. This
winds up leaving ptracer_cred set even when a process forks and
the child process does not wind up being ptraced.
Because ptracer_cred is not set on non-ptraced processes whose
parents were ptraced this has broken the ability of the enlightenment
window manager to start setuid children.
Fix this by properly initializing ptracer_cred in ptrace_init_task
This must be done with a little bit of care to preserve the current value
of ptracer_cred when ptrace carries through fork. Re-reading the
ptracer_cred from the ptracing process at this point is inconsistent
with how PT_PTRACE_CAP has been maintained all of these years.

constant.
This patch simply add HMAC_IPAD_VALUE/HMAC_OPAD_VALUE defines in a new
include file "crypto/hmac.h" and use them in crypto/hmac.c

The DSA notifier events and info structure definitions are not meant for
DSA drivers and users, but only used internally by the DSA core files.
Move them from the public net/dsa.h file to the private dsa_priv.h file.
Also use this opportunity to turn the events into an anonymous enum,
because we don't care about the values, and this will prevent future
conflicts when adding (and sorting) new events.

min_vecs is the minimum amount of vectors needed to operate in MSI-X mode
which may just include the vectors that don't need affinity.
Disabling affinity settings causes the qla2xxx driver scsi_add_host() to fail
when blk_mq is enabled as the blk_mq_pci_map_queues() expects affinity masks
on each vector.

Pull networking fixes from David Miller:
"Mostly netfilter bug fixes in here, but we have some bits elsewhere as
well.
1) Don't do SNAT replies for non-NATed connections in IPVS, from
Julian Anastasov.
2) Don't delete conntrack helpers while they are still in use, from
Liping Zhang.
3) Fix zero padding in xtables's xt_data_to_user(), from Willem de
Bruijn.
4) Add proper RCU protection to nf_tables_dump_set() because we
cannot guarantee that we hold the NFNL_SUBSYS_NFTABLES lock. From
Liping Zhang.
5) Initialize rcv_mss in tcp_disconnect(), from Wei Wang.
6) smsc95xx devices can't handle IPV6 checksums fully, so don't
advertise support for offloading them. From Nisar Sayed.
7) Fix out-of-bounds access in __ip6_append_data(), from Eric
Dumazet.
8) Make atl2_probe() propagate the error code properly on failures,
from Alexey Khoroshilov.
9) arp_target[] in bond_check_params() is used uninitialized. This
got changes from a global static to a local variable, which is how
this mistake happened. Fix from Jarod Wilson.
10) Fix fallout from unnecessary NULL check removal in cls_matchall,
from Jiri Pirko. This is definitely brown paper bag territory..."
