media: tc358746: select CONFIG_GENERIC_PHY
The tc358746 driver selects CONFIG_GENERIC_PHY_MIPI_DPHY and links to
that, but this fails when CONFIG_GENERIC_PHY is disabled, because Kbuild
then never enters the drivers/phy directory for building object files:
ERROR: modpost: "phy_mipi_dphy_get_default_config_for_hsclk" [drivers/media/i2c/tc358746.ko] undefined!
Add an explicit 'select GENERIC_PHY' here to ensure that the directory
is entered, and add another dependency on that symbol so make it
more obvious what is going on if another driver has the same problem,
as this will produce a Kconfig warning.

The compiler option '-fstrict-flex-arrays=3' has been enabled globally, and has been in -next for the entire devel cycle. This changes compiler diagnostics (though mainly just -Warray-bounds which is disabled) and potential UBSAN_BOUNDS and FORTIFY _warning_ coverage. In other words, there are no new restrictions, just potentially new warnings. Any new FORTIFY warnings we've seen have been fixed (usually in their respective subsystem trees).

workqueue: Ordered workqueue creation cleanups
For historical reasons, unbound workqueues with max concurrency limit of 1 are considered ordered, even though the concurrency limit hasn't been system-wide for a long time. This creates ambiguity around whether ordered execution is actually required for correctness, which was actually confusing for e.g. btrfs (btrfs updates are being routed through the btrfs tree). There aren't that many users in the tree which use the combination and there are pending improvements to unbound workqueue affinity handling which will make inadvertent use of ordered workqueue a bigger loss. This pull request clarifies the situation for most of them by updating the ones which require ordered execution to use alloc_ordered_workqueue(). There are some conversions being routed through subsystem-specific trees and likely a few stragglers. Once they're all converted, workqueue can trigger a warning on unbound + @max_active==1 usages and eventually drop the implicit ordered behavior. -----BEGIN PGP SIGNATURE----- iIQEABYIACwWIQTfIjM1kS57o3GsC/uxYfJx3gVYGQUCZJoKnA4cdGpAa2VybmVs Lm9yZwAKCRCxYfJx3gVYGc5SAQDOtjML7Cx9AYzbY5+nYc0wTebRRTXGeOu7A3Xy j50rVgEAjHgvHLIdmeYmVhCeHOSN4q7Wn5AOwaIqZalOhfLyKQk= =hs79 -----END PGP SIGNATURE----- Merge tag 'wq-for-6.5-cleanup-ordered' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq Pull ordered workqueue creation updates from Tejun Heo: "For historical reasons, unbound workqueues with max concurrency limit of 1 are considered ordered, even though the concurrency limit hasn't been system-wide for a long time.

s390 updates for 6.5 merge window
- Fix the style of protected key API driver source: use x-mas tree for all local variable declarations. - Rework protected key API driver to not use the struct pkey_protkey and pkey_clrkey anymore. Both structures have a fixed size buffer, but with the support of ECC protected key these buffers are not big enough. Use dynamic buffers internally and transparently for userspace. - Add support for a new 'non CCA clear key token' with ECC clear keys supported: ECC P256, ECC P384, ECC P521, ECC ED25519 and ECC ED448. This makes it possible to derive a protected key from the ECC clear key input via PKEY_KBLOB2PROTK3 ioctl, while currently the only way to derive is via PCKMO instruction. - The s390 PMU of PAI crypto and extension 1 NNPA counters use atomic_t for reference counting. Replace this with the proper data type refcount_t. - Select ARCH_SUPPORTS_INT128, but limit this to clang for now, since gcc generates inefficient code, which may lead to stack overflows. - Replace one-element array with flexible-array member in struct vfio_ccw_parent and refactor the rest of the code accordingly. Also, prefer struct_size() over sizeof() open- coded versions. - Introduce OS_INFO_FLAGS_ENTRY pointing to a flags field and OS_INFO_FLAG_REIPL_CLEAR flag that informs a dumper whether the system memory should be cleared or not once dumped. - Fix a hang when a user attempts to remove a VFIO-AP mediated device attached to a guest: add VFIO_DEVICE_GET_IRQ_INFO and VFIO_DEVICE_SET_IRQS IOCTLs and wire up the VFIO bus driver callback to request a release of the device. - Fix calculation for R_390_GOTENT relocations for modules. - Allow any user space process with CAP_PERFMON capability read and display the CPU Measurement facility counter sets. - Rework large statically-defined per-CPU cpu_cf_events data structure and replace it with dynamically allocated structures created when a perf_event_open() system call is invoked or /dev/hwctr device is accessed. -----BEGIN PGP SIGNATURE----- iI0EABYIADUWIQQrtrZiYVkVzKQcYivNdxKlNrRb8AUCZJsnCRccYWdvcmRlZXZA bGludXguaWJtLmNvbQAKCRDNdxKlNrRb8D+RAQCN5CYdql/X8kOMcs4jJvDHEZf8 5CHYfmT2SLNs+zWtLgD/f/C9XXv3El/0wMBvuWSZ+T1nw+imt2cz+FJ+Nor+UQg= =R7Dm -----END PGP SIGNATURE----- Merge tag 's390-6.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull s390 updates from Alexander Gordeev: - Fix the style of protected key API driver source: use x-mas tree for all local variable declarations - Rework protected key API driver to not use the struct pkey_protkey and pkey_clrkey anymore.

objtool changes for v6.5:
- Build footprint & performance improvements:
- Reduce memory usage with CONFIG_DEBUG_INFO=y
In the worst case of an allyesconfig+CONFIG_DEBUG_INFO=y kernel, DWARF
creates almost 200 million relocations, ballooning objtool's peak heap
usage to 53GB. These patches reduce that to 25GB.
On a distro-type kernel with kernel IBT enabled, they reduce objtool's
peak heap usage from 4.2GB to 2.8GB.
These changes also improve the runtime significantly.
- Debuggability improvements:
- Add the unwind_debug command-line option, for more extend unwinding
debugging output.
- Limit unreachable warnings to once per function
- Add verbose option for disassembling affected functions
- Include backtrace in verbose mode
- Detect missing __noreturn annotations
- Ignore exc_double_fault() __noreturn warnings
- Remove superfluous global_noreturns entries
- Move noreturn function list to separate file
- Add __kunit_abort() to noreturns
- Unwinder improvements:
- Allow stack operations in UNWIND_HINT_UNDEFINED regions
- drm/vmwgfx: Add unwind hints around RBP clobber
- Cleanups:
- Move the x86 entry thunk restore code into thunk functions
- x86/unwind/orc: Use swap() instead of open coding it
- Remove unnecessary/unused variables
- Fixes for modern stack canary handling

Merge tag 'objtool-core-2023-06-27' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull objtool updates from Ingo Molar:
"Build footprint & performance improvements:
- Reduce memory usage with CONFIG_DEBUG_INFO=y
In the worst case of an allyesconfig+CONFIG_DEBUG_INFO=y kernel,
DWARF creates almost 200 million relocations, ballooning objtool's
peak heap usage to 53GB. These patches reduce that to 25GB.
On a distro-type kernel with kernel IBT enabled, they reduce
objtool's peak heap usage from 4.2GB to 2.8GB.
These changes also improve the runtime significantly.
Debuggability improvements:
- Add the unwind_debug command-line option, for more extend unwinding
debugging output
- Limit unreachable warnings to once per function
- Add verbose option for disassembling affected functions
- Include backtrace in verbose mode
- Detect missing __noreturn annotations
- Ignore exc_double_fault() __noreturn warnings
- Remove superfluous global_noreturns entries
- Move noreturn function list to separate file
- Add __kunit_abort() to noreturns
Unwinder improvements:
- Allow stack operations in UNWIND_HINT_UNDEFINED regions
- drm/vmwgfx: Add unwind hints around RBP clobber
Cleanups:
- Move the x86 entry thunk restore code into thunk functions
- x86/unwind/orc: Use swap() instead of open coding it
- Remove unnecessary/unused variables
Fixes for modern stack canary handling"

Locking changes for v6.5:
- Introduce cmpxchg128() -- aka. the demise of cmpxchg_double().
The cmpxchg128() family of functions is basically & functionally
the same as cmpxchg_double(), but with a saner interface: instead
of a 6-parameter horror that forced u128 - u64/u64-halves layout
details on the interface and exposed users to complexity,
fragility & bugs, use a natural 3-parameter interface with u128 types.
- Restructure the generated atomic headers, and add
kerneldoc comments for all of the generic atomic{,64,_long}_t
operations. Generated definitions are much cleaner now,
and come with documentation.
- Implement lock_set_cmp_fn() on lockdep, for defining an ordering
when taking multiple locks of the same type. This gets rid of
one use of lockdep_set_novalidate_class() in the bcache code.
- Fix raw_cpu_generic_try_cmpxchg() bug due to an unintended
variable shadowing generating garbage code on Clang on certain
ARM builds.

Scheduler changes for v6.5:
- Scheduler SMP load-balancer improvements:
- Avoid unnecessary migrations within SMT domains on hybrid systems.
Problem:
On hybrid CPU systems, (processors with a mixture of higher-frequency
SMT cores and lower-frequency non-SMT cores), under the old code
lower-priority CPUs pulled tasks from the higher-priority cores if
more than one SMT sibling was busy - resulting in many unnecessary
task migrations.
Solution:
The new code improves the load balancer to recognize SMT cores with more
than one busy sibling and allows lower-priority CPUs to pull tasks, which
avoids superfluous migrations and lets lower-priority cores inspect all SMT
siblings for the busiest queue.
- Implement the 'runnable boosting' feature in the EAS balancer: consider CPU
contention in frequency, EAS max util & load-balance busiest CPU selection.
This improves CPU utilization for certain workloads, while leaves other key
workloads unchanged.
- Scheduler infrastructure improvements:
- Rewrite the scheduler topology setup code by consolidating it
into the build_sched_topology() helper function and building
it dynamically on the fly.
- Resolve the local_clock() vs. noinstr complications by rewriting
the code: provide separate sched_clock_noinstr() and
local_clock_noinstr() functions to be used in instrumentation code,
and make sure it is all instrumentation-safe.
- Fixes:
- Fix a kthread_park() race with wait_woken()
- Fix misc wait_task_inactive() bugs unearthed by the -rt merge:
- Fix UP PREEMPT bug by unifying the SMP and UP implementations.
- Fix task_struct::saved_state handling.
- Fix various rq clock update bugs, unearthed by turning on the rq clock
debugging code.
- Fix the PSI WINDOW_MIN_US trigger limit, which was easy to trigger by
creating enough cgroups, by removing the warnign and restricting
window size triggers to PSI file write-permission or CAP_SYS_RESOURCE.
- Propagate SMT flags in the topology when removing degenerate domain
- Fix grub_reclaim() calculation bug in the deadline scheduler code
- Avoid resetting the min update period when it is unnecessary, in
psi_trigger_destroy().
- Don't balance a task to its current running CPU in load_balance(),
which was possible on certain NUMA topologies with overlapping
groups.
- Fix the sched-debug printing of rq->nr_uninterruptible
- Cleanups:
- Address various -Wmissing-prototype warnings, as a preparation
to (maybe) enable this warning in the future.
- Remove unused code
- Mark more functions __init
- Fix shadow-variable warnings

dm: get rid of GFP_NOIO workarounds for __vmalloc and kvmalloc
In the past, the function __vmalloc didn't respect the GFP flags - it allocated memory with the provided gfp flags, but it allocated page tables with GFP_KERNEL. This was fixed in commit |

dm integrity: only allocate recalculate buffer when needed
dm-integrity preallocated 8MiB buffer for recalculating in the constructor and freed it in the destructor. This wastes memory when the user has many dm-integrity devices. Fix dm-integrity so that the buffer is only allocated when recalculation is in progress; allocate the buffer at the beginning of integrity_recalc() and free it at the end. Note that integrity_recalc() doesn't hold any locks when allocating the buffer, so it shouldn't cause low-memory deadlock.

dm integrity: reduce vmalloc space footprint on 32-bit architectures
It was reported that dm-integrity runs out of vmalloc space on 32-bit architectures. On x86, there is only 128MiB vmalloc space and dm-integrity consumes it quickly because it has a 64MiB journal and 8MiB recalculate buffer. Fix this by reducing the size of the journal to 4MiB and the size of the recalculate buffer to 1MiB, so that multiple dm-integrity devices can be created and activated on 32-bit architectures.
