There is no more 'altr,gpio-bank-width' in the 'altr,pio-1.0' driver.
There is a 'altr,ngpio' which is what the property wants to configure.
This change updates all occurrences of 'altr,gpio-bank-width' to
'altr,ngpio'.

This patch adds support for common clock framework on Nios2. Clock
framework is commonly used in many drivers, and this patch makes it
available for the entire architecture, not just on a per-driver basis.

Moreover, it is improper to break UAPI, strace uses the definitions to

Restore the macro definition and put it under "#ifndef __KERNEL__"

When kdump is not configured, a Hyper-V VM might still respond to
network traffic after a kernel panic when kernel parameter panic=0.
The panic CPU goes into an infinite loop with interrupts enabled,
and the VMbus driver interrupt handler still works because the
VMbus connection is unloaded only in the kdump path. The network
responses make the other end of the connection think the VM is
still functional even though it has panic'ed, which could affect any
failover actions that should be taken.
Fix this by unloading the VMbus connection during the panic process.
vmbus_initiate_unload() could then be called twice (e.g., by
hyperv_panic_event() and hv_crash_handler(), so reset the connection
state in vmbus_initiate_unload() to ensure the unload is done only
once.

We can't reliably wait in io_ring_ctx_wait_and_kill(), since the
task_works list isn't ordered (in fact it's LIFO ordered). We could
either fix this with a separate task_works list for io_uring work, or
just punt the wait-and-free to async context. This ensures that
task_work that comes in while we're shutting down is processed
correctly. If we don't go async, we could have work past the fput()
work for the ring that depends on work that won't be executed until
after we're done with the wait-and-free. But as this operation is
blocking, it'll never get a chance to run.
This was reproduced with hundreds of thousands of sockets running
memcached, haven't been able to reproduce this synthetically.

With amdgpu and CONFIG_TRANSPARENT_HUGEPAGE_ALWAYS=y, there are
errors like:
BUG: non-zero pgtables_bytes on freeing mm
and:
BUG: Bad rss-counter state
with TTM transparent huge-pages.
Until we've figured out what other TTM drivers do differently compared to
vmwgfx, disable the huge_fault() callback, eliminating transhuge

them so they're not included yet.
* SBI v0.2 support.

This builds and boots for me. There is one merge conflict, it's just a Kconfig

I don't anticipate a part two, but I'll probably have something early in the

In rds_free_mr(), it calls rds_destroy_mr(mr) directly. But this
defeats the purpose of reference counting and makes MR free handling
impossible. It means that holding a reference does not guarantee that
it is safe to access some fields. For example, In
rds_cmsg_rdma_dest(), it increases the ref count, unlocks and then
calls mr->r_trans->sync_mr(). But if rds_free_mr() (and
rds_destroy_mr()) is called in between (there is no lock preventing
this to happen), r_trans_private is set to NULL, causing a panic.
Similar issue is in rds_rdma_unuse().

The problem is that because wait_pidfd.lock is taken under the tasklist
lock. It must always be taken with irqs disabled as tasklist_lock can be
taken from interrupt context and if wait_pidfd.lock was already taken this
would create a lock order inversion.
Oleg suggested just disabling irqs where I have added extra calls to
wait_pidfd.lock. That should be safe and I think the code will eventually
do that. It was rightly pointed out by Christian that sharing the
wait_pidfd.lock was a premature optimization.
It is also true that my pre-merge window testing was insufficient. So
remove the premature optimization and give struct pid a dedicated lock of
it's own for struct pid things. I have verified that lockdep sees all 3
paths where we take the new pid->lock and lockdep does not complain.
It is my current day dream that one day pid->lock can be used to guard the
task lists as well and then the tasklist_lock won't need to be held to
deliver signals. That will require taking pid->lock with irqs disabled.

If the local node id(qrtr_local_nid) is not modified after its
initialization, it equals to the broadcast node id(QRTR_NODE_BCAST).
So the messages from local node should not be taken as broadcast
and keep the process going to send them out anyway.
The definitions are as follow:
static unsigned int qrtr_local_nid = NUMA_NO_NODE;

If completion queue overflow occurs, __io_cqring_fill_event() will
update req->cflags, which is in a union with req->work and happens to
be aliased to req->work.fs. Following io_free_req() ->

Analogix_dp driver acquires all its resources in the ->bind() callback,
what is a bit against the component driver based approach, where the
driver initialization is split into a probe(), where all resources are
gathered, and a bind(), where all objects are created and a compound
driver is initialized.
Extract all the resource related operations to analogix_dp_probe() and
analogix_dp_remove(), then call them before/after registration of the
device components from the main Exynos DP and Rockchip DP drivers. Also
move the plat_data initialization to the probe() to make it available for
the analogix_dp_probe() function.
This fixes the multiple calls to the bind() of the DRM compound driver
when the DP PHY driver is not yet loaded/probed:

9p: document short read behaviour with O_NONBLOCK
- support for asynchronous create and unlink (Jeff Layton). Creates
and unlinks are satisfied locally, without waiting for a reply from
the MDS, provided the client has been granted appropriate caps (new
in v15.y.z ("Octopus") release). This can be a big help for metadata
heavy workloads such as tar and rsync. Opt-in with the new nowsync
mount option.
- multiple blk-mq queues for rbd (Hannes Reinecke and myself). When
the driver was converted to blk-mq, we settled on a single blk-mq
queue because of a global lock in libceph and some other technical
debt. These have since been addressed, so allocate a queue per CPU
to enhance parallelism.
- don't hold onto caps that aren't actually needed (Zheng Yan). This
has been our long-standing behavior, but it causes issues with some
active/standby applications (synchronous I/O, stalls if the standby
goes down, etc).
- .snap directory timestamps consistent with ceph-fuse (Luis Henriques)
