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()

This is a series of cleanups for the y2038 work, mostly intended
for namespace cleaning: the kernel defines the traditional
time_t, timeval and timespec types that often lead to y2038-unsafe
code. Even though the unsafe usage is mostly gone from the kernel,
having the types and associated functions around means that we
can still grow new users, and that we may be missing conversions
to safe types that actually matter.
There are still a number of driver specific patches needed to
get the last users of these types removed, those have been
submitted to the respective maintainers.

Pull y2038 cleanups from Arnd Bergmann:
"y2038 syscall implementation cleanups
This is a series of cleanups for the y2038 work, mostly intended for
namespace cleaning: the kernel defines the traditional time_t, timeval
and timespec types that often lead to y2038-unsafe code. Even though
the unsafe usage is mostly gone from the kernel, having the types and
associated functions around means that we can still grow new users,
and that we may be missing conversions to safe types that actually
matter.
There are still a number of driver specific patches needed to get the
last users of these types removed, those have been submitted to the
respective maintainers"

y2038: alarm: fix half-second cut-off
y2038: ipc: fix x32 ABI breakage
y2038: fix typo in powerpc vdso "LOPART"
y2038: allow disabling time32 system calls
y2038: itimer: change implementation to timespec64
y2038: move itimer reset into itimer.c
y2038: use compat_{get,set}_itimer on alpha
y2038: itimer: compat handling to itimer.c
y2038: time: avoid timespec usage in settimeofday()
y2038: timerfd: Use timespec64 internally
y2038: elfcore: Use __kernel_old_timeval for process times
y2038: make ns_to_compat_timeval use __kernel_old_timeval
y2038: socket: use __kernel_old_timespec instead of timespec
y2038: socket: remove timespec reference in timestamping
y2038: syscalls: change remaining timeval to __kernel_old_timeval
y2038: rusage: use __kernel_old_timeval
y2038: uapi: change __kernel_time_t to __kernel_old_time_t
y2038: stat: avoid 'time_t' in 'struct stat'
y2038: ipc: remove __kernel_time_t reference from headers
y2038: vdso: powerpc: avoid timespec references
...
As part of the cleanup of some remaining y2038 issues, I came to
fs/compat_ioctl.c, which still has a couple of commands that need support
for time64_t.
In completely unrelated work, I spent time on cleaning up parts of this
file in the past, moving things out into drivers instead.
After Al Viro reviewed an earlier version of this series and did a lot
more of that cleanup, I decided to try to completely eliminate the rest
of it and move it all into drivers.
This series incorporates some of Al's work and many patches of my own,
but in the end stops short of actually removing the last part, which is
the scsi ioctl handlers. I have patches for those as well, but they need
more testing or possibly a rewrite.

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"

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 generic ioremap support from Christoph Hellwig:
"This adds the remaining bits for an entirely generic ioremap and
iounmap to lib/ioremap.c. To facilitate that, it cleans up the giant
mess of weird ioremap variants we had with no users outside the arch
code.
For now just the three newest ports use the code, but there is more
than a handful others that can be converted without too much work.
Summary:
- clean up various obsolete ioremap and iounmap variants
- add a new generic ioremap implementation and switch csky, nds32 and
riscv over to it"

- PERAMAENT 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.

We failed to activate the mitigation for Spectre-RSB (Return Stack
Buffer, aka. ret2spec) on context switch, on CPUs prior to Power9
DD2.3.
That allows a process to poison the RSB (called Link Stack on Power
CPUs) and possibly misdirect speculative execution of another process.
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
exit path. A leak via that path has not been demonstrated, but we
believe it's at least theoretically possible.
This is the fix for CVE-2019-18660.

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 the
patches in here fall into two buckets:
- 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 depandancy 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.
All of these patches have been in linux-next for a long time with no
reported issues.

Core changes:
- Avoid taking direct references to device tree-supplied
device 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

Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for v5.5.
It is pretty much business as usual, the most interesting thing I
think is the pin controller for a new Intel chip called Lightning
Mountain, which is according to news reports some kind of embedded
network processor and what is surprising about it is that Intel have
decided to use device tree to describe the system rather than ACPI
that they have traditionally favored.

- Avoid taking direct references to device tree-supplied device
names: these may changed at runtime under certain circumstances to
kstrdup them.

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
we hit the WARN via alloc_netdev_mqs.

"The biggest changes in this cycle were:
- Make kcpustat vtime aware (Frederic Weisbecker)
- Rework the CFS load_balance() logic (Vincent Guittot)
- Misc cleanups, smaller enhancements, fixes.
The load-balancing rework is the most intrusive change: it replaces
the old heuristics that have become less meaningful after the
introduction of the PELT metrics, with a grounds-up load-balancing
algorithm.
As such it's not really an iterative series, but replaces the old
load-balancing logic with the new one. We hope there are no
performance regressions left - but statistically it's highly probable
that there *is* going to be some workload that is hurting from these
chnages. If so then we'd prefer to have a look at that workload and
fix its scheduling, instead of reverting the changes"

05b042a19443: ("x86/pti/32: Calculate the various PTI cpu_entry_area sizes correctly, make the CPU_ENTRY_AREA_PAGES assert precise")
'struct cpu_entry_area' has to be Kconfig invariant, so that we always
have a matching CPU_ENTRY_AREA_PAGES size.
This commit added a CONFIG_X86_IOPL_IOPERM dependency to tss_struct:
111e7b15cf10: ("x86/ioperm: Extend IOPL config to control ioperm() as well")
Which, if CONFIG_X86_IOPL_IOPERM is turned off, reduces the size of
cpu_entry_area by two pages, triggering the assert:
./include/linux/compiler.h:391:38: error: call to ‘__compiletime_assert_202’ declared with attribute error: BUILD_BUG_ON failed: (CPU_ENTRY_AREA_PAGES+1)*PAGE_SIZE != CPU_ENTRY_AREA_MAP_SIZE
Simplify the Kconfig dependencies and make cpu_entry_area constant

Pull x86 iopl updates from Ingo Molnar:
"This implements a nice simplification of the iopl and ioperm code that
Thomas Gleixner discovered: we can implement the IO privilege features
of the iopl system call by using the IO permission bitmap in
permissive mode, while trapping CLI/STI/POPF/PUSHF uses in user-space
if they change the interrupt flag.
This implements that feature, with testing facilities and related
cleanups"
[ "Simplification" may be an over-statement. The main goal is to avoid
the cli/sti of iopl by effectively implementing the IO port access
parts of iopl in terms of ioperm.
This may end up not workign well in case people actually depend on
cli/sti being available, or if there are mixed uses of iopl and
ioperm. We will see.. - Linus ]

This system call has been deprecated almost since it was introduced, and
in a survey of the linux distributions I can no longer find any of them
that enable CONFIG_SYSCTL_SYSCALL. The only indication that I can find
that anyone might care is that a few of the defconfigs in the kernel
enable CONFIG_SYSCTL_SYSCALL. However this appears in only 31 of 414
defconfigs in the kernel, so I suspect this symbols presence is simply
because it is harmless to include rather than because it is necessary.
As there appear to be no users of the sysctl system call, remove the
code. As this removes one of the few uses of the internal kernel mount
of proc I hope this allows for even more simplifications of the proc
filesystem.

Pull x86 mm updates from Ingo Molnar:
"The main changes in this cycle were:
- A PAT series from Davidlohr Bueso, which simplifies the memtype
rbtree by using the interval tree helpers. (There's more cleanups
in this area queued up, but they didn't make the merge window.)
- Also flip over CONFIG_X86_5LEVEL to default-y. This might draw in a
few more testers, as all the major distros are going to have
5-level paging enabled by default in their next iterations.
- Misc cleanups"
