upgrade Linux Kernel

Linux Kernel 5.5 was announced two days ago. Linus Torvalds wrote on lkml.org:

“So this last week was pretty quiet, and while we had a late network update with some (mainly iwl wireless) network driver and netfilter module loading fixes, David didn’t think that warranted another -rc. And outside of that, it’s really been very quiet indeed – there’s a panfrost driver update too, but again it didn’t really seem to make sense to delay the final release by another week.

…”

Kernel 5.5 release highlights:

  • Support for the Broadcom BCM2711 SoC (Raspberry Pi 4).
  • New Logitech driver for G15 and G510 keyboard.
  • KVM support for IBM POWER secure guests/VMs.
