Allow the creation of conventional zones by adding the zone_nr_conv
configuration attribute. This new attribute is used only for zoned devices
and indicates the number of conventional zones to create. The default value
is 0. Since host-managed zoned block devices must always have at least one
sequential zone, if the value of zone_nr_conv is larger than or equal to
the total number of zones of the device nr_zones, zone_nr_conv is
automatically changed to nr_zones - 1.

The documentation for the .raw_event() callback says that if the
driver return 1, there will be no further processing of the event,
but this is not true, the actual code in hid-core.c looks like this:

  if (hdrv && hdrv->raw_event && hid_match_report(hid, report)) {
           ret = hdrv->raw_event(hid, report, data, size);
           if (ret < 0)
                   goto unlock;
   }

   ret = hid_report_raw_event(hid, type, data, size, interrupt);

The only return value that has any effect on the processing is
a negative error.

Correct this as it seems to confuse people: I found bogus code in
the Razer out-of-tree driver attempting to return 1 here.

Pull in a merge commit that brought in 3b692c55 ("HID: asus: only
support backlight when it's not driven by WMI") so that fixup could be
applied on top of it.

Due to what appears to be a copy/paste error, the opening ENTRY()
of cpu_v7_hvc_switch_mm() lacks a matching ENDPROC(), and instead,
the one for cpu_v7_smc_switch_mm() is duplicated.

Given that it is ENDPROC() that emits the Thumb annotation, the
cpu_v7_hvc_switch_mm() routine will be called in ARM mode on a
Thumb2 kernel, resulting in the following splat:

For non-zero return from dumpit() we should break the loop
in rtnl_dump_all() and return the result. Otherwise, e.g.,
we could get the memory leak in inet6_dump_fib() [1]. The
pointer to the allocated struct fib6_walker there (saved
in cb->args) can be lost, reset on the next iteration.

Fix it by partially restoring the previous behavior before
commit c63586dc ("net: rtnl_dump_all needs to propagate
error from dumpit function"). The returned error from
dumpit() is still passed further.

The __no_sanitize_address_or_inline and __no_kasan_or_inline defines
are almost identical. The only difference is that __no_kasan_or_inline
does not have the 'notrace' attribute.

To be able to replace __no_sanitize_address_or_inline with the older
definition, add 'notrace' to __no_kasan_or_inline and change to two
users of __no_sanitize_address_or_inline in the s390 code.

The 'notrace' option is necessary for e.g. the __load_psw_mask function
in arch/s390/include/asm/processor.h. Without the option it is possible
to trace __load_psw_mask which leads to kernel stack overflow.

The enet PHYs on imx6sx-sdb needs to be explicitly reset after a power
cycle, this can be handled by the phy-reset-gpios property. Sadly this
is not handled on suspend: the fec driver turns phy-supply off but
doesn't assert phy-reset-gpios again on resume.

Since additional phy-level work is required to support powering off the
phy in suspend fix the problem by just marking the regulator as
"boot-on" "always-on" so that it's never turned off. This behavior is
equivalent to older releases.

Keep the phy-reset-gpios property on fec anyway because it is a correct
description of board design.

This issue was exposed by commit efdfeb07 ("regulator: fixed:
Convert to use GPIO descriptor only") which causes the "gpios" property
to also be parsed. Before that commit the "gpios" property had no
effect, PHY reset was only handled in the the bootloader.

This fixes linux-next boot failures previously reported here:

A quoted label reference doesn't expand to the node path and is taken as
a literal string. Dropping the quotes can fix this unless the baudrate
string is appended in which case we have to use the alias.

At least on VF610, the problem was masked by setting the console in
bootargs. Use the alias syntax with baudrate parameter so we can drop
setting the console in bootargs.

Commit 4d2c0cda set slave->link to
BOND_LINK_DOWN for 802.3ad bonds whenever invalid speed/duplex values
were read, to fix a problem with slaves getting into weird states, but
in the process, broke tracking of link failures, as going straight to
BOND_LINK_DOWN when a link is indeed down (cable pulled, switch rebooted)
means we broke out of bond_miimon_inspect()'s BOND_LINK_DOWN case because
!link_state was already true, we never incremented commit, and never got
a chance to call bond_miimon_commit(), where slave->link_failure_count
would be incremented. I believe the simple fix here is to mark the slave
as BOND_LINK_FAIL, and let bond_miimon_inspect() transition the link from
_FAIL to either _UP or _DOWN, and in the latter case, we now get proper
incrementing of link_failure_count again.

Since 4.19 the following error in sysfs has appeared when using the
r8169 NIC driver:

$cd /sys/module/realtek/drivers
$ls -l
ls: cannot access 'mdio_bus:RTL8201F 10/100Mbps Ethernet': No such file or directory
[..garbled dir entries follow..]

Apparently the forward slash in "10/100Mbps Ethernet" is interpreted
as directory separator that leads nowhere, and was introduced in commit
513588dd ("net: phy: realtek: add RTL8201F phy-id and functions").

Fix this by removing the offending slash in the driver name.

Other drivers in net/phy seem to have the same problem, but I cannot
test/verify them.

If gcc decides not to inline make_sensor_label():

    WARNING: vmlinux.o(.text+0x4df549c): Section mismatch in reference from the function .create_device_attrs() to the function .init.text:.make_sensor_label()
    The function .create_device_attrs() references
    the function __init .make_sensor_label().
    This is often because .create_device_attrs lacks a __init
    annotation or the annotation of .make_sensor_label is wrong.

As .probe() can be called after freeing of __init memory, all __init
annotiations in the driver are bogus, and should be removed.
