At the beginning, only Armada 38x SoCs where supported by the
ahci_mvebu.c driver. Commit 15d3ce7b63bd ("ata: ahci_mvebu: add
support for Armada 3700 variant") introduced Armada 3700 support. As
opposed to Armada 38x SoCs, the 3700 variants do not have to configure
mbus and the regret option. This patch took care of avoiding such
configuration when not needed in the probe function, but failed to do
the same in the resume path. While doing so looks harmless by
experience, let's clean the driver logic and avoid doing this useless
configuration with Armada 3700 SoCs.
Because the logic is very similar between these two places, it has
been decided to factorize this code and put it in a "Armada 38x
configuration function". This function is part of a new
(per-compatible) platform data structure, so that the addition of such
configuration function for Armada 3700 will be eased.

For Armada-38x (32-bit) SoCs, PM platform support has been added since:
commit 32f9494c9dfd ("ARM: mvebu: prepare pm-board.c for the
introduction of Armada 38x support")
commit 3cbd6a6ca81c ("ARM: mvebu: Add standby support")
For Armada 64-bit SoCs, like the A3700 also using this AHCI driver, PM
platform support has always existed.
There are even suspend/resume hooks in this driver since:
commit d6ecf15814888 ("ata: ahci_mvebu: add suspend/resume support")
Remove the stale comment at the end of this driver stating that all
the above does not exist yet.

Current implementation of the libahci does not take into account the
new PHY framework. Correct the situation by adding a call to
phy_set_mode() before phy_power_on().
PHYs should also be handled at suspend/resume time. For this, call
ahci_platform_enable/disable_phys() at suspend/resume_host() time. These
calls are guarded by a HFLAG (AHCI_HFLAG_SUSPEND_PHYS) that the user of
the libahci driver must set manually in hpriv->flags at probe time. This
is to avoid breaking users that have not been tested with this change.

smp_rescan_cpus() is called without the device_hotplug_lock, which can lead
to a dedlock when a new CPU is found and immediately set online by a udev
rule.
This was observed on an older kernel version, where the cpu_hotplug_begin()
loop was still present, and it resulted in hanging chcpu and systemd-udev
processes. This specific deadlock will not show on current kernels. However,
there may be other possible deadlocks, and since smp_rescan_cpus() can still
trigger a CPU hotplug operation, the device_hotplug_lock should be held.
For reference, this was the deadlock with the old cpu_hotplug_begin() loop:
chcpu (rescan) systemd-udevd
echo 1 > /sys/../rescan
-> smp_rescan_cpus()
-> (*) get_online_cpus()
(increases refcount)
-> smp_add_present_cpu()
(new CPU found)
-> register_cpu()
-> device_add()
-> udev "add" event triggered -----------> udev rule sets CPU online
-> echo 1 > /sys/.../online
-> lock_device_hotplug_sysfs()
(this is missing in rescan path)
-> device_online()
-> (**) device_lock(new CPU dev)
-> cpu_up()
-> cpu_hotplug_begin()
(loops until refcount == 0)
-> deadlock with (*)
-> bus_probe_device()
-> device_attach()
-> device_lock(new CPU dev)
-> deadlock with (**)
Fix this by taking the device_hotplug_lock in the CPU rescan path.

Try to get reference for ldisc during tty_reopen().
If ldisc present, we don't need to do tty_ldisc_reinit() and lock the
write side for line discipline semaphore.
Effectively, it optimizes fast-path for tty_reopen(), but more
importantly it won't interrupt ongoing IO on the tty as no ldisc change
is needed.
Fixes user-visible issue when tty_reopen() interrupted login process for
user with a long password, observed and reported by Lukas.

Since commit 89a5e15bcba87d ("gpio/mmc/of: Respect polarity in the device
tree") gpiolib-of parses the "cd-gpios" property and flips the polarity
if "cd-inverted" is also set. This results in the "cd-inverted" property
being evaluated twice, which effectively makes it a no-op:
- first in drivers/gpio/gpiolib-of.c (of_xlate_and_get_gpiod_flags) when
setting up the CD GPIO
- then again in drivers/mmc/core/slot-gpio.c (mmc_gpio_get_cd) when
reading the CD GPIO value at runtime
On boards which are using device-tree with the "cd-inverted" property
being set any inserted card are not detected anymore. This is due to the
MMC core treating the CD GPIO with the wrong polarity.
Disable "override_cd_active_level" for the card detection GPIO which is
parsed using mmc_of_parse. This fixes SD card detection on the boards
which are currently using the "cd-inverted" device-tree property (tested
on Meson8b Odroid-C1 and Meson8b EC-100).
This does not remove the CD GPIO inversion logic from the MMC core
because there's at least one driver (sdhci-pci-core for Intel BayTrail
based boards) which still passes "override_cd_active_level = true" to
mmc_gpiod_request_cd(). Due to lack of hardware for testing this is left
untouched.
In the future the GPIO inversion logic for both, card and read-only
detection can be removed once no driver is using it anymore.

Commit 5c63e407aaab ("fbdev: Convert to using %pOFn instead of
device_node.name") changed how the OF FB driver handles the OF node
name. This missed the case where the node name is passed to
offb_init_palette_hacks(). This results in a NULL ptr dereference
in strncmp and breaks any system except ones using bootx with no display
node.
Fix this by making offb_init_palette_hacks() use the OF node pointer and
use of_node_name_prefix() helper function instead for node name
comparisons. This helps in moving all OF node name accesses to helper
functions in preparation to remove struct device_node.name pointer.

The binderfs instance in the initial ipc namespace will always have a
reserve of 4 binder devices unless explicitly capped by specifying a lower

This ensures when binder devices are removed (on accident or on purpose)
they can always be recreated without risking that all minor numbers have
already been used up.

Whilst iommu_probe_device() does check for non-NULL ops as the previous
code did, it does not do so in the same order relative to the other
checks, and as a result means that -EPROBE_DEFER returned by of_xlate()
(plus any real error condition too) gets overwritten with -EINVAL and
leads to various misbehaviour.
Reinstate the original logic, but without implicitly relying on ops
being set to infer !err as the initial condition (now that the validity
of ops for its own sake is checked elsewhere).

Since binderfs can be mounted by userns root in non-initial user namespaces
some precautions are in order. First, a way to set a maximum on the number
of binder devices that can be allocated per binderfs instance and second, a
way to reserve a reasonable chunk of binderfs devices for the initial ipc
namespace.
A first approach as seen in [1] used sysctls similiar to devpts but was
shown to be flawed (cf. [2] and [3]) since some aspects were unneeded. This
is an alternative approach which avoids sysctls completely and instead
switches to a single mount option.
Starting with this commit binderfs instances can be mounted with a limit on
the number of binder devices that can be allocated. The max=<count> mount
option serves as a per-instance limit. If max=<count> is set then only
<count> number of binder devices can be allocated in this binderfs
instance.
This allows to safely bind-mount binderfs instances into unprivileged user
namespaces since userns root in a non-initial user namespace cannot change
the mount option as long as it does not own the mount namespace the
binderfs mount was created in and hence cannot drain the host of minor
device numbers

If adapter->retries is set to a minus value from user space via ioctl,
it will make __i2c_transfer and __i2c_smbus_xfer skip the calling to
adapter->algo->master_xfer and adapter->algo->smbus_xfer that is
registered by the underlying bus drivers, and return value 0 to all the
callers. The bus driver will never be accessed anymore by all users,
besides, the users may still get successful return value without any
error or information log print out.
If adapter->timeout is set to minus value from user space via ioctl,
it will make the retrying loop in __i2c_transfer and __i2c_smbus_xfer
always break after the the first try, due to the time_after always
returns true.

maybe other boards using this generic driver are affected
v2:
optimization:
- phy_set_max_speed() is only needed if you want to reduce the
max speed, typically if the PHY supports 1Gbps but the MAC
supports 100Mbps only.
- The pause parameters are autonegotiated. Except you have a specific
need you normally don't need to manually fiddle with this.
- phy_start_aneg() is called implicitly by the phylib state machine,
you shouldn't call it manually except you have a good excuse.
- netif_carrier_on/netif_carrier_off in mtk_phy_link_adjust() isn't
needed. It's done by phy_link_change() in phylib.

Pull RISC-V updates from Palmer Dabbelt:
"This tag contains a handful of updates that slipped through the cracks
during the merge window due to the holidays. The fixes are mostly
independent, with the exception of one larger audit-related branch.
Core RISC-V updates:
- The BSS has been moved, which shrinks flat images.
- A fix to test-bpf so it compiles on RV64I-based systems.
- A fix to respect the kernel commandline when there is no device
tree.
- A fix to prevent CPUs from trying to put themselves to sleep when
bringing down the system.
- Support for MODULE_SECTIONS on RV32I-based systems.
- [new in v2] The addition of an SBI earlycon driver. This is
definately a new feature, but I'd like to include it now because I
dropped this patch when submitting the merge window PR that removed
our EARLY_PRINTK support.
RISC-V audit updates:
- The addition of NR_syscalls into unistd.h, which is necessary for
CONFIG_FTRACE_SYSCALLS.
- The definition of CREATE_TRACE_POINTS so __tracepoint_sys_{enter,exit}
get defined.
- A fix for trace_sys_exit() so we can enable HAVE_SYSCALL_TRACEPOINTS
As usual, I've tested this by booting a Fedora-based image on a recent
QEMU (this time just whatever I had lying around).

The dm-crypt cipher specification in a mapping table is defined as:
cipher[:keycount]-chainmode-ivmode[:ivopts]
or (new crypt API format):
capi:cipher_api_spec-ivmode[:ivopts]
For ESSIV, the parameter includes hash specification, for example:
aes-cbc-essiv:sha256
The implementation expected that additional IV option to never include
another dash '-' character.
But, with SHA3, there are names like sha3-256; so the mapping table
parser fails:
dmsetup create test --table "0 8 crypt aes-cbc-essiv:sha3-256 9c1185a5c5e9fc54612808977ee8f5b9e 0 /dev/sdb 0"
or (new crypt API format)
dmsetup create test --table "0 8 crypt capi:cbc(aes)-essiv:sha3-256 9c1185a5c5e9fc54612808977ee8f5b9e 0 /dev/sdb 0"
device-mapper: crypt: Ignoring unexpected additional cipher options
device-mapper: table: 253:0: crypt: Error creating IV
device-mapper: ioctl: error adding target to table
Fix the dm-crypt constructor to ignore additional dash in IV options and
also remove a bogus warning (that is ignored anyway).
