The Linux kernel configuration item CONFIG_DEBUG_PER_CPU_MAPS
has multiple definitions:
lib/Kconfig.debug
The configuration item CONFIG_DEBUG_PER_CPU_MAPS:
( CONFIG_DEBUG_KERNEL ) && ( CONFIG_SMP )
Say Y to verify that the per_cpu map being accessed has been set up. This adds a fair amount of code to kernel memory and decreases performance.
Say N if unsure.
arch/x86/Kconfig.debug
The configuration item CONFIG_DEBUG_PER_CPU_MAPS:
( CONFIG_DEBUG_KERNEL ) && ( CONFIG_SMP )
Say Y to verify that the per_cpu map being accessed has been setup. Adds a fair amount of code to kernel memory and decreases performance.
Say N if unsure.
arch/powerpc/Kconfig.debug
The configuration item CONFIG_DEBUG_PER_CPU_MAPS:
( CONFIG_DEBUG_KERNEL ) && ( CONFIG_SMP )
