I was not happy when my patch disappeared. Luckily I had exported it a
little while earlier.

This error may have messed up my state and I didn't detect it until
later. 0008-drivers-net-Add-support-for-Freescale-MPC5200-SoC-i.patch
is the patch that went missing.

To: Git Mailing List <git@xxxxxxxxxxxxxxx>, catalin.marinas@xxxxxxxxx


Using current git source for Stg

Patch 008 was hidden and I used unhide to bring it back. But the
hide/unhide process moved it to the top of the stack. I need to sink
it back down to where it came from. Shouldn't hide/unhide preserve the
patch position in the stack?
