Linux 5.3 released

Linux 5.3 has been released.

This release includes support for AMD Navi GPUs; support for the umwait x86 instructions that let processes wait for short amounts of time without spinning loops; a ‘utilization clamping’ mechanism that is used to boost interactivity on power-asymmetric CPUs used in phones; a new pidfd_open(2) system call that completes the work done to let users deal with the PID reuse problem; 16 millions of new IPv4 addresses in the range are made available; support for Zhaoxin x86 CPUs; support Intel Speed Select for easier power selection in Xeon servers; and support for the lightweight hypervisor ACRN, built for embedded IoT devices.

As always, many other new drivers and improvements can be found in the changelog.
