ocfs2_page_mkwrite() could mistakenly return error code instead of
mkwrite status value. Fix it.

Functions which the compiler has instrumented for KASAN place poison on
the stack shadow upon entry and remove this poison prior to returning.
In the case of cpuidle, CPUs exit the kernel a number of levels deep in
C code. Any instrumented functions on this critical path will leave
portions of the stack shadow poisoned.
If CPUs lose context and return to the kernel via a cold path, we
restore a prior context saved in __cpu_suspend_enter are forgotten, and
we never remove the poison they placed in the stack shadow area by
functions calls between this and the actual exit of the kernel.
Thus, (depending on stackframe layout) subsequent calls to instrumented
functions may hit this stale poison, resulting in (spurious) KASAN
splats to the console.
To avoid this, clear any stale poison from the idle thread for a CPU
prior to bringing a CPU online.

Functions which the compiler has instrumented for KASAN place poison on
the stack shadow upon entry and remove this poision prior to returning.
In the case of CPU hotplug, CPUs exit the kernel a number of levels deep
in C code. Any instrumented functions on this critical path will leave
portions of the stack shadow poisoned.
When a CPU is subsequently brought back into the kernel via a different
path, depending on stackframe, layout calls to instrumented functions
may hit this stale poison, resulting in (spurious) KASAN splats to the
console.
To avoid this, clear any stale poison from the idle thread for a CPU
prior to bringing a CPU online.

Functions which the compiler has instrumented for ASAN place poison on
the stack shadow upon entry and remove this poison prior to returning.
In some cases (e.g. hotplug and idle), CPUs may exit the kernel a
number of levels deep in C code. If there are any instrumented
functions on this critical path, these will leave portions of the idle
thread stack shadow poisoned.
If a CPU returns to the kernel via a different path (e.g. a cold
entry), then depending on stack frame layout subsequent calls to
instrumented functions may use regions of the stack with stale poison,
resulting in (spurious) KASAN splats to the console.
Contemporary GCCs always add stack shadow poisoning when ASAN is
enabled, even when asked to not instrument a function [1], so we can't
simply annotate functions on the critical path to avoid poisoning.
Instead, this series explicitly removes any stale poison before it can
be hit. In the common hotplug case we clear the entire stack shadow in
common code, before a CPU is brought online.
On architectures which perform a cold return as part of cpu idle may
retain an architecture-specific amount of stack contents. To retain the
poison for this retained context, the arch code must call the core KASAN
code, passing a "watermark" stack pointer value beyond which shadow will
be cleared. Architectures which don't perform a cold return as part of
idle do not need any additional code.
This patch (of 3):
Functions which the compiler has instrumented for KASAN place poison on
the stack shadow upon entry and remove this poision prior to returning.
In some cases (e.g. hotplug and idle), CPUs may exit the kernel a number
of levels deep in C code. If there are any instrumented functions on this
critical path, these will leave portions of the stack shadow poisoned.
If a CPU returns to the kernel via a different path (e.g. a cold entry),
then depending on stack frame layout subsequent calls to instrumented
functions may use regions of the stack with stale poison, resulting in
(spurious) KASAN splats to the console.
To avoid this, we must clear stale poison from the stack prior to
instrumented functions being called. This patch adds functions to the
KASAN core for removing poison from (portions of) a task's stack. These
will be used by subsequent patches to avoid problems with hotplug and
idle.

The check for whether we overlap "System RAM" needs to be done at
section granularity. For example a system with the following mapping:
100000000-37bffffff : System RAM
37c000000-837ffffff : Persistent Memory
...is unable to use devm_memremap_pages() as it would result in two
zones colliding within a given section.

Given we have uninitialized list_heads being passed to list_add() it
will always be the case that those uninitialized values randomly trigger
the poison value. Especially since a list_add() operation will seed the
stack with the poison value for later stack allocations to trip over.
For example, see these two false positive reports:

Commit e1534ae95004 ("mm: differentiate page_mapped() from
page_mapcount() for compound pages") changed the famous
BUG_ON(page_mapped(page)) in __delete_from_page_cache() to
VM_BUG_ON_PAGE(page_mapped(page)): which gives us more info when
CONFIG_DEBUG_VM=y, but nothing at all when not.
Although it has not usually been very helpul, being hit long after the
error in question, we do need to know if it actually happens on users'
systems; but reinstating a crash there is likely to be opposed :)
In the non-debug case, pr_alert("BUG: Bad page cache") plus dump_page(),
dump_stack(), add_taint() - I don't really believe LOCKDEP_NOW_UNRELIABLE,
but that seems to be the standard procedure now. Move that, or the
VM_BUG_ON_PAGE(), up before the deletion from tree: so that the
unNULLified page->mapping gives a little more information.
If the inode is being evicted (rather than truncated), it won't have any
vmas left, so it's safe(ish) to assume that the raised mapcount is
erroneous, and we can discount it from page_count to avoid leaking the
page (I'm less worried by leaking the occasional 4kB, than losing a
potential 2MB page with each 4kB page leaked).

The warning message "killed due to inadequate hugepage pool" simply
indicates that SIGBUS was sent, not that the process was forcibly killed.
If the process has a signal handler installed does not fix the problem,
this message can rapidly spam the kernel log.
On my amd64 dev machine that does not have hugepages configured, I can
reproduce the repeated warnings easily by setting vm.nr_hugepages=2 (i.e.,
4 megabytes of huge pages) and running something that sets a signal
handler and forks, like
#include <sys/mman.h>
#include <signal.h>
#include <stdlib.h>
#include <unistd.h>
sig_atomic_t counter = 10;
void handler(int signal)
{
if (counter-- == 0)
exit(0);
}
int main(void)
{
int status;
char *addr = mmap(NULL, 4 * 1048576, PROT_READ | PROT_WRITE,
MAP_PRIVATE | MAP_ANONYMOUS | MAP_HUGETLB, -1, 0);
if (addr == MAP_FAILED) {perror("mmap"); return 1;}
*addr = 'x';
switch (fork()) {
case -1:
perror("fork"); return 1;
case 0:
signal(SIGBUS, handler);
*addr = 'x';
break;
default:
*addr = 'x';
wait(&status);
if (WIFSIGNALED(status)) {
psignal(WTERMSIG(status), "child");
}
break;
}
}

Pull sound fixes from Takashi Iwai:
"It's always an ambivalent feeling to send a large pull request at the
late stage like this, especially when most of patches came from me.
Anyway, this is a collection of lots of small fixes that slipped from
the previous pull request.
All fixes are about ASoC, and the majority of changes are corrections
of the wrong access types in ALSA ctl enum items. They are mostly
harmless on 32bit architectures, but actually buggy on 64bit. So we
addressed all these now in a shot. The rest are various small ASoC
driver fixes.
Among them, only two changes have been done to ASoC core, and both of
them are trivial. The rest are all device-specific. So overall, they
should be safe to apply"

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
ASoC: Fixes for v4.5
This is far too big a set of fixes for this late in the release cycle
but the overwhelming bulk is essentially the same simple fix from
Takashi for a cut'n'pasted 64 bit cleanliness issue in the userspace
interface where drivers were accessing things using the wrong element in
a union which worked OK on 32 bit platforms as the correct element
happened to be aligned the same way but with 64 bit platforms ABIs are
different and the two members of the union are laid out in different
places. They aren't all tagged to stable since some of these chips have
vanishingly little chance of being used in 64 bit systems.
The other changes are:
- A fix for Qualcomm devices to work on big endian systems. The
original change is actually correct but triggered a bug in regmap
which is too invasive to fix for this cycle and can be worked around
by just letting regmap pick the default.
- A fix for the Samsung I2S driver locking which wasn't using IRQ safe
spinlocks when it needed to.
- A fix for the new Intel Sky Lake driver forgetting that C pointer
arithmetic takes the type of the pointer into consideration.
- A revert of a change to the FSL SSI driver that broke some systems.
- A fix for the cleanup path of the wm9713 driver.
- A fix for some incorrect register definitions in the ADAU17x1 driver
that caused misclocking in some configurations.
- A fix for the tracepoints for jack detection to avoid using an
internal field of the core jack structure which is no longer present
in all configurations.
- A fix for another of the new Intel drivers which tried to write to a
string literal.

In the conversion to regmap, I assumed that the devm_() variant could be
used in the soc probe function.
As a mater of fact with the current code the regmap is freed twice

Fix this by replacing the devm_regmap initialization code with the non
devm_() variant.

Lockdep warns of a potential lock inversion, i2s->lock is held numerous
times whilst we are under the substream lock (snd_pcm_stream_lock). If
we use the IRQ unsafe spin lock calls, you can also end up locking
snd_pcm_stream_lock whilst under i2s->lock (if an IRQ happens whilst we
are holding i2s->lock). This could result in deadlock.

This reverts commit 18560a4e3 (ASoC: qcom: Specify LE device
endianness).
The commit that caused us to specify LE device endianness here,
29bb45f25ff3 (regmap-mmio: Use native endianness for read/write,
2015-10-29), has been reverted in mainline so now when we specify
LE it actively breaks big endian kernels because the byte
swapping in regmap-mmio is incorrect. Let's revert this change
because it will 1) fix the big endian kernels and 2) be redundant
to specify LE because that will become the default soon.

After a change to the snd_jack structure, the 'name' member
is no longer available in all configurations, which results in a
build failure in the tracing code:
include/trace/events/asoc.h: In function 'trace_event_raw_event_snd_soc_jack_report':
include/trace/events/asoc.h:240:32: error: 'struct snd_jack' has no member named 'name'
The name field is normally initialized from the card shortname and
the jack "id" field:
snprintf(jack->name, sizeof(jack->name), "%s %s",
card->shortname, jack->id);
This changes the tracing output to just contain the 'id' by
itself, which slightly changes the output format but avoids the
link error and is hopefully still enough to see what is going on.

We cannot use strcpy() to write to a const char * location. This is
causing a 'BUG: unable to handle kernel paging request' error at boot

codec_name of the wrong dai_link is being overwritten.

snd_soc_dapm_dai_link_get() and _put() access the associated ctl
values as value.integer.value[]. However, this is an enum ctl, and it
has to be accessed via value.enumerated.item[]. The former is long
while the latter is unsigned int, so they don't align.
