Re: [PATCH 0/2] xtensa queue 2013/10/15 for 3.12

[Chris Zankel <chris@zankel.net>]

Hi Max,

Thanks for the patches. Is my assumption correct that this fixes memory
faults while in double exception? And, instead of panic-ing, it works
now but registers are likely wrong with ptrace?

Also, should that go in for 3.12 (rc6?) or only in 3.13?

Thanks,
-Chris
