-Subject: ARM: Fix FIQ code on VIVT CPUs
-
-Aaro Koskinen reports the following oops:
-Installing fiq handler from c001b110, length 0x164
-Unable to handle kernel paging request at virtual address ffff1224
-pgd = c0004000
-[ffff1224] *pgd=00000000, *pte=11fff0cb, *ppte=11fff00a
-...
-[<c0013154>] (set_fiq_handler+0x0/0x6c) from [<c0365d38>] (ams_delta_init_fiq+0xa8/0x160)
- r6:00000164 r5:c001b110 r4:00000000 r3:fefecb4c
-[<c0365c90>] (ams_delta_init_fiq+0x0/0x160) from [<c0365b14>] (ams_delta_init+0xd4/0x114)
- r6:00000000 r5:fffece10 r4:c037a9e0

-
-This is because the vectors page is now write-protected, and to change
-code in there we must write to its original alias. Make that change,
-and adjust the cache flushing such that the code will become visible
-to the instruction stream on VIVT CPUs.
