parisc: remove nargs from __SYSCALL
The __SYSCALL macro's arguments are system call number, system call entry name and number of arguments for the system call. Argument- nargs in __SYSCALL(nr, entry, nargs) is neither calculated nor used anywhere. So it would be better to keep the implementaion as __SYSCALL(nr, entry). This will unifies the implementation with some other architetures too. Signed-off-by: Firoz Khan <firoz.khan@linaro.org> Signed-off-by: Helge Deller <deller@gmx.de> |

parisc: Replace setup_irq() by request_irq()
request_irq() is preferred over setup_irq(). Invocations of setup_irq() occur after memory allocators are ready. Per tglx[1], setup_irq() existed in olden days when allocators were not ready by the time early interrupts were initialized. Hence replace setup_irq() by request_irq().

powerpc updates for 5.7
- A large series from Nick for 64-bit to further rework our exception vectors,
and rewrite portions of the syscall entry/exit and interrupt return in C. The
result is much easier to follow code that is also faster in general.
- Cleanup of our ptrace code to split various parts out that had become badly
intertwined with #ifdefs over the years.
- Changes to our NUMA setup under the PowerVM hypervisor which should
hopefully avoid non-sensical topologies which can lead to warnings from the
workqueue code and other problems.
- MAINTAINERS updates to remove some of our old orphan entries and update the
status of others.
- Quite a few other small changes and fixes all over the map.

There's not much to see in the core framework this time around. Instead the
majority of the diff is the normal collection of driver additions for new SoCs
and non-critical clk data fixes and updates. The framework must be middle aged.
The two biggest directories in the diffstat show that the Qualcomm and Unisoc
support added a handful of big drivers for new SoCs but that's not really the
whole story because those new drivers tend to add large numbers of lines of clk
data. There's a handful of AT91 clk drivers added this time around too and a
bunch of improvements to drivers like the i.MX driver. All around lots of
updates and fixes in various clk drivers which is good to see.
The core framework has only one real major change which has been baking in next
for the past couple months. It fixes the framework so that it stops caching a
clk's phase when the phase clk_op returns an error. Before this change we would
consider some negative errno as a phase and that just doesn't make sense.
Core:
- Don't show clk phase when it is invalid
New Drivers:
- Add support for Unisoc SC9863A clks
- Qualcomm SM8250 RPMh and MSM8976 RPM clks
- Qualcomm SM8250 Global Clock Controller (GCC) support
- Qualcomm SC7180 Modem Clock Controller (MSS CC) support
- EHRPWM's TimeBase clock(TBCLK) for TI AM654 SoCs
- Support PMC clks on at91sam9n12, at91rm9200, sama5d3, and at91sam9g45 SoCs
Updates:
- GPU GX GDSC support on Qualcomm sc7180
- Fixes and improvements for the Marvell MMP2/MMP3 SoC clk drivers
- A series from Anson to convert i.MX8 clock bindings to json-schema
- Update i.MX pll14xx driver to include new frequency entries for pll1443x table,
and return error for invalid PLL type
- Add missing of_node_put() call for a number of i.MX clock drivers
- Drop flag CLK_IS_CRITICAL from 'A53_CORE' mux clock, as we already
have the flag on its child cpu clock
- Fix a53 cpu clock for i.MX8 drivers to get it source from ARM PLL
via CORE_SEL slice, and source from A53 CCM clk root when we need to
change ARM PLL frequency. Thus, we can support core running above
1GHz safely
- Update i.MX pfdv2 driver to check zero rate and use determine_rate for
getting the best rate
- Add CLKO2 for imx8mm, SNVS clock for imx8mn, and PXP clock for imx7d
- Remove PMC clks from Tegra clk driver
- Improved clock/reset handling for the Renesas R-Car USB2 Clock Selector
- Conversion to json-schema of the Renesas CPG/MSSR DT bindings
- Add Crypto clocks on Renesas R-Car M3-W/W+, M3-N, E3, and D3
- Add RPC (QSPI/HyperFLASH) clocks on Renesas R-Car H3, M3-W/W+, and M3-N
- Update Amlogic audio clock gate hierarchy for meson8 and gxbb
- Update Amlogic g12a spicc clock sources
- Support for Ingenic X1000 TCU clks

New tracing features:
- The ring buffer is no longer disabled when reading the trace file.
The trace_pipe file was made to be used for live tracing and reading
as it acted like the normal producer/consumer. As the trace file
would not consume the data, the easy way of handling it was to just
disable writes to the ring buffer. This came to a surprise to the
BPF folks who complained about lost events due to reading.
This is no longer an issue. If someone wants to keep the old disabling
there's a new option "pause-on-trace" that can be set.
- New set_ftrace_notrace_pid file. PIDs in this file will not be traced
by the function tracer. Similar to set_ftrace_pid, which makes the
function tracer only trace those tasks with PIDs in the file, the
set_ftrace_notrace_pid does the reverse.
- New set_event_notrace_pid file. PIDs in this file will cause events
not to be traced if triggered by a task with a matching PID.
Similar to the set_event_pid file but will not be traced.
Note, sched_waking and sched_switch events may still be trace if
one of the tasks referenced by those events contains a PID that
is allowed to be traced.
Tracing related features:
- New bootconfig option, that is attached to the initrd file.
If bootconfig is on the command line, then the initrd file
is searched looking for a bootconfig appended at the end.
- New GPU tracepoint infrastructure to help the gfx drivers to get
off debugfs (acked by Greg Kroah-Hartman)
Other minor updates and fixes.

This is the bulk of GPIO development for the v5.7 kernel cycle.
Core and userspace API:
- The userspace API KFIFOs have been imoproved with locks that
do not block interrupts. This makes us better at getting
events to userspace without blocking or disturbing new events
arriving in the same time. This was reviewed by the KFIFO
maintainer Stefani. This is a generic improvement which
paves the road for similar improvements in other subsystems.
- We provide a new ioctl() for monitoring changes in the line
information, such as when multiple clients are taking lines
and giving them back, possibly reconfiguring them in the
process: we can now monitor that and not get stuck with stale
static information.
- An example tool 'gpio-watch' is provided to showcase this
functionality.
- Timestamps for events are switched to ktime_get_ns() which is
monotonic. We previously had a 'realtime' stamp which could
move forward and *backward* in time, which probably would just
cause silent bugs and weird behaviour. In the long run we
see two relevant timestamps: ktime_get_ns() or the timestamp
sometimes provided by the GPIO hardware itself, if that
exists.
- Device Tree overlay support for GPIO hogs. On systems that
load overlays, these overlays can now contain hogs, and will
then be respected.
- Handle pin control interaction with nonexisting pin ranges
in the GPIO library core instead of in the individual
drivers.
New drivers:
- New driver for the Mellanox BlueField 2 GPIO controller.
Driver improvements:
- Introduce the BGPIOF_NO_SET_ON_INPUT flag to the generic
MMIO GPIO library and use this flag in the MT7621 driver.
- Texas Instruments OMAP CPU power management improvements,
such as blocking of idle on pending GPIO interrupts.

Otherwise it fails, eg:

powerpc: Improve ppc_save_regs()
Make ppc_save_regs() a bit more useful:
- Set NIP to our caller rather rather than the caller's
caller (which is what we save to LR in the stack frame).
- Set SOFTE to the current irq soft-mask state rather than
uninitialised.
- Zero CFAR rather than leave it uninitialised.
In qemu, injecting a nmi to an idle CPU gives a nicer stack
trace (note NIP, IRQMASK, CFAR).

nvme-fc: Revert "add module to ops template to allow module references"
The original patch was to resolve the lldd being able to be unloaded
while being used to talk to the boot device of the system. However, the
end result of the original patch is that any driver unload while a nvme
controller is live via the lldd is now being prohibited. Given the module
reference, the module teardown routine can't be called, thus there's no
way, other than manual actions to terminate the controllers.

nvmet-rdma: fix bonding failover possible NULL deref
RDMA_CM_EVENT_ADDR_CHANGE event occur in the case of bonding failover on normal as well as on listening cm_ids. Hence this event will immediately trigger a NULL dereference trying to disconnect a queue for a cm_id that actually belongs to the port. To fix this we provide a different handler for the listener cm_ids that will defer a work to disable+(re)enable the port which essentially destroys and setups another listener cm_id Reported-by: Alex Lyakas <alex@zadara.com> Signed-off-by: Sagi Grimberg <sagi@grimberg.me> Reviewed-by: Max Gurtovoy <maxg@mellanox.com> Tested-by: Alex Lyakas <alex@zadara.com> Signed-off-by: Christoph Hellwig <hch@lst.de> |

net: dsa: mt7530: fix null pointer dereferencing in port5 setup
The 2nd gmac of mediatek soc ethernet may not be connected to a PHY
and a phy-handle isn't always available.
Unfortunately, mt7530 dsa driver assumes that the 2nd gmac is always
connected to switch port 5 and setup mt7530 according to phy address
of 2nd gmac node, causing null pointer dereferencing when phy-handle
isn't defined in dts.
This commit fix this setup code by checking return value of
of_parse_phandle before using it.

net: phy: micrel: kszphy_resume(): add delay after genphy_resume() before accessing PHY registers
After the power-down bit is cleared, the chip internally triggers a
global reset. According to the KSZ9031 documentation, we have to wait at
least 1ms for the reset to finish.
If the chip is accessed during reset, read will return 0xffff, while
write will be ignored. Depending on the system performance and MDIO bus
speed, we may or may not run in to this issue.
This bug was discovered on an iMX6QP system with KSZ9031 PHY and
attached PHY interrupt line. If IRQ was used, the link status update was
lost. In polling mode, the link status update was always correct.
The investigation showed, that during a read-modify-write access, the
read returned 0xffff (while the chip was still in reset) and
corresponding write hit the chip _after_ reset and triggered (due to the
0xffff) another reset in an undocumented bit (register 0x1f, bit 1),
resulting in the next write being lost due to the new reset cycle.
This patch fixes the issue by adding a 1...2 ms sleep after the
genphy_resume().

ARM: devicetree updates for v5.7
Most of the commits are for additional hardware support and minor fixes
for existing machines for all the usual platforms: qcom, amlogic, at91,
gemini, mediatek, ti, socfpga, i.mx, layerscape, uniphier, rockchip,
exynos, ux500, mvebu, tegra, stm32, renesas, sunxi, broadcom, omap,
and versatile.
The conversion of binding files to machine-readable yaml format
continues, along with fixes found during the validation.
Andre Przywara takes over maintainership for the old Calxeda Highbank
platform and provides a number of updates.
The OMAP2+ platforms see a continued move from platform data into
dts files, for many devices that relied on a mix of auxiliary data
in addition to the DT description
A moderate number of new SoCs and machines are added, here is a full
list:
- Two new Qualcomm SoCs with their evaluation boards: Snapdragon 865
(SM8250) is the current high-end phone chip, and IPQ6018 is a new
WiFi-6 router chip.

Pull ARM devicetree updates from Arnd Bergmann:
"Most of the commits are for additional hardware support and minor
fixes for existing machines for all the usual platforms: qcom,
amlogic, at91, gemini, mediatek, ti, socfpga, i.mx, layerscape,
uniphier, rockchip, exynos, ux500, mvebu, tegra, stm32, renesas,
sunxi, broadcom, omap, and versatile.
The conversion of binding files to machine-readable yaml format
continues, along with fixes found during the validation. Andre
Przywara takes over maintainership for the old Calxeda Highbank
platform and provides a number of updates.
The OMAP2+ platforms see a continued move from platform data into dts
files, for many devices that relied on a mix of auxiliary data in
addition to the DT description
A moderate number of new SoCs and machines are added, here is a full
list:
- Two new Qualcomm SoCs with their evaluation boards: Snapdragon 865
(SM8250) is the current high-end phone chip, and IPQ6018 is a new
WiFi-6 router chip.
- Mediatek MT8516 application processor SoC for voice assistants,
along with the "pumpkin" development board
