These two backports fix bugs in the MIPS uaccess functions for MIPS Enhanced Virtual Addressing (EVA), which were added in v3.15.
The upstream commits don't work directly when applied to kernels older than v4.2 where the eva_kernel_access() function was introduced, so we instead use segment_eq() directly, along with config_enabled(CONFIG_EVA) where necessary to avoid module symbol errors.
