Miquel Raynal 090bb80370 ata: libahci: do not complain in case of deferred probe
Retrieving PHYs can defer the probe, do not spawn an error when
-EPROBE_DEFER is returned, it is normal behavior.

Kees Cook 71d6c505b4 libata: zpodd: Fix small read overflow in zpodd_get_mech_type()
Jeffrin reported a KASAN issue:

  BUG: KASAN: global-out-of-bounds in ata_exec_internal_sg+0x50f/0xc70
  Read of size 16 at addr ffffffff91f41f80 by task scsi_eh_1/149
  ...
  The buggy address belongs to the variable:
    cdb.48319+0x0/0x40

Much like commit 18c9a99bce ("libata: zpodd: small read overflow in
eject_tray()"), this fixes a cdb[] buffer length, this time in
zpodd_get_mech_type():

We read from the cdb[] buffer in ata_exec_internal_sg(). It has to be
ATAPI_CDB_LEN (16) bytes long, but this buffer is only 12 bytes.

Uenal Mutlu 120357ea17 drivers: ata: ahci_sunxi: Increased SATA/AHCI DMA TX/RX FIFOs
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.

Lists of the affected sunxi and other boards and SoCs with SATA using
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.

Tejun Heo ca156e006a libata: don't request sense data on !ZAC ATA devices
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.

Linus Torvalds 22c58fd70c ARM: SoC platform updates
SoC updates, mostly refactorings and cleanups of old legacy platforms.
 Major themes this release:
 
  - Conversion of ixp4xx to a modern platform (drivers, DT, bindings)
  - Moving some of the ep93xx headers around to get it closer to multiplatform enabled.
  - Cleanups of Davinci
 
 This tag also contains a few patches that were queued up as fixes before
 5.1 but I didn't get sent in before release.

Arnd Bergmann 67e38f578a ARM: ep93xx: move pinctrl interfaces into include/linux/soc
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.

Merge tag 'for-5.1/block-20190302' of git://git.kernel.dk/linux-block

Pull block layer updates from Jens Axboe:
 "Not a huge amount of changes in this round, the biggest one is that we
  finally have Mings multi-page bvec support merged. Apart from that,
  this pull request contains:

   - Small series that avoids quiescing the queue for sysfs changes that
     match what we currently have (Aleksei)

   - Series of bcache fixes (via Coly)

   - Series of lightnvm fixes (via Mathias)

   - NVMe pull request from Christoph. Nothing major, just SPDX/license
     cleanups, RR mp policy (Hannes), and little fixes (Bart,
     Chaitanya).

   - BFQ series (Paolo)

   - Save blk-mq cpu -> hw queue mapping, removing a pointer indirection
     for the fast path (Jianchao)

   - fops->iopoll() added for async IO polling, this is a feature that
     the upcoming io_uring interface will use (Christoph, me)

   - Partition scan loop fixes (Dongli)

   - mtip32xx conversion from managed resource API (Christoph)

   - cdrom registration race fix (Guenter)

   - MD pull from Song, two minor fixes.

   - Various documentation fixes (Marcos)

   - Multi-page bvec feature. This brings a lot of nice improvements
     with it, like more efficient splitting, larger IOs can be supported
     without growing the bvec table size, and so on. (Ming)

   - Various little fixes to core and drivers"

John Garry 3bac408a8b ata: libahci: Only warn for AHCI_HFLAG_MULTI_MSI set when genuine custom irq handler implemented
For an AHCI controller with AHCI_HFLAG_MULTI_MSI flag set, we may get the
following log, regardless of whether a custom irq handler was implemented
or not:

[   14.700238] ahci 0000:74:03.0: both AHCI_HFLAG_MULTI_MSI flag set and custom irq handler implemented

This is because we can set hpriv->irq_handler to
ahci_single_level_irq_intr() if not already set, in
ahci_init_one()->ahci_pci_save_initial_config()->ahci_save_initial_config().

Stop having this warn being misleading by adding a check for
hpriv->irq_handler != ahci_single_level_irq_intr.

Merge tag 'v5.0-rc6' into for-5.1/block

Pull in 5.0-rc6 to avoid a dumb merge conflict with fs/iomap.c.
This is needed since io_uring is now based on the block branch,
to avoid a conflict between the multi-page bvecs and the bits
of io_uring that touch the core block parts.

Nathan Chancellor 6f4e626fb0 scsi: ata: Use unsigned int for cmd's type in ioctls in scsi_host_template
Clang warns several times in the scsi subsystem (trimmed for brevity):

drivers/scsi/hpsa.c:6209:7: warning: overflow converting case value to
switch condition type (2147762695 to 18446744071562347015) [-Wswitch]
        case CCISS_GETBUSTYPES:
             ^
drivers/scsi/hpsa.c:6208:7: warning: overflow converting case value to
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.
