git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm updates from Dan Williams:
- Replace pcommit with ADR / directed-flushing.
The pcommit instruction, which has not shipped on any product, is
deprecated. Instead, the requirement is that platforms implement
either ADR, or provide one or more flush addresses per nvdimm.
ADR (Asynchronous DRAM Refresh) flushes data in posted write buffers
to the memory controller on a power-fail event.
Flush addresses are defined in ACPI 6.x as an NVDIMM Firmware
Interface Table (NFIT) sub-structure: "Flush Hint Address Structure".
A flush hint is an mmio address that when written and fenced assures
that all previous posted writes targeting a given dimm have been
flushed to media.
- On-demand ARS (address range scrub).
Linux uses the results of the ACPI ARS commands to track bad blocks
in pmem devices. When latent errors are detected we re-scrub the
media to refresh the bad block list, userspace can also request a
re-scrub at any time.
- Support for the Microsoft DSM (device specific method) command
format.
- Support for EDK2/OVMF virtual disk device memory ranges.
- Various fixes and cleanups across the subsystem.

When a latent (unknown to 'badblocks') error is encountered, it will
trigger a machine check exception. On a system with machine check
recovery, this will only SIGBUS the process(es) which had the bad page
mapped (as opposed to a kernel panic on platforms without machine
check recovery features). In the former case, we want to trigger a full
rescan of that nvdimm bus. This will allow any additional, new errors
to be captured in the block devices' badblocks lists, and offending
operations on them can be trapped early, avoiding machine checks.
This is done by registering a callback function with the
x86_mce_decoder_chain and calling the new ars_rescan functionality with
the address in the mce notificatiion.

PROT_SAO is a powerpc-specific flag to mmap(), and we rely on arch
specific logic to allow it to be passed to mmap().
Add a small test to ensure mmap() accepts PROT_SAO. We don't have a good
way to test that it actually causes the mapping to be created with the
right flags, so for now we just touch the mapping so it's faulted in. In
future we might be able to do something better.

Currently it doesn't appear the resulting binary actually uses any
Altivec or VSX instructions the solution is to explicitly tell GCC to
use vector instructions and use vector types in the code.
Part of this this issue can be GCC version specific:
GCC 4.9.x is happy to use Altivec and VSX instructions if altivec.h is
includedi (and possibly if vector types are used), this also means that
4.9.x will use VSX instructions even if only -maltivec is passed. It is
also possible that Altivec instructions will be used even without
-maltivec or -mabi=altivec.
GCC 5.2.x complains about the lack of -maltivec parameter if altivec.h
is included and will not use VSX unless -mvsx is present on commandline.
GCC 5.3.0 has a regression that means __attribute__((__target__("no-vsx"))
fails to build. A fix is targeted for 5.4.
Furthermore LTO (Link Time Optimisation) doesn't play well with
__attribute__((__target__("no-vsx")), LTO can cause GCC to forget about
the attribute and compile with VSX instructions regardless. Be wary when
enabling -flfo for this test.

Excerpt from man 2 perf_event_open:
/proc/sys/kernel/perf_event_paranoid
The perf_event_paranoid file can be set to restrict access to the
performance counters.
2 allow only user-space measurements.
1 allow both kernel and user measurements (default).
0 allow access to CPU-specific data but not raw tracepoint samples.
-1 no restrictions.
require_paranoia_below() should return 0 if perf_event_paranoid is below
a specified level, the value from perf_event_paranoid is read into an
unsigned long so the incorrect value is returned when
perf_event_paranoid is set to -1.
Without this patch applied there is the same number of selftests/powerpc
which skip when /proc/sys/kernel/perf_event_paranoid is set to 1 or -1
but no skips when set to zero.
With this patch applied there are no skipped selftests/powerpc test when
/proc/sys/kernel/perf_event_paranoid is set to 0 or -1.

For old style drivers, call a call to ioctl(..., RTC_ALM_SET, ...):
- char/ds1302.c will always return -EINVAL
- char/genrtc.c: will always return -EINVAL
- char/rtc.c will succeed regardless if IRQs are supported or not
- char/efirtc.c will always return -EINVAL
- input/misc/hp_sdc_rtc.c ... that ioctl code is a good lesson about
ifdefing code out and punting implementation ... and it will
always return -EINVAL
For new style rtc drivers, a call to ioctl(..., RTC_ALM_SET, ...) never
results in a call to __rtc_set_alarm, since struct rtc_wkalarm passed to
rtc_set_alarm has 'enabled' field set to 0. This means that
rtc->ops->set_alarm driver hook is never called in that ioctl. Since no
driver code interaction happens as a part of that call, using its
results to ascertain properties of the driver is not going to work. To
remedy this - use the result of RTC_AIE_ON to make the judgement.
This patch also changes ENOTTY to EINVAL as an error code value that
would tell us that IRQs are not supported. There are three reason for
this:
- As mentioned above old style driver never returns ENOTTY for this
ioctl
- In it's code __rtc_set_alarm() returns -EINVAL if rtc->ops->set_alarm
method is not provided by the driver, so one reason for change is to
be consistent with that code path.
- A call to ioctl(..., RTC_UIE_ON, ...) will result in a call to
rtc_update_irq_enable() and then __rtc_set_alarm(), which, if IRQs
are not supported by the driver, will result in a non-zero error
code. Returning ENOTTY in that case would:
a) Not be consistent with other codepaths of
rtc_update_irq_enable, for example the check of
rtc->uie_unsupported
b) Would break update IRQ emulation code since that codpath
expects EINVAL
c) Would break test's logic for feature support detection in
the case of RTC_UIE_ON ioctl

we want to enable nfit_test to operate without DMA_CMA and the pmem it

of supporting direct_access requests larger than a page. Make

When histograms are not configured in the kernel, the ftracetest histogram
selftests should return "unsupported" and not "Failed". To detect this, the
test scripts have:
FEATURE=`grep hist events/sched/sched_process_fork/trigger`
if [ -z "$FEATURE" ]; then
echo "hist trigger is not supported"
exit_unsupported
fi
The problem is that '-e' is in effect and any error will cause the program
to terminate. The grep for 'hist' fails, because it is not compiled it (thus
unsupported), but because grep has an error code for failing to find the
string, it causes the program to terminate, and is marked as a failed test.
Namhyung Kim recommended to test for the "hist" file located in
events/sched/sched_process_fork/hist instead, as it is more inline with the
other checks. As the hist file is only created if the histogram feature is
enabled, that is a valid check.
