Cover letter [RFC PATCH v1 0/3] Enable CONFIG_VMAP_STACK on the 8xx
The purpose of this serie is to enable CONFIG_VMAP_STACK on the 8xx.
I'm sending it now to get early feedback if any.
For the time being, there is no proper handling of stack overflow.
This serie applies on the top of the serie "powerpc: Switch to CONFIG_THREAD_INFO_IN_TASK"
