Linux 6.6.81

I'm announcing the release of the 6.6.81 kernel.

All users, EXCEPT i386 systems, of the 6.6 kernel series must upgrade.

Note, the i386 arch is currently broken, please wait for the next release before you upgrade.

The updated 6.6.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-6.6.y
and can be browsed at the normal kernel.org git web browser:
https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary

thanks,

greg k-h
