However, a few instructions remained 32 bits only. By using the accurate MACRO, it is now possible to deal with memory address beyond 32 bits. As a side effect, when using 64bits processor, it also divides the loop number needed to clear the BSS by 2.

This memory used to run kernel. This mean, one should have memory installed in this area in order for Linux to work. Kconfig CONFIG_USE_XKPHYS introduced; it adds support for kernel to use virtual addresses from the XKPHYS segment for both cached and uncached access. XKPHYS allows to access 2^48 bytes of memory, thus allowing kernel to work with any memory configuration. MIPS CPU sets KX bit in the CP0 status register at reset if RESET_BASE_MODE (BIT 1) set in the GCR_CL_RESET_BASE. Reset vector should fit into 32-bit. If reset vector put outside of KSEG1, BIT(1) should be set in this value.
