#     powerpc/32s: Fix build failure with CONFIG_PPC_KUAP_DEBUG
#     
#     gpr2 is not a parametre of kuap_check(), it doesn't exist.
#     
#     Use gpr instead.

WARNING: modpost: vmlinux.o(.text.unlikely+0x2b0): Section mismatch in reference from the function early_init_mmu() to the function .init.text:radix__early_init_mmu()
The function early_init_mmu() references
the function __init radix__early_init_mmu().
This is often because early_init_mmu lacks a __init 
annotation or the annotation of radix__early_init_mmu is wrong.
