hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8JVJ3 CVE: NA ------------------------------------------------------------------------- No one currently uses IPL32, close it to simplify the code logic of TASK_SIZE_MAX, thereby improving benchmark performance. For example, all test items of libMicro can be improved by 4.89% on average. Since commit 7f6675f0e994 ("arm64: rename COMPAT to AARCH32_EL0"), CONFIG_COMPAT has been renamed to CONFIG_AARCH32_EL0, so open CONFIG_AARCH32_EL0 as what CONFIG_COMPAT used to be. And CONFIG_BUILTIN_RETURN_ADDRESS_STRIPS_PAC depends on the GCC or CLANG version, so it depends on the compilation environment.
