Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v5.5 kernel cycle
Core changes:
- Expose pull up/down flags for the GPIO character device to
userspace.
After clear input from the RaspberryPi and Beagle communities, it
has been established that prototyping, industrial automation and
make communities strongly need this feature, and as we want people
to use the character device, we have implemented the simple pull
up/down interface for GPIO lines.
This means we can specify that a (chip-specific) pull up/down
resistor can be enabled, but does not offer fine-grained control
such as cases where the resistance of the same pull resistor can be
controlled (yet).
- Introduce devm_fwnode_gpiod_get_index() and start to phase out the
old symbol devm_fwnode_get_index_gpiod_from_child().
- A bit of documentation clean-up work.
- Introduce a define for GPIO line directions and deploy it in all
GPIO drivers in the drivers/gpio directory.
- Add a special callback to populate pin ranges when cooperating with
the pin control subsystem and registering ranges as part of adding
a gpiolib driver and a gpio_irq_chip driver at the same time. This
is also deployed in the Intel Merrifield driver.
New drivers:
- RDA Micro GPIO controller.
- XGS-iproc GPIO driver.
Driver improvements:
- Wake event and debounce support on the Tegra 186 driver.
- Finalize the Aspeed SGPIO driver.
- MPC8xxx uses a normal IRQ handler rather than a chained handler"

Pull clk updates from Stephen Boyd:
"This merge window we have one small clk provider API in the core
framework and then a bunch of driver updates and a handful of new
drivers. In terms of diffstat the Qualcomm and Amlogic drivers are
high up there because of all the clk data introcued by new drivers.
The Nvidia Tegra driver had a lot of work done this cycle too to
support suspend/resume and memory controllers. And the OMAP clk driver
got proper clk and reset handling in place.
Rounding out the patches are various updates to remove unused data,
mark things static, correct incorrect data in drivers, etc. All the
little things that improve drivers and maintain code health. I will
point out that there's a patch in here for the GPIO clk driver, that
almost nobody uses, which changes behavior and causes clk_set_rate()
to try to change the GPIO gate clk's parent. Other than that things
are fairly well SoC specific here.
Core:
- Add a clk provider API to get current parent index
- Plug a memory leak in clk_unregister() path
New Drivers:
- CGU in Ingenix X1000
- Bitmain BM1880 clks
- Qualcomm MSM8998 GPU clk controllers
- Qualcomm SC7180 GCC and RPMH clk controllers
- Qualcomm QCS404 Q6SSTOP clk controllers
- Add support for the Renesas R-Car M3-W+ (r8a77961) SoC
- Add support for the Renesas RZ/G2N (r8a774b1) SoC
- Add Tegra20/30 External Memory Clock (EMC) support
Updates:
- Make gpio gate clks propagate rate setting up to parent
- Prepare Armada 3700 for suspend to RAM by moving PCIe
suspend/resume priority
- Drop unused variables, enums, etc. in various clk drivers
- Convert various drivers to use devm_platform_ioremap_resource()
- Use struct_size() some more in various clk drivers
- Improve Rockchip px30 clk tree
- Add suspend/resume support to Tegra210 clk driver
- Reimplement SOR clks on earlier Tegra SoCs, helping HDMI and DP
- Allwinner DT exports and H6 clk tree fixes
- Proper clk and reset handling for OMAP SoCs
- Revamped TI divider clk to clamp max divider
- Make 1443X/1416X PLL clock structure common for reusing among i.MX8
SoCs
- Drop IMX7ULP_CLK_MIPI_PLL clock, it shouldn't be used
- Add VIDEO2_PLL clock for imx8mq
- Add missing gate clock for pll1/2 fixed dividers on i.MX8 SoCs
- Add sm1 support in the Amlogic audio clock controller
- Switch some clocks on R-Car Gen2/3 to .determine_rate()
- Remove Renesas R-Car Gen2 legacy DT clock support
- Improve arithmetic divisions on Renesas R-Car Gen2 and Gen3

the unsafe usage is mostly gone from the kernel, having the types and

Pull sysctl system call removal from Eric Biederman:
"As far as I can tell we have reached the point where no one enables
the sysctl system call anymore. It still is enabled in a few
defconfigs but they are mostly the rarely used one and in asking
people about that it was more cut & paste enabled than anything else.
This is single commit that just deletes code. Leaving just enough code
so that the deprecated sysctl warning continues to be printed. If my
analysis turns out to be wrong and someone actually cares it will be
easy to revert this commit and have the system call again.
There was one new xtensa defconfig in linux-next that enabled the
system call this cycle and when asked about it the maintainer of the
code replied that it was not enabled on purpose. As of today's
linux-next tree that defconfig no longer enables the system call.
What we saw in the review discussion was that if we go a step farther
than my patch and mess with uapi headers there are pieces of code that
won't compile, but nothing minds the system call actually disappearing
from the kernel"

"Highlights:
- Infrastructure for secure boot on some bare metal Power9 machines.
The firmware support is still in development, so the code here
won't actually activate secure boot on any existing systems.
- A change to xmon (our crash handler / pseudo-debugger) to restrict
it to read-only mode when the kernel is lockdown'ed, otherwise it's
trivial to drop into xmon and modify kernel data, such as the
lockdown state.
- Support for KASLR on 32-bit BookE machines (Freescale / NXP).
- Fixes for our flush_icache_range() and __kernel_sync_dicache()
(VDSO) to work with memory ranges >4GB.
- Some reworks of the pseries CMM (Cooperative Memory Management)
driver to make it behave more like other balloon drivers and enable
some cleanups of generic mm code.
- A series of fixes to our hardware breakpoint support to properly
handle unaligned watchpoint addresses.
Plus a bunch of other smaller improvements, fixes and cleanups.

Pull pipe rework from David Howells:
"This is my set of preparatory patches for building a general
notification queue on top of pipes. It makes a number of significant
changes:
- It removes the nr_exclusive argument from __wake_up_sync_key() as
this is always 1. This prepares for the next step:
- Adds wake_up_interruptible_sync_poll_locked() so that poll can be
woken up from a function that's holding the poll waitqueue
spinlock.
- Change the pipe buffer ring to be managed in terms of unbounded
head and tail indices rather than bounded index and length. This
means that reading the pipe only needs to modify one index, not
two.
- A selection of helper functions are provided to query the state of
the pipe buffer, plus a couple to apply updates to the pipe
indices.
- The pipe ring is allowed to have kernel-reserved slots. This allows
many notification messages to be spliced in by the kernel without
allowing userspace to pin too many pages if it writes to the same
pipe.
- Advance the head and tail indices inside the pipe waitqueue lock
and use wake_up_interruptible_sync_poll_locked() to poke poll
without having to take the lock twice.
- Rearrange pipe_write() to preallocate the buffer it is going to
write into and then drop the spinlock. This allows kernel
notifications to then be added the ring whilst it is filling the
buffer it allocated. The read side is stalled because the pipe
mutex is still held.
- Don't wake up readers on a pipe if there was already data in it
when we added more.
- Don't wake up writers on a pipe if the ring wasn't full before we
removed a buffer"

powerpc/fixmap: fix crash with HIGHMEM
Commit
f2bb86937d86 ("powerpc/fixmap: don't clear fixmap area in
paging_init()") removed the clearing of fixmap area in order to
avoid clearing fixmapped areas set earlier.
However unlike all other users of fixmap which use __set_fixmap(),
HIGHMEM functions directly use __set_pte_at(). This means
the page table must pre-exist, otherwise the following crash
can be encoutered due to the lack of entry in the PGD.

Merge branch 'vmwgfx-coherent' of git://people.freedesktop.org/~thomash/linux into drm-next
Graphics APIs like OpenGL 4.4 and Vulkan require the graphics driver
to provide coherent graphics memory, meaning that the GPU sees any
content written to the coherent memory on the next GPU operation that
touches that memory, and the CPU sees any content written by the GPU
to that memory immediately after any fence object trailing the GPU
operation is signaled.
Paravirtual drivers that otherwise require explicit synchronization
needs to do this by hooking up dirty tracking to pagefault handlers
and buffer object validation.
Provide mm helpers needed for this and that also allow for huge pmd-
and pud entries (patch 1-3), and the associated vmwgfx code (patch 4-7).
The code has been tested and exercised by a tailored version of mesa
where we disable all explicit synchronization and assume graphics memory
is coherent. The performance loss varies of course; a typical number is
around 5%.

Pull tracing updates from Steven Rostedt:
"New tracing features:
- New PERMANENT flag to ftrace_ops when attaching a callback to a
function.
As /proc/sys/kernel/ftrace_enabled when set to zero will disable
all attached callbacks in ftrace, this has a detrimental impact on
live kernel tracing, as it disables all that it patched. If a
ftrace_ops is registered to ftrace with the PERMANENT flag set, it
will prevent ftrace_enabled from being disabled, and if
ftrace_enabled is already disabled, it will prevent a ftrace_ops
with PREMANENT flag set from being registered.
- New register_ftrace_direct().
As eBPF would like to register its own trampolines to be called by
the ftrace nop locations directly, without going through the ftrace
trampoline, this function has been added. This allows for eBPF
trampolines to live along side of ftrace, perf, kprobe and live
patching. It also utilizes the ftrace enabled_functions file that
keeps track of functions that have been modified in the kernel, to
allow for security auditing.
- Allow for kernel internal use of ftrace instances.
Subsystems in the kernel can now create and destroy their own
tracing instances which allows them to have their own tracing
buffer, and be able to record events without worrying about other
users from writing over their data.
- New seq_buf_hex_dump() that lets users use the hex_dump() in their
seq_buf usage.
- Notifications now added to tracing_max_latency to allow user space
to know when a new max latency is hit by one of the latency
tracers.
- Wider spread use of generic compare operations for use of bsearch
and friends.
- More synthetic event fields may be defined (32 up from 16)
- Use of xarray for architectures with sparse system calls, for the
system call trace events.
This along with small clean ups and fixes"

That allows a process to poison the RSB (called Link Stack on Power

If the victim process can be induced to execute a leak gadget then it
may be possible to extract information from the victim via a side
channel.
The fix is to correctly activate the link stack flush mitigation on
all CPUs that have any mitigation of Spectre v2 in userspace enabled.
There's a second commit which adds a link stack flush in the KVM guest

net: wireless: intel: iwlwifi: fix GRO_NORMAL packet stalling
Commit
6570bc79c0df ("net: core: use listified Rx for GRO_NORMAL in
napi_gro_receive()") has applied batched GRO_NORMAL packets processing
to all napi_gro_receive() users, including mac80211-based drivers.
However, this change has led to a regression in iwlwifi driver [1][2] as
it is required for NAPI users to call napi_complete_done() or
napi_complete() and the end of every polling iteration, whilst iwlwifi
doesn't use NAPI scheduling at all and just calls napi_gro_flush().
In that particular case, packets which have not been already flushed
from napi->rx_list stall in it until at least next Rx cycle.
Fix this by adding a manual flushing of the list to iwlwifi driver right
before napi_gro_flush() call to mimic napi_complete() logics.
I prefer to open-code gro_normal_list() rather than exporting it for 2
reasons:
* to prevent from using it and napi_gro_flush() in any new drivers,
as it is the *really* bad way to use NAPI that should be avoided;
* to keep gro_normal_list() static and don't lose any CC optimizations.
I also don't add the "Fixes:" tag as the mentioned commit was only a
trigger that only exposed an improper usage of NAPI in this particular
driver.

"Here is the "big" set of driver core patches for 5.5-rc1
There's a few minor cleanups and fixes in here, but the majority of

- debugfs api cleanups and fixes
- driver core device link support for boot dependancy issues
The debugfs api cleanups are working to slowly refactor the debugfs
apis so that it is even harder to use incorrectly. That work has been
happening for the past few kernel releases and will continue over
time, it's a long-term project/goal
The driver core device link support missed 5.4 by just a bit, so it's
been sitting and baking for many months now. It's from Saravana Kannan
to help resolve the problems that DT-based systems have at boot time
with dependancy graphs and kernel modules. Turns out that no one has
actually tried to build a generic arm64 kernel with loads of modules
and have it "just work" for a variety of platforms (like a distro
kernel). The big problem turned out to be a lack of dependency
information between different areas of DT entries, and the work here
resolves that problem and now allows devices to boot properly, and
quicker than a monolith kernel.

names: these may changed at runtime under certain circumstances to
kstrdup them.
GPIO related:
- Work is ongoing to move to passing the irqchip along as a templated
struct gpio_irq_chip when adding a standard gpiolib-based irqchip
to a GPIO controller, a few patches in this cycle switches a few
pin control drivers over to using this method.
New hardware support:
- Intel Lightning Mountain SoC pin controller and GPIO support, a
first Intel platform to use device tree rather than ACPI to
configure the system. News reports says that this SoC is a network
processor.
- Qualcomm MSM8976 and MSM8956
- Qualcomm PMIC GPIO now also supports PM6150 and PM6150L
- Qualcomm SPMI MPP and SPMI GPIO for PM8950 and PMI8950
- Rockchip RK3308
- Renesas R8A77961
- Allwinner Meson-A1
Driver improvements:
- get_multiple and set_multiple support for the AT91-PIO4 driver.
- Convert Qualcomm SSBI GPIO to use the hierarchical IRQ helpers in
the GPIOlib irqchip"

powerpc: Define arch_is_kernel_initmem_freed() for lockdep
Under certain circumstances, we hit a warning in lockdep_register_key:
if (WARN_ON_ONCE(static_obj(key)))
return;
This occurs when the key falls into initmem that has since been freed
and can now be reused. This has been observed on boot, and under
memory pressure.
Define arch_is_kernel_initmem_freed(), which allows lockdep to
correctly identify this memory as dynamic.
This fixes a bug picked up by the powerpc64 syzkaller instance where
