[PATCH v4 12/14] mips: Replace arch specific way to determine 32bit task with generic version
From: Alexandre Ghiti
Date: Sun May 26 2019 - 10:04:38 EST
Mips uses TASK_IS_32BIT_ADDR to determine if a task is 32bit, but
this define is mips specific and other arches do not have it: instead,
use !IS_ENABLED(CONFIG_64BIT) || is_compat_task() condition.
