# As per target team, build is done as follows:
# Defconfig : build with default flags
# Slub      : defconfig  + CONFIG_SLUB_DEBUG := y +
#	      CONFIG_SLUB_DEBUG_ON := y + CONFIG_PAGE_POISONING := y
# Perf      : Using appropriate msmXXXX-perf_defconfig
#
# Shipment builds (user variants) should not have any debug feature
# enabled. This is identified using 'TARGET_BUILD_VARIANT'. Slub builds
# are identified using the CONFIG_SLUB_DEBUG_ON configuration. Since
# there is no other way to identify defconfig builds, QTI internal
# representation of perf builds (identified using the string 'perf'),
# is used to identify if the build is a slub or defconfig one. This
# way no critical debug feature will be enabled for perf and shipment
# builds. Other OEMs are also protected using the TARGET_BUILD_VARIANT
# config.
