The addition of the support for reading the temperature of ATA drives as
per commit 5b46903d8b ("hwmon: Driver for disk and solid state drives
with temperature sensors") lists in the respective Kconfig section the
name of the module to be optionally built as "satatemp".
However, building the kernel modules with "CONFIG_SENSORS_DRIVETEMP=m",
does not generate a file named "satatemp.ko".
Instead, the rest of the original commit uses the term "drivetemp" and
a file named "drivetemp.ko" ends up in the kernel's modules directory.
This file has the right ingredients:
$ strings /path/to/drivetemp.ko | grep ^description
description=Hard drive temperature monitor
and modprobing it produces the expected result:
# drivetemp is not loaded
$ sensors -u drivetemp-scsi-4-0
Specified sensor(s) not found!
$ sudo modprobe drivetemp
$ sensors -u drivetemp-scsi-4-0
drivetemp-scsi-4-0
Adapter: SCSI adapter
temp1:
temp1_input: 35.000
temp1_max: 60.000
temp1_min: 0.000
temp1_crit: 70.000
temp1_lcrit: -40.000
temp1_lowest: 20.000
temp1_highest: 36.000
Fix Kconfig by referring to the true name of the module.

This sorts the actual field names too, potentially causing even more
chaos and confusion at merge time if you have edited the MAINTAINERS
file. But the end result is a more consistent layout, and hopefully
it's a one-time pain minimized by doing this just before the -rc1
release.
This was entirely scripted:

They are all supposed to be sorted, but people who add new entries don't
always know the alphabet. Plus sometimes the entry names get edited,
and people don't then re-order the entry.
Let's see how painful this will be for merging purposes (the MAINTAINERS
file is often edited in various different trees), but Joe claims there's
relatively few patches in -next that touch this, and doing it just
before -rc1 is likely the best time. Fingers crossed.
This was scripted with
/scripts/parse-maintainers.pl --input=MAINTAINERS --output=MAINTAINERS
but then I also ended up manually upper-casing a few entry names that
stood out when looking at the end result.

detection feature.
It addressed the case where a KVM guest triggers a split lock #AC and KVM
reinjects it into the guest which is not prepared to handle it.
Adds proper sanity checks which prevent the unconditional injection into
the guest and handles the #AC on the host side in the same way as user
space detections are handled. Depending on the detection mode it either
warns and disables detection for the task or kills the task if the mode is
set to fatal.

It's a good idea to not read sqe->flags twice, as it's prone to security
bugs. Instead of passing it around, embeed them in req->flags. It's
already so except for IOSQE_IO_LINK.
1. rename former REQ_F_LINK -> REQ_F_LINK_HEAD
2. introduce and copy REQ_F_LINK, which mimics IO_IOSQE_LINK
And leave req_set_fail_links() using new REQ_F_LINK, because it's more

The mapping table may contain also ignore_ctl_error flag for devices
that are known to behave wild. Since this flag always writes the
card's own ignore_ctl_error flag, it overrides the value already set
by the module option, so it doesn't follow user's expectation.
Let's fix the code not to clear the flag that has been set by user.

The ignore_ctl_error option should filter the error at kctl accesses,
but there was an overlook: mixer_ctl_connector_get() returns an error
from the request.
This patch covers the forgotten code path and apply filter_error()
properly. The locking error is still returned since this is a fatal
error that has to be reported even with ignore_ctl_error option.

commit fcf1f59afc ("net: phy: marvell: rearrange to use
genphy_read_lpa()") moved the setting of phydev->duplex below the
phy_resolve_aneg_pause call. Due to a check of DUPLEX_FULL in that
function, phydev->pause was no longer set.
Fix it by moving the parsing of the status variable before the blocks
dealing with the pause frames.
As the Marvell 88E1510 datasheet does not specify the timing between the
link status and the "Speed and Duplex Resolved" bit, we have to force
the link down as long as the resolved bit is not set, to avoid reporting
link up before we even have valid Speed/Duplex.
Tested with a Marvell 88E1510 (RGMII to Copper/1000Base-T)

When oops happens with panic_on_oops unset, the oops
thread is killed by die() and system continues to run.
In such case, guest should not report crash register
data to host since system still runs. Check panic_on_oops
and return directly in hyperv_report_panic() when the function
is called in the die() and panic_on_oops is unset. Fix it.

We want to notify Hyper-V when a Linux guest VM crash occurs, so
there is a record of the crash even when kdump is enabled. But
crash_kexec_post_notifiers defaults to "false", so the kdump kernel
runs before the notifiers and Hyper-V never gets notified. Fix this by
always setting crash_kexec_post_notifiers to be true for Hyper-V VMs.

When a guest VM panics, Hyper-V should be notified only once via the
crash synthetic MSRs. Current Linux code might write these crash MSRs
twice during a system panic:
1) hyperv_panic/die_event() calling hyperv_report_panic()
2) hv_kmsg_dump() calling hyperv_report_panic_msg()
Fix this by not calling hyperv_report_panic() if a kmsg dump has been
successfully registered. The notification will happen later via
hyperv_report_panic_msg().

Two types of #AC can be generated in Intel CPUs:
1. legacy alignment check #AC
2. split lock #AC
Reflect #AC back into the guest if the guest has legacy alignment checks
enabled or if split lock detection is disabled.
If the #AC is not a legacy one and split lock detection is enabled, then
invoke handle_guest_split_lock() which will either warn and disable split
lock detection for this task or force SIGBUS on it.

Without at least minimal handling for split lock detection induced #AC,
VMX will just run into the same problem as the VMWare hypervisor, which
was reported by Kenneth.
It will inject the #AC blindly into the guest whether the guest is
prepared or not.
Provide a function for guest mode which acts depending on the host
SLD mode. If mode == sld_warn, treat it like user space, i.e. emit a
warning, disable SLD and mark the task accordingly. Otherwise force
SIGBUS.

Fix: Christoph Hellwig noticed that some logic I added to
orangefs_file_read_iter introduced a race condition, so he
sent a reversion patch. I had to modify his patch since
reverting at this point broke Orangefs.
Cleanup 1: Christoph Hellwig noticed that we were doing some unnecessary
work in orangefs_flush, so he sent in a patch that removed
the un-needed code.
Cleanup 2: Al Viro told me he had trouble building Orangefs. Orangefs
should be easy to build, even for Al :-). I looked back
at the test server build notes in orangefs.txt, just in case
that's where the trouble really is, and found a couple of
typos and made a couple of clarifications.
Merge Conflict: Stephen Rothwell reported that my modifications to
orangefs.txt caused a merge conflict with orangefs.rst
