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
