[PATCH AUTOSEL 5.10 02/29] arm64: Do not forget syscall when starting a new thread.

[Sasha Levin]

From: Francis Laniel <flaniel@linux.microsoft.com>

[ Upstream commit de6921856f99c11d3986c6702d851e1328d4f7f6 ]

Enable tracing of the execve*() system calls with the
syscalls:sys_exit_execve tracepoint by removing the call to
forget_syscall() when starting a new thread and preserving the value of
regs->syscallno across exec.

[PATCH AUTOSEL 5.10 03/29] arm64: fix oops in concurrently setting insn_emulation sysctls

[Sasha Levin]

From: haibinzhang (张海斌) <haibinzhang@tencent.com>

[ Upstream commit af483947d472eccb79e42059276c4deed76f99a6 ]

emulation_proc_handler() changes table->data for proc_dointvec_minmax
and can generate the following Oops if called concurrently with itself:

 | Unable to handle kernel NULL pointer dereference at virtual address 0000000000000010
 | Internal error: Oops: 96000006 [#1] SMP
 | Call trace:
 | update_insn_emulation_mode+0xc0/0x148
 | emulation_proc_handler+0x64/0xb8
 | proc_sys_call_handler+0x9c/0xf8
 | proc_sys_write+0x18/0x20

 | el0_svc_common.constprop.0+0x7c/0x1c0
 | el0_svc_handler+0x2c/0xa0
 | el0_svc+0x8/0x200

To fix this issue, keep the table->data as &insn->current_mode and
use container_of() to retrieve the insn pointer. Another mutex is
used to protect against the current_mode update but not for retrieving
insn_emulation as table->data is no longer changing.

[PATCH AUTOSEL 5.10 16/29] ARM: dts: BCM5301X: Add DT for Meraki MR26

[Sasha Levin]

From: Christian Lamparter <chunkeey@gmail.com>

[ Upstream commit 935327a73553001f8d81375c76985d05f604507f ]

Meraki MR26 is an EOL wireless access point featuring a
PoE ethernet port and two dual-band 3x3 MIMO 802.11n
radios and 1x1 dual-band WIFI dedicated to scanning.

Thank you Amir for the unit and PSU.

Hardware info:
SOC   : Broadcom BCM53015A1KFEBG (dual-core Cortex-A9 CPU at 800 MHz)
RAM   : SK Hynix Inc. H5TQ1G63EFR, 1 GBit DDR3 SDRAM = 128 MiB
NAND  : Spansion S34ML01G100TF100, 1 GBit SLC NAND Flash = 128 MiB
ETH   : 1 GBit Ethernet Port - PoE (TPS23754 PoE Interface)
WIFI0 : Broadcom BCM43431KMLG, BCM43431 802.11 abgn (3x3:3)
WIFI1 : Broadcom BCM43431KMLG, BCM43431 802.11 abgn (3x3:3)
WIFI2 : Broadcom BCM43428 "Air Marshal" 802.11 abgn (1x1:1)
BUTTON: One reset key behind a small hole next to the Ethernet Port
LEDS  : One amber (fault), one white (indicator) LED, separate RGB-LED
MISC  : Atmel AT24C64 8KiB EEPROM i2c
      : Ti INA219 26V, 12-bit, i2c output current/voltage/power monitor

SERIAL:
      WARNING: The serial port needs a TTL/RS-232 3V3 level converter!
      The Serial setting is 115200-8-N-1. The board has a populated
      right angle 1x4 0.1" pinheader.
      The pinout is: VCC (next to J3, has the pin 1 indicator), RX, TX, GND.

Odd stuff:

- uboot does not support lzma compression, but gzip'd uImage/DTB work.
- uboot claims to support FIT, but fails to pass the DTB to the kernel.
  Appending the dtb after the kernel image works.
- RGB-controller is supported through an external userspace program.
- The ubi partition contains a "board-config" volume. It stores the
  MAC Address (0x66 in binary) and Serial No. (0x7c alpha-numerical).
- SoC's temperature sensor always reports that it is on fire.
  This causes the system to immediately shutdown! Looking at reported
  "418 degree Celsius" suggests that this sensor is not working.

WIFI:
b43 is able to initialize all three WIFIs @ 802.11bg.

[PATCH AUTOSEL 5.10 18/29] ARM: OMAP2+: display: Fix refcount leak bug

[Sasha Levin]

From: Liang He <windhl@126.com>

[ Upstream commit 50b87a32a79bca6e275918a711fb8cc55e16d739 ]

In omapdss_init_fbdev(), of_find_node_by_name() will return a node
pointer with refcount incremented. We should use of_node_put() when
it is not used anymore.

[PATCH AUTOSEL 5.10 24/29] arm64: dts: allwinner: a64: orangepi-win: Fix LED node name

[Sasha Levin]

From: Samuel Holland <samuel@sholland.org>

[ Upstream commit b8eb2df19fbf97aa1e950cf491232c2e3bef8357 ]

"status" does not match any pattern in the gpio-leds binding. Rename the
node to the preferred pattern. This fixes a `make dtbs_check` error.

[PATCH AUTOSEL 5.10 25/29] ARM: shmobile: rcar-gen2: Increase refcount for new reference

[Sasha Levin]

From: Liang He <windhl@126.com>

[ Upstream commit 75a185fb92e58ccd3670258d8d3b826bd2fa6d29 ]

In rcar_gen2_regulator_quirk(), for_each_matching_node_and_match() will
automatically increase and decrease the refcount.  However, we should
call of_node_get() for the new reference created in 'quirk->np'.
Besides, we also should call of_node_put() before the 'quirk' being
freed.
