Greg, Sorry, if I'm missing something, but I see 3 patches for hpwdt queued up for 4.4: queue-4.4/watchdog-hpwdt-fix-unused-variable-warning.patch queue-4.4/watchdog-hpwdt-smbios-check.patch queue-4.4/watchdog-hpwdt-check-source-of-nmi.patch Shouldn't there also be a 4.4 patch for commit 2b3d89b402b085b08498e896c65267a145bed486 watchdog: hpwdt: Remove legacy NMI sourcing. As there was for 4.15, 4.14, and 4.9? commit 2b3d89b40 is the Spectre related patch. thanks Jerry Hoemann On Fri, Mar 16, 2018 at 04:23:01PM +0100, Greg Kroah-Hartman wrote: > 4.4-stable review patch.
