Linux v5.3-13236-g97f9a3c4eee5

This is a first pass at getting the secureboot patches working with the
upstream lockdown patches that got merged. The final patch from our
lockdown set is the sysrq patch which also needs work. For the present
it is not applied.

-Date: Thu,  5 Sep 2019 20:24:12 +0100

-We have a production-level laptop (Lenovo Yoga C630) which is exhibiting
-a rather horrific bug.  When I2C HID devices are being scanned for at
-boot-time the QCom Geni based I2C (Serial Engine) attempts to use DMA.
-When it does, the laptop reboots and the user never sees the OS.
-
-Attempts are being made to debug the reason for the spontaneous reboot.
-No luck so far, hence the requirement for this hot-fix.  This workaround
-will be removed once we have a viable fix.
