13d57e6435 regulator: axp20x: Use linear voltage ranges for AXP20X LDO4
AXP20X datasheet lists the possible voltage settings for LDO4, so
it was implemented using a voltage table. Upon closer examination,
the valid voltages can be mapped into 3 linear ranges.

Move AXP20X LDO4 to use linear ranges. The supporting code can be
reused with later AXP8xx PMICs, which have a number of regulators
that have 2 linear ranges.

94c39041ae regulator: axp20x: Remove voltage readout support for switch regulators
Switch-type regulators, such as DC1SW on AXP22X, are a secondary output
from DCDC1. They are just an on/off switch, and the driver should not
try to read its voltage directly from the DCDC1 control registers.

Instead, the core will pass down the voltage from the regulator supply
chain.

4a6180ea73 ASoC: rt5514: add rt5514 codec driver
This is the initial codec driver for rt5514. The codec includes a low power
DSP for voice wake up. The register address is incremental by 4 in the DSP
memory map. In order to recover the codec settings in the codec mode and
manipulate the DSP mode for voice wake up, we use the multi-level register
map. One is for ALSA API in codec mode that can be recovered by cache
before recording. Another is for DSP related settings that can be accessed
with 32bit address of the DSP in the application of voice wake up.

4643536474 mm: retire GUP WARN_ON_ONCE that outlived its usefulness
Trinity is now hitting the WARN_ON_ONCE we added in v3.15 commit
cda540ace6 ("mm: get_user_pages(write,force) refuse to COW in shared
areas").  The warning has served its purpose, nobody was harmed by that
change, so just remove the warning to generate less noise from Trinity.

Which reminds me of the comment I wrongly left behind with that commit
(but was spotted at the time by Kirill), which has since moved into a
separate function, and become even more obscure: delete it.

58c9d61f86 ipmi: put acpi.h with the other headers
Enclosing '#include <linux/acpi.h>' within '#ifdef CONFIG_ACPI' is
unnecessary, since it has its own conditional compile for CONFIG_ACPI.

Commit 0fbcf4af7c ("ipmi: Convert the IPMI SI ACPI handling to a
platform device") exposed this as a problem for platforms that do not
support ACPI when it introduced a call to ACPI_PTR() macro outside of
the CONFIG_ACPI conditional compile. This would have been perfectly
acceptable if acpi.h were not conditionally excluded for the non-acpi
platform, because the conditional compile within acpi.h defines
ACPI_PTR() to return NULL when compiled for non acpi platforms.

12c9d70bd5 mm: fix memory leak in copy_huge_pmd()
We allocate a pgtable but do not attach it to anything if the PMD is in
a DAX VMA, causing it to leak.

We certainly try to not free pgtables associated with the huge zero page
if the zero page is in a DAX VMA, so I think this is the right solution.
This needs to be properly audited.

c6400ba7e1 drivers/hwspinlock: fix race between radix tree insertion and lookup
of_hwspin_lock_get_id() is protected by the RCU lock, which means that
insertions can occur simultaneously with the lookup.  If the radix tree
transitions from a height of 0, we can see a slot with the indirect_ptr
bit set, which will cause us to at least read random memory, and could
cause other havoc.

Fix this by using the newly introduced radix_tree_iter_retry().

46437f9a55 radix-tree: fix race in gang lookup
If the indirect_ptr bit is set on a slot, that indicates we need to redo
the lookup.  Introduce a new function radix_tree_iter_retry() which
forces the loop to retry the lookup by setting 'slot' to NULL and
turning the iterator back to point at the problematic entry.

This is a pretty rare problem to hit at the moment; the lookup has to
race with a grow of the radix tree from a height of 0.  The consequences
of hitting this race are that gang lookup could return a pointer to a
radix_tree_node instead of a pointer to whatever the user had inserted
in the tree.

d977d56ce5 mm: warn about VmData over RLIMIT_DATA
This patch provides a way of working around a slight regression
introduced by commit 8463833590 ("mm: rework virtual memory
accounting").

Before that commit RLIMIT_DATA have control only over size of the brk
region.  But that change have caused problems with all existing versions
of valgrind, because it set RLIMIT_DATA to zero.

This patch fixes rlimit check (limit actually in bytes, not pages) and
by default turns it into warning which prints at first VmData misuse:

  "mmap: top (795): VmData 516096 exceed data ulimit 512000.  Will be forbidden soon."

Behavior is controlled by boot param ignore_rlimit_data=y/n and by sysfs
/sys/module/kernel/parameters/ignore_rlimit_data.  For now it set to "y".

461c7fa126 drivers/scsi/sg.c: mark VMA as VM_IO to prevent migration
Reduced testcase:

    #include <fcntl.h>
    #include <unistd.h>
    #include <sys/mman.h>
    #include <numaif.h>

    #define SIZE 0x2000

    int main()
    {
        int fd;
        void *p;

        fd = open("/dev/sg0", O_RDWR);
        p = mmap(NULL, SIZE, PROT_EXEC, MAP_PRIVATE | MAP_LOCKED, fd, 0);
        mbind(p, SIZE, 0, NULL, 0, MPOL_MF_MOVE);
        return 0;
    }

We shouldn't try to migrate pages in sg VMA as we don't have a way to
update Sg_scatter_hold::pages accordingly from mm core.

Let's mark the VMA as VM_IO to indicate to mm core that the VMA is not
migratable.

65376df582 proc: revert /proc/<pid>/maps [stack:TID] annotation
Commit b76437579d ("procfs: mark thread stack correctly in
proc/<pid>/maps") added [stack:TID] annotation to /proc/<pid>/maps.

Finding the task of a stack VMA requires walking the entire thread list,
turning this into quadratic behavior: a thousand threads means a
thousand stacks, so the rendering of /proc/<pid>/maps needs to look at a
million combinations.

The cost is not in proportion to the usefulness as described in the
patch.

Drop the [stack:TID] annotation to make /proc/<pid>/maps (and
/proc/<pid>/numa_maps) usable again for higher thread counts.

The [stack] annotation inside /proc/<pid>/task/<tid>/maps is retained, as
identifying the stack VMA there is an O(1) operation.

Siddesh said:
 "The end users needed a way to identify thread stacks programmatically and
  there wasn't a way to do that.  I'm afraid I no longer remember (or have
  access to the resources that would aid my memory since I changed
  employers) the details of their requirement.  However, I did do this on my
  own time because I thought it was an interesting project for me and nobody
  really gave any feedback then as to its utility, so as far as I am
  concerned you could roll back the main thread maps information since the
  information is available in the thread-specific files"

5c2ff95e41 numa: fix /proc/<pid>/numa_maps for hugetlbfs on s390
When working with hugetlbfs ptes (which are actually pmds) is not valid to
directly use pte functions like pte_present() because the hardware bit
layout of pmds and ptes can be different.  This is the case on s390.
Therefore we have to convert the hugetlbfs ptes first into a valid pte
encoding with huge_ptep_get().

Currently the /proc/<pid>/numa_maps code uses hugetlbfs ptes without
huge_ptep_get().  On s390 this leads to the following two problems:

1) The pte_present() function returns false (instead of true) for
   PROT_NONE hugetlb ptes. Therefore PROT_NONE vmas are missing
   completely in the "numa_maps" output.

2) The pte_dirty() function always returns false for all hugetlb ptes.
   Therefore these pages are reported as "mapped=xxx" instead of
   "dirty=xxx".

Therefore use huge_ptep_get() to correctly convert the hugetlb ptes.
