Linux 4.19.290

[Greg Kroah-Hartman]

-----------------
Note, PLEASE TEST this kernel if you are on the 4.19.y tree before using
it in a real workload.  This was a quick release due to the obvious
security fixes in it, and as such, it has not had very much testing "in
the wild".  Please let us know of any problems seen.  Also note that the
user/kernel api for the new security mitigations might be changing over
time, so do not get used to them being fixed in stone just yet.
-----------------

I'm announcing the release of the 4.19.290 kernel.

All users of the 4.19 kernel series must upgrade.

The updated 4.19.y git tree can be found at:
	git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.19.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
