libnvdimm for 4.6
1/ Asynchronous address range scrub:
Given the capacities of next generation persistent memory devices a
scrub operation to find all poison may take 10s of seconds. We want
this scrub work to be done asynchronously with the rest of system
initialization, so we move it out of line from the NFIT probing, i.e.
acpi_nfit_add().
2/ Clear poison:
ACPI 6.1 introduces the ability to send "clear error" commands to the
ACPI0012:00 device representing the root of an "nvdimm bus". Similar to
relocating a bad block on a disk, this support clears media errors in
response to a write.
3/ Persistent memory resource tracking:
A persistent memory range may be designated as simply "reserved" by
platform firmware in the efi/e820 memory map. Later when the NFIT
driver loads it discovers that the range is "Persistent Memory". The
NFIT bus driver inserts a resource to advertise that "persistent"
attribute in the system resource tree for /proc/iomem and
kernel-internal usages.
4/ Miscellaneous cleanups and fixes:
Workaround section misaligned pmem ranges when allocating a struct page
memmap, fix handling of the read-only case in the ioctl path, and clean
up block device major number allocation.

- Most attention this cycle went to optimizing blk-mq request-based DM
(dm-mq) that is used exclussively by DM multipath.
- A stable fix for dm-mq that eliminates excessive context switching
offers the biggest performance improvement (for both IOPs and
throughput).
- But more work is needed, during the next cycle, to reduce spinlock
contention in DM multipath on large NUMA systems.
- A stable fix for a NULL pointer seen when DM stats is enabled on a DM
multipath device that must requeue an IO due to path failure.
- A stable fix for DM snapshot to disallow the COW and origin devices
from being identical. This amounts to graceful failure in the face of
userspace error because these devices shouldn't ever be identical.
- Stable fixes for DM cache and DM thin provisioning to address crashes
seen if/when their respective metadata device experiences failures
that cause the transition to 'fail_io' mode.
- The DM cache 'mq' policy is now an alias for the 'smq' policy. The
'smq' policy proved to be consistently better than 'mq'. As such
'mq', with all its complex user-facing tunables, has been eliminated.
- Improve DM thin provisioning to consistently return -ENOSPC once the
thin-pool's data volume is out of space.
- Improve DM core to properly handle error propagation if
bio_integrity_clone() fails in clone_bio().
- Other small cleanups and improvements to DM core.

Pull power management and ACPI updates from Rafael Wysocki:
"This time the majority of changes go into cpufreq and they are
significant.
First off, the way CPU frequency updates are triggered is different
now. Instead of having to set up and manage a deferrable timer for
each CPU in the system to evaluate and possibly change its frequency
periodically, cpufreq governors set up callbacks to be invoked by the
scheduler on a regular basis (basically on utilization updates). The
"old" governors, "ondemand" and "conservative", still do all of their
work in process context (although that is triggered by the scheduler
now), but intel_pstate does it all in the callback invoked by the
scheduler with no need for any additional asynchronous processing.
Of course, this eliminates the overhead related to the management of
all those timers, but also it allows the cpufreq governor code to be
simplified quite a bit. On top of that, the common code and data
structures used by the "ondemand" and "conservative" governors are
cleaned up and made more straightforward and some long-standing and
quite annoying problems are addressed. In particular, the handling of
governor sysfs attributes is modified and the related locking becomes
more fine grained which allows some concurrency problems to be avoided
(particularly deadlocks with the core cpufreq code).
In principle, the new mechanism for triggering frequency updates
allows utilization information to be passed from the scheduler to
cpufreq. Although the current code doesn't make use of it, in the
works is a new cpufreq governor that will make decisions based on the
scheduler's utilization data. That should allow the scheduler and
cpufreq to work more closely together in the long run.
In addition to the core and governor changes, cpufreq drivers are
updated too. Fixes and optimizations go into intel_pstate, the
cpufreq-dt driver is updated on top of some modification in the
Operating Performance Points (OPP) framework and there are fixes and
other updates in the powernv cpufreq driver.
Apart from the cpufreq updates there is some new ACPICA material,
including a fix for a problem introduced by previous ACPICA updates,
and some less significant changes in the ACPI code, like CPPC code
optimizations, ACPI processor driver cleanups and support for loading
ACPI tables from initrd.
Also updated are the generic power domains framework, the Intel RAPL
power capping driver and the turbostat utility and we have a bunch of
traditional assorted fixes and cleanups.
Specifics:
- Redesign of cpufreq governors and the intel_pstate driver to make
them use callbacks invoked by the scheduler to trigger CPU
frequency evaluation instead of using per-CPU deferrable timers for
that purpose (Rafael Wysocki).

One of the largest releases for KVM... Hardly any generic improvement,
but lots of architecture-specific changes.
* ARM:
- VHE support so that we can run the kernel at EL2 on ARMv8.1 systems
- PMU support for guests
- 32bit world switch rewritten in C
- various optimizations to the vgic save/restore code.
* PPC:
- enabled KVM-VFIO integration ("VFIO device")
- optimizations to speed up IPIs between vcpus
- in-kernel handling of IOMMU hypercalls
- support for dynamic DMA windows (DDW).
* s390:
- provide the floating point registers via sync regs;
- separated instruction vs. data accesses
- dirty log improvements for huge guests
- bugfixes and documentation improvements.
* x86:
- Hyper-V VMBus hypercall userspace exit
- alternative implementation of lowest-priority interrupts using vector
hashing (for better VT-d posted interrupt support)
- fixed guest debugging with nested virtualizations
- improved interrupt tracking in the in-kernel IOAPIC
- generic infrastructure for tracking writes to guest memory---currently
its only use is to speedup the legacy shadow paging (pre-EPT) case, but
in the future it will be used for virtual GPUs as well
- much cleanup (LAPIC, kvmclock, MMU, PIT), including ubsan fixes.

the mess we got ourselves into with the endianness handling but also in
other areas too:
- Fixes for the endianness handling so that we now explicltly default
to little endian (the code used to do this by accident). This
fixes handling of explictly specified endianness on big endian
systems.
- Optimisation of the implementation of register striding.
- A refectoring of the _update_bits() code to reduce duplication.
- Fixes and enhancements for the interrupt implementation which
make it easier to use in a wider range of systems.

spi: Updates for v4.6
Not the biggest set of changes for SPI but a bit of a pickup in activity
on the core:
- Support for memory mapped read from flash devices via a SPI
controller.
- The beginnings of a message rewriting framework in the core which
should in time allow us to support transforming messages to work
around the limits of controllers or optimise the performance for
controllers transparently to calling drivers.
- Updates to the PXA2xx, the main functional change being to improve
the ACPI support.
- A new driver for the Analog Devices AXI SPI engine.

autofs: show pipe inode in mount options
This is required for CRIU (Checkpoint Restart In Userspace) to migrate a mount point when write end in user space is closed. Below is a brief description of the problem. To migrate a non-catatonic autofs mount point, one has to restore the control pipe between kernel and autofs master process. One of the autofs masters is systemd, which closes pipe write end after passing it to the kernel with mount call. To be able to restore the systemd control pipe one has to know which read pipe end in systemd corresponds to the write pipe end in the kernel. The pipe "fd" in mount options is not enough because it was closed and probably replaced by some other descriptor. Thus, some other attribute is required to be able to find the read pipe end. The best attribute to use to find the correct pipe end is inode number becuase it's unique for the whole system and can't be reused while the autofs mount exists. This attribute can also be used to recognize a situation where an autofs mount has no master (no process with specified "pgrp" or no file descriptor with "pipe_ino", specified in autofs mount options).

kallsyms: add support for relative offsets in kallsyms address table
Similar to how relative extables are implemented, it is possible to emit the kallsyms table in such a way that it contains offsets relative to some anchor point in the kernel image rather than absolute addresses. On 64-bit architectures, it cuts the size of the kallsyms address table in half, since offsets between kernel symbols can typically be expressed in 32 bits. This saves several hundreds of kilobytes of permanent .rodata on average. In addition, the kallsyms address table is no longer subject to dynamic relocation when CONFIG_RELOCATABLE is in effect, so the relocation work done after decompression now doesn't have to do relocation updates for all these values. This saves up to 24 bytes (i.e., the size of a ELF64 RELA relocation table entry) per value, which easily adds up to a couple of megabytes of uncompressed __init data on ppc64 or arm64. Even if these relocation entries typically compress well, the combined size reduction of 2.8 MB uncompressed for a ppc64_defconfig build (of which 2.4 MB is __init data) results in a ~500 KB space saving in the compressed image. Since it is useful for some architectures (like x86) to retain the ability to emit absolute values as well, this patch also adds support for capturing both absolute and relative values when KALLSYMS_ABSOLUTE_PERCPU is in effect, by emitting absolute per-cpu addresses as positive 32-bit values, and addresses relative to the lowest encountered relative symbol as negative values, which are subtracted from the runtime address of this base symbol to produce the actual address. Support for the above is enabled by default for all architectures except IA-64 and Tile-GX, whose symbols are too far apart to capture in this manner.

scripts/kallsyms.c has a special --absolute-percpu command line option which deals with the zero based per cpu offsets that are used when building for SMP on x86_64.

mm: memcontrol: drop unnecessary lru locking from mem_cgroup_migrate()
Migration accounting in the memory controller used to have to handle both oldpage and newpage being on the LRU already; fuse's page cache replacement used to pass a recycled newpage that had been uncharged but not freed and removed from the LRU, and the memcg migration code used to uncharge oldpage to "pass on" the existing charge to newpage. Nowadays, pages are no longer uncharged when truncated from the page cache, but rather only at free time, so if a LRU page is recycled in page cache replacement it'll also still be charged. And we bail out of the charge transfer altogether in that case. Tell commit_charge() that we know newpage is not on the LRU, to avoid taking the zone->lru_lock unnecessarily from the migration path. But also, oldpage is no longer uncharged inside migration. We only use oldpage for its page->mem_cgroup and page size, so we don't care about its LRU state anymore either.

mm/compaction: speed up pageblock_pfn_to_page() when zone is contiguous
There is a performance drop report due to hugepage allocation and in there half of cpu time are spent on pageblock_pfn_to_page() in compaction [1]. In that workload, compaction is triggered to make hugepage but most of pageblocks are un-available for compaction due to pageblock type and skip bit so compaction usually fails. Most costly operations in this case is to find valid pageblock while scanning whole zone range. To check if pageblock is valid to compact, valid pfn within pageblock is required and we can obtain it by calling pageblock_pfn_to_page(). This function checks whether pageblock is in a single zone and return valid pfn if possible. Problem is that we need to check it every time before scanning pageblock even if we re-visit it and this turns out to be very expensive in this workload. Although we have no way to skip this pageblock check in the system where hole exists at arbitrary position, we can use cached value for zone continuity and just do pfn_to_page() in the system where hole doesn't exist. This optimization considerably speeds up in above workload. Before vs After Max: 1096 MB/s vs 1325 MB/s Min: 635 MB/s 1015 MB/s Avg: 899 MB/s 1194 MB/s Avg is improved by roughly 30% [2].

If there is a hole in the pageblock, passing arbitrary position to pageblock_pfn_to_page() could cause to skip whole pageblock scanning, instead of just skipping the hole page. For deterministic behaviour, it's better to always pass pageblock aligned range to pageblock_pfn_to_page(). It will also help further optimization on pageblock_pfn_to_page() in the following patch.

mm/compaction: fix invalid free_pfn and compact_cached_free_pfn
free_pfn and compact_cached_free_pfn are the pointer that remember restart position of freepage scanner. When they are reset or invalid, we set them to zone_end_pfn because freepage scanner works in reverse direction. But, because zone range is defined as [zone_start_pfn, zone_end_pfn), zone_end_pfn is invalid to access. Therefore, we should not store it to free_pfn and compact_cached_free_pfn. Instead, we need to store zone_end_pfn - 1 to them. There is one more thing we should consider. Freepage scanner scan reversely by pageblock unit. If free_pfn and compact_cached_free_pfn are set to middle of pageblock, it regards that sitiation as that it already scans front part of pageblock so we lose opportunity to scan there. To fix-up, this patch do round_down() to guarantee that reset position will be pageblock aligned. Note that thanks to the current pageblock_pfn_to_page() implementation, actual access to zone_end_pfn doesn't happen until now. But, following patch will change pageblock_pfn_to_page() so this patch is needed from now on.

mm/memblock.c: remove unnecessary memblock_type variable
We define struct memblock_type *type in the memblock_add_region() and memblock_reserve_region() functions only for passing it to the memlock_add_range() and memblock_reserve_range() functions. Let's remove these variables and will pass a type directly.

x86: query dynamic DEBUG_PAGEALLOC setting
We can use debug_pagealloc_enabled() to check if we can map the identity mapping with 2MB pages. We can also add the state into the dump_stack output. The patch does not touch the code for the 1GB pages, which ignored CONFIG_DEBUG_PAGEALLOC. Do we need to fence this as well?

thp: cleanup split_huge_page()
After one of bugfixes to freeze_page(), we don't have freezed pages in rmap, therefore mapcount of all subpages of freezed THP is zero. And we have assert for that.
