This new config parameter limits the space used for "Lock debugging:You forgot to Cc Dave, and since you're touching sparc I need an Ack
prove locking correctness" by about 4MB. The current sparc systems
the limitation of 32MB size for kernel size including .text, .data and
.bss sections. With PROVE_LOCKING feature, the kernel size could grow
beyond this limit and causing system boot-up issues. With this option,
kernel limits the size of the entries of lock_chains, stack_trace
so that kernel fits in required size limit. This is not visible to
and only used for sparc.
