186daf2385 io_uring/kbuf: rename REQ_F_PARTIAL_IO to REQ_F_BL_NO_RECYCLE
We only use the flag for this purpose, so rename it accordingly. This
further prevents various other use cases of it, keeping it clean and
consistent. Then we can also check it in one spot, when it's being
attempted recycled, and remove some dead code in io_kbuf_recycle_ring().

9817ad8589 io_uring/net: remove dependency on REQ_F_PARTIAL_IO for sr->done_io
Ensure that prep handlers always initialize sr->done_io before any
potential failure conditions, and with that, we now it's always been
set even for the failure case.

With that, we don't need to use the REQ_F_PARTIAL_IO flag to gate on that.
Additionally, we should not overwrite req->cqe.res unless sr->done_io is
actually positive.

1843671f86 nvme-apple: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

34485c37ea nvme: change shutdown timeout setting message
User visible messages containing the word "timeout" can be alarming.
This one from nvme is just reporting a potentially informative device
configuration, and everything is working as designed. Change the text to
report the less concerning "D3 entry latency", which is where this value
comes from anyway.

====================
ionic: putting ionic on a diet

Building on the performance work done in the previous patchset
    [Link] https://lore.kernel.org/netdev/20240229193935.14197-1-shannon.nelson@amd.com/
this patchset puts the ionic driver on a diet, decreasing the memory
requirements per queue, and simplifies a few more bits of logic.

We trimmed the queue management structs and gained some ground, but
the most savings came from trimming the individual buffer descriptors.
The original design used a single generic buffer descriptor for Tx, Rx and
Adminq needs, but the Rx and Adminq descriptors really don't need all the
info that the Tx descriptors track.  By splitting up the descriptor types
we can significantly reduce the descriptor sizes for Rx and Adminq use.

There is a small reduction in the queue management structs, saving about
3 cachelines per queuepair:

    ionic_qcq:
	Before:	/* size: 2176, cachelines: 34, members: 23 */
	After:	/* size: 2048, cachelines: 32, members: 23 */

We also remove an array of completion descriptor pointers, or about
8 Kbytes per queue.

But the biggest savings came from splitting the desc_info struct into
queue specific structs and trimming out what was unnecessary.

    Before:
	ionic_desc_info:
		/* size: 496, cachelines: 8, members: 10 */
    After:
	ionic_tx_desc_info:
		/* size: 496, cachelines: 8, members: 6 */
	ionic_rx_desc_info:
		/* size: 224, cachelines: 4, members: 2 */
	ionic_admin_desc_info:
		/* size: 8, cachelines: 1, members: 1 */

In a 64 core host the ionic driver will default to 64 queuepairs of
1024 descriptors for Rx, 1024 for Tx, and 80 for Adminq and Notifyq.

The total memory usage for 64 queues:
    Before:
	  65 * sizeof(ionic_qcq)			   141,440
	+ 64 * 1024 * sizeof(ionic_desc_info)		32,505,856
	+ 64 * 1024 * sizeof(ionic_desc_info)		32,505,856
	+ 64 * 1024 * 2 * sizeof(ionic_qc_info)		    16,384
	+  1 *   80 * sizeof(ionic_desc_info)		    39,690
							----------
							65,201,038

    After:
	  65 * sizeof(ionic_qcq)			   133,120
	+ 64 * 1024 * sizeof(ionic_tx_desc_info)	32,505,856
	+ 64 * 1024 * sizeof(ionic_rx_desc_info)	14,680,064
	+                           (removed)		         0
	+  1 *   80 * sizeof(ionic_admin desc_info)	       640
							----------
							47,319,680

This saves us approximately 18 Mbytes per port in a 64 core machine,
a 28% savings in our memory needs.

In addition, this improves our simple single thread / single queue
iperf case on a 9100 MTU connection from 86.7 to 95 Gbits/sec.

65e548f6b0 ionic: remove the cq_info to save more memory
With a little simple math we don't need another struct array to
find the completion structs, so we can remove the ionic_cq_info
altogether.  This doesn't really save anything in the ionic_cq
since it gets padded out to the cacheline, but it does remove
the parallel array allocation of 8 * num_descriptors, or about
8 Kbytes per queue in a default configuration.

ae24a8f88b ionic: remove callback pointer from desc_info
By reworking the queue service routines to have their own
servicing loops we can remove the cb pointer from desc_info
to save another 8 bytes per descriptor,

This simplifies some of the queue handling indirection and makes
the code a little easier to follow, and keeps service code in
one place rather than jumping between code files.

Jeff was retired as the Intel driver maintainer in
commit 6667df916f ("MAINTAINERS: Update MAINTAINERS for

But he has signed-off a lot of patches over the years
so get_maintainer insists on CCing him.

We haven't heard from him since he left Intel, so remapping
the address via mailmap is also pointless. Add to ignored

77292bb8ca crypto: scomp - remove memcpy if sg_nents is 1 and pages are lowmem
while sg_nents is 1, which is always true for the current kernel
as the only user - zswap is this case, we might have a chance to
remove memcpy, thus improve the performance.
Though sg_nents is 1, its buffer might cross two pages. If those
pages are highmem, we have no cheap way to map them to contiguous
virtual address because kmap doesn't support more than one page
(kmap single higmem page could be still expensive for tlb) and
vmap is expensive.
So we also test and enure page is not highmem in order to safely
use page_to_virt before removing the memcpy. The good news is
that in the most majority of cases, we are lowmem, and we are
always lowmem in those modern and popular hardware.

b446631f35 dpll: fix dpll_xa_ref_*_del() for multiple registrations
Currently, if there are multiple registrations of the same pin on the
same dpll device, following warnings are observed:
WARNING: CPU: 5 PID: 2212 at drivers/dpll/dpll_core.c:143 dpll_xa_ref_pin_del.isra.0+0x21e/0x230
WARNING: CPU: 5 PID: 2212 at drivers/dpll/dpll_core.c:223 __dpll_pin_unregister+0x2b3/0x2c0

The problem is, that in both dpll_xa_ref_dpll_del() and
dpll_xa_ref_pin_del() registration is only removed from list in case the
reference count drops to zero. That is wrong, the registration has to
be removed always.

To fix this, remove the registration from the list and free
it unconditionally, instead of doing it only when the ref reference
counter reaches zero.
