I started arm linux kernel hacking.
I can't understand 554 line.
I think that 554 line is not necessary.
Because ISB instruction(556 line) makes synchronization between 553 and 557.
Please advice to me.
530 __armv7_mmu_cache_on:

.
553 mcr p15, 0, r0, c1, c0, 0 @ load control register
554 mrc p15, 0, r0, c1, c0, 0 @ and read it back
555 mov r0, #0
556 mcr p15, 0, r0, c7, c5, 4 @ ISB
557 mov pc, r12
Have a nice day.
MH Hong.
