turbostat gives valid results across suspend to idle, aka freeze,
whether invoked in  interval mode, or in command mode.
Indeed, this can be used to measure suspend to idle:

turbostat echo freeze > /sys/power/state

But this does not work across suspend to ACPI S3, because the
processor counters, including the TSC, are reset on resume.
Further, when turbostat detects a problem, it does't forgive
the hardware, and interval mode will print *'s from there on out.

Instead, upon detecting counters going backwards, simply
reset and start over.

Interval mode across ACPI S3: (observe TSC going backwards)

The RAPL Joules counter is limited in capacity.
Turbostat estimates how soon it can roll-over
based on the max TDP of the processor --
which tells us the maximum increment rate.

eg.
RAPL: 2759 sec. Joule Counter Range, at 95 Watts

So if a sample duration is longer than 2759 seconds on this system,
'**' replace the decimal place in the display to indicate
that the results may be suspect.

But the display had an extra ' ' in this case, throwing off the columns.

Also, the -J "Joules" option appended an extra "time" column
to the display.  While this may be useful, it printed the interval time,
which may not be the accurate time per processor.  Remove this column,
which appeared only when using '-J',
as we plan to add accurate per-cpu interval times in a future commit.

Merge misc fixes from Andrew Morton:

* emailed patches from Andrew Morton <akpm@linux-foundation.org>:
  mm: fix false-positive WARN_ON() in truncate/invalidate for hugetlb
  kasan: support use-after-scope detection
  kasan: update kasan_global for gcc 7
  lib/debugobjects: export for use in modules
  zram: fix unbalanced idr management at hot removal
  thp: fix corner case of munlock() of PTE-mapped THPs
  mm, thp: propagation of conditional compilation in khugepaged.c

Hugetlb pages have ->index in size of the huge pages (PMD_SIZE or
PUD_SIZE), not in PAGE_SIZE as other types of pages.  This means we
cannot user page_to_pgoff() to check whether we've got the right page
for the radix-tree index.

Let's introduce page_to_index() which would return radix-tree index for
given page.

We will be able to get rid of this once hugetlb will be switched to
multi-order entries.

Drivers, or other modules, that use a mixture of objects (especially

the debugobjects facilities to help catch misuse.  Currently, the
debugobjects interface is only available to builtin drivers and requires
a set of EXPORT_SYMBOL_GPL for use by modules.

I am using the debugobjects in i915.ko to try and catch some invalid
operations on embedded objects.  The problem currently only presents
itself across module unload so forcing i915 to be builtin is not an

The zram hot removal code calls idr_remove() even when zram_remove()
returns an error (typically -EBUSY).  This results in a leftover at the
device release, eventually leading to a crash when the module is
reloaded.

As described in the bug report below, the following procedure would
cause an Oops with zram:

 - provision three zram devices via modprobe zram num_devices=3
 - configure a size for each device
   + echo "1G" > /sys/block/$zram_name/disksize
 - mkfs and mount zram0 only
 - attempt to hot remove all three devices
   + echo 2 > /sys/class/zram-control/hot_remove
   + echo 1 > /sys/class/zram-control/hot_remove
   + echo 0 > /sys/class/zram-control/hot_remove
     - zram0 removal fails with EBUSY, as expected
 - unmount zram0
 - try zram0 hot remove again
   + echo 0 > /sys/class/zram-control/hot_remove
     - fails with ENODEV (unexpected)
 - unload zram kernel module
   + completes successfully
 - zram0 device node still exists
 - attempt to mount /dev/zram0
   + mount command is killed
   + following BUG is encountered

The following program triggers BUG() in munlock_vma_pages_range():

	// autogenerated by syzkaller (http://github.com/google/syzkaller)
	#include <sys/mman.h>

	int main()
	{
	  mmap((void*)0x20105000ul, 0xc00000ul, 0x2ul, 0x2172ul, -1, 0);

	  return 0;
	}

The test-case constructs the situation when munlock_vma_pages_range()
finds PTE-mapped THP-head in the middle of page table and, by mistake,
skips HPAGE_PMD_NR pages after that.

As result, on the next iteration it hits the middle of PMD-mapped THP
and gets upset seeing mlocked tail page.

The solution is only skip HPAGE_PMD_NR pages if the THP was mlocked
during munlock_vma_page().  It would guarantee that the page is
PMD-mapped as we never mlock PTE-mapeed THPs.

This enables CONFIG_MODVERSIONS again, but allows for missing symbol CRC

Some day I really do want to remove MODVERSIONS entirely.  Sadly, today
does not appear to be that day: Debian people apparently do want the
option to enable MODVERSIONS to make it easier to have external modules
across kernel versions, and this seems to be a fairly minimal fix for

  dbri: Fix compiler warning
  qlogicpti: Fix compiler warnings

dbri uses 'u32' for dma handle while invoking kernel DMA APIs,
instead of using dma_addr_t. This hasn't caused any 'incompatible
pointer type' warning on SPARC because until now dma_addr_t is of
type u32. However, recent changes in SPARC ATU (iommu) enabled 64bit
DMA and therefore dma_addr_t became of type u64. This makes
'incompatible pointer type' warnings inevitable.

e.g.
sound/sparc/dbri.c: In function ‘snd_dbri_create’:
sound/sparc/dbri.c:2538: warning: passing argument 3 of ‘dma_zalloc_coherent’ from incompatible pointer type
./include/linux/dma-mapping.h:608: note: expected ‘dma_addr_t *’ but argument is of type ‘u32 *’

For the record, dbri(sbus) driver never executes on sun4v. Therefore
even though 64bit DMA is enabled on SPARC, dbri continues to use
legacy iommu that guarantees DMA address is always in 32bit range.

This patch resolves above compiler warning.
