[ This resurrects commit 53855d10f456, which was reverted in
2b41226b39b6. It depended on commit d544abd5ff7d ("lib/radix-tree:
Convert to hotplug state machine") so now it is correct to apply ]
Patch "lib/radix-tree: Convert to hotplug state machine" breaks the test
suite as it adds a call to cpuhp_setup_state_nocalls() which is not
currently emulated in the test suite. Add it, and delete the emulation
of the old CPU hotplug mechanism.

Commit 34c3d9819fda ("genirq/affinity: Provide smarter irq spreading
infrastructure") introduced a better IRQ spreading mechanism, taking
account of the available NUMA nodes in the machine.
Problem is that the algorithm of retrieving the nodemask iterates
"linearly" based on the number of online nodes - some architectures
present non-linear node distribution among the nodemask, like PowerPC.
If this is the case, the algorithm lead to a wrong node count number
and therefore to a bad/incomplete IRQ affinity distribution.
For example, this problem were found in a machine with 128 CPUs and two
nodes, namely nodes 0 and 8 (instead of 0 and 1, if it was linearly
distributed). This led to a wrong affinity distribution which then led to
a bad mq allocation for nvme driver.
Finally, we take the opportunity to fix a comment regarding the affinity
distribution when we have _more_ nodes than vectors.

When the dummy timer callback is invoked before the real timer callbacks,
then it tries to install that timer for the starting CPU. If the platform
does not have a broadcast timer installed the installation fails with a
kernel crash. The crash happens due to a unconditional deference of the non
available broadcast device. This needs to be fixed in the timer core code.
But even when this is fixed in the core code then installing the dummy
timer before the real timers is a pointless exercise.
Move it to the end of the callback list.

Roland reported that his DELL T5810 sports a value add BIOS which
completely wreckages the TSC. The squirmware [(TM) Ingo Molnar] boots with
random negative TSC_ADJUST values, different on all CPUs. That renders the
TSC useless because the sycnchronization check fails.
Roland tested the new TSC_ADJUST mechanism. While it manages to readjust
the TSCs he needs to disable the TSC deadline timer, otherwise the machine
just stops booting.
Deeper investigation unearthed that the TSC deadline timer is sensitive to
the TSC_ADJUST value. Writing TSC_ADJUST to a negative value results in an
interrupt storm caused by the TSC deadline timer.
This does not make any sense and it's hard to imagine what kind of hardware
wreckage is behind that misfeature, but it's reliably reproducible on other
systems which have TSC_ADJUST and TSC deadline timer.
While it would be understandable that a big enough negative value which
moves the resulting TSC readout into the negative space could have the
described effect, this happens even with a adjust value of -1, which keeps
the TSC readout definitely in the positive space. The compare register for
the TSC deadline timer is set to a positive value larger than the TSC, but
despite not having reached the deadline the interrupt is raised
immediately. If this happens on the boot CPU, then the machine dies
silently because this setup happens before the NMI watchdog is armed.
Further experiments showed that any other adjustment of TSC_ADJUST works as
expected as long as it stays in the positive range. The direction of the
adjustment has no influence either. See the lkml link for further analysis.
Yet another proof for the theory that timers are designed by janitors and
the underlying (obviously undocumented) mechanisms which allow BIOSes to
wreckage them are considered a feature. Well done Intel - NOT!
To address this wreckage add the following sanity measures:
- If the TSC_ADJUST value on the boot cpu is not 0, set it to 0
- If the TSC_ADJUST value on any cpu is negative, set it to 0
- Prevent the cross package synchronization mechanism from setting negative
TSC_ADJUST values.

prefill_possible_map() reinitializes the cpu_possible_map by setting the
possible cpu bits and clearing all other bits up to NR_CPUS.
This is technically always correct because cpu_possible_map is statically
allocated and sized NR_CPUS. With CPUMASK_OFFSTACK and DEBUG_PER_CPU_MAPS
enabled the bounds check of cpu masks happens on nr_cpu_ids. nr_cpu_ids is
initialized to NR_CPUS and only limited after the set/clear bit loops have
been executed.
But if the system was booted with "nr_cpus=N" on the command line, where N
is < NR_CPUS then nr_cpu_ids is limited in the parameter parsing function
before prefill_possible_map() is invoked. As a consequence the cpumask
bounds check triggers when clearing the bits past nr_cpu_ids.
Add a helper which allows to reset cpu_possible_map w/o the bounds check
and then set only the possible bits which are well inside bounds.

When a server returns the optional flag SMB_SHARE_IS_IN_DFS in response
to a tree connect, cifs_build_path_to_root() will return a pathname
which includes the hostname. This causes problems with cifs_get_root()
which separates each component and does a lookup for each component of
the path which in this case will incorrectly include looking up the
hostname component as a path component.
We encountered a problem with dfs shares hosted by a Netapp. When
connecting to nodes pointed to by the DFS share. The tree connect for
these nodes return SMB_SHARE_IS_IN_DFS resulting failures in lookup
in cifs_get_root().

With commit 2b149f119 many things have been fixed/introduced.
However, the default behaviour for RawNTLMSSP authentication
seems to be wrong in case the domain is not passed on the command line.
The main points (see below) of the patch are:
- It alignes behaviour with Windows clients
- It fixes backward compatibility
- It fixes UPN
I compared this behavour with the one from a Windows 10 command line
client. When no domains are specified on the command line, I traced
the packets and observed that the client does send an empty
domain to the server.
In the linux kernel case, the empty domain is replaced by the
primary domain communicated by the SMB server.
This means that, if the credentials are valid against the local server
but that server is part of a domain, then the kernel module will
ask to authenticate against that domain and we will get LOGON failure.
I compared the packet trace from the smbclient when no domain is passed
and, in that case, a default domain from the client smb.conf is taken.
Apparently, connection succeeds anyway, because when the domain passed
is not valid (in my case WORKGROUP), then the local one is tried and
authentication succeeds. I tried with any kind of invalid domain and
the result was always a connection.
So, trying to interpret what to do and picking a valid domain if none
is passed, seems the wrong thing to do.
To this end, a new option "domainauto" has been added in case the
user wants a mechanism for guessing.
Without this patch, backward compatibility also is broken.
With kernel 3.10, the default auth mechanism was NTLM.
One of our testing servers accepted NTLM and, because no
domains are passed, authentication was local.
Moving to RawNTLMSSP forced us to change our command line
to add a fake domain to pass to prevent this mechanism to kick in.
For the same reasons, UPN is broken because the domain is specified
in the username.
The SMB server will work out the domain from the UPN and authenticate
against the right server.
Without the patch, though, given the domain is empty, it gets replaced
with another domain that could be the wrong one for the authentication.

dax-4.10-iomap-pmd topic branch from the XFS tree.
There is also a new direct IO implementation that uses the iomap
infrastructure. It's much simpler, faster, and has lower IO latency
than the existing direct IO infrastructure.
Summary:
- DAX PMD faults via iomap infrastructure
- Direct-io support in iomap infrastructure
- removal of now-redundant XFS inode iolock, replaced with VFS
i_rwsem
- synchronisation with fixes and changes in userspace libxfs code
- extent tree lookup helpers
- lots of little corruption detection improvements to verifiers
- optimised CRC calculations
- faster buffer cache lookups
- deprecation of barrier/nobarrier mount options - we always use
REQ_FUA/REQ_FLUSH where appropriate for data integrity now
- cleanups to speculative preallocation
- miscellaneous minor bug fixes and cleanups"

It actively hurts proper merging, and makes for a lot of special cases.
There was a good(ish) reason for doing it originally, but it's getting
too painful to maintain. And most of the original reasons for it are
long gone.
So instead of having special code to flush partial lines to the console
(as opposed to the record buffers), do _all_ the console writing from
the record buffer, and be done with it.
If an oops happens (or some other synchronous event), we will flush the
partial lines due to the oops printing activity, so this does not affect
that. It does mean that if you have a completely hung machine, a
partial preceding line may not have been printed out.
That was some of the original reason for this complexity, in fact, back
when we used to test for the historical i386 "halt" instruction problem
by doing
pr_info("Checking 'hlt' instruction... ");
if (!boot_cpu_data.hlt_works_ok) {
pr_cont("disabled\n");
return;
}
halt();
halt();
halt();
halt();
pr_cont("OK\n");
and that model no longer works (it the 'hlt' instruction kills the
machine, the partial line won't have been flushed, so you won't even see
it).
Of course, that was also back in the days when people actually had
textual console output rather than a graphical splash-screen at bootup.
How times change..

The record logging code looks at the previous record flags in various
ways, and they are all wrong.
You can't use the previous record flags to determine anything about the
next record, because they may simply not be related. In particular, the
reason the previous record was a continuation record may well be exactly
_because_ the new record was printed by a different process, which is
why the previous record was flushed.
So all those games are simply wrong, and make the code hard to
understand (because the code fundamentally cdoes not make sense).
So remove it.

These fields are 64 bit, using le32_to_cpu and friends
on these will not do the right thing.
Fix this up.
