After the last user was removed, remove this PCI core function. It's very
unlikely that we'll see a new device requiring io space access, even though
memory space access is supported.

A few lines earlier pcim_enable_device() is called, which includes the
functionality of pci_enable_device_io(). Therefore we can safely remove the
call to pci_enable_device_io().

The custom EC address space handler in the WMI driver was only needed
because the EC driver did not install its address space handler for
EC operation regions beyond the EC device scope in the ACPI namespace.
That has just changed, so the custom EC address handler is not needed
any more and it can be removed.

It is reported that _DSM evaluation fails in ucsi_acpi_dsm() on Lenovo
IdeaPad Pro 5 due to a missing address space handler for the EC address
space:
ACPI Error: No handler for Region [ECSI] (000000007b8176ee) [EmbeddedControl] (20230628/evregion-130)
This happens because if there is no ECDT, the EC driver only registers
the EC address space handler for operation regions defined in the EC
device scope of the ACPI namespace while the operation region being
accessed by the _DSM in question is located beyond that scope.
To address this, modify the ACPI EC driver to install the EC address
space handler at the root of the ACPI namespace for the first EC that
can be found regardless of whether or not an ECDT is present.
Note that this change is consistent with some examples in the ACPI
specification in which EC operation regions located outside the EC
device scope are used (for example, see Section 9.17.15 in ACPI 6.5),
so the current behavior of the EC driver is arguably questionable.

The -t option has an optional argument.
The usual case is for a short option to be specified without an '='
and for the long version to be specified with an '='
Various forms of this do not work as expected.
For example:
rtla timerlat hist -T50 -tfile.txt
will result in a truncated file name of "ile.txt"
Another example is that the long form without the '=' will result in the
default file name instead of the requested file name.
This patch properly parses the optional argument with and without '='
and with and without spaces for the short form.
This patch was also tested using -t and --trace without providing a file
name both as the last requested option and with a following long and
short option.
For example:
rtla timerlat hist -T50 -t -u
rtla timerlat hist -T50 --trace -u
This fix is applied to both timerlat top and hist
and to osnoise top and hist.
Here is the full testing for rtla timerlat hist.
Before applying the patch
rtla timerlat hist -T50 -t=file.txt
Works as expected, "file.txt"
rtla timerlat hist -T50 -tfile.txt
Truncated file name "ile.txt"
rtla timerlat hist -T50 -t file.txt
Default file name instead of file.txt
rtla timerlat hist -T50 --trace=file.txt
Truncated file name "ile.txt"
rtla timerlat hist -T50 --trace file.txt
Default file name "timerlat_trace.txt" instead of "file.txt"
After applying the patch:
rtla timerlat hist -T50 -t=file.txt
Works as expected, "file.txt"
rtla timerlat hist -T50 -tfile.txt
Works as expected, "file.txt"
rtla timerlat hist -T50 -t file.txt
Works as expected, "file.txt"
rtla timerlat hist -T50 --trace=file.txt
Works as expected, "file.txt"
rtla timerlat hist -T50 --trace file.txt
Works as expected, "file.txt"
In addition the following tests were performed to make sure that
the default file name worked as expected including with trailing
options.
rtla timerlat hist -T50 -t
Works as expected "timerlat_trace.txt"
rtla timerlat hist -T50 --trace
Works as expected "timerlat_trace.txt"
rtla timerlat hist -T50 -t -u
Works as expected "timerlat_trace.txt"
rtla timerlat hist -T50 --trace -u
Works as expected "timerlat_trace.txt"

Add the option allow the users to set a different buffer size for the
trace. For example, in large systems, the user might be interested on
reducing the trace buffer to avoid large tracing files.
The buffer size is specified in kB, and it is only affecting
the tracing instance.
The function trace_set_buffer_size() appears on libtracefs v1.6,
so increase the minimum required version on Makefile.config.

The qrtr protocol core logic and the qrtr nameservice are combined into
a single module. Neither the core logic or nameservice provide much
functionality by themselves; combining the two into a single module also
prevents any possible issues that may stem from client modules loading
inbetween qrtr and the ns.
Creating a socket takes two references to the module that owns the
socket protocol. Since the ns needs to create the control socket, this
creates a scenario where there are always two references to the qrtr
module. This prevents the execution of 'rmmod' for qrtr.
To resolve this, forcefully put the module refcount for the socket
opened by the nameservice.

A debugfs directory entry is create early during probe(). This entry is
not removed on error path leading to some "already present" issues in
case of EPROBE_DEFER.
Create this entry later in the probe() code to avoid the need to change
many 'return' in 'goto' and add the removal in the already present error
path.

Since commit c98d2ecae08f ("s390/mm: Uncouple physical vs virtual address
spaces") the kernel image and module area are within the same 4GB area.
This eliminates the need of a custom insn slot allocator for kprobes within
the kernel image, since standard module_alloc() allocated pages are
sufficient for PC relative instructions with a signed 32 bit offset.

With the mentioned commit (see the fixes tag) on every AP bus scan an
uevent "AP bus change bindings complete" is emitted. Furthermore if an AP
device switched from one driver to another, for example by manipulating the
apmask, there was never a "bindings complete" uevent generated.
The "bindings complete" event should be sent once when all AP devices have
been bound to device drivers and again if unbind/bind actions take place
and finally all AP devices are bound again. Therefore implement this.

occured when /sys/bus/ap/a[pq]mask was updated with a relative mask value
(like +0x10-0x12,+60,-90) with one of the numeric values exceeding INT_MAX.
The fix is simple: use unsigned long values for the internal variables. The
correct checks are already in place in the function but a simple int for
the internal variables was used with the possibility to overflow.

Allocate cleared blocks in the bias range when the DRM
buddy's clear avail is zero. This will validate the bias
range allocation in scenarios like system boot when no
cleared blocks are available and exercise the fallback
path too. The resulting blocks should always be dirty.

Problem statement: During the system boot time, an application request
for the bulk volume of cleared range bias memory when the clear_avail
is zero, we dont fallback into normal allocation method as we had an
unnecessary clear_avail check which prevents the fallback method leads
to fb allocation failure following system goes into unresponsive state.
Solution: Remove the unnecessary clear_avail check in the range bias
allocation function.

topology IDs
Save the highest core and package id when parsing topology to
allocate enough memory when get_rapl_counters() is called with a core or
a package id as a domain.
Note that RAPL domains are per-package on Intel, but per-core on AMD.
Thus, the RAPL code effectively runs in different modes on those two
product lines.

New machines have multiple uncore frequencies per package,
visible in /sys/devices/system/cpu/intel_uncore_frequency/uncore##/
turbostat now samples these frequencies each measurement interval.
For each package, turbostat now prints "UMHzX.Y" columns,
where X = domain_id, and Y = fabric_cluster_id.
The system summary for each UMHzX.Y column is the average value
for across all of the packages in the system.

Pull workqueue updates from Tejun Heo:
- Work items can now be disabled and enabled, and cancel_work_sync()
and disable_work() can be called form atomic contexts for BH work
items.
This closes feature gap with tasklet and should allow converting all
existing tasklet users to BH workqueues.
- Improve pool sharing for unbound workqueues with strict affinity.
- Misc changes including doc updates, improved debug annotations and
cleanups.
