    SubjectRe: [PATCH 1/3] Separate IRQ-stacks from 4K-stacks option

    You only have 4K safe to use in all current configurations. Its a case
    of simply fixing the sloppy code (and or pushing up compiler versions
    where the compiler is the offender).

    We've seen no evidence of this and assuming apps could use 4K safely the
    interrupt "stack" was about 2.5K before. Limiting it either by size or
    by depth is not a big problem at all.
