Add apq/ipq8064 errata workaround where the sec_src clock gating needs to
be disabled during switching. krait-cc compatible is not enough to
handle this and limit this workaround to apq/ipq8064. We check machine
compatible to handle this.

Since IOMMU groups are mandatory for drivers to support, it stands to
reason that any device which has been successfully added to a group
must be on a bus supported by that IOMMU driver, and therefore a domain
viable for any device in the group must be viable for all devices in
the group. This already has to be the case for the IOMMU API's internal
default domain, for instance. Thus even if the group contains devices on
different buses, that can only mean that the IOMMU driver actually
supports such an odd topology, and so without loss of generality we can
expect the bus type of any device in a group to be suitable for IOMMU
API calls.
Furthermore, scrutiny reveals a lack of protection for the bus being
removed while vfio_iommu_type1_attach_group() is using it; the reference
that VFIO holds on the iommu_group ensures that data remains valid, but
does not prevent the group's membership changing underfoot.
We can address both concerns by recycling vfio_bus_type() into some
superficially similar logic to indirect the IOMMU API calls themselves.
Each call is thus protected from races by the IOMMU group's own locking,
and we no longer need to hold group-derived pointers beyond that scope.
It also gives us an easy path for the IOMMU API's migration of bus-based
interfaces to device-based, of which we can already take the first step
with device_iommu_capable(). As with domains, any capability must in
practice be consistent for devices in a given group - and after all it's
still the same capability which was expected to be consistent across an
entire bus! - so there's no need for any complicated validation.

Using two different types of workoads, it was observed that
guc_update_engine_gt_clks was being called too frequently and/or
causing a CPU-to-lmem bandwidth hit over PCIE. Details on
the workloads and numbers are in the notes below.
Background: At the moment, guc_update_engine_gt_clks can be invoked
via one of 3 ways. #1 and #2 are infrequent under normal operating
conditions:
1.When a predefined "ping_delay" timer expires so that GuC-
busyness can sample the GTPM clock counter to ensure it
doesn't miss a wrap-around of the 32-bits of the HW counter.
(The ping_delay is calculated based on 1/8th the time taken
for the counter go from 0x0 to 0xffffffff based on the
GT frequency. This comes to about once every 28 seconds at a
GT frequency of 19.2Mhz).
2.In preparation for a gt reset.
3.In response to __gt_park events (as the gt power management
puts the gt into a lower power state when there is no work
being done).
Root-cause: For both the workloads described farther below, it was
observed that when user space calls IOCTLs that unparks the
gt momentarily and repeats such calls many times in quick succession,
it triggers calling guc_update_engine_gt_clks as many times. However,
the primary purpose of guc_update_engine_gt_clks is to ensure we don't
miss the wraparound while the counter is ticking. Thus, the solution
is to ensure we skip that check if gt_park is calling this function
earlier than necessary.
Solution: Snapshot jiffies when we do actually update the busyness
stats. Then get the new jiffies every time intel_guc_busyness_park
is called and bail if we are being called too soon. Use half of the
ping_delay as a safe threshold.
NOTE1: Workload1: IGTs' gem_create was modified to create a file handle,
allocate memory with sizes that range from a min of 4K to the max supported
(in power of two step-sizes). Its maps, modifies and reads back the
memory. Allocations and modification is repeated until total memory
allocation reaches the max. Then the file handle is closed. With this
workload, guc_update_engine_gt_clks was called over 188 thousand times
in the span of 15 seconds while this test ran three times. With this patch,
the number of calls reduced to 14.
NOTE2: Workload2: 30 transcode sessions are created in quick succession.
While these sessions are created, pcm-iio tool was used to measure I/O
read operation bandwidth consumption sampled at 100 milisecond intervals
over the course of 20 seconds. The total bandwidth consumed over 20 seconds
without this patch was measured at average at 311KBps per sample. With this
patch, the number went down to about 175Kbps which is about a 43% savings.

This reverts commit 1e98d8c52ed5dfbaf273c4423c636525c2ce59e7.
The problem with this patch is that it makes i915_request to hold a
reference to intel_context, which in turn holds a reference on the VM.
This strong back referencing can lead to reference loops which leads
to resource leak.
An example is the upcoming VM_BIND work which requires VM to hold
a reference to some shared VM specific BO. But this BO's dma-resv
fences holds reference to the i915_request thus leading to reference
loop.

EXPORT_SYMBOL and __init is a bad combination because the .init.text
section is freed up after the initialization. Hence, modules cannot
use symbols annotated __init. The access to a freed symbol may end up
with kernel panic.
modpost used to detect it, but it had been broken for a decade.
Commit 28438794aba4 ("modpost: fix section mismatch check for exported
init/exit sections") fixed it so modpost started to warn it again, then
this showed up:
MODPOST vmlinux.symvers
WARNING: modpost: vmlinux.o(___ksymtab_gpl+tick_nohz_full_setup+0x0): Section mismatch in reference from the variable __ksymtab_tick_nohz_full_setup to the function .init.text:tick_nohz_full_setup()
The symbol tick_nohz_full_setup is exported and annotated __init
Fix this by removing the __init annotation of tick_nohz_full_setup or drop the export.
Drop the export because tick_nohz_full_setup() is only called from the
built-in code in kernel/sched/isolation.c.

When br_netfilter module is loaded, skbs may be diverted to the
ipv4/ipv6 hooks, just like as if we were routing.
Unfortunately, bridge filter hooks with priority 0 may be skipped
in this case.
Example:
1. an nftables bridge ruleset is loaded, with a prerouting
hook that has priority 0.
2. interface is added to the bridge.
3. no tcp packet is ever seen by the bridge prerouting hook.
4. flush the ruleset
5. load the bridge ruleset again.
6. tcp packets are processed as expected.
After 1) the only registered hook is the bridge prerouting hook, but its
not called yet because the bridge hasn't been brought up yet.
After 2), hook order is:
0 br_nf_pre_routing // br_netfilter internal hook
0 chain bridge f prerouting // nftables bridge ruleset
The packet is diverted to br_nf_pre_routing.
If call-iptables is off, the nftables bridge ruleset is called as expected.
But if its enabled, br_nf_hook_thresh() will skip it because it assumes
that all 0-priority hooks had been called previously in bridge context.
To avoid this, check for the br_nf_pre_routing hook itself, we need to
resume directly after it, even if this hook has a priority of 0.
Unfortunately, this still results in different packet flow.
With this fix, the eval order after in 3) is:
1. br_nf_pre_routing
2. ip(6)tables (if enabled)
3. nftables bridge
but after 5 its the much saner:
1. nftables bridge
2. br_nf_pre_routing
3. ip(6)tables (if enabled)
Unfortunately I don't see a solution here:
It would be possible to move br_nf_pre_routing to a higher priority
so that it will be called later in the pipeline, but this also impacts
ebtables evaluation order, and would still result in this very ordering
problem for all nftables-bridge hooks with the same priority as the
br_nf_pre_routing one.
Searching back through the git history I don't think this has
ever behaved in any other way, hence, no fixes-tag.

When verdict is NF_STOLEN, the skb might have been freed.
When tracing is enabled, this can result in a use-after-free:
1. access to skb->nf_trace
2. access to skb->mark
3. computation of trace id
4. dump of packet payload
To avoid 1, keep a cached copy of skb->nf_trace in the
trace state struct.
Refresh this copy whenever verdict is != STOLEN.
Avoid 2 by skipping skb->mark access if verdict is STOLEN.
3 is avoided by precomputing the trace id.
Only dump the packet when verdict is not "STOLEN".

nft_rhash_update() might fail for two reasons:
- Element already exists in the hashtable.
- Another packet won race to insert an entry in the hashtable.
In both cases, new() has already bumped the counter via atomic_add_unless(),
therefore, decrement the set element counter.
Fixes: 22fe54d5fefc ("netfilter: nf_tables: add support for dynamic set updates")

XE_LPD_CURSOR_OFFSETS is a duplicate of TGL_CURSOR_OFFSETS.
Just use the latter.

Stop hand rolling _MMIO_TRANS2() and just use the real thing.
Note that this register isn't even used atm, hence why this
builds despite the _PIPE2() macro not actually existing.

The other similar macros have the _MMIO prefix, so give
it also to _CURSOR2.

Using a signed type for the register offsets doesn't really

The use of 'extern' in function prototypes has been disrecommended in
the kernel coding style for several years now, remove them from all vfio
related files so contributors no longer need to decide between style and
consistency.

Eliminate the PIPECONF RMWs from .comit_commit() so
that we can finally declare the whole vblank evade part
(and the noarm() part) of the pipe commit free of register
reads. Or at least I hope that's the last read...
Only the i9xx/ilk codepaths need this for now, but let's
add the same thing for hsw+ just in case we want to start
calling that during fastsets at some point (eg. to change
dithering settings/etc.).
Should open up the way to start experimenting with
different DSB usage approaches for pipe commits.
