Jeremy Dorfman identified mutex contention when multiple threads
parse /proc/stat concurrently.
Since commit 425a5072dc ("genirq: Free irq_desc with rcu"),
kstat_irqs_usr() can be switched to rcu locking, which removes this mutex
contention.

Commit 0198d7bb8a ("ASoC: omap-mcbsp: Convert to use the sdma-pcm
instead of omap-pcm") resulted in broken audio playback on OMAP1510
(discovered on Amstrad Delta).
When running on OMAP1510, omap-pcm used to obtain DMA offset from
snd_dmaengine_pcm_pointer_no_residue() based on DMA interrupt triggered
software calculations instead of snd_dmaengine_pcm_pointer() which
depended on residue value calculated from omap_dma_get_src_pos().
Similar code path is still available in now used
sound/soc/soc-generic-dmaengine-pcm.c but it is not triggered.
It was verified already before that omap_get_dma_src_pos() from
arch/arm/plat-omap/dma.c didn't work correctly for OMAP1510 - see
commit 1bdd741991 ("ASoC: OMAP: fix OMAP1510 broken PCM pointer
callback") for details. Apparently the same applies to its successor,
omap_dma_get_src_pos() from drivers/dma/ti/omap-dma.c.
On the other hand, snd_dmaengine_pcm_pointer_no_residue() is described
as depreciated and discouraged for use in new drivers because of its
unreliable accuracy. However, it seems the only working option for
OPAM1510 now, as long as a software calculated residue is not
implemented as OMAP1510 fallback in omap-dma.
Using snd_dmaengine_pcm_pointer_no_residue() code path instead of
snd_dmaengine_pcm_pointer() in sound/soc/soc-generic-dmaengine-pcm.c
can be triggered in two ways:
- by passing pcm->flags |= SND_DMAENGINE_PCM_FLAG_NO_RESIDUE from
sound/soc/omap/sdma-pcm.c,
- by passing dma_caps.residue_granularity =
DMA_RESIDUE_GRANULARITY_DESCRIPTOR from DMA engine.
Let's do the latter.

Linux driver when receives Broadcast Asynchronous Event Notification (BAEN)
from the controller firmware, checks all pending I/Os at the driver level
and issues query task, abort task TMs. This is done in the driver to handle
drives which are connected with multiple initiators and undergoing target
resets. In the BAEN handling code, the I/Os issued to NVMe drives are also
handled and query task and abort task TMs are issued, which are not
necessary as there is no multi-initiator and no BAEN concept with NVMe
drives. Hence when the driver checks for pending I/Os it skips NVMe drives
at this moment.

on some architectures like arm64. This ends up with CPU observing two
barriers back to back before executing the register write.
Drivers should generally assume that the barrier implied by writel() is
sufficient for ordering DMA. Remove the extraneous wmb() before it.

Generally target core and TCMUser seem to work fine for tape devices and
media changers. But there is at least one situation where TCMUser is not
able to support sequential access device emulation correctly.
The situation is when an initiator sends a SCSI READ CDB with a length that
is greater than the length of the tape block to read. We can distinguish
two subcases:
A) The initiator sent the READ CDB with the SILI bit being set.
In this case the sequential access device has to transfer the data from
the tape block (only the length of the tape block) and transmit a good
status. The current interface between TCMUser and the userspace does
not support reduction of the read data size by the userspace program.
The patch below fixes this subcase by allowing the userspace program to
specify a reduced data size in read direction.
B) The initiator sent the READ CDB with the SILI bit not being set.
In this case the sequential access device has to transfer the data from
the tape block as in A), but additionally has to transmit CHECK
CONDITION with the ILI bit set and NO SENSE in the sensebytes. The
information field in the sensebytes must contain the residual count.
With the below patch a user space program can specify the real read data
length and appropriate sensebytes. TCMUser then uses the se_cmd flag
SCF_TREAT_READ_AS_NORMAL, to force target core to transmit the real data
size and the sensebytes. Note: the flag SCF_TREAT_READ_AS_NORMAL is
introduced by Lee Duncan's patch "[PATCH v4] target: transport should
handle st FM/EOM/ILI reads" from Tue, 15 May 2018 18:25:24 -0700.

jfs: Fix inconsistency between memory allocation and ea_buf->max_size
Pull s390 updates from Martin Schwidefsky:
"common I/O layer
- Fix bit-fields crossing storage-unit boundaries in css_general_char
dasd driver
- Avoid a sparse warning in regard to the queue lock
- Allocate the struct dasd_ccw_req as per request data. Only for
internal I/O is the structure allocated separately
- Remove the unused function dasd_kmalloc_set_cda
- Save a few bytes in struct dasd_ccw_req by reordering fields
- Convert remaining users of dasd_kmalloc_request to
dasd_smalloc_request and remove the now unused function
vfio/ccw
- Refactor and improve pfn_array_alloc_pin/pfn_array_pin
- Add a new tracepoint for failed vfio/ccw requests
- Add a CCW translation improvement to accept more requests as valid
- Bug fixes"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
s390/dasd: only use preallocated requests
s390/dasd: reshuffle struct dasd_ccw_req
s390/dasd: remove dasd_kmalloc_set_cda
s390/dasd: move dasd_ccw_req to per request data
s390/dasd: simplify locking in process_final_queue
s390/cio: sanitize css_general_characteristics definition
vfio: ccw: add tracepoints for interesting error paths
vfio: ccw: set ccw->cda to NULL defensively
vfio: ccw: refactor and improve pfn_array_alloc_pin()
vfio: ccw: shorten kernel doc description for pfn_array_pin()
vfio: ccw: push down unsupported IDA check
vfio: ccw: fix error return in vfio_ccw_sch_event
s390/archrandom: Rework arch random implementation.
s390/net: add pnetid support
The patch fixed a W=1 warning but broke the ia64 build:
CC mm/memblock.o
mm/memblock.c:1340: error: redefinition of `memblock_virt_alloc_try_nid_raw'
./include/linux/bootmem.h:335: error: previous definition of `memblock_virt_alloc_try_nid_raw' was here
Because inlcude/linux/bootmem.h says
#if defined(CONFIG_HAVE_MEMBLOCK) && defined(CONFIG_NO_BOOTMEM)
whereas mm/Makefile says
obj-$(CONFIG_HAVE_MEMBLOCK) += memblock.o
So revert 26f09e9b3a ("mm/memblock: add missing include
<linux/bootmem.h>") while a full fix can be worked on.
Fixes: 26f09e9b3a ("mm/memblock: add missing include <linux/bootmem.h>")
