Upgrade kernel to 4.14.341-openela

This is a continuation of the 4.14 series by the Open Enterprise Linux
Alliance, ostensibly to the same maintenance standards as the now
discontinued kernel.org LTS.

This code is primarily offered as a Git repository, with gz tarballs
also available, but no xz versions. Switching back to a gzipped version
of the kernel source code would introduce too much srcfs growth, so we
use the last kernel.org tar.xz release (4.14.336), and apply OpenELA's
changes using a patch generated from the Git repository.

+Subject: [PATCH] x86/virt: Force GIF=1 prior to disabling SVM (for reboot
+ flows)
+
+commit 6a3236580b0b1accc3976345e723104f74f6f8e6 upstream.
+
+Set GIF=1 prior to disabling SVM to ensure that INIT is recognized if the
+kernel is disabling SVM in an emergency, e.g. if the kernel is about to
+jump into a crash kernel or may reboot without doing a full CPU RESET.
+If GIF is left cleared, the new kernel (or firmware) will be unabled to
+awaken APs.  Eat faults on STGI (due to EFER.SVME=0) as it's possible
+that SVM could be disabled via NMI shootdown between reading EFER.SVME
+and executing STGI.
