#     powerpc/64s/kuap: Restore AMR in fast_interrupt_return
#     
#     Interrupts that use fast_interrupt_return actually do lock AMR, but
#     they have been ones which tend to come from userspace (or kernel bugs)
#     in radix mode. With kuap on hash, segment interrupts are taken in
#     kernel often, which quickly breaks due to the missing restore.

WARNING: modpost: vmlinux.o(.text.unlikely+0x3e0): 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.
