The naming of pgtable_page_{ctor,dtor}() seems to have confused a few
people, and until recently arm64 used these erroneously/pointlessly for
other levels of page table.
To make it incredibly clear that these only apply to the PTE level, and to
align with the naming of pgtable_pmd_page_{ctor,dtor}(), let's rename them
to pgtable_pte_page_{ctor,dtor}().
These changes were generated with the following shell script:
----
git grep -lw 'pgtable_page_.tor' | while read FILE; do
sed -i '{s/pgtable_page_ctor/pgtable_pte_page_ctor/}' $FILE;
sed -i '{s/pgtable_page_dtor/pgtable_pte_page_dtor/}' $FILE;
done
----
... with the documentation re-flowed to remain under 80 columns, and
whitespace fixed up in macros to keep backslashes aligned.
There should be no functional change as a result of this patch.

Cgroup v1 memcg controller has exposed a dedicated kmem limit to users
which turned out to be really a bad idea because there are paths which
cannot shrink the kernel memory usage enough to get below the limit (e.g.
because the accounted memory is not reclaimable). There are cases when
the failure is even not allowed (e.g. __GFP_NOFAIL). This means that the
kmem limit is in excess to the hard limit without any way to shrink and
thus completely useless. OOM killer cannot be invoked to handle the
situation because that would lead to a premature oom killing.
As a result many places might see ENOMEM returning from kmalloc and result
in unexpected errors. E.g. a global OOM killer when there is a lot of
free memory because ENOMEM is translated into VM_FAULT_OOM in #PF path and
therefore pagefault_out_of_memory would result in OOM killer.
Please note that the kernel memory is still accounted to the overall limit
along with the user memory so removing the kmem specific limit should
still allow to contain kernel memory consumption. Unlike the kmem one,
though, it invokes memory reclaim and targeted memcg oom killing if
necessary.
Start the deprecation process by crying to the kernel log. Let's see
whether there are relevant usecases and simply return to EINVAL in the
second stage if nobody complains in few releases.

The debug_pagealloc functionality is useful to catch buggy page allocator
users that cause e.g. use after free or double free. When page
inconsistency is detected, debugging is often simpler by knowing the call
stack of process that last allocated and freed the page. When page_owner
is also enabled, we record the allocation stack trace, but not freeing.
This patch therefore adds recording of freeing process stack trace to page
owner info, if both page_owner and debug_pagealloc are configured and
enabled. With only page_owner enabled, this info is not useful for the
memory leak debugging use case. dump_page() is adjusted to print the
info. An example result of calling __free_pages() twice may look like
this (note the page last free stack trace):

Currently, a value of '1" is written to /sys/kernel/slab/<slab>/shrink
file to shrink the slab by flushing out all the per-cpu slabs and free
slabs in partial lists. This can be useful to squeeze out a bit more
memory under extreme condition as well as making the active object counts
in /proc/slabinfo more accurate.
This usually applies only to the root caches, as the SLUB_MEMCG_SYSFS_ON
option is usually not enabled and "slub_memcg_sysfs=1" not set. Even if
memcg sysfs is turned on, it is too cumbersome and impractical to manage
all those per-memcg sysfs files in a real production system.
So there is no practical way to shrink memcg caches. Fix this by enabling
a proper write to the shrink sysfs file of the root cache to scan all the
available memcg caches and shrink them as well. For a non-root memcg
cache (when SLUB_MEMCG_SYSFS_ON or slub_memcg_sysfs is on), only that
cache will be shrunk when written.
On a 2-socket 64-core 256-thread arm64 system with 64k page after
a parallel kernel build, the the amount of memory occupied by slabs
before shrinking slabs were:
# grep task_struct /proc/slabinfo
task_struct 53137 53192 4288 61 4 : tunables 0 0
0 : slabdata 872 872 0
# grep "^S[lRU]" /proc/meminfo
Slab: 3936832 kB
SReclaimable: 399104 kB
SUnreclaim: 3537728 kB
After shrinking slabs (by echoing "1" to all shrink files):
# grep "^S[lRU]" /proc/meminfo
Slab: 1356288 kB
SReclaimable: 263296 kB
SUnreclaim: 1092992 kB
# grep task_struct /proc/slabinfo
task_struct 2764 6832 4288 61 4 : tunables 0 0

Hyper-V direct tlb flush function should be enabled for
guest that only uses Hyper-V hypercall. User space
hypervisor(e.g, Qemu) can disable KVM identification in
CPUID and just exposes Hyper-V identification to make
sure the precondition. Add new KVM capability KVM_CAP_
HYPERV_DIRECT_TLBFLUSH for user space to enable Hyper-V
direct tlb function and this function is default to be
disabled in KVM.

Summary of modules changes for the 5.4 merge window:
- Introduce exported symbol namespaces.
This new feature allows subsystem maintainers to partition and
categorize their exported symbols into explicit namespaces. Module
authors are now required to import the namespaces they need.
Some of the main motivations of this feature include: allowing kernel
developers to better manage the export surface, allow subsystem
maintainers to explicitly state that usage of some exported symbols
should only be limited to certain users (think: inter-module or
inter-driver symbols, debugging symbols, etc), as well as more easily
limiting the availability of namespaced symbols to other parts of the
kernel. With the module import requirement, it is also easier to spot
the misuse of exported symbols during patch review. Two new macros are
introduced: EXPORT_SYMBOL_NS() and EXPORT_SYMBOL_NS_GPL(). The API is
thoroughly documented in Documentation/kbuild/namespaces.rst.
- Some small code and kbuild cleanups here and there.

Merge tag 'modules-for-v5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/jeyu/linux
Pull modules updates from Jessica Yu:
"The main bulk of this pull request introduces a new exported symbol
namespaces feature. The number of exported symbols is increasingly
growing with each release (we're at about 31k exports as of 5.3-rc7)
and we currently have no way of visualizing how these symbols are
"clustered" or making sense of this huge export surface.
Namespacing exported symbols allows kernel developers to more
explicitly partition and categorize exported symbols, as well as more
easily limiting the availability of namespaced symbols to other parts
of the kernel. For starters, we have introduced the USB_STORAGE
namespace to demonstrate the API's usage. I have briefly summarized
the feature and its main motivations in the tag below.

- boot_mem_map is removed, providing a nice cleanup made possible by the
recent removal of bootmem.
- Some fixes to atomics, in general providing compiler barriers for
smp_mb__{before,after}_atomic plus fixes specific to Loongson CPUs or
MIPS32 systems using cmpxchg64().
- Conversion to the new generic VDSO infrastructure courtesy of Vincenzo
Frascino.
- Removal of undefined behavior in set_io_port_base(), fixing the
behavior of some MIPS kernel configurations when built with recent
clang versions.
- Initial MIPS32 huge page support, functional on at least Ingenic SoCs.
- pte_special() is now supported for some configurations, allowing among
other things generic fast GUP to be used.
- Miscellaneous fixes & cleanups.
And platform specific changes:
- Major improvements to Ingenic SoC support from Paul Cercueil, mostly
enabled by the inclusion of the new TCU (timer-counter unit) drivers
he's spent a very patient year or so working on. Plus some fixes for
X1000 SoCs from Zhou Yanjie.
- Netgear R6200 v1 systems are now supported by the bcm47xx platform.
- DT updates for BMIPS, Lantiq & Microsemi Ocelot systems.

about the state of the extent status cache.
Dropped workaround for pre-1970 dates which were encoded incorrectly
in pre-4.4 kernels. Since both the kernel correctly generates, and
e2fsck detects and fixes this issue for the past four years, it'e time
to drop the workaround. (Also, it's not like files with dates in the
distant past were all that common in the first place.)

This is more cleanup and consolidation of the hmm APIs and the very
strongly related mmu_notifier interfaces. Many places across the tree
using these interfaces are touched in the process. Beyond that a cleanup
to the page walker API and a few memremap related changes round out the
series:
- General improvement of hmm_range_fault() and related APIs, more
documentation, bug fixes from testing, API simplification &
consolidation, and unused API removal
- Simplify the hmm related kconfigs to HMM_MIRROR and DEVICE_PRIVATE, and
make them internal kconfig selects
- Hoist a lot of code related to mmu notifier attachment out of drivers by
using a refcount get/put attachment idiom and remove the convoluted
mmu_notifier_unregister_no_release() and related APIs.
- General API improvement for the migrate_vma API and revision of its only
user in nouveau
- Annotate mmu_notifiers with lockdep and sleeping region debugging
Two series unrelated to HMM or mmu_notifiers came along due to
dependencies:
- Allow pagemap's memremap_pages family of APIs to work without providing
a struct device
- Make walk_page_range() and related use a constant structure for function
pointers

This is some material that we picked up into our tree late or
that had complex inter-depondencies. The fact that there are these
interdependencies tends to meant that these are often actually the most
interesting new additions:
The new Aspeed AST2600 baseboard management controller is added, this
is a Cortex-A7 based follow-up to the ARM11 based AST2500 and had some
dependencies on other device drivers.
After many years, support for the MMP2 based OLPC XO-1.75 finally makes
it into the kernel.
The Armada 3720 based Turris Mox open source router platform is a late
addition and it follows some preparatory work across multiple branches.
The OMAP2+ platform had some large-scale cleanup involving driver
changes and DT changes, here we finish it off, dropping a lot of the
now-unused platform data.
The TI K3 platform that got added for 5.3 gains a lot more support
for individual bits on the SoC, this part just came late for the

clk registration by clk providers and debugfs "nice to haves" for rate
constraints. I'll highlight that we're now setting the clk_init_data pointer
inside struct clk_hw to NULL during clk_register(), which may break some
drivers that thought they could use that pointer during normal operations. That
change has been sitting in next for a while now but maybe something is still
broken. We'l see. Other than that the core framework changes aren't invasive
and they're fixing bugs, simplifying, and making things better.
On the clk driver side we got the usual addition of new SoC support, new
features for existing drivers, and bug fixes scattered throughout. The biggest
diffstat is the Amlogic driver that gained CPU clk support in addition to
migrating to the new way of specifying clk parents. After that the Qualcomm,
i.MX, Mediatek, and Rockchip clk drivers got support for various new SoCs and
clock controllers from those vendors.
Core:
- Drop NULL checks in clk debugfs
- Add min/max rates to clk debugfs
- Set clk_init_data pointer inside clk_hw to NULL after registration
- Make clk_bulk_get_all() return an 'id' corresponding to clock-names
- Evict parents from parent cache when they're unregistered
New Drivers:
- Add clock driver for i.MX8MN SoCs
- Support aspeed AST2600 SoCs
- Support for Mediatek MT6779 SoCs
- Support qcom SM8150 GCC and RPMh clks
- Support qcom QCS404 WCSS clks
- Add CPU clock support for Armada 7K/8K (specifically AP806 and AP807)
- Addition of clock driver for Rockchip rk3308 SoCs
Updates:

Merge tag 'powerpc-5.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc updates from Michael Ellerman:
"This is a bit late, partly due to me travelling, and partly due to a
power outage knocking out some of my test systems *while* I was
travelling.
- Initial support for running on a system with an Ultravisor, which
is software that runs below the hypervisor and protects guests
against some attacks by the hypervisor.
- Support for building the kernel to run as a "Secure Virtual
Machine", ie. as a guest capable of running on a system with an
Ultravisor.
- Some changes to our DMA code on bare metal, to allow devices with
medium sized DMA masks (> 32 && < 59 bits) to use more than 2GB of
DMA space.
- Support for firmware assisted crash dumps on bare metal (powernv).
- Two series fixing bugs in and refactoring our PCI EEH code.
- A large series refactoring our exception entry code to use gas
macros, both to make it more readable and also enable some future
optimisations.
As well as many cleanups and other minor features & fixups.

Pull drm updates from Dave Airlie:
"This is the main pull request for 5.4-rc1 merge window. I don't think
there is anything outstanding so next week should just be fixes, but
we'll see if I missed anything. I landed some fixes earlier in the
week but got delayed writing summary and sending it out, due to a mix
of sick kid and jetlag!
There are some fixes pending, but I'd rather get the main merge out of
the way instead of delaying it longer.
It's also pretty large in commit count and new amd header file size.
The largest thing is four new amdgpu products (navi12/14, arcturus and
renoir APU support).
Otherwise it's pretty much lots of work across the board, i915 has
started landing tigerlake support, lots of icelake fixes and lots of
locking reworking for future gpu support, lots of header file rework
(drmP.h is nearly gone), some old legacy hacks (DRM_WAIT_ON) have been
put into the places they are needed.

"This is the bulk of pin control changes for the v5.4 kernel cycle:
Core changes:
- Fix errors in example code in the documentation.
New drivers:
- Add support for JZ4760, JZ4760B, X1000, X1000E and X1500 to the
Ingenic driver.
- Support Cirrus Logic Madera CS47L92 and CS47L15.
- Support Allwinner Sunxi V3S.
- Support Aspeed 2600 BMC.
- Support Qualcomm SC7180.
- Support Marvell MVEBU CS115.
Driver improvements:
- Clean up a few drivers to use the devm_platform_ioremap_resource()
helper.
- Pass the irqchip when registering the gpio_chip in some pin
controllers that are also GPIO controllers.
- Support suspend/resume in the Tegra driver.
- Support pull-up on the Broadcom BCM2711.
- The Intel driver can now request locked pads.
- Fix the UFS reset pin in the Qualcomm SDM845 driver"
