NAK: [Trusty][SRU][PATCH 0/2] LP#1660519 -- Windows guest got 0x5c BSOD when rebooting

[Brad Figg]

Seyeong,

These patches are missing:

1. A buglink which poins at the Launchpad bug that they are supposedly
   fixing.

2. Your SOB.

3. Either a cherry-pick or backport line that tells us where these patches
   came from.

These are required for all SRU patches.

Thanks,
Brad
