Merge tag 'for-5.3/libata-20190708' of git://git.kernel.dk/linux-block
Pull libata updates from Jens Axboe:
"These are the changes that are reviewed, tested, and queued up for
this merge window. This contains:
- Removal of redundant memset after dmam_alloc_coherent (Fuqian)
- Expand blacklist check for ST1000LM024, making it independent of
firmware version (Hans)
- Request sense fix (Tejun)
- ahci_sunxi FIFO fix (Uenal)"
* tag 'for-5.3/libata-20190708' of git://git.kernel.dk/linux-block:
drivers: ata: ahci_sunxi: Increased SATA/AHCI DMA TX/RX FIFOs
libata: Drop firmware version check from the ST1000LM024 quirk
ata: sata_sil24: Remove call to memset after dmam_alloc_coherent
ata:sata_qstor: Remove call to memset after dmam_alloc_coherent
ata: sata_nv: Remove call to memset after dmam_alloc_coherent
ata: pdc_adma: Remove call to memset after dmam_alloc_coherent
ata: libahci: Remove call to memset after dmam_alloc_coherent
ata: acard-ahci: Remove call to memset after dmam_alloc_coherent
libata: don't request sense data on !ZAC ATA devices
Increasing the SATA/AHCI DMA TX/RX FIFOs (P0DMACR.TXTS and .RXTS, ie.
TX_TRANSACTION_SIZE and RX_TRANSACTION_SIZE) from default 0x0 each
to 0x3 each, gives a write performance boost of 120 MiB/s to 132 MiB/s
from lame 36 MiB/s to 45 MiB/s previously.
Read performance is above 200 MiB/s.
[tested on SSD using dd bs=4K/8K/12K/16K/20K/24K/32K: peak-perf at 12K]
Tested on the SBCs Banana Pi R1 (aka Lamobo R1) and Banana Pi M1 which
are based on the Allwinner A20 32bit-SoC (ARMv7-a / arm-linux-gnueabihf).
These devices are RaspberryPi-like small devices.
This problem of slow SATA write-speed with these small devices lasts
for about 7 years now (beginning with the A10 SoC). Many commentators
throughout the years wrongly assumed the slow write speed was a
hardware limitation. This patch finally solves the problem, which
in fact was just a hard-to-find software problem due to lack of
SATA/AHCI documentation by the SoC-maker Allwinner Technology.

the ahci_sunxi driver:

There are several firmware versions between version 2AR10001 and
2BA30001, presumably these also have broken FPDMA_AA activation, so
lets play it safe and apply the quirk to all firmware versions.

ZAC support added sense data requesting on error for both ZAC and ATA
devices. This seems to cause erratic error handling behaviors on some
SSDs where the device reports sense data availability and then
delivers the wrong content making EH take the wrong actions. The
failure mode was sporadic on a LITE-ON ssd and couldn't be reliably
reproduced.
There is no value in requesting sense data from non-ZAC ATA devices
while there's a significant risk of introducing EH misbehaviors which
are difficult to reproduce and fix. Let's do the sense data dancing
only for ZAC devices.

to system lockups. So it seems that these models are buggy in more then
1 way. Add NOLPM quirk to the existing quirks entry for BROKEN_FPDMA_AA.

ep93xx does not have a proper pinctrl driver, but does things
ad-hoc through mach/platform.h, which is also used for setting
up the boards.
To avoid using mach/*.h headers completely, let's move the interfaces
into include/linux/soc/. This is far from great, but gets the job
done here, without the need for a proper pinctrl driver.

Clang warns several times in the scsi subsystem (trimmed for brevity):

switch condition type (2147762694 to 18446744071562347014) [-Wswitch]
case CCISS_GETHEARTBEAT:
^
The root cause is that the _IOC macro can generate really large numbers,
which don't fit into type 'int', which is used for the cmd parameter in
the ioctls in scsi_host_template. My research into how GCC and Clang are
handling this at a low level didn't prove fruitful. However, looking at
the rest of the kernel tree, all ioctls use an 'unsigned int' for the
cmd parameter, which will fit all of the _IOC values in the scsi/ata
subsystems.
Make that change because none of the ioctls expect a negative value for
any command, it brings the ioctls inline with the reset of the kernel,
and it removes ambiguity, which is never good when dealing with compilers.

In some cases, the system bus can be configured for 16-bit mode,
in this case using read/write functions for 32-bit values
results in two cycles of 16 bits each, which is wrong.
This patch adds the devicetree flag to switch the driver to
use 16-bit mode for I/O transfers.
