Prefer _THIS_IP_ defined in linux/kernel.h.
Most definitions of current_text_addr were the same as _THIS_IP_, but
a few archs had inline assembly instead.
This patch removes the final call site of current_text_addr, making all
of the definitions dead code.

When building with clang (8 trunk, 7.0 release) the frame size limit is
hit:
arch/powerpc/xmon/xmon.c:452:12: warning: stack frame size of 2576
bytes in function 'xmon_core' [-Wframe-larger-than=]
Some investigation by Naveen indicates this is due to clang saving the
addresses to printf format strings on the stack.
While this issue is investigated, bump up the frame size limit for xmon
when building with clang.

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing updates from Steven Rostedt:
"The biggest change here is the updates to kprobes
Back in January I posted patches to create function based events.
These were the events that you suggested I make to allow developers to
easily create events in code where no trace event exists. After
posting those changes for review, it was suggested that we implement
this instead with kprobes.
The problem with kprobes is that the interface is too complex and
needs to be simplified. Masami Hiramatsu posted patches in March and
I've been playing with them a bit. There's been a bit of clean up in
the kprobe code that was inspired by the function based event patches,
and a couple of enhancements to the kprobe event interface.
- If the arch supports it (we added support for x86), you can place a
kprobe event at the start of a function and use $arg1, $arg2, etc
to reference the arguments of a function. (Before you needed to
know what register or where on the stack the argument was).
- The second is a way to see array of events. For example, if you
reference a mac address, you can add:
echo 'p:mac ip_rcv perm_addr=+574($arg2):x8[6]' > kprobe_events
And this will produce:
mac: (ip_rcv+0x0/0x140) perm_addr={0x52,0x54,0x0,0xc0,0x76,0xec}
Other changes include
- Exporting trace_dump_stack to modules
- Have the stack tracer trace the entire stack (stop trying to remove
tracing itself, as we keep removing too much).
- Added support for SDT in uprobes"
[ SDT - "Statically Defined Tracing" are userspace markers for tracing.
Let's not use random TLA's in explanations unless they are fairly
well-established as generic (at least for kernel people) - Linus ]

The numa_emulation() routine in the 'uniform' case walks through all the
physical 'memblk' instances and divides them into N emulated nodes with
split_nodes_size_interleave_uniform(). As each physical node is consumed it
is removed from the physical memblk array in the numa_remove_memblk_from()
helper.
Since split_nodes_size_interleave_uniform() handles advancing the array as
the 'memblk' is consumed it is expected that the base of the array is
always specified as the argument.
Otherwise, on multi-socket (> 2) configurations the uniform-split
capability can generate an invalid numa configuration leading to boot
failures with signatures like the following:
rcu: INFO: rcu_sched detected stalls on CPUs/tasks:

Pull ARM SoC platform updates from Arnd Bergmann:
"A couple of platforms change hands in the MAINTAINERS file:
- Linus Walleij lists himself for the ARM Reference platforms:
versatile, vexpress, integrator and realview. He has been the main
contributor for these for a while, and makes it official now.
- Vladimir Zapolskiy takes over the LPC18xx platform from Joachim
Eastwood
- Manivannan Sadhasivam becomes a secondary maintainer for the
Actions Semi machines
- Nicolas Ferre lists updates the MAINTAINER listing for the AT91
platform: Ludovic Desroches is now a co-maintainer for the
platform, and several other people (Claudiu Beznea, Cristian
Birsan, Eugen Hristev, Codrin Ciubotariu) take over individual
device drivers.
Thanks everyone for working on this, and welcome to the new
maintainers!
The "virt" platform on qemy or kvm can now be used in big-endian mode
without additional tricks, thanks to Jason Donenfeld.
Once again, we gain support for another NXP i.MX6 variant, this time
it's the i.MX 6ULZ 32-bit single-core version.
On arm64, we add support for two SoCs from Renesas: RZ/G2E (r8a774c0)
and RZ/G2M (r8a774a1). These are described as microcontrollers on the
manufacturer website, but appear to be rather powerful. The RZ/G2M is
used on the reference board for the CIP Super Long Term Support (SLTS)

Pull ARM SoC driver updates from Arnd Bergmann:
"The most noteworthy SoC driver changes this time include:
- The TEE subsystem gains an in-kernel interface to access the TEE
from device drivers.
- The reset controller subsystem gains a driver for the Qualcomm
Snapdragon 845 Power Domain Controller.
- The Xilinx Zynq platform now has a firmware interface for its
platform management unit. This contains a firmware "ioctl"
interface that was a little controversial at first, but the version
we merged solved that by not exposing arbitrary firmware calls to
user space.
- The Amlogic Meson platform gains a "canvas" driver that is used for
video processing and shared between different high-level drivers.
The rest is more of the usual, mostly related to SoC specific power
management support and core drivers in drivers/soc:
- Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new
features related to power and reset control.
- The Mediatek mt8183 and mt6765 SoC platforms gain support for their
respective power management chips.
- A new driver for NXP i.MX8, which need a firmware interface for
power management.
- The SCPI firmware interface now contains support estimating power
usage of performance states
- The NVIDIA Tegra "pmc" driver gains a few new features, in
particular a pinctrl interface for configuring the pads.
- Lots of small changes for Qualcomm, in particular the "smem" device
driver.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC device tree updates from Arnd Bergmann:
"There are close to 800 indivudal changesets in this branch again,
which feels like a lot. There are particularly many changes for the
NVIDIA Tegra platform this time, in fact more than it has seen in the
two years since the v4.9 merge window. Aside from this, it's been
fairly normal, with lots of changes going into Renesas R-CAR, NXP
i.MX, Allwinner Sunxi, Samsung Exynos, and TI OMAP.
Most of the changes are for adding new features into existing boards,
for brevity I'm only mentioning completely new machines and SoCs here.
For the first time I think we have (slightly) more new 64-bit hardware
than 32-bit:
Two boards get added for TI OMAP: Moxa UC-2101 is an industrial
computer, see https://www.moxa.com/product/UC-2100.htm; GTA04A5 is a
minor variation of the motherboards of the GTA04 phone, see
https://shop.goldelico.com/wiki.php?page=GTA04A5
Clearfog is a nice little board for quad-core Marvell Armada 8040
network processor, see
https://www.solid-run.com/marvell-armada-family/clearfog-gt-8k/
Two additional server boards come with the Aspeed baseboard management
controllers: Stardragon4800 is an arm64 reference platform made by HXT
(based on Qualcomm's server chips), and TiogaPass is an Open Compute
mainboard with x86 CPUs. Both use the ARM11 based AST2500 chips in the
BMC.
NXP i.MX usually sees a lot of new boards each release. This time
there we only add one minor variant: ConnectCore 6UL SBC Pro uses the
same SoM design as the ConnectCore 6UL SBC Express added later.
However, there is a new chip, the i.MX6ULZ, which is an even smaller
variant of the i.MX6ULL, with features removed. There is also support
for the reference board design, the i.MX6ULZ 14x14 EVK.
A new Raspberry Pi variant gets added, this one is the CM3 compute
module based on bcm2837, it was launched in early 2017 but only now
added to the kernel, both as 32-bit and as 64-bit files, as we tend to
do for Raspberry Pi.
On the Allwinner side, everything is again about cheap development
boards, usually of the "Fruit Pi" variety. The new ones this time are:
- Orange Pi Zero Plus2: http://www.orangepi.org/OrangePiZeroPlus2/
- Orange Pi One Plus: http://www.orangepi.org/OrangePiOneplus/
- Pine64 LTS: https://www.pine64.org/?product=pine-a64-lts
- Banana Pi M2+ H5: http://www.banana-pi.org/m2plus.html
The last one of these is now a 64-bit version of the earlier Banana Pi
M2+ H3, with the same board layout.
Similarly, for Rockchips, get get another variant of the 32-bit Asus
Tinker board, the model 'S' based on rk3288, and three now boards
based on the popular RK3399 chip:
- ROC-RK3399-PC: https://libre.computer/products/boards/roc-rk3399-pc/
- Rock960: https://www.96boards.org/product/rock960/
- RockPro64: https://www.pine64.org/?page_id=61454
These are all quite powerful boards with lots of RAM and I/O, and the
RK3399 is the same chip used in several Chromebooks. Finally, we get
support for the PX30 (aka rk3326) chip, which is based on the low-end
64-bit Cortex-A35 CPU core. So far, only the evaluation board is
supported.
One more Banana Pi is added with a Mediatek chip: Banana Pi R64 is
based on the MT7622 WiFi router platform, and the first product I've
seen with a 64-bit Mediatek chip in that market:
http://www.banana-pi.org/r64.html
For HiSilicon, we gain support for the Hi3670 SoC and HiKey 370
development board, which are similar to the Hi3660 and Hikey 360
respectively, but add support for an NPU.
Amlogic gets initial support for the Meson-G12A chip (S905D2), another
quad-core Cortex-A53 SoC, and its evaluation platform. On the 32-bit
side, we gain support for an actual end-user product, the Endless
Computers Endless Mini based on Meson8b (S805), see
https://endlessos.com/computers/
Qualcomm adds support for their MSM8998 SoC and evaluation platform.
This chip is commonly known as the Snapdragon 835, and is used in
high-end phones as well as low-end laptops.
For Renesas, a very bare support for the r8a774a1 (RZ/G2M) is added,
but no boards for this one. However, we do add boards for the
previously added r8a77965 (R-Car M3-N): the M3NULCB Kingfisher and the
M3NULCB Starter Kit Pro.
While we have lots of DT changes for NVIDIA to update the existing
files, the only board that gets added is the Toradex Colibri T20 on
Colibri Evaluation Board for the old Tegra2.
Synaptics add support for their AS370 SoC, which is part of the
(formerly Marvell) Berlin line of set-top-box chips used e.g. in the
various Google Chromecast. Only the .dtsi gets added at this point, no
actual machines"

32bit UML used to define PTRACE_SYSEMU and PTRACE_SYSEMU_SINGLESTEP
own its own because many years ago not all libcs had these request codes
in their UAPI.
These days PTRACE_SYSEMU/_SINGLESTEP is well known and part of glibc
and our own define becomes problematic.
With change c48831d0eebf ("linux/x86: sync sys/ptrace.h with Linux 4.14
[BZ #22433]") glibc turned PTRACE_SYSEMU/_SINGLESTEP into a enum and
UML failed to build.
Let's drop our define and rely on the fact that every libc has
PTRACE_SYSEMU/_SINGLESTEP.

The WARN_ON_ONCE(__read_cr3() != build_cr3()) in switch_mm_irqs_off()
triggers every once in a while during a snapshotted system upgrade.
The warning triggers since commit decab0888e6e ("x86/mm: Remove
preempt_disable/enable() from __native_flush_tlb()"). The callchain is:
get_page_from_freelist() -> post_alloc_hook() -> __kernel_map_pages()
with CONFIG_DEBUG_PAGEALLOC enabled.
Disable preemption during CR3 reset / __flush_tlb_all() and add a comment
why preemption has to be disabled so it won't be removed accidentaly.
Add another preemptible() check in __flush_tlb_all() to catch callers with
enabled preemption when PGE is enabled, because PGE enabled does not
trigger the warning in __native_flush_tlb(). Suggested by Andy Lutomirski.

Commit 5c83511bdb9832 ("x86/paravirt: Use a single ops structure")
introduced a regression for out-of-tree modules using spinlocks, as
pv_lock_ops was exported via EXPORT_SYMBOL(), while the new pv_ops
structure now containing the pv lock operations is exported via
EXPORT_SYMBOL_GPL().
Change that by using EXPORT_SYMBOL(pv_ops).

We use buildroot as our CI-test enviornment. "LTP, Lmbench ..." will
be tested for every commit. See here for more details:
https://gitlab.com/c-sky/buildroot/pipelines
We'll continouslly improve csky subsystem in future"
Arnd acks, and adds the following notes:
"I did a thorough review of the ABI, which as usual mainly consists of
spotting any files that don't use the asm-generic ABI itself, and
having it changed to it matches exactly what we do on other new
architectures.
I also looked at every other patch and commented on maybe half of them
where I saw something that did not quite seem right. Others have
reviewed specific patches in greater depth. I'm sure that one could
fine more of the minor details, but as long as they are not ABI
relevant, they can be fixed later.
The only patch that is part of the ABI and that nobody reviewed is the
signal handling. This is one of the areas I never worked on in much
detail. I did not see anything wrong with it, but I also don't know
what the problems with the other architectures are here, and we seem
to be hitting issues occasionally, and we never managed to generalize
this enough for new architectures to have a trivial implementation.
I was originally hoping that we could have the 64-bit time_t
interfaces ready in time to completely drop the 32-bit ones, but that
did not happen. We might still remove them in the next merge window
depending on whether the libc upstream people prefer to keep them or
not.
One more general comment: I think this may well be the last new CPU
architecture we ever add to the kernel. Both nds32 and c-sky are made
by companies that also work on risc-v, and generally speaking risc-v
seems to be killing off any of the minor licensable instruction set
projects, just like ARM has mostly killed off the custom
vendor-specific instruction sets already.
If we add another architecture in the future, it may instead be
something like the LLVM bitcode or WebAssembly, who knows?"
To which Geert Uytterhoeven pipes in about another architecture still in
the pipeline: Kalray MPPA.

handle_stack_overflow() can only be called from two places (kernel/traps.c

Pull XArray conversion from Matthew Wilcox:
"The XArray provides an improved interface to the radix tree data
structure, providing locking as part of the API, specifying GFP flags
at allocation time, eliminating preloading, less re-walking the tree,
more efficient iterations and not exposing RCU-protected pointers to
its users.
This patch set
1. Introduces the XArray implementation
2. Converts the pagecache to use it
3. Converts memremap to use it
The page cache is the most complex and important user of the radix
tree, so converting it was most important. Converting the memremap
code removes the only other user of the multiorder code, which allows
us to remove the radix tree code that supported it.
I have 40+ followup patches to convert many other users of the radix
tree over to the XArray, but I'd like to get this part in first. The
other conversions haven't been in linux-next and aren't suitable for
applying yet, but you can see them in the xarray-conv branch if you're
interested"

I believe the following change will fix the cache/TLB inconsistency
observed by Meelis. After changing the page table entries, we need to
flush the cache and TLB to ensure that we don't have any stale PTE
values in the cache or TLB.
The alternative patching is done after all CPUs are running. Thus, we
need to flush the whole cache and TLB.
I included the init section in the range modified by map_pages as
suggested by Helge. Some routines in the init section may require
patching.
