SubjectRe: [PATCH] remove LOCK_SECTION from x86_64 spin_lock asm

this might work for x64, but even there, are you sure it works even with
CONFIG_PREEMPT enabled (there the spinlocks are more complex)? It sure
wont work on x86 so i think we need a generic 'soft PC' solution.

the alternative would be to unwind the stack - quite some task on some
platforms ...
