The code to map the physical memory retrieved by memmap currently
allocates an array of pages to cover the physical memory and then calls
vmap() to map it to a virtual address. Instead of using this temporary
array of struct page descriptors, simply use vmap_page_range() that can
directly map the contiguous physical memory to a virtual address.

The reserve_mem kernel command line option may pass back a physical
address, but the memory is still part of the normal memory just like
using memblock_alloc() would be. This means that the physical memory
returned by the reserve_mem command line option can be converted directly
to virtual memory by simply using phys_to_virt().
When freeing the buffer there's no need to call vunmap() anymore as the
memory allocated by reserve_mem is freed by the call to
reserve_mem_release_by_name().
Because the persistent ring buffer can also be allocated via the memmap
option, which *is* different than normal memory as it cannot be added back
to the buddy system, it must be treated differently. It still needs to be
virtually mapped to have access to it. It also can not be freed nor can it
ever be memory mapped to user space.
Create a new trace_array flag called TRACE_ARRAY_FL_MEMMAP which gets set
if the buffer is created by the memmap option, and this will prevent the
buffer from being memory mapped by user space.
Also increment the ref count for memmap'ed buffers so that they can never
be freed.

Enforce that the address and the size of the memory used by the persistent
ring buffer is page aligned. Also update the documentation to reflect this

All the fastpaths that need device usage don't need the sector totals or
fragmentation, just bucket counts.
Split bch_dev_usage up into two different versions, the normal one with
just bucket counts.
This is also a stack usage improvement, since we have a bch_dev_usage on
the stack in the allocation path.

We now have separate per device io_refs for read and write access.
This fixes a device removal bug where the discard workers were still
running while we're removing alloc info for that device.
It's also a bit of hardening; we no longer allow writes to devices that

Commit ac91052f0ae5 ("tracing: tprobe-events: Fix leakage of module
refcount") moved try_module_get() from __find_tracepoint_module_cb()
to find_tracepoint() caller, but that introduced a possible UAF
because the module can be unloaded before try_module_get(). In this
case, the module object should be freed too. Thus, try_module_get()
does not only fail but may access to the freed object.
To avoid that, try_module_get() in __find_tracepoint_module_cb()
again.

Since register_fprobe() does not get the module reference count while
registering fgraph filter, if the target functions (symbols) are in
modules, those modules can be unloaded when registering fprobe to
fgraph.
To avoid this issue, get the reference counter of module for each
symbol, and put it after register the fprobe.

Kernel cross-compilation with BUILDTIME_MCOUNT_SORT produces zeroed
mcount values if the build-host endianness does not match the ELF
file endianness.
The mcount values array is converted from ELF file
endianness to build-host endianness during initialization in
fill_relocs()/fill_addrs(). Avoid extra conversion of these values during
weak-function zeroing; otherwise, they do not match nm-parsed addresses
and all mcount values are zeroed out.

The trace event verifier checks the formats of trace events to make sure
that they do not point at memory that is not in the trace event itself or
in data that will never be freed. If an event references data that was
allocated when the event triggered and that same data is freed before the
event is read, then the kernel can crash by reading freed memory.
The verifier runs at boot up (or module load) and scans the print formats
of the events and checks their arguments to make sure that dereferenced
pointers are safe. If the format uses "%*p.." the verifier will ignore it,
and that could be dangerous. Cover this case as well.
Also add to the sample code a use case of "%*pbl".

When the kernel contains a large number of functions that can be traced,
the loop in ftrace_graph_set_hash() may take a lot of time to execute.
This may trigger the softlockup watchdog.
Add cond_resched() within the loop to allow the kernel to remain
responsive even when processing a large number of functions.
This matches the cond_resched() that is used in other locations of the
code that iterates over all functions that can be traced.

The option PROBE_EVENTS_BTF_ARGS enables the functions
btf_find_func_proto() and btf_get_func_param() which are used by the
function argument tracing code. The option FUNCTION_TRACE_ARGS was
dependent on the same configs that PROBE_EVENTS_BTF_ARGS was dependent on,
but it was also dependent on PROBE_EVENTS_BTF_ARGS. In fact, if
PROBE_EVENTS_BTF_ARGS is supported then FUNCTION_TRACE_ARGS is supported.
Just make FUNCTION_TRACE_ARGS depend on PROBE_EVENTS_BTF_ARGS.

The lookup table forces the use of the "pinctrl-bcm2835" GPIO chip
provider and essentially assumes that there is going to be such a
provider, and if not, we will fail to set-up the SPI device.
While this is true on Raspberry Pi based systems (2835/36/37, 2711,
2712), this is not true on 7712/77122 Broadcom STB systems which use the
SPI driver, but not the GPIO driver.
There used to be an early check:
chip = gpiochip_find("pinctrl-bcm2835", chip_match_name);
if (!chip)
return 0;
which would accomplish that nicely, bring something similar back by
checking for the compatible strings matched by the pinctrl-bcm2835.c
driver, if there is no Device Tree node matching those compatible
strings, then we won't find any GPIO provider registered by the
"pinctrl-bcm2835" driver.

After ieee80211_do_stop() SKB from vif's txq could still be processed.
Indeed another concurrent vif schedule_and_wake_txq call could cause
those packets to be dequeued (see ieee80211_handle_wake_tx_queue())
without checking the sdata current state.
Because vif.drv_priv is now cleared in this function, this could lead to
driver crash.
For example in ath12k, ahvif is store in vif.drv_priv. Thus if
ath12k_mac_op_tx() is called after ieee80211_do_stop(), ahvif->ah can be
NULL, leading the ath12k_warn(ahvif->ah,...) call in this function to
trigger the NULL deref below.

The ieee80211 skb control block key (set when skb was queued) could have
been removed before ieee80211_tx_dequeue() call. ieee80211_tx_dequeue()
already called ieee80211_tx_h_select_key() to get the current key, but
the latter do not update the key in skb control block in case it is
NULL. Because some drivers actually use this key in their TX callbacks
(e.g. ath1{1,2}k_mac_op_tx()) this could lead to the use after free

There is a possible race between removing a cgroup diectory that is
a partition root and the creation of a new partition. The partition
to be removed can be dying but still online, it doesn't not currently
participate in checking for exclusive CPUs conflict, but the exclusive
CPUs are still there in subpartitions_cpus and isolated_cpus. These
two cpumasks are global states that affect the operation of cpuset
partitions. The exclusive CPUs in dying cpusets will only be removed
when cpuset_css_offline() function is called after an RCU delay.
As a result, it is possible that a new partition can be created with
exclusive CPUs that overlap with those of a dying one. When that dying
partition is finally offlined, it removes those overlapping exclusive
CPUs from subpartitions_cpus and maybe isolated_cpus resulting in an
incorrect CPU configuration.
This bug was found when a warning was triggered in
remote_partition_disable() during testing because the subpartitions_cpus
mask was empty.
One possible way to fix this is to iterate the dying cpusets as well and
avoid using the exclusive CPUs in those dying cpusets. However, this
can still cause random partition creation failures or other anomalies
due to racing. A better way to fix this race is to reset the partition
state at the moment when a cpuset is being killed.
Introduce a new css_killed() CSS function pointer and call it, if
defined, before setting CSS_DYING flag in kill_css(). Also update the
css_is_dying() helper to use the CSS_DYING flag introduced by commit
33c35aa48178 ("cgroup: Prevent kill_css() from being called more than
once") for proper synchronization.
Add a new cpuset_css_killed() function to reset the partition state of
a valid partition root if it is being killed.

Pull iommufd updates from Jason Gunthorpe:
"Two significant new items:
- Allow reporting IOMMU HW events to userspace when the events are
clearly linked to a device.
This is linked to the VIOMMU object and is intended to be used by a
VMM to forward HW events to the virtual machine as part of
emulating a vIOMMU. ARM SMMUv3 is the first driver to use this
mechanism. Like the existing fault events the data is delivered
through a simple FD returning event records on read().
- PASID support in VFIO.
The "Process Address Space ID" is a PCI feature that allows the
device to tag all PCI DMA operations with an ID. The IOMMU will
then use the ID to select a unique translation for those DMAs. This
is part of Intel's vIOMMU support as VT-D HW requires the
hypervisor to manage each PASID entry.
The support is generic so any VFIO user could attach any
translation to a PASID, and the support should work on ARM SMMUv3
as well. AMD requires additional driver work.
Some minor updates, along with fixes:
- Prevent using nested parents with fault's, no driver support today
- Put a single "cookie_type" value in the iommu_domain to indicate
what owns the various opaque owner fields"
