by making sure we call iov_iter_advance() on original
iov_iter even if direct_IO (done on its copy) has returned 0.
It's a no-op for old iov_iter flavours and does the right thing
(== truncation of the stuff we'd allocated, but not filled) in
ITER_PIPE case. Failures (e.g. -EIO) get caught and dealt with
by cleanup in generic_file_read_iter().

Merge my system logging cleanups, triggered by the broken '\n' patches.
The line continuation handling has been broken basically forever, and
the code to handle the system log records was both confusing and
dubious. And it would do entirely the wrong thing unless you always had
a terminating newline, partly because it couldn't actually see whether a
message was marked KERN_CONT or not (but partly because the LOG_CONT
handling in the recording code was rather confusing too).
This re-introduces a real semantically meaningful KERN_CONT, and fixes
the few places I noticed where it was missing. There are probably more
missing cases, since KERN_CONT hasn't actually had any semantic meaning
for at least four years (other than the checkpatch meaning of "no log
level necessary, this is a continuation line").
This also allows the combination of KERN_CONT and a log level. In that
case the log level will be ignored if the merging with a previous line
is successful, but if a new record is needed, that new record will now
get the right log level.
That also means that you can at least in theory combine KERN_CONT with
the "pr_info()" style helpers, although any use of pr_fmt() prefixing
would make that just result in a mess, of course (the prefix would end
up in the middle of a continuing line).
* printk-cleanups:
printk: make reading the kernel log flush pending lines
printk: re-organize log_output() to be more legible
printk: split out core logging code into helper function
printk: reinstate KERN_CONT for printing continuation lines
After backporting commit ee44b4bc05 ("dlm: use sctp 1-to-1 API")
series to a kernel with an older workqueue which didn't use RCU yet, it
was noticed that we are freeing the workqueues in dlm_lowcomms_stop()
too early as free_conn() will try to access that memory for canceling
the queued works if any.
This issue was introduced by commit 0d737a8cfd as before it such
attempt to cancel the queued works wasn't performed, so the issue was
not present.
This patch fixes it by simply inverting the free order.

That will mean that any possible subsequent continuation will now be
broken up onto a line of its own (since reading the log has finalized
the beginning og the line), but if user space has activated system
logging (or if there's a kernel message dump going on) that is the right
thing to do.
And now that we actually get the continuation flags _right_ for this
all, the user space logger that is reading the kernel messages can
actually see the continuation marker. Not that anybody seems to really
bother with it (or care), but in theory user space can do its own
message stitching.

Avoid some duplicate logic now that we can return early, and update the
comments for the new LOG_CONT world order.
This also stops the continuation flushing from just using random record
flags for the flushing action, instead taking the flags from the proper
original line and updating them as we add continuations to it.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
The code that actually decides how to log the message (whether to put it
directly into the record log, whether to append it to an existing
buffered log, or whether to start a new buffered log) is fairly
non-obvious code in the middle of the vprintk_emit() function.
Splitting that code up into a helper function makes it easier to
understand, but perhaps more importantly also allows for the code to
just return early out of the helper function once it has made the
decision about where the new log content goes.

Long long ago the kernel log buffer was a buffered stream of bytes, very
much like stdio in user space. It supported log levels by scanning the
stream and noticing the log level markers at the beginning of each line,
but if you wanted to print a partial line in multiple chunks, you just
did multiple printk() calls, and it just automatically worked.
Except when it didn't, and you had very confusing output when different
lines got all mixed up with each other. Then you got fragment lines
mixing with each other, or with non-fragment lines, because it was
traditionally impossible to tell whether a printk() call was a
continuation or not.
To at least help clarify the issue of continuation lines, we added a
KERN_CONT marker back in 2007 to mark continuation lines:
4749252776 ("printk: add KERN_CONT annotation").
That continuation marker was initially an empty string, and didn't
actuall make any semantic difference. But it at least made it possible
to annotate the source code, and have check-patch notice that a printk()
didn't need or want a log level marker, because it was a continuation of
a previous line.
To avoid the ambiguity between a continuation line that had that
KERN_CONT marker, and a printk with no level information at all, we then
in 2009 made KERN_CONT be a real log level marker which meant that we
could now reliably tell the difference between the two cases.
5fd29d6ccb ("printk: clean up handling of log-levels and newlines")
and we could take advantage of that to make sure we didn't mix up
continuation lines with lines that just didn't have any loglevel at all.
Then, in 2012, the kernel log buffer was changed to be a "record" based
log, where each line was a record that has a loglevel and a timestamp.
You can see the beginning of that conversion in commits
e11fea92e1 ("kmsg: export printk records to the /dev/kmsg interface")
7ff9554bb5 ("printk: convert byte-buffer to variable-length record buffer")
with a number of follow-up commits to fix some painful fallout from that
conversion. Over all, it took a couple of months to sort out most of
it. But the upside was that you could have concurrent readers (and
writers) of the kernel log and not have lines with mixed output in them.
And one particular pain-point for the record-based kernel logging was
exactly the fragmentary lines that are generated in smaller chunks. In
order to still log them as one recrod, the continuation lines need to be
attached to the previous record properly.
However the explicit continuation record marker that is actually useful
for this exact case was actually removed in aroundm the same time by commit
61e99ab8e3 ("printk: remove the now unnecessary "C" annotation for KERN_CONT")
due to the incorrect belief that KERN_CONT wasn't meaningful. The
ambiguity between "is this a continuation line" or "is this a plain
printk with no log level information" was reintroduced, and in fact
became an even bigger pain point because there was now the whole
record-level merging of kernel messages going on.
This patch reinstates the KERN_CONT as a real non-empty string marker,
so that the ambiguity is fixed once again.
But it's not a plain revert of that original removal: in the four years
since we made KERN_CONT an empty string again, not only has the format
of the log level markers changed, we've also had some usage changes in
this area.
For example, some ACPI code seems to use KERN_CONT _together_ with a log
level, and now uses both the KERN_CONT marker and (for example) a
KERN_INFO marker to show that it's an informational continuation of a
line.
Which is actually not a bad idea - if the continuation line cannot be
attached to its predecessor, without the log level information we don't
know what log level to assign to it (and we traditionally just assigned
it the default loglevel). So having both a log level and the KERN_CONT
marker is not necessarily a bad idea, but it does mean that we need to
actually iterate over potentially multiple markers, rather than just a
single one.
Also, since KERN_CONT was still conceptually needed, and encouraged, but
didn't actually _do_ anything, we've also had the reverse problem:
rather than having too many annotations it has too few, and there is bit
rot with code that no longer marks the continuation lines with the
KERN_CONT marker.
So this patch not only re-instates the non-empty KERN_CONT marker, it
also fixes up the cases of bit-rot I noticed in my own logs.
There are probably other cases where KERN_CONT will be needed to be
added, either because it is new code that never dealt with the need for
KERN_CONT, or old code that has bitrotted without anybody noticing.
That said, we should strive to avoid the need for KERN_CONT. It does
result in real problems for logging, and should generally not be seen as
a good feature. If we some day can get rid of the feature entirely,
because nobody does any fragmented printk calls, that would be lovely.
But until that point, let's at mark the code that relies on the hacky
multi-fragment kernel printk's. Not only does it avoid the ambiguity,
it also annotates code as "maybe this would be good to fix some day".
(That said, particularly during single-threaded bootup, the downsides of
KERN_CONT are very limited. Things get much hairier when you have
multiple threads going on and user level reading and writing logs too).

Our XSAVE features are divided into two categories: those that
generate FPU exceptions, and those that do not. MPX and pkeys do
not generate FPU exceptions and thus can not be used lazily. We
disable them when lazy mode is forced on.
We have a pair of masks to collect these two sets of features, but
XFEATURE_MASK_PKRU was added to the wrong mask: XFEATURE_MASK_LAZY.
Fix it by moving the feature to XFEATURE_MASK_EAGER.
Note: this only causes problem if you boot with lazy FPU mode
(eagerfpu=off) which is *not* the default. It also only affects
hardware which is not currently publicly available. It looks like
eager mode is going away, but we still need this patch applied
to any kernel that has protection keys and lazy mode, which is 4.6
through 4.8 at this point, and 4.9 if the lazy removal isn't sent
to Linus for 4.9.

Markus reported that he sees new warnings:
APIC: NR_CPUS/possible_cpus limit of 4 reached. Processor 4/0x84 ignored.
APIC: NR_CPUS/possible_cpus limit of 4 reached. Processor 5/0x85 ignored.
This comes from the recent persistant cpuid - nodeid changes. The code
which emits the warning has been called prior to these changes only for
enabled processors. Now it's called for disabled processors as well to get
the possible cpu accounting correct. So if the kernel is compiled for the
number of actual available/enabled CPUs and the BIOS reports disabled CPUs
as well then the above warnings are printed.
That's a pointless exercise as it only makes sense if there are more CPUs
enabled than the kernel supports.
Nake the warning conditional on enabled processors so we are back to the
state before these changes.

Yinghai reported that the recent changes to make the cpuid - nodeid
relationship permanent causes a cpuid ordering regression on a system which
has 2apic enabled..
The reason is that the ACPI local APIC parser has no sanity check for
apicid 0xff, which is an invalid id. So a CPU id for this invalid local
APIC id is allocated and therefor breaks the cpuid ordering.
Add a sanity check to acpi_parse_lapic() which ignores the invalid id.

Pull ARM 64-bit DT updates from Arnd Bergmann:
"The 64-bit DT changes are surprisingly small this time, we only add
two SoC platforms: the ZTE ZX296718 Set-top-box SoC and the SocioNext
UniPhier LD11 TV SoC, each with their reference boards.
There are three new machines added for existing SoC platforms:
- The Marvell Armada 8040 development board is an impressive
quad-core Cortex-A72 machine with three 10gbit ethernet interfaces
- Qualcomms DragonBoard 820c single-board computer is their current
high-end phone platform in the 96boards form factor
- Rockchip: Tronsmart Orion r86 set-top-box is a popular mid-range
Android box based on the 8-core rk3368 SoC"

These are as usual a very large number of mostly boring updates to
enable devices in existing machines, or to fix minor bugs. Notably,
an ongoing treewide effort to fix warnings caused by an update to the
device tree compiler. These are enabled with "make W=1" at the moment
but can hopefully become the default once all issues have been addressed.

mv88f5181 are slight variations of existing ones), but a significant
number of new dts files are added, which I list by platform:

both of which already have 32-bit support in arch/arm:

presumably the respective dts files and more information will
follow at a later point.
- The ZTE ZX296718 SoC for set-top-boxes, a relative of the 32-bit
ZX296702 SoC that we already support.

These are updates for platform specific code on 32-bit ARM machines,
essentially anything that can not (yet) be expressed using DT files.
Noteworthy changes include:
- We get support for running in big-endian mode on two platforms:
sunxi (Allwinner) and s3c24xx (old Samsung).
- The recently added Uniphier platform now uses standard PSCI
methods for SMP booting and we remove support for old bootloader
versions that did not support it yet.
- In sunxi, we gain support for the "Nextthing GR8" SoC, which
is a close relative of the Allwinner A13 and R8 chips.
- PXA completes its move over to the generic dmaengine framework
and removes its old private API
- mach-bcm gains support for BCM47189/BCM53573, their first ARM
SoC with integrated 802.11ac wireless networking.

The cleanups for v4.9 are a little larger that usual, but thankfully
that is almost exclusively due to removing a significant number of
files that have become obsolete after the still ongoing conversion
of old board files to devicetree.
- for mach-omap2, which is still the largest platform in arch/arm/,
the conversion to DT is finally complete after the Nokia N900 is
now fully supported there, along with the omap3 LDP, and we can
remove those two board files.
If no regressions are found, another large cleanup for the platform
will happen as a follow-up, removing dead code and restructuring
the platform based on being DT-only.
- In mach-imx, similar work is ongoing, but has not come that far.
This time, we remove the obsolete board file for the i.MX1
generation, which like i.MX25, i.MX5, i.MX6, and i.MX7 is now DT-only.
The remaining board files are for i.MX2 and i.MX3 machines
based on old ARM926 or ARM1136 cores that should work with DT
in principle.
- realview has just been converted from board files to DT, and a lot
of code gets removed in the process. This is the last
ARM/Keil/Versatile derived platform that was still using board
files, the other ones being integrator, versatile and vexpress.
We can probably merge the remaining code into a single directory
in the near future.
- clps711x had completed the conversion in v4.8, but we accidentally
left the files in place that should have been deleted then.
Conflicts: two files deleted here have been modified upstream,
the changes can be discarded.
