All of the LoongArch CPU architecture changes have been merged for the [1]Linux 6.16 kernel with the merge window set to wrap up later today.

LoongArch with Linux 6.16 brings support for enabling the multi-core scheduler support on these Chinese processors. The "SCHED_MC" Kconfig option can now be enabled for enjoying better multi-core scheduling performance.

LoongArch with this next version of the Linux kernel also brings support for MSEAL to seal the system mappings, Stackleak protector support, support for up to a theoretical 2048 CPU cores, and other adjustments:

1, Adjust the 'make install' operation;

2, Support SCHED_MC (Multi-core scheduler);

3, Enable ARCH_SUPPORTS_MSEAL_SYSTEM_MAPPINGS;

4, Enable HAVE_ARCH_STACKLEAK;

5, Increase max supported CPUs up to 2048;

6, Introduce the numa_memblks conversion;

7, Add PWM controller nodes in dts;

8, Some bug fixes and other small changes.

See [2]this pull request for more details on all of these changes in Linux 6.16.
