ASoC: qcom: Fix building APQ8016 machine driver without SOUNDWIRE
Older Qualcomm platforms like APQ8016 do not have hardware support for
SoundWire, so kernel configurations made specifically for those platforms
will usually not have CONFIG_SOUNDWIRE enabled.

Unfortunately commit 8d89cf6ff2 ("ASoC: qcom: cleanup and fix
dependency of QCOM_COMMON") breaks those kernel configurations, because
SOUNDWIRE is now a required dependency for SND_SOC_QCOM_COMMON (and in
turn also SND_SOC_APQ8016_SBC). Trying to migrate such a kernel config
silently disables SND_SOC_APQ8016_SBC and breaks audio functionality.

The soundwire helpers in common.c are only used by two of the Qualcomm
audio machine drivers, so building and requiring CONFIG_SOUNDWIRE for
all platforms is unnecessary.

There is no need to stuff all common code into a single module. Fix the
issue by moving the soundwire helpers to a separate SND_SOC_QCOM_SDW
module/option that is selected only by the machine drivers that make
use of them. This also allows reverting the imply/depends changes from
the previous fix because both SM8250 and SC8280XP already depend on
SOUNDWIRE, so the soundwire helpers will be only built if SOUNDWIRE
is really enabled.

80f8be7af0 tomoyo: Omit use of bin2c
bin2c was, as its name implies, introduced to convert a binary file to
C code.

However, I did not see any good reason ever for using this tool because
using the .incbin directive is much faster, and often results in simpler
code.

Most of the uses of bin2c have been killed, for example:

  - 13610aa908 ("kernel/configs: use .incbin directive to embed config_data.gz")
  - 4c0f032d49 ("s390/purgatory: Omit use of bin2c")

security/tomoyo/Makefile has even less reason for using bin2c because
the policy files are text data. So, sed is enough for converting them
to C string literals, and what is nicer, generates human-readable
builtin-policy.h.

This is the last user of bin2c. After this commit lands, bin2c will be
removed.

75507a3198 i2c: designware: Fix unbalanced suspended flag
Ensure that i2c_mark_adapter_suspended() is always balanced by a call to
i2c_mark_adapter_resumed().

dw_i2c_plat_resume() must always be called, so that
i2c_mark_adapter_resumed() is called. This is not compatible with
DPM_FLAG_MAY_SKIP_RESUME, so remove the flag.

Since the controller is always resumed on system resume the
dw_i2c_plat_complete() callback is redundant and has been removed.

The unbalanced suspended flag was introduced by commit c57813b8b2
("i2c: designware: Lock the adapter while setting the suspended flag")

Before that commit, the system and runtime PM used the same functions. The
DPM_FLAG_MAY_SKIP_RESUME was used to skip the system resume if the driver
had been in runtime-suspend. If system resume was skipped, the suspended
flag would be cleared by the next runtime resume. The check of the
suspended flag was _after_ the call to pm_runtime_get_sync() in
i2c_dw_xfer(). So either a system resume or a runtime resume would clear
the flag before it was checked.

Having introduced the unbalanced suspended flag with that commit, a further
commit 80704a84a9
("i2c: designware: Use the i2c_mark_adapter_suspended/resumed() helpers")

changed from using a local suspended flag to using the
i2c_mark_adapter_suspended/resumed() functions. These use a flag that is
checked by I2C core code before issuing the transfer to the bus driver, so
there was no opportunity for the bus driver to runtime resume itself before
the flag check.

Mark DDR clocks as critical for AT91 devices. These clocks are enabled
by bootloader when initializing DDR and needs to stay enabled. Up to
this patch the DDR clocks were requested from drivers/memory/atmel-sdramc.c
which does only clock request and enable. There is no need to have

c8c37bc514 i2c: designware: use casting of u64 in clock multiplication to avoid overflow
In functions i2c_dw_scl_lcnt() and i2c_dw_scl_hcnt() may have overflow
by depending on the values of the given parameters including the ic_clk.
For example in our use case where ic_clk is larger than one million,
multiplication of ic_clk * 4700 will result in 32 bit overflow.

Add cast of u64 to the calculation to avoid multiplication overflow, and
use the corresponding define for divide.

38aaf921e9 perf/x86: Add Meteor Lake support
From PMU's perspective, Meteor Lake is similar to Alder Lake. Both are
hybrid platforms, with e-core and p-core.

The key differences include:
- The e-core supports 2 PDIST GP counters (GP0 & GP1)
- New MSRs for the Module Snoop Response Events on the e-core.
- New Data Source fields are introduced for the e-core.
- There are 8 GP counters for the e-core.
- The load latency AUX event is not required for the p-core anymore.
- Retire Latency (Support in a separate patch) for both cores.

Since most of the code in the intel_pmu_init() should be the same as
Alder Lake, to avoid code duplication, share the path with Alder Lake.

Add new specific functions of extra_regs, and get_event_constraints
to support the OCR events, Module Snoop Response Events and 2 PDIST
GP counters on e-core.

Add new MTL specific mem_attrs which drops the load latency AUX event.

The Data Source field is extended to 4:0, which can contains max 32
sources.

The Retire Latency is implemented with a separate patch.

9a5418bc48 sched/core: Use kfree_rcu() in do_set_cpus_allowed()
Commit 851a723e45 ("sched: Always clear user_cpus_ptr in
do_set_cpus_allowed()") may call kfree() if user_cpus_ptr was previously
set. Unfortunately, some of the callers of do_set_cpus_allowed()
may have pi_lock held when calling it. So the following splats may be
printed especially when running with a PREEMPT_RT kernel:

   WARNING: possible circular locking dependency detected
   BUG: sleeping function called from invalid context

To avoid these problems, kfree_rcu() is used instead. An internal
cpumask_rcuhead union is created for the sole purpose of facilitating
the use of kfree_rcu() to free the cpumask.

Since user_cpus_ptr is not being used in non-SMP configs, the newly
introduced alloc_user_cpus_ptr() helper will return NULL in this case
and sched_setaffinity() is modified to handle this special case.

87ca4f9efb sched/core: Fix use-after-free bug in dup_user_cpus_ptr()
Since commit 07ec77a1d4 ("sched: Allow task CPU affinity to be
restricted on asymmetric systems"), the setting and clearing of
user_cpus_ptr are done under pi_lock for arm64 architecture. However,
dup_user_cpus_ptr() accesses user_cpus_ptr without any lock
protection. Since sched_setaffinity() can be invoked from another
process, the process being modified may be undergoing fork() at
the same time.  When racing with the clearing of user_cpus_ptr in
__set_cpus_allowed_ptr_locked(), it can lead to user-after-free and
possibly double-free in arm64 kernel.

Commit 8f9ea86fdf ("sched: Always preserve the user requested
cpumask") fixes this problem as user_cpus_ptr, once set, will never
be cleared in a task's lifetime. However, this bug was re-introduced
in commit 851a723e45 ("sched: Always clear user_cpus_ptr in
do_set_cpus_allowed()") which allows the clearing of user_cpus_ptr in
do_set_cpus_allowed(). This time, it will affect all arches.

Fix this bug by always clearing the user_cpus_ptr of the newly
cloned/forked task before the copying process starts and check the
user_cpus_ptr state of the source task under pi_lock.

Note to stable, this patch won't be applicable to stable releases.
Just copy the new dup_user_cpus_ptr() function over.

45e966fcca KVM: x86: Do not return host topology information from KVM_GET_SUPPORTED_CPUID
Passing the host topology to the guest is almost certainly wrong
and will confuse the scheduler.  In addition, several fields of
these CPUID leaves vary on each processor; it is simply impossible to
return the right values from KVM_GET_SUPPORTED_CPUID in such a way that
they can be passed to KVM_SET_CPUID2.

The values that will most likely prevent confusion are all zeroes.
Userspace will have to override it anyway if it wishes to present a
specific topology to the guest.

74905e3de8 KVM: nSVM: clarify recalc_intercepts() wrt CR8
The mysterious comment "We only want the cr8 intercept bits of L1"
dates back to basically the introduction of nested SVM, back when
the handling of "less typical" hypervisors was very haphazard.
With the development of kvm-unit-tests for interrupt handling,
the same code grew another vmcb_clr_intercept for the interrupt
window (VINTR) vmexit, this time with a comment that is at least
decent.

It turns out however that the same comment applies to the CR8 write
intercept, which is also a "recheck if an interrupt should be
injected" intercept.  The CR8 read intercept instead has not
been used by KVM for 14 years (commit 649d68643e, "KVM: SVM:
sync TPR value to V_TPR field in the VMCB"), so do not bother
clearing it and let one comment describe both CR8 write and VINTR
handling.

On Xilinx ZynqMP platform, both OCM Controller driver(zynqmp_edac) and DDR
Memory Controller driver(synopsys_edac) co-exist which means both can be loaded
at a time. This scenario is tested on Xilinx ZynqMP platform.

96b87cbdeb fs/ext2: Replace kmap_atomic() with kmap_local_page()
kmap_atomic() is deprecated in favor of kmap_local_page(). Therefore,
replace kmap_atomic() with kmap_local_page().

kmap_atomic() is implemented like a kmap_local_page() which also disables
page-faults and preemption (the latter only for !PREEMPT_RT kernels).

However, the code within the mapping and un-mapping in ext2_make_empty()
does not depend on the above-mentioned side effects.

Therefore, a mere replacement of the old API with the new one is all it
is required (i.e., there is no need to explicitly add any calls to
pagefault_disable() and/or preempt_disable()).
