These changes update the ipc sysctls so that they are fundamentally
per ipc namespace. Previously these sysctls depended upon a hack to simulate being per ipc namespace by looking up the ipc namespace in read or write. With this set of changes the ipc sysctls are registered per ipc namespace and open looks up the ipc namespace. Not only does this series of changes ensure the traditional binding at open time happens, but it sets a foundation for being able to relax the permission checks to allow a user namspace root to change the ipc sysctls for an ipc namespace that the user namespace root requires. To do this requires the ipc namespace to be known at open time. These changes were sent for v5.18[1] but were dropped because some additional cleanups were requested. Linus has given his nod[2] to the cleanups so I hope enough cleanups are present this time.

Add partial Loongarch architecture code
This is the majority of the loongarch architecture code, including
the final system call interface and all core functionality.
It still misses three sets of peripheral but vital patches to add
support for other subsystems, which have yet to pass review:
- The drivers/firmware/efi stub for booting from a standard UEFI
firmware implementation. Both the original custom boot interface
and a draft implementation of the EFI stub did not make it, so
it is currently impossible to boot the kernel, until the
loongarch specific portions get accepted into the UEFI subsystem
- The drivers/irqchip/irq-loongson-*.c drivers are shared with the
the MIPS port, but currently lack support for ACPI based booting,
which will get merged through the irqchip subsystem.
- Similarly, the drivers/pci/controller/pci-loongson.c needs to be
modified for ACPI support, which will be merged through the
PCI subsystem.
While the port cannot actually be used before all the above are
merged, having it in 5.19 helps to establish the user space ABI
for the libc ports to build on, and to help any treewide changes
in the mainline kernel get applied here as well. A gcc-12 based
tool chains for build testing is now included in
https://mirrors.edge.kernel.org/pub/tools/crosstool/.
Original description from Huacai Chen at
https://lore.kernel.org/lkml/20220603072053.35005-1-chenhuacai@loongson.cn/:

RISC-V Patches for the 5.19 Merge Window, Part 2
This is mostly some DT updates, but also a handful of cleanups and some
fixes. The most user-visible of those are:
* A device tree for the Sundance Polarberry, along with a handful of

* The memfd_secret syscall number is now visible to userspace,

followed shortly after the sv48 patches but I missed.

driver core: Fix wait_for_device_probe() & deferred_probe_timeout interaction
Mounting NFS rootfs was timing out when deferred_probe_timeout was non-zero [1]. This was because ip_auto_config() initcall times out waiting for the network interfaces to show up when deferred_probe_timeout was non-zero. While ip_auto_config() calls wait_for_device_probe() to make sure any currently running deferred probe work or asynchronous probe finishes, that wasn't sufficient to account for devices being deferred until deferred_probe_timeout.

ARM: omap1: enable multiplatform
With all the header files out of the way, and the clock driver converted to the common framework, nothing stops us from building OMAP together with the other platforms. As usual, the decompressor support is a victim here, and is only available when CONFIG_DEBUG_LL is configured for the particular board.

ARM: OMAP1: clock: Convert to CCF
OMAP1 still uses its own implementation of standard clock API defined in include/linux/clk.h. Internals of that implementation are not visible outside OMAP1 directory. As a consequence, device drivers are not able to register clocks potentially provided by peripheral devices. Drop OMAP1 implementation of the clock API and enable common clock framework. Modify the remaining low level code to be compatible with clock provider API and register the clocks with CCF. Move initialisation of clocks to omap1_timer_init() to avoid memory allocation issues at early setup phase from where omap1_init_early() is called. Register the clocks after initialization of clock I/O registers, local clock pointers used by OMAP1 clock ops, and local .rate fields of clocks with no local implementation of .recalc ops, so CCF structures are populated with correct data during clock registration. Instead of enabling some of the registered clocks, flag them for CCF as critical. Introduce .is_enabled op using code that verifies hardware status of clock enablement, split out from implementation of .disable_unused op, so the latter is actually called by CCF for not requested but hardware enabled clocks. Add .round_rate ops where missing so .set_rate ops are called by CCF as expected. Since CCF allows parallel execution of .enable/.disable and .set_rate ops, protect registers shared among those groups of ops from concurrent access with spinlocks. Drop local debugfs support in favor of that provided by CCF. v2: flag tc2_ck as CLK_IS_CRITICAL (Aaro) v3: rebase on top of soc/omap1-multiplatform-5.18, - drop no longer needed includes from arch/arm/mach-omap1/io.c Signed-off-by: Janusz Krzysztofik <jmkrzyszt@gmail.com> Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de> |

Driver core changes for 5.19-rc1
Here is the set of driver core changes for 5.19-rc1.
Note, I'm not really happy with this pull request as-is, see below for
details, but overall this is all good for everything but a small set of
systems, which we have a fix for already.
Lots of tiny driver core changes and cleanups happened this cycle,
but the two major things were:
- firmware_loader reorganization and additions including the
ability to have XZ compressed firmware images and the ability
for userspace to initiate the firmware load when it needs to,
instead of being always initiated by the kernel. FPGA devices
specifically want this ability to have their firmware changed
over the lifetime of the system boot, and this allows them to
work without having to come up with yet-another-custom-uapi
interface for loading firmware for them.
- physical location support added to sysfs so that devices that
know this information, can tell userspace where they are
located in a common way. Some ACPI devices already support
this today, and more bus types should support this in the
future.
Smaller changes included:
- driver_override api cleanups and fixes
- error path cleanups and fixes
- get_abi script fixes
- deferred probe timeout changes.
It's that last change that I'm the most worried about. It has been
reported to cause boot problems for a number of systems, and I have a
tested patch series that resolves this issue. But I didn't get it
merged into my tree before 5.18-final came out, so it has not gotten any
linux-next testing.
I'll send the fixup patches (there are 2) as a follow-on series to this
pull request if you want to take them directly, _OR_ I can just revert
the probe timeout changes and they can wait for the next -rc1 merge
cycle. Given that the fixes are tested, and pretty simple, I'm leaning
toward that choice. Sorry this all came at the end of the merge window,
I should have resolved this all 2 weeks ago, that's my fault as it was
in the middle of some travel for me.
All have been tested in linux-next for weeks, with no reported issues
other than the above-mentioned boot time outs.

USB / Thunderbolt changes for 5.19-rc1
Here is the "big" set of USB and Thunderbolt driver changes for
5.18-rc1. For the most part it's been a quiet development cycle for the
USB core, but there are the usual "hot spots" of development activity.
Included in here are:
- Thunderbolt driver updates:
- fixes for devices without displayport adapters
- lane bonding support and improvements
- other minor changes based on device testing
- dwc3 gadget driver changes. It seems this driver will never
be finished given that the IP core is showing up in zillions
of new devices and each implementation decides to do something
different with it...
- uvc gadget driver updates as more devices start to use and
rely on this hardware as well
- usb_maxpacket() api changes to remove an unneeded and unused
parameter.
- usb-serial driver device id updates and small cleanups
- typec cleanups and fixes based on device testing
- device tree updates for usb properties
- lots of other small fixes and driver updates.
All of these have been in linux-next for weeks with no reported
problems.

TTY / Serial driver changes for 5.19-rc1
Here is the big set of tty and serial driver updates for 5.19-rc1.
Lots of tiny cleanups in here, the major stuff is:
- termbit cleanups and unification by Ilpo. A much needed
change that goes a long way to making things simpler for all
of the different arches
- tty documentation cleanups and movements to their own place in
the documentation tree
- old tty driver cleanups and fixes from Jiri to bring some
existing drivers into the modern world
- RS485 cleanups and unifications to make it easier for
individual drivers to support this mode instead of having to
duplicate logic in each driver
- Lots of 8250 driver updates and additions
- new device id additions
- n_gsm continued fixes and cleanups
- other minor serial driver updates and cleanups
All of these have been in linux-next for weeks with no reported issues.

Staging driver updates for 5.19-rc1
Here is the big set of staging driver updates for 5.19-rc1.
Lots of forward progress happened this development cycle, one driver
(wfx wireless driver) got merged into the real portion of the kernel,
and another one (unisys) was removed as no one is around anymore to take
care of it and no one has the hardware. Combined with loads of tiny
driver cleanups overall we removed 13k lines of code from the tree, a
nice improvement.
Other than the wfx and unisys driver changes the major points of this
merge is:
- r8188eu driver cleanups. So many cleanups. It's amazing just
how many things have been cleaned up here, and yet, how many
remain to go. Lots of work happened here, and it doesn't look
to slow down any time soon.
- other wifi driver cleanups. Not as many as the r8188eu
driver, but still pretty impressive from a janitorial point of
view.
- bcm2853 driver cleanups
- other very minor driver cleanups
All of these have been in the linux-next tree for weeks with no reported
issues.
Note, you will have a merge conflict in the
drivers/net/wireless/silabs/wfx/sta.c file, please just take the change
that came in from the wifi tree. We thought as I had pulled the same
merge point from the wifi developers this type of conflict wouldn't have
happened, but for some reason git flags it as something to pay attention
to and couldn't resolve it itself.

dt-bindings: memory-controllers: ingenic: Split out child node properties
Binding schemas which define child node properties such as memory controllers with timing properties need a separate schema which can be referenced from child device schemas. This is necessary for unevaluatedProperties checks to work properly. Move the ingenic,nemc child properties to its own file and reference from ingenic,nand.yaml which describes a child NAND controller.

LoongArch: Add Non-Uniform Memory Access (NUMA) support
Add Non-Uniform Memory Access (NUMA) support for LoongArch. LoongArch has 48-bit physical address, but the HyperTransport I/O bus only support 40-bit address, so we need a custom phys_to_dma() and dma_to_phys() to extract the 4-bit node id (bit 44~47) from Loongson-3's 48-bit physical address space and embed it into 40-bit. In the 40-bit dma address, node id offset can be read from the LS7A_DMA_CFG register.

LoongArch: Add system call support
Add system call support and related uaccess.h for LoongArch. Q: Why keep _ARCH_WANT_SYS_CLONE definition while there is clone3: A: The latest glibc release has some basic support for clone3 but it is not complete. E.g., pthread_create() and spawni() have converted to use clone3 but fork() will still use clone. Moreover, some seccomp related applications can still not work perfectly with clone3. E.g., Chromium sandbox cannot work at all and there is no solution for it, which is more terrible than the fork() story [1].

LoongArch: Add boot and setup routines
Add basic boot, setup and reset routines for LoongArch. Now, LoongArch machines use UEFI-based firmware. The firmware passes configuration information to the kernel via ACPI and DMI/SMBIOS. Currently an existing interface between the kernel and the bootloader is implemented. Kernel gets 2 values from the bootloader, passed in registers a0 and a1; a0 is an "EFI boot flag" distinguishing UEFI and non-UEFI firmware, while a1 is a pointer to an FDT with systable, memmap, cmdline and initrd information. The standard UEFI boot protocol (EFISTUB) will be added later.
