Kernel: Unicore32 and IO_uring in Linux

Linux 5.9 Dropping The Unicore 32-bit RISC Architecture
It's arguably long overdue but with the just-opened Linux 5.9 kernel cycle the Unicore32 CPU architecture is being removed.
Unicore is a 32-bit RISC architecture developed at China's Peking University. Unicore is an ARM-like architecture. But with Unicore not being too popular and this code not seeing any maintenance for the mainline kernel paired with no upstream compiler support, it's time to gut the code out of the kernel.

IO_uring Has Many Improvements Set To Go Into Linux 5.9
Facebook's Jens Axboe who oversees the Linux storage/block code and leads the IO_uring efforts summed up the changes for Linux 5.9 as "hardening the code and/or making it easier to read and fixing [bits]." There is though a big change and that is proper async buffered reads support. That work was previously covered but didn't end up getting pulled into Linux 5.8 due to a branching difference but is now ready to go with Linux 5.9. The async buffered reads support for IO_uring has some nice performance advantages and lower CPU usage while also working its way off KThreads for the fast code path once the async buffered write support is in place.

Samsung, Red Hat to Work on Linux Drivers for Future Tech
The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world.
Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility.
