Pull IPMI updates from Corey Minyard:
"Remove some old cruft that was disabled by default a long time ago.
No modern hardware should need this, and anybody who really doesn't
have something to automatically detect IPMI can add the device by hand
on the module commandline or hot add it"

Several build configurations had already disabled this warning because
it generates a lot of false positives. But some had not, and it was
still enabled for "allmodconfig" builds, for example.
Looking at the warnings produced, every single one I looked at was a
false positive, and the warnings are frequent enough (and big enough)
that they can easily hide real problems that you don't notice in the
noise generated by -Wmaybe-uninitialized.
The warning is good in theory, but this is a classic case of a warning
that causes more problems than the warning can solve.
If gcc gets better at avoiding false positives, we may be able to
re-enable this warning. But as is, we're better off without it, and I
want to be able to see the *real* warnings.

Because it uses that function, which would lead every tool using it
to need to link against tools/lib/str_error_r.o.
This fixes building tools/vm/, that links with libapi.

Pull f2fs updates from Jaegeuk Kim:
"The major change in this version is mitigating cpu overheads on write
paths by replacing redundant inode page updates with mark_inode_dirty
calls. And we tried to reduce lock contentions as well to improve
filesystem scalability. Other feature is setting F2FS automatically
when detecting host-managed SMR.
Enhancements:
- ioctl to move a range of data between files
- inject orphan inode errors
- avoid flush commands congestion
- support lazytime
Bug fixes:
- return proper results for some dentry operations
- fix deadlock in add_link failure
- disable extent_cache for fcollapse/finsert"

git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs
Pull xfs updates from Dave Chinner:
"The major addition is the new iomap based block mapping
infrastructure. We've been kicking this about locally for years, but
there are other filesystems want to use it too (e.g. gfs2). Now it
is fully working, reviewed and ready for merge and be used by other
filesystems.
There are a lot of other fixes and cleanups in the tree, but those are
XFS internal things and none are of the scale or visibility of the
iomap changes. See below for details.
I am likely to send another pull request next week - we're just about
ready to merge some new functionality (on disk block->owner reverse
mapping infrastructure), but that's a huge chunk of code (74 files
changed, 7283 insertions(+), 1114 deletions(-)) so I'm keeping that
separate to all the "normal" pull request changes so they don't get
lost in the noise.
Summary of changes in this update:
- generic iomap based IO path infrastructure
- generic iomap based fiemap implementation
- xfs iomap based Io path implementation
- buffer error handling fixes
- tracking of in flight buffer IO for unmount serialisation
- direct IO and DAX io path separation and simplification
- shortform directory format definition changes for wider platform
compatibility
- various buffer cache fixes
- cleanups in preparation for rmap merge
- error injection cleanups and fixes
- log item format buffer memory allocation restructuring to prevent
rare OOM reclaim deadlocks
- sparse inode chunks are now fully supported"

Parameter trydefaults=1 causes the ipmi_init to initialize ipmi through
the legacy port io space that was designated for ipmi. Architectures
that do not map legacy port io can panic when trydefaults=1.
Rather than implement build-time conditional exceptions for each
architecture that does not map legacy port io, we have removed legacy
port io from the driver.
Parameter 'trydefaults' has been removed. Attempts to use it hereafter
will evoke the "Unknown symbol in module, or unknown parameter" message.
The patch was built against a number of architectures and tested for
regressions and functionality on x86_64 and ARM64.

Suppose that stop_machine(fn) hangs because fn() hangs. In this case NMI
hard-lockup can be triggered on another CPU which does nothing wrong and
the trace from nmi_panic() won't help to investigate the problem.
And this change "fixes" the problem we (seem to) hit in practice.
- stop_two_cpus(0, 1) races with show_state_filter() running on CPU_0.
- CPU_1 already spins in MULTI_STOP_PREPARE state, it detects the soft
lockup and tries to report the problem.
- show_state_filter() enables preemption, CPU_0 calls multi_cpu_stop()
which goes to MULTI_STOP_DISABLE_IRQ state and disables interrupts.
- CPU_1 spends more than 10 seconds trying to flush the log buffer to
the slow serial console.
- NMI interrupt on CPU_0 (which now waits for CPU_1) calls nmi_panic().

Setting TS_COMPAT in ptrace is wrong: if we happen to do it during
syscall entry, then we'll confuse seccomp and audit. (The former
isn't a security problem: seccomp is currently entirely insecure if a
malicious ptracer is attached.) As a minimal fix, this patch adds a
new flag TS_I386_REGS_POKED that handles the ptrace special case.

The newly added Kconfig option could never work and just causes a build error
when disabled:

bool aa_g_hash_policy = CONFIG_SECURITY_APPARMOR_HASH_DEFAULT;
The problem is that the macro undefined in this case, and we need to use the IS_ENABLED()
helper to turn it into a boolean constant.
Another minor problem with the original patch is that the option is even offered
in sysfs when SECURITY_APPARMOR_HASH is not enabled, so this also hides the option
in that case.

The be2net driver performs fw temperature queries on be_worker() routine,
which is executed each second for each be_adapter. There is a frequency
threshold to avoid fw query to happens at each call to be_worker();
instead, currently a fw query occurs once in 64 runs of the procedure.
Nevertheless, this fw temperature query is invoked only for adapters which
interface is up, so we can see I/O errors on read of hwmon counters from
userspace (from tools like lm-sensors) in case we have adapters' functions
which interface is down.
This patch moves the fw query code to be invoked even if interface is down.
No functional changes were introduced.

If an EEH or some other hard error occurs while the adapter instance was
being initialized, on the subsequent shutdown of the device, the system
could crash with:

As a fix, shutdown notification should only occur when the AFU is

The lpfc_sli4_scmd_to_wqidx_distr() function expects the scsi_cmnd
'lpfc_cmd->pCmd' not to be null, and point to the midlayer command.
That's not true in the .eh_(device|target|bus)_reset_handler path,
because lpfc_send_taskmgmt() sends commands not from the midlayer, so
does not set 'lpfc_cmd->pCmd'.
That is true in the .queuecommand path because lpfc_queuecommand()
stores the scsi_cmnd from midlayer in lpfc_cmd->pCmd; and lpfc_cmd is
stored by lpfc_scsi_prep_cmnd() in piocbq->context1 -- which is passed
to lpfc_sli4_scmd_to_wqidx_distr() as lpfc_cmd parameter.
This problem can be hit on SCSI EH, and immediately with sg_reset.

Signing a module should only make it trusted by the specific kernel it
was built for, not anything else. If a module signing key is used for
multiple ABI-incompatible kernels, the modules need to include enough
version information to distinguish them.

Signing a module should only make it trusted by the specific kernel it
was built for, not anything else. Loading a signed module meant for a
kernel with a different ABI could have interesting effects.
Therefore, treat all signatures as invalid when a module is
force-loaded.

While most of the locations where a kernel taint bit is set are accompanied
with a warning message, there are two which set their bits silently. If
the tainting module gets unloaded later on, it is almost impossible to tell
what was the reason for setting the flag.

__module_put_and_exit() is makred noreturn in module.h declaration, but is
lacking the attribute in the definition, which makes some tools (such as
sparse) unhappy. Amend the definition with the attribute as well (and
reformat the declaration so that it uses more common format).

Update the hvc driver to use the OPAL irqchip if made available by the
running firmware. If it is not present, the driver falls back to the
existing OPAL event number.

Commit 2def86a7200c ("hvc: Convert to using interrupts instead of opal
events") enabled the use of interrupts in the hvc_driver for OPAL
platforms. However on machines with more than one hvc console, any
console after the first will fail to register an interrupt handler in
notifier_add_irq() since all consoles share the same IRQ number but do
not set the IRQF_SHARED flag:
genirq: Flags mismatch irq 31. 00000000 (hvc_console) vs. 00000000 (hvc_console)
hvc_open: request_irq failed with rc -16.
This error propagates up to hvc_open() and the console is closed, but
OPAL will still generate interrupts that are not handled, leading to
rcu_sched stall warnings.
Set IRQF_SHARED when calling request_irq(), allowing additional consoles
to start properly. This is only set for consoles handled by
hvc_opal_probe(), leaving other types unaffected.
