These patches limit the static allocations for lockdep data structures used for debugging locking correctness. This is required for sparc as it requires .text, .data and .bss to fit in required 32MB limit for the kernel. Right now, with PROVE_LOCKING enabled we could go over this limit and cause system boot-up problems. These patches limit the static allocations so that everything fits in current required space limit. This is only visible for sparc. patch 1 : Adds new config parameter CONFIG_PROVE_LOCKING_SMALL Patch 2 : Adjusts the sizes based on the new config parameter v1-> v2: As suggested by Peter Zijlstra, keeping the default as is. Introduced new config variable CONFIG_PROVE_LOCKING_SMALL to handle sparc specific case. v0: Initial revision. Babu Moger (2): config: Add new CONFIG_PROVE_LOCKING_SMALL lockdep: Keep the static allocations small for PROVE_LOCKING_SMALL kernel/locking/lockdep_internals.h | 13 ++++++++++--- lib/Kconfig.debug | 17 +++++++++++++++++ 2 files changed, 27 insertions(+), 3 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
