From e6b5f1be7afe1657c40c08082c562b1a036a54c1 Mon Sep 17 00:00:00 2001 From: Babu Moger Date: Wed, 2 Nov 2016 09:36:32 -0700 Subject: config: Adding the new config parameter CONFIG_PROVE_LOCKING_SMALL for sparc This new config parameter limits the space used for "Lock debugging: prove locking correctness" by about 4MB. The current sparc systems have 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 etc., so that kernel fits in required size limit. This is not visible to user and only used for sparc.
