#     powerpc/powermac: Use early_* IO variants in via_calibrate_decr()
#     
#     On a powermac platform, via the call path:
#     
#       start_kernel()
#         time_init()
#           ppc_md.calibrate_decr() (pmac_calibrate_decr)
#             via_calibrate_decr()
#     
#     ioremap() and iounmap() are called. The unmap can enable interrupts
#     unexpectedly (cond_resched() in vunmap_pmd_range()), which causes a
#     warning later in the boot sequence in start_kernel().
#     
#     Use the early_* variants of these IO functions to prevent this.
#     
#     The issue is pre-existing, but is surfaced by commit 721255b9826b
#     ("genirq: Use a maple tree for interrupt descriptor management").
