Bug#905461: ia64: architecture is incompatible with CONFIG_SCHED_STACK_END_CHECK

[Jason Duerstock <jason.duerstock@gmail.com>]

Source: linux
Severity: normal

On ia64, enabling the CONFIG_SCHED_STACK_END_CHECK kernel option renders the kernel unbootable.
The "stack end" magic number that is set to enable this feature is overwritten by the ia64 processor backing store.
Is it possible to override a global kernel setting in the arch config file?

Thanks,

Jason
