When hotplugging memory, it is possible that two calls are being made to
register_mem_sect_under_node().
One comes from __add_section()->hotplug_memory_register() and the other
from add_memory_resource()->link_mem_sections() if we had to register a
new node.
In case we had to register a new node, hotplug_memory_register() will
only handle/allocate the memory_block's since
register_mem_sect_under_node() will return right away because the node
it is not online yet.
I think it is better if we leave hotplug_memory_register() to
handle/allocate only memory_block's and make link_mem_sections() to call
register_mem_sect_under_node().
So this patch removes the call to register_mem_sect_under_node() from
hotplug_memory_register(), and moves the call to link_mem_sections() out
of the condition, so it will always be called. In this way we only have
one place where the memory sections are registered.

Use new return type vm_fault_t for fault handler. For now, this is just
documenting that the function returns a VM_FAULT value rather than an
errno. Once all instances are converted, vm_fault_t will become a
distinct type.
Ref-> commit 1c8f422059ae ("mm: change return type to vm_fault_t")
In this patch all the caller of handle_mm_fault() are changed to return
vm_fault_t type.

32-bit CLOCK_REALTIME timestamps overflow in year 2038, so all such
interfaces are deprecated now. For the FW_CDEV_IOC_GET_CYCLE_TIMER2
ioctl, we already support 64-bit timestamps, but the implementation
still uses timespec.
This changes the code to use timespec64 instead with the appropriate
accessor functions.

This patch is reworked from an earlier patch that Dan has posted:
https://patchwork.kernel.org/patch/10131727/
VM_MIXEDMAP is used by dax to direct mm paths like vm_normal_page() that
the memory page it is dealing with is not typical memory from the linear
map. The get_user_pages_fast() path, since it does not resolve the vma,
is already using {pte,pmd}_devmap() as a stand-in for VM_MIXEDMAP, so we
use that as a VM_MIXEDMAP replacement in some locations. In the cases
where there is no pte to consult we fallback to using vma_is_dax() to
detect the VM_MIXEDMAP special case.
Now that we have explicit driver pfn_t-flag opt-in/opt-out for
get_user_pages() support for DAX we can stop setting VM_MIXEDMAP. This
also means we no longer need to worry about safely manipulating vm_flags
in a future where we support dynamically changing the dax mode of a
file.
DAX should also now be supported with madvise_behavior(), vma_merge(),
and copy_page_range().
This patch has been tested against ndctl unit test. It has also been
tested against xfstests commit: 625515d using fake pmem created by
memmap and no additional issues have been observed.

Pull rdma updates from Jason Gunthorpe:
"This has been a large cycle for RDMA, with several major patch series
reworking parts of the core code.
- Rework the so-called 'gid cache' and internal APIs to use a kref'd
pointer to a struct instead of copying, push this upwards into the
callers and add more stuff to the struct. The new design avoids
some ugly races the old one suffered with. This is part of the
namespace enablement work as the new struct is learning to be
namespace aware.
- Various uapi cleanups, moving more stuff to include/uapi and fixing
some long standing bugs that have recently been discovered.
- Driver updates for mlx5, mlx4 i40iw, rxe, cxgb4, hfi1, usnic,
pvrdma, and hns
- Provide max_send_sge and max_recv_sge attributes to better support
HW where these values are asymmetric.
- mlx5 user API 'devx' allows sending commands directly to the device
FW, instead of trying to cram every wild and niche feature into the
common API. Sort of like what GPU does.
- Major write() and ioctl() API rework to cleanly support PCI device
hot unplug and advance the ioctl conversion work
- Sparse and compile warning cleanups
- Add 'const' to the ib_poll_cq() signature, and permit a NULL
'bad_wr', which is the common use case
- Various patches to avoid high order allocations across the stack
- SRQ support for cxgb4, hns and qedr
- Changes to IPoIB to better follow the netdev model for working with
struct net_device liftime"

Pull powerpc updates from Michael Ellerman:
"Notable changes:
- A fix for a bug in our page table fragment allocator, where a page
table page could be freed and reallocated for something else while
still in use, leading to memory corruption etc. The fix reuses
pt_mm in struct page (x86 only) for a powerpc only refcount.
- Fixes to our pkey support. Several are user-visible changes, but
bring us in to line with x86 behaviour and/or fix outright bugs.
Thanks to Florian Weimer for reporting many of these.
- A series to improve the hvc driver & related OPAL console code,
which have been seen to cause hardlockups at times. The hvc driver
changes in particular have been in linux-next for ~month.
- Increase our MAX_PHYSMEM_BITS to 128TB when SPARSEMEM_VMEMMAP=y.
- Remove Power8 DD1 and Power9 DD1 support, neither chip should be in
use anywhere other than as a paper weight.
- An optimised memcmp implementation using Power7-or-later VMX
instructions
- Support for barrier_nospec on some NXP CPUs.
- Support for flushing the count cache on context switch on some IBM
CPUs (controlled by firmware), as a Spectre v2 mitigation.
- A series to enhance the information we print on unhandled signals
to bring it into line with other arches, including showing the
offending VMA and dumping the instructions around the fault.

git://people.freedesktop.org/~robclark/linux into drm-next
An optional follow-on PR for 4.19, on top of previous -fixes PR, which
brings in a6xx support.
These patches have been on list since earlier in the year (mostly
waiting for userspace). They have been in linux-next since earlier in
the week, now that we have freedreno userspace working on a6xx[1][2].
So far glmark2, Chromium/ChromiumOS, gnome-shell, glamor, xonotic,
etc, are working. And a healthy chuck of deqp works, and I've been
busy fixing things. The needed libdrm changes (no new uapi changes
needed) are already on master, and the 2nd branch is rebased on that.

We need to free up them after veth_close() so that any packets will not

Also move queues allocation to veth_dev_init() to be in line with stats

Prepare input updates for 4.19 merge window.

The allocated size can be (at least?) as large as megabytes, and
there's no need for it to be physically contiguous.
May avoid spurious failures to initialize / suspend the corresponding
block while there's memory pressure.

We don't have to define an extra config symbol, IS_REACHABLE does
what we need. And having this config symbol just to save the few
bytes of hwmon support on non-DS3231 chips isn't worth it IMO

Pull clk updates from Stephen Boyd:
"The new and exciting feature this time around is in the clk core.
We've added duty cycle support to the clk API so that clk signal duty
cycle ratios can be adjusted while taking into account things like clk
dividers and clk tree hierarchy. So far only one SoC has implemented
support for this, but I expect there will be more to come in the
future.
Outside of the core, we have the usual pile of clk driver updates and
additions. The Amlogic meson driver got the most lines in the diffstat
this time around because it added support for a whole bunch of
hardware and duty cycle configuration. After that the Rockchip PX30,
Qualcomm SDM845, and Renesas SoC drivers fill in a majority of the
diff. We're left with the collection of non-critical fixes after that.
Overall it looks pretty quiet this time.
Core:
- Clk duty cycle support
- Proper CLK_SET_RATE_GATE support throughout the tree
New Drivers:
- Actions Semi Owl series S700 SoC clk driver
- Qualcomm SDM845 display clock controller
- i.MX6SX ocram_s clk support

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.19 kernel cycle.
I don't know if anything in particular stands out. Maybe the Aspeed
coprocessor thing from Benji: Aspeed is doing baseboard management
chips (BMC's) for servers etc.
These Aspeed's are ARM processors that exist inside (I guess) Intel
servers, and they are moving forward to using mainline Linux in those.
This is one of the pieces of the puzzle to achive that. They are doing
OpenBMC, it's pretty cool: https://lwn.net/Articles/683320/
Summary:
Core changes:
- Add a new API for explicitly naming GPIO consumers, when needed.
- Don't let userspace set values on input lines. While we do not
think anyone would do this crazy thing we better plug the hole
before someone uses it and think it's a nifty feature.
- Avoid calling chip->request() for unused GPIOs.
New drivers/subdrivers:
- The Mediatek MT7621 is supported which is a big win for OpenWRT and
similar router distributions using this chip, as it seems every
major router manufacturer on the planet has made products using
this chip: https://wikidevi.com/wiki/MediaTek_MT7621
- The Tegra 194 is now supported.
- The IT87 driver now supports IT8786E and IT8718F super-IO chips.
- Add support for Rockchip RK3328 in the syscon GPIO driver.
Driver changes:
- Handle the get/set_multiple() properly on MMIO chips with inverted
direction registers. We didn't have this problem until a new chip
appear that has get/set registers AND inverted direction bits, OK
now we handle it.
- A patch series making more error codes percolate upward properly
for different errors on gpiochip_lock_as_irq().
- Get/set multiple for the OMAP driver, accelerating these multiple
line operations if possible.
- A coprocessor interface for the Aspeed driver. Sometimes a few GPIO
lines need to be grabbed by a co-processor for doing automated
tasks, sometimes they are available as GPIO lines. By adding an
explicit API in this driver we make it possible for the two line
consumers to coexist. (This work was made available on the
ib-aspeed branch, which may be appearing in other pull requests.)
- Implemented .get_direction() and open drain in the SCH311x driver.
- Continuing cleanup of included headers in GPIO drivers"
