This removes a bunch of core and elevator related code. On the core
front, we remove anything related to queue running, draining,
initialization, plugging, and congestions. We also kill anything
related to request allocation, merging, retrieval, and completion.
Remove any checking for single queue IO schedulers, as they no
longer exist. This means we can also delete a bunch of code related
to request issue, adding, completion, etc - and all the SQ related
ops and helpers.
Also kill the load_default_modules(), as all that did was provide
for a way to load the default single queue elevator.

Now that blk_flush_queue_rq() always returns false, we can
remove that return value. That bubbles through the stack,
allowing us to remove a bunch of state tracking around it.

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.

With drivers that are settting a virtual boundary constrain, we are
seeing a lot of bio splitting and smaller I/Os being submitted to the
driver.
This happens because the bio gap detection code does not account cases
where PAGE_SIZE - 1 is bigger than queue_virt_boundary() and thus will
split the bio unnecessarily.

There's a race between close_ctree() and cleaner_kthread().
close_ctree() sets btrfs_fs_closing(), and the cleaner stops when it
sees it set, but this is racy; the cleaner might have already checked
the bit and could be cleaning stuff. In particular, if it deletes unused
block groups, it will create delayed iputs for the free space cache
inodes. As of "btrfs: don't run delayed_iputs in commit", we're no
longer running delayed iputs after a commit. Therefore, if the cleaner
creates more delayed iputs after delayed iputs are run in
btrfs_commit_super(), we will leak inodes on unmount and get a busy
inode crash from the VFS.
Fix it by parking the cleaner before we actually close anything. Then,
any remaining delayed iputs will always be handled in
btrfs_commit_super(). This also ensures that the commit in close_ctree()
is really the last commit, so we can get rid of the commit in
cleaner_kthread().
The fstest/generic/475 followed by 476 can trigger a crash that
manifests as a slab corruption caused by accessing the freed kthread
structure by a wake up function. Sample trace:

The assignment of the feature flag NETIF_F_NTUPLE and NETIF_F_HW_TC
occurs prior to the initial setup of the local hw_features variable.
This means the features are set as user-changeable, but are not set in
the currently active feature list. This results in the features being
disabled at the driver's initial load.
Move the assignment after the initial assignment of hw_features, and
assign to the local variable. This ensures that NETIF_F_NTUPLE and
NETIF_F_HW_TC are marked as user-changeable, and also enables them by
default when the driver loads.

Since commit bacd75cfac8a ("i40e/i40evf: Add capability exchange for
outer checksum", 2017-04-06) the i40e driver has not reported support
for IP-in-IP offloads. This likely occurred due to a bad rebase, as the
commit extracts hw_enc_features into its own variable. As part of this
change, it dropped the NETIF_F_FSO_IPXIP flags from the
netdev->hw_enc_features. This was unfortunately not caught during code
review.
Fix this by adding back the missing feature flags.
For reference, NETIF_F_GSO_IPXIP4 was added in commit 7e13318daa4a
("net: define gso types for IPx over IPv4 and IPv6", 2016-05-20),
replacing NETIF_F_GSO_IPIP and NETIF_F_GSO_SIT.

Fix an issue with the 32-bit range error path in `rtc_hctosys' where no
error code is set and consequently the successful preceding call result
from `rtc_read_time' is propagated to `rtc_hctosys_ret'. This in turn
makes any subsequent call to `hctosys_show' incorrectly report in sysfs
that the system time has been set from this RTC while it has not.
Set the error to ERANGE then if we can't express the result due to an
overflow.

When there is no IRQ configured for the RTC, the rtc-cmos code does not
support alarms, all alarm rtc_ops fail with -EIO / -EINVAL.
The rtc-core expects a rtc driver which does not support rtc alarms to
not have alarm ops at all. Otherwise the wakealarm sysfs attr will read
as empty rather then returning an error, making it impossible for
userspace to find out beforehand if alarms are supported.
A system without an IRQ for the RTC before this patch:
[root@localhost ~]# cat /sys/class/rtc/rtc0/wakealarm
[root@localhost ~]#
After this patch:
[root@localhost ~]# cat /sys/class/rtc/rtc0/wakealarm
cat: /sys/class/rtc/rtc0/wakealarm: No such file or directory
[root@localhost ~]#
This fixes gnome-session + systemd trying to use suspend-then-hibernate,
which causes systemd to abort the suspend when writing the RTC alarm fails.

SLIM_MSG_CLK_PAUSE_SEQ_FLG is never set in any of the slim core,
so performing a check in ngd driver is totally unnecessary.
Also this patch fixes warning about mc field overflow reported
with CoverityScan.
Making clk pause feature optional will be added to slim core in
next development cycle.

The order in which the frequencies are displayed in cpufreq stats
depends on the order in which the frequencies were sorted in the
frequency table provided to cpufreq core by the cpufreq driver. They can
be completely unsorted as well.
The documentation's claim that the stats will be sorted in descending
order is hence incorrect and here is an attempt to fix it.

Raydium USB touchscreen fails to set config if LPM is enabled:
[ 2.030658] usb 1-8: New USB device found, idVendor=2386, idProduct=3119
[ 2.030659] usb 1-8: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[ 2.030660] usb 1-8: Product: Raydium Touch System
[ 2.030661] usb 1-8: Manufacturer: Raydium Corporation
[ 7.132209] usb 1-8: can't set config #1, error -110
Same behavior can be observed on 2386:3114.
Raydium claims the touchscreen supports LPM under Windows, so I used
Microsoft USB Test Tools (MUTT) [1] to check its LPM status. MUTT shows
that the LPM doesn't work under Windows, either. So let's just disable LPM
for Raydium touchscreens.
