It doesn't make sense for a perf event to be configured as a CHAIN event
in isolation, so extend the arm_pmu structure with a ->filter_match()

There is no reason to open code what the switch setup function does, in
fact, because we just issued a switch reset, we would make all the

port be enabled again and wasting power and leading to an inappropriate
switch core clock being selected.

The order in which we release resources is unfortunately leading to bus
errors while dismantling the port. This is because we set
priv->wol_ports_mask to 0 to tell bcm_sf2_sw_suspend() that it is now
permissible to clock gate the switch. Later on, when dsa_slave_destroy()
comes in from dsa_unregister_switch() and calls
dsa_switch_ops::port_disable, we perform the same dismantling again, and
this time we hit registers that are clock gated.
Make sure that dsa_unregister_switch() is the first thing that happens,
which takes care of releasing all user visible resources, then proceed
with clock gating hardware. We still need to set priv->wol_ports_mask to
0 to make sure that an enabled port properly gets disabled in case it
was previously used as part of Wake-on-LAN.

It has been reported that since
commit 05212ba813 ("r8169: set RxConfig after tx/rx is enabled for RTL8169sb/8110sb devices")
at least RTL_GIGA_MAC_VER_38 NICs work erratically after a resume from
suspend.
The problem has been traced to a missing RX_MULTI_EN bit in the RxConfig
register.
We already set this bit for RTL_GIGA_MAC_VER_35 NICs of the same 8168F
chip family so let's do it also for its other siblings: RTL_GIGA_MAC_VER_36
and RTL_GIGA_MAC_VER_38.
Curiously, the NIC seems to work fine after a system boot without having
this bit set as long as the system isn't suspended and resumed.

During boot, mlx4_core sets the driverinit configuration parameters and
updates the devlink module on the initial values calling
devlink_param_driverinit_value_set().
If devlink_param_driverinit_value_set() returns an error mlx4_core
reports kernel module warning.
This caused false alarm during boot in case kernel was compiled with
CONFIG_NET_DEVLINK off.
Fix by removing warning reported in case
devlink_param_driverinit_value_set() fails.
This actually makes the function mlx4_devlink_set_init_value()
redundant to using directly devlink_param_driverinit_value_set() and so
removed.
It fixes the following kernel trace:
mlx4_core 0000:00:06.0: devlink set parameter 0 value failed (err = -95)
mlx4_core 0000:00:06.0: devlink set parameter 1 value failed (err = -95)

dm linear: fix linear_end_io conditional definition
The dm-linear target is independent of the dm-zoned target. For code
requiring support for zoned block devices, use CONFIG_BLK_DEV_ZONED
instead of CONFIG_DM_ZONED.
While at it, similarly to dm linear, also enable the DM_TARGET_ZONED_HM
feature in dm-flakey only if CONFIG_BLK_DEV_ZONED is defined.

It is best to avoid any extra overhead associated with bio completion.
DM core will indirectly call a DM target's .end_io if it is defined.
In the case of DM linear, there is no need to do so (for every bio that
completes) if CONFIG_DM_ZONED is not enabled.
Avoiding an extra indirect call for every bio completion is very
important for ensuring DM linear doesn't incur more overhead that
further widens the performance gap between dm-linear and raw block
devices.

Since 'commit 02e389e63e ("pinctrl: mcp23s08: fix irq setup order")' the
irq request isn't the last devm_* allocation. Without a deeper look at
the irq and testing this isn't a good solution. Since this driver relies
on the devm mechanism, requesting a interrupt should be the last thing
to avoid memory corruptions during unbinding.
'Commit 02e389e63e ("pinctrl: mcp23s08: fix irq setup order")' fixed the
order for the interrupt-controller use case only. The
mcp23s08_irq_setup() must be split into two to fix it for the
interrupt-controller use case and to register the irq at last. So the
irq will be freed first during unbind.

gpiochip_set_cascaded_irqchip() is passed 'parent_irq' as an argument
and then the address of that argument is assigned to the gpio chips
gpio_irq_chip 'parents' pointer shortly thereafter. This can't ever
work, because we've just assigned some stack address to a pointer that
we plan to dereference later in gpiochip_irq_map(). I ran into this
issue with the KASAN report below when gpiochip_irq_map() tried to setup
the parent irq with a total junk pointer for the 'parents' array.

Let's leave around one unsigned int in the gpio_irq_chip struct for the
single parent irq case and repoint the 'parents' array at it. This way
code is left mostly intact to setup parents and we waste an extra few
bytes per structure of which there should be only a handful in a system.

If dm-linear or dm-flakey are layered on top of a partition of a zoned
block device, remapping of the start sector and write pointer position
of the zones reported by a report zones BIO must be modified to account
for the target table entry mapping (start offset within the device and
entry mapping with the dm device). If the target's backing device is a
partition of a whole disk, the start sector on the physical device of
the partition must also be accounted for when modifying the zone
information. However, dm_remap_zone_report() was not considering this
last case, resulting in incorrect zone information remapping with
targets using disk partitions.
Fix this by calculating the target backing device start sector using
the position of the completed report zones BIO and the unchanged
position and size of the original report zone BIO. With this value
calculated, the start sector and write pointer position of the target
zones can be correctly remapped.

napi poll functions should be initialized before running request_irq(),
to handle a rare condition where there is a pending interrupt, causing
the ISR to fire immediately while the poll function wasn't set yet,
causing a NULL dereference.

In a rare scenario when ena_device_restore() fails, followed by device
remove, an FLR will not be issued. In this case, the device will keep
sending asynchronous AENQ keep-alive events, even after driver removal,
leading to memory corruption.

Memory mapped with devm_ioremap is automatically freed when the driver
is disconnected from the device. Therefore there is no need to
explicitly call devm_iounmap.

On some SD cards over SPI, reading with the multiblock read command the last
sector will leave the card in a bad state.
Remove last sectors from the multiblock reading cmd.

Use the of_get_child_by_name() helper instead of open coding searching
for the '/options' node. This removes directly accessing the name
pointer as well.

On Sun Ultra 5, it happens that the dot clock is not set up properly for
some videomodes. For example, if we set the videomode "r1024x768x60" in
the firmware, Linux would incorrectly set a videomode with refresh rate
180Hz when booting (suprisingly, my LCD monitor can display it, although
display quality is very low).
The reason is this: Older mach64 cards set the divider in the register
VCLK_POST_DIV. The register has four 2-bit fields (the field that is
actually used is specified in the lowest two bits of the register
CLOCK_CNTL). The 2 bits select divider "1, 2, 4, 8". On newer mach64 cards,
there's another bit added - the top four bits of PLL_EXT_CNTL extend the
divider selection, so we have possible dividers "1, 2, 4, 8, 3, 5, 6, 12".
The Linux driver clears the top four bits of PLL_EXT_CNTL and never sets
them, so it can work regardless if the card supports them. However, the
sparc64 firmware may set these extended dividers during boot - and the
mach64 driver detects incorrect dot clock in this case.
This patch makes the driver read the additional divider bit from
PLL_EXT_CNTL and calculate the initial refresh rate properly.
