Pull removal of in-kernel calls to syscalls from Dominik Brodowski:
"System calls are interaction points between userspace and the kernel.
Therefore, system call functions such as sys_xyzzy() or
compat_sys_xyzzy() should only be called from userspace via the
syscall table, but not from elsewhere in the kernel.
At least on 64-bit x86, it will likely be a hard requirement from
v4.17 onwards to not call system call functions in the kernel: It is
better to use use a different calling convention for system calls
there, where struct pt_regs is decoded on-the-fly in a syscall wrapper
which then hands processing over to the actual syscall function. This
means that only those parameters which are actually needed for a
specific syscall are passed on during syscall entry, instead of
filling in six CPU registers with random user space content all the
time (which may cause serious trouble down the call chain). Those
x86-specific patches will be pushed through the x86 tree in the near
future.
Moreover, rules on how data may be accessed may differ between kernel
data and user data. This is another reason why calling sys_xyzzy() is
generally a bad idea, and -- at most -- acceptable in arch-specific
code.
This patchset removes all in-kernel calls to syscall functions in the
kernel with the exception of arch/. On top of this, it cleans up the
three places where many syscalls are referenced or prototyped, namely
kernel/sys_ni.c, include/linux/syscalls.h and include/linux/compat.h"

Using the ksys_fadvise64_64() helper allows us to avoid the in-kernel
calls to the sys_fadvise64_64() syscall. The ksys_ prefix denotes that
this function is meant as a drop-in replacement for the syscall. In
particular, it uses the same calling convention as ksys_fadvise64_64().
Some compat stubs called sys_fadvise64(), which then just passed through
the arguments to sys_fadvise64_64(). Get rid of this indirection, and call
ksys_fadvise64_64() directly.
This patch is part of a series which removes in-kernel calls to syscalls.
On this basis, the syscall entry path can be streamlined. For details, see

Pull perf updates from Ingo Molnar:
"The main kernel side changes were:
- Modernize the kprobe and uprobe creation/destruction tooling ABIs:
The existing text based APIs (kprobe_events and uprobe_events in
tracefs), are naive, limited ABIs in that they require user-space
to clean up after themselves, which is both difficult and fragile
if the tool is buggy or exits unexpectedly. In other words they are
not really suited for modern, robust tooling.
So introduce a modern, file descriptor based ABI that does not have
these limitations: introduce the 'perf_kprobe' and 'perf_uprobe'
PMUs and extend the perf_event_open() syscall to create events with
a kprobe/uprobe attached to them. These [k,u]probe are associated
with this file descriptor, so they are not available in tracefs.
(Song Liu)
- Intel Cannon Lake CPU support (Harry Pan)
- Intel PT cleanups (Alexander Shishkin)
- Improve the performance of pinned/flexible event groups by using RB
trees (Alexey Budankov)
- Add PERF_EVENT_IOC_MODIFY_ATTRIBUTES which allows the modification
of hardware breakpoints, which new ABI variant massively speeds up
existing tooling that uses hardware breakpoints to instrument (and
debug) memory usage.
(Milind Chabbi, Jiri Olsa)
- Various Intel PEBS handling fixes and improvements, and other Intel
PMU improvements (Kan Liang)
- Various perf core improvements and optimizations (Peter Zijlstra)
- ... misc cleanups, fixes and updates.
There's over 200 tooling commits, here's an (imperfect) list of
highlights:
- 'perf annotate' improvements:
* Recognize and handle jumps to other functions as calls, which
improves the navigation along jumps and back. (Arnaldo Carvalho
de Melo)
* Add the 'P' hotkey in TUI annotation to dump annotation output
into a file, to ease e-mail reporting of annotation details.
(Arnaldo Carvalho de Melo)
* Add an IPC/cycles column to the TUI (Jin Yao)
* Improve s390 assembly annotation (Thomas Richter)
* Refactor the output formatting logic to better separate it into
interactive and non-interactive features and add the --stdio2
output variant to demonstrate this. (Arnaldo Carvalho de Melo)
- 'perf script' improvements:
* Add Python 3 support (Jaroslav Škarvada)
* Add --show-round-event (Jiri Olsa)
- 'perf c2c' improvements:
* Add NUMA analysis support (Jiri Olsa)
- 'perf trace' improvements:
* Improve PowerPC support (Ravi Bangoria)
- 'perf inject' improvements:
* Integrate ARM CoreSight traces (Robert Walker)
- 'perf stat' improvements:
* Add the --interval-count option (yuzhoujian)
* Add the --timeout option (yuzhoujian)
- 'perf sched' improvements (Changbin Du)
- Vendor events improvements :
* Add IBM s390 vendor events (Thomas Richter)
* Add and improve arm64 vendor events (John Garry, Ganapatrao
Kulkarni)
* Update POWER9 vendor events (Sukadev Bhattiprolu)
- Intel PT tooling improvements (Adrian Hunter)
- PMU handling improvements (Agustin Vega-Frias)
- Record machine topology in perf.data (Jiri Olsa)

Define vdso_start, vdso_end as array to avoid compile-time analysis error
for the case of built with CONFIG_FORTIFY_SOURCE.
and, since vdso_start, vdso_end are used in vdso.c only,
move extern-declaration from vdso.h to vdso.c.
If kernel is built with CONFIG_FORTIFY_SOURCE,
compile-time error happens at this code.
- if (memcmp(&vdso_start, "177ELF", 4))

We are still using custom SRAM code for some SoCs and are not marking
the PM code mapped to SRAM as read-only and executable after we're
done. With CONFIG_DEBUG_WX=y, we will get "Found insecure W+X mapping
at address" warning.
Let's fix this issue the same way as commit 728bbe75c82f ("misc: sram:
Introduce support code for protect-exec sram type") is doing for
drivers/misc/sram-exec.c.
On omap3, we need to restore SRAM when returning from off mode after
idle, so init time configuration is not enough.
And as we no longer have users for omap_sram_push_address() we can
make it static while at it.
Note that eventually we should be using sram-exec.c for all SoCs.

Mark noticed that the change to sibling_list changed some iteration
semantics; because previously we used group_list as list entry,
sibling events would always have an empty sibling_list.
But because we now use sibling_list for both list head and list entry,
siblings will report as having siblings.
Fix this with a custom for_each_sibling_event() iterator.

When we removed the inclusion of skeleton.dtsi from the device trees, we
broke booting for systems with bootloaders that aren't device tre aware.
This can be seen, for example, when appending the device tree blob to
the kernel image.
The reason booting broke was that the kernel lacked the device_type
label in the memory node. Add in a default memory node wth the
device_type. It can contain the memory address as the location is fixed
for each SoC generation, but the size needs to be added by the
bootloader or the board specific dts.

Commit 2b05f6ae1ee5 ("ARM: ux500: remove PMU IRQ bouncer")
deleted some code to bounce and work around the weird PMU
IRQs in the DB8500 ASIC, but did a semantic mistake:
since the auxdata was now unused, the call to
of_platform_populate() was removed, but this does not
work: the default platform population will only kick in
if .init_machine() is assigned NULL, and since the U8540
was still using the callback that was not the case.
Fix this by reinstating the call to of_platform_populate(),
but pass NULL as auxdata.

c53beb47f621 ("ARM: dts: NSP: Correct RAM amount for BCM958625HR board")
but it seems like we tripped over some poorly documented schematics.
The top-level page of the schematics says the board has 2GB, but when
you end-up scrolling to page 6, you see two chips of 4GBit (512MB) but
what the bootloader really initializes only 512MB, any attempt to use
more than that results in data aborts. Fix this again back to 512MB.

This stops the driver from trying to probe the ATA slave
interface. The vendor code enables the slave interface
but the driver in the vendor tree does not make use of
it.
Setting it to muxmode 0 disables the slave interface:
the hardware only has the master interface connected
to the one harddrive slot anyways.
Without this change booting takes excessive time, so it
is very annoying to end users.

It is not valid for orion5x to use mac_pton().
First of all, the orion5x buffer is not NULL terminated. mac_pton()
has no business operating on non-NULL terminated buffers because
only the caller can know that this is valid and in what manner it
is ok to parse this NULL'less buffer.
Second of all, orion5x operates on an __iomem pointer, which cannot
be dereferenced using normal C pointer operations. Accesses to
such areas much be performed with the proper iomem accessors.

Improve the DTS files by removing all the leading "0x" and zeros to fix the
following dtc warnings:
Warning (unit_address_format): Node /XXX unit name should not have leading "0x"
and
Warning (unit_address_format): Node /XXX unit name should not have leading 0s
Converted using the following command:
find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec sed -i -e "s/@\([0-9a-fA-FxX\.;:#]+\)\s*{/@\L\1 {/g" -e "s/@0x\(.*\) {/@\1 {/g" -e "s/@0+\(.*\) {/@\1 {/g" {} +^C
For simplicity, two sed expressions were used to solve each warnings separately.
To make the regex expression more robust a few other issues were resolved,
namely setting unit-address to lower case, and adding a whitespace before the
the opening curly brace:
https://elinux.org/Device_Tree_Linux#Linux_conventions
This will solve as a side effect warning:
Warning (simple_bus_reg): Node /XXX@<UPPER> simple-bus unit address format error, expected "<lower>"

A section type mismatch warning shows up when building with LTO,
since orion_ge00_mvmdio_bus_name was put in __initconst but not marked
const itself:
include/linux/of.h: In function 'spear_setup_of_timer':
arch/arm/mach-spear/time.c:207:34: error: 'timer_of_match' causes a section type conflict with 'orion_ge00_mvmdio_bus_name'
static const struct of_device_id timer_of_match[] __initconst = {

arch/arm/plat-orion/common.c:475:32: note: 'orion_ge00_mvmdio_bus_name' was declared here
static __initconst const char *orion_ge00_mvmdio_bus_name = "orion-mii";
^
As pointed out by Andrew Lunn, it should in fact be 'const' but not
'__initconst' because the string is never copied but may be accessed
after the init sections are freed. To fix that, I get rid of the
extra symbol and rewrite the initialization in a simpler way that
assigns both the bus_id and modalias statically.
I spotted another theoretical bug in the same place, where d->netdev[i]
may be an out of bounds access, this can be fixed by moving the device
assignment into the loop.
