Looks ok to me except several leftovers:

$ git grep CONFIG_MMU arch/microblaze/
arch/microblaze/kernel/hw_exception_handler.S: * STACK FRAME STRUCTURE (for CONFIG_MMU=n)

$ git grep -E 'MICROBLAZE_(64|16)K_PAGES'
arch/microblaze/include/asm/page.h:#if defined(CONFIG_MICROBLAZE_64K_PAGES)
arch/microblaze/include/asm/page.h:#elif defined(CONFIG_MICROBLAZE_16K_PAGES)
arch/microblaze/kernel/hw_exception_handler.S:#ifdef CONFIG_MICROBLAZE_64K_PAGES
arch/microblaze/kernel/hw_exception_handler.S:#elif CONFIG_MICROBLAZE_16K_PAGES
drivers/net/Kconfig:                 IA64_PAGE_SIZE_64KB || MICROBLAZE_64K_PAGES || \
