Now that __user annotations are fixed for openrisc uaccess api's we can
add checking to the access_ok macro. This patch adds the __chk_user_ptr
check, on normal builds the added check is a nop.

The __user annotations in signal.c were mostly missing. The missing
annotations caused the warnings listed below. This patch fixes them up
by adding the __user annotations.

Since commit b48b2c3e5043 ("openrisc: use generic strnlen_user()
function") the macro __addr_ok is no longer used. It is safe to remove
so this patch removes it.

As suggested by Linus when reviewing commit 9cb2feb4d21d
("arch/openrisc: Fix issues with access_ok()") last year; making
__range_ok an inline function also fixes the used twice issue that the
commit was fixing. I agree it's a good cleanup. This patch addresses
that as I am currently working on the access_ok macro to fixup sparse
annotations in OpenRISC.

The OpenRISC user access functions put_user(), get_user() and
clear_user() were missing proper sparse annotations. This generated
warnings like the below.
This patch adds the annotations to fix the warnings.

Pull tracing updates from Steven Rostedt:
- The biggest news in that the tracing ring buffer can now time events
that interrupted other ring buffer events.
Before this change, if an interrupt came in while recording another
event, and that interrupt also had an event, those events would all
have the same time stamp as the event it interrupted.
Now, with the new design, those events will have a unique time stamp
and rightfully display the time for those events that were recorded
while interrupting another event.
- Bootconfig how has an "override" operator that lets the users have a
default config, but then add options to override the default.
- A fix was made to properly filter function graph tracing to the
ftrace PIDs. This came in at the end of the -rc cycle, and needs to
be backported.
- Several clean ups, performance updates, and minor fixes as well.

Trying to use ktls on a system with 32-bit userspace and 64-bit kernel
results in a EOPNOTSUPP message during sendmsg:
setsockopt(3, SOL_TLS, TLS_TX, …, 40) = 0
sendmsg(3, …, msg_flags=0}, 0) = -1 EOPNOTSUPP (Operation not supported)
The tls_sw implementation does strict flag checking and does not allow
the MSG_CMSG_COMPAT flag, which is set if the message comes in through
the compat syscall.
This patch adds MSG_CMSG_COMPAT to the flag check to allow the usage of
the TLS SW implementation on systems using the compat syscall path.
Note that the same check is present in the sendmsg path for the TLS
device implementation, however the flag hasn't been added there for lack
of testing hardware.

With commit b93df08ccda3 ("mptcp: explicitly track the fully

mptcp_sock_destruct() changes from TCP_SYN_RECV to TCP_ESTABLISHED.
As a result mptcp_sock_destruct() does not perform the proper
cleanup and inet_sock_destruct() will later emit a warn.
Address the issue updating the condition tested in mptcp_sock_destruct().

During diag self-tests we introduce long wait in the mptcp test
program to give the script enough time to access the sockets
dump.
Such wait is introduced after shutting down one sockets end. Since
commit 43b54c6ee382 ("mptcp: Use full MPTCP-level disconnect state
machine") if both sides shutdown the socket is correctly transitioned
into CLOSED status.
As a side effect some sockets are not dumped via the diag interface,
because the socket state (CLOSED) does not match the default filter, and
this cause self-tests instability.
Address the issue moving the above mentioned wait before shutting
down the socket.

Query the USB device's device tree node when looking for a MAC address.
The struct device embedded into the struct net_device does not have a
device tree node attached at all.
The reason why this went unnoticed is because the system where this was
tested was one of the few development units that had its OTP programmed,
as opposed to production systems where the MAC address is stored in a
separate EEPROM and is passed via device tree by the firmware.

Reproducing bug report here:
After hibernating and resuming, DPM is not enabled. This remains the case
even if you test hibernate using the steps here:
https://www.kernel.org/doc/html/latest/power/basic-pm-debugging.html
I debugged the problem, and figured out that in the file hardwaremanager.c,
in the function, phm_enable_dynamic_state_management(), the check
'if (!hwmgr->pp_one_vf && smum_is_dpm_running(hwmgr) && !amdgpu_passthrough(adev) && adev->in_suspend)'
returns true for the hibernate case, and false for the suspend case.
This means that for the hibernate case, the AMDGPU driver doesn't enable DPM
(even though it should) and simply returns from that function.
In the suspend case, it goes ahead and enables DPM, even though it doesn't need to.
I debugged further, and found out that in the case of suspend, for the
CIK/Hawaii GPUs, smum_is_dpm_running(hwmgr) returns false, while in the case of
hibernate, smum_is_dpm_running(hwmgr) returns true.
For CIK, the ci_is_dpm_running() function calls the ci_is_smc_ram_running() function,
which is ultimately used to determine if DPM is currently enabled or not,
and this seems to provide the wrong answer.
I've changed the ci_is_dpm_running() function to instead use the same method that
some other AMD GPU chips do (e.g Fiji), which seems to read the voltage controller.
I've tested on my R9 390 and it seems to work correctly for both suspend and
hibernate use cases, and has been stable so far.

Following commit d8f090dbeafd ("rtc: max77686: Do not allow interrupt to
fire before system resume"), RTC wake-ups stopped working on Jetson TX2
and Jetson Xavier platforms. The Jetson TX2 uses the max77620 PMIC and
the Jetson Xavier uses max20024 PMIC. Both of these PMICs have the same
max77620 RTC controller.
For the max77620 RTC, the variable 'rtc_irq_from_platform' is defined as
true in the max77686 driver and because of this the IRQ passed to the
max77686 driver for RTC is the PMIC IRQ and not the parent. Hence,
following commit d8f090dbeafd ("rtc: max77686: Do not allow interrupt to
fire before system resume"), for the max77620 the RTC IRQ within the
PMIC is now getting disabled on entry to suspend and unable to wake the
system up. Fix this by only disabling interrupts on entry to suspend
in the max77686 RTC driver, if the interrupt is the parent interrupt.

buffers
As trace_array_printk() used with not global instances will not add noise to
the main buffer, they are OK to have in the kernel (unlike trace_printk()).
This require the subsystem to create their own tracing instance, and the
trace_array_printk() only writes into those instances.
Add trace_array_init_printk() to initialize the trace_printk() buffers
without printing out the WARNING message.

Pull clk updates from Stephen Boyd:
"It looks like a smaller batch of clk updates this time around.
In the core framework we just have some minor tweaks and a debugfs
feature, so not much to see there. The driver updates are fairly well
split between AT91 and Qualcomm clk support. Adding those two drivers
together equals about 50% of the diffstat.
Otherwise, the big amount of work this time was on supporting
Broadcom's Raspberry Pi firmware clks.
Highlights:
Core:
- Document clk_hw_round_rate() so it gets some more use
- Remove unused __clk_get_flags()
- Add a prepare/enable debugfs feature similar to rate setting
New Drivers:
- Add support for SAMA7G5 SoC clks
- Enable CPU clks on Qualcomm IPQ6018 SoCs
- Enable CPU clks on Qualcomm MSM8996 SoCs
- GPU clk support for Qualcomm SM8150 and SM8250 SoCs
- Audio clks on Qualcomm SC7180 SoCs
- Microchip Sparx5 DPLL clk
- Add support for the new Renesas RZ/G2H (R8A774E1) SoC
Updates:
- Make defines for bcm63xx-gate clks to use in DT
- Support BCM2711 SoC firmware clks
- Add HDMI clks for BCM2711 SoCs
- Add RTC related clks on Ingenic SoCs
- Support USB PHY clks on Ingenic SoCs
- Support gate clks on BCM6318 SoCs
- RMU and DMAC/GPIO clock support for Actions Semi S500 SoCs
- Use poll_timeout functions in Rockchip clk driver
- Support Rockchip rk3288w SoC variant
- Mark mac_lbtest critical on Rockchip rk3188
- Add CAAM clock support for i.MX vf610 driver
- Add MU root clock support for i.MX imx8mp driver
- Amlogic g12: add neural network accelerator clock sources
- Amlogic meson8: remove critical flag for main PLL divider

Pull device mapper updates from Mike Snitzer:
- DM multipath locking fixes around m->flags tests and improvements to
bio-based code so that it follows patterns established by
request-based code.
- Request-based DM core improvement to eliminate unnecessary call to
blk_mq_queue_stopped().
- Add "panic_on_corruption" error handling mode to DM verity target.
- DM bufio fix to to perform buffer cleanup from a workqueue rather
than wait for IO in reclaim context from shrinker.
- DM crypt improvement to optionally avoid async processing via
workqueues for reads and/or writes -- via "no_read_workqueue" and
"no_write_workqueue" features. This more direct IO processing
improves latency and throughput with faster storage. Avoiding
workqueue IO submission for writes (DM_CRYPT_NO_WRITE_WORKQUEUE) is a
requirement for adding zoned block device support to DM crypt.
- Add zoned block device support to DM crypt. Makes use of
DM_CRYPT_NO_WRITE_WORKQUEUE and a new optional feature
(DM_CRYPT_WRITE_INLINE) that allows write completion to wait for
encryption to complete. This allows write ordering to be preserved,
which is needed for zoned block devices.
- Fix DM ebs target's check for REQ_OP_FLUSH.
- Fix DM core's report zones support to not report more zones than were
requested.
- A few small compiler warning fixes.
- DM dust improvements to return output directly to the user rather
than require they scrape the system log for output.

The vmstat pgrefill is useful together with pgscan and pgsteal stats to
measure the reclaim efficiency. However vmstat's pgrefill is not updated
consistently at system level. It gets updated for both global and memcg
reclaim however pgscan and pgsteal are updated for only global reclaim.
So, update pgrefill only for global reclaim. If someone is interested in
the stats representing both system level as well as memcg level reclaim,
then consult the root memcg's memory.stat instead of /proc/vmstat.

Move collapse_huge_page()'s mmget_still_valid() check into
khugepaged_test_exit() itself. collapse_huge_page() is used for anon THP
only, and earned its mmget_still_valid() check because it inserts a huge
pmd entry in place of the page table's pmd entry; whereas
collapse_file()'s retract_page_tables() or collapse_pte_mapped_thp()
merely clears the page table's pmd entry. But core dumping without mmap
lock must have been as open to mistaking a racily cleared pmd entry for a
page table at physical page 0, as exit_mmap() was. And we certainly have
no interest in mapping as a THP once dumping core.
