The HMM mirror API can be use in two fashions. The first one where the
HMM user coalesce multiple page faults into one request and set flags per
pfns for of those faults. The second one where the HMM user want to
pre-fault a range with specific flags. For the latter one it is a waste
to have the user pre-fill the pfn arrays with a default flags value.
This patch adds a default flags value allowing user to set them for a
range without having to pre-fill the pfn array.

A common use case for HMM mirror is user trying to mirror a range and
before they could program the hardware it get invalidated by some core mm
event. Instead of having user re-try right away to mirror the range
provide a completion mechanism for them to wait for any active
invalidation affecting the range.
This also changes how hmm_range_snapshot() and hmm_range_fault() works by
not relying on vma so that we can drop the mmap_sem when waiting and
lookup the vma again on retry.

Minor optimization around hmm_pte_need_fault(). Rename for consistency
between code, comments and documentation. Also improves the comments on
all the possible returns values. Improve the function by returning the
number of populated entries in pfns array.

Patch series "mm: Generalize putback functions"]
putback_inactive_pages() and move_active_pages_to_lru() are almost
similar, so this patchset merges them ina single function.
This patch (of 4):
The patch moves the calculation from putback_inactive_pages() to
shrink_inactive_list(). This makes putback_inactive_pages() looking more
similar to move_active_pages_to_lru().
To do that, we account activated pages in reclaim_stat::nr_activate.
Since a page may change its LRU type from anon to file cache inside
shrink_page_list() (see ClearPageSwapBacked()), we have to account pages
for the both types. So, nr_activate becomes an array.
Previously we used nr_activate to account PGACTIVATE events, but now we
account them into pgactivate variable (since they are about number of
pages in general, not about sum of hpage_nr_pages).

Userfaultfd can be misued to make it easier to exploit existing
use-after-free (and similar) bugs that might otherwise only make a
short window or race condition available. By using userfaultfd to
stall a kernel thread, a malicious program can keep some state that it
wrote, stable for an extended period, which it can then access using an
existing exploit. While it doesn't cause the exploit itself, and while
it's not the only thing that can stall a kernel thread when accessing a
memory location, it's one of the few that never needs privilege.
We can add a flag, allowing userfaultfd to be restricted, so that in
general it won't be useable by arbitrary user programs, but in
environments that require userfaultfd it can be turned back on.
Add a global sysctl knob "vm.unprivileged_userfaultfd" to control
whether userfaultfd is allowed by unprivileged users. When this is
set to zero, only privileged users (root user, or users with the
CAP_SYS_PTRACE capability) will be able to use the userfaultfd
syscalls.
Andrea said:
: The only difference between the bpf sysctl and the userfaultfd sysctl
: this way is that the bpf sysctl adds the CAP_SYS_ADMIN capability
: requirement, while userfaultfd adds the CAP_SYS_PTRACE requirement,
: because the userfaultfd monitor is more likely to need CAP_SYS_PTRACE
: already if it's doing other kind of tracking on processes runtime, in
: addition of userfaultfd. In other words both syscalls works only for
: root, when the two sysctl are opt-in set to 1.

Pull gpio updates from Linus Walleij:
"This is the bulk of the GPIO changes for the v5.2 kernel cycle. A bit
later than usual because I was ironing out my own mistakes. I'm
holding some stuff back for the next kernel as a result, and this
should be a healthy and well tested batch.
Core changes:
- The gpiolib MMIO driver has been enhanced to handle two direction
registers, i.e. one register to set lines as input and one register
to set lines as output. It turns out some silicon engineer thinks
the ability to configure a line as input and output at the same
time makes sense, this can be debated but includes a lot of analog
electronics reasoning, and the registers are there and need to be
handled consistently. Unsurprisingly, we enforce the lines to be
either inputs or outputs in such schemes.
- Send in the proper argument value to .set_config() dispatched to
the pin control subsystem. Nobody used it before, now someone does,
so fix it to work as expected.
- The ACPI gpiolib portions can now handle pin bias setting (pull up
or pull down). This has been in the ACPI spec for years and we
finally have it properly integrated with Linux GPIOs. It was based
on an observation from Andy Schevchenko that Thomas Petazzoni's
changes to the core for biasing the PCA950x GPIO expander actually
happen to fit hand-in-glove with what the ACPI core needed. Such
nice synergies happen sometimes.
New drivers:
- A new driver for the Mellanox BlueField GPIO controller. This is
using 64bit MMIO registers and can configure lines as inputs and
outputs at the same time and after improving the MMIO library we
handle it just fine. Interesting.
- A new IXP4xx proper gpiochip driver with hierarchical interrupts
should be coming in from the ARM SoC tree as well.
Driver enhancements:
- The PCA053x driver handles the CAT9554 GPIO expander.
- The PCA053x driver handles the NXP PCAL6416 GPIO expander.
- Wake-up support on PCA053x GPIO lines.
- OMAP now does a nice asynchronous IRQ handling on wake-ups by
letting everything wake up on edges, and this makes runtime PM work
as expected too.
Misc:
- Several cleanups such as devres fixes.
- Get rid of some languager comstructs that cause problems when
compiling with LLVMs clang.
- Documentation review and update"

Pull powerpc updates from Michael Ellerman:
"Slightly delayed due to the issue with printk() calling
probe_kernel_read() interacting with our new user access prevention
stuff, but all fixed now.
The only out-of-area changes are the addition of a cpuhp_state, small
additions to Documentation and MAINTAINERS updates.
Highlights:
- Support for Kernel Userspace Access/Execution Prevention (like
SMAP/SMEP/PAN/PXN) on some 64-bit and 32-bit CPUs. This prevents
the kernel from accidentally accessing userspace outside
copy_to/from_user(), or ever executing userspace.
- KASAN support on 32-bit.
- Rework of where we map the kernel, vmalloc, etc. on 64-bit hash to
use the same address ranges we use with the Radix MMU.
- A rewrite into C of large parts of our idle handling code for
64-bit Book3S (ie. power8 & power9).
- A fast path entry for syscalls on 32-bit CPUs, for a 12-17% speedup
in the null_syscall benchmark.
- On 64-bit bare metal we have support for recovering from errors
with the time base (our clocksource), however if that fails
currently we hang in __delay() and never crash. We now have support
for detecting that case and short circuiting __delay() so we at
least panic() and reboot.
- Add support for optionally enabling the DAWR on Power9, which had
to be disabled by default due to a hardware erratum. This has the
effect of enabling hardware breakpoints for GDB, the downside is a
badly behaved program could crash the machine by pointing the DAWR
at cache inhibited memory. This is opt-in obviously.
- xmon, our crash handler, gets support for a read only mode where
operations that could change memory or otherwise disturb the system
are disabled.
Plus many clean-ups, reworks and minor fixes etc.

Pull clk framework updates from Stephen Boyd:
"We have a couple new features and changes in the core clk framework
this time around because we've finally gotten around to fixing some
long standing issues. There's still work to do though, so this pull
request is largely laying down the foundation for all the driver
changes to come in the next merge window.
The first problem we're alleviating is how parents of clks are
specified. With the new method, we should see lots of drivers migrate
away from the current design of string comparisons on the entire clk
tree to a more direct method where they can use clk_hw pointers or
more localized names specified in DT or via clkdev. This should reduce
our reliance on string comparisons for all the topology description
logic that we've been using for years and hopefully speed some things
up while avoiding problems we have with generating clk names.
Beyond that we also got rid of the CLK_IS_BASIC flag because it wasn't
really helping anyone and we introduced big-endian versions of the
basic clk types so that we can get rid of clk_{readl,writel}(). Both
of these are things that driver developers have tried to use over the
years that I typically bat away during code reviews because they're
not useful. It's great to see these two things go away so maintainers
can save time not worrying about these things.
On the driver side we got the usual collection of new SoC support and
non-critical fixes and updates to existing code. The big topics that
stand out are the new driver support for Mediatek MT8183 and MT8516
SoCs, Amlogic Meson8b and G12a SoCs, and the SiFive FU540 SoC. The
other patches in the driver pile are mostly fixes for things that are
being used for the first time or additions for clks that couldn't be
tested before because there wasn't a consumer driver that exercised
them. Details are below and also in the sub-maintainer tags.
Core:
- Remove clk_readl() and introduce BE versions of basic clk types
- Rewrite how clk parents can be specified to allow DT/clkdev lookups
- Removal of the CLK_IS_BASIC clk flag
- Framework documentation updates and fixes
New Drivers:
- Support for STM32F769

Pull RTC updates from Alexandre Belloni:
"A huge series from me this cycle. I went through many drivers to set
the date and time range supported by the RTC which helps solving HW
limitation when the time comes (as early as next year for some). This
time, I focused on drivers using .set_mms and .set_mmss64, allowing me
to remove those callbacks. About a third of the patches got reviews, I
actually own the RTCs and I tested another third and the remaining one
are unlikely to cause any issues.
Other than that, a single new driver and the usual fixes here and there.
Summary:
Subsystem:
- set_mmss and set_mmss64 rtc_ops removal
- Fix timestamp value for RTC_TIMESTAMP_BEGIN_1900
- Use SPDX identifier for the core
- validate upper bound of tm->tm_year

- Aspeed BMC SoC RTC
Drivers:
- abx80x: use rtc_add_group
- ds3232: nvram support
- pcf85063: add alarm, nvram, offset correction and microcrystal
rv8263 support
- x1205: add of_match_table

"The most significant changes at this cycle are the Sound Open Firmware
support from Intel for the common DSP framework along with its support
for Intel platforms. It's a door opened to a real "free" firmware (in

Pull drm updates from Dave Airlie:
"This has two exciting community drivers for ARM Mali accelerators.
Since ARM has never been open source friendly on the GPU side of the
house, the community has had to create open source drivers for the
Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx
series. Well done to all involved and hopefully this will help ARM
head in the right direction.
There is also now the ability if you don't have any of the legacy
drivers enabled (pre-KMS) to remove all the pre-KMS support code from
the core drm, this saves 10% or so in codesize on my machine.
i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo
moves out of staging.
