5ef66935c1 prom_free_prom_memory() returns unsigned long 
Some boards declare prom_free_prom_memory as a void function but the
    caller free_initmem() expects a return value.
    
    Fix those up and return 0 instead, just like everyone else does.

e5adb8770e Hack to resolve longstanding prefetch issue 
Prefetching may be fatal on some systems if we're prefetching beyond the
end of memory on some systems.  It's also a seriously bad idea on non
dma-coherent systems.

cb4262481f pci-expmem-hack 
CFE 1.2.5 and earlier fails to turn on the ExpMemEn bit in the
PCIFeatureControl register, which means that DMA does not work
beyond physical address 01_0000_0000, ergo to DRAM beyond 1GB.
    
With ExpMemEn turned on, 01_0000_0000-0f_ffff_ffff is mapped,
so DMA works for up to 61 GB of DRAM.
    
Will be fixed in CFE 1.2.6 (yet to be released).

1d40cfcd34 Avoid SMP cacheflushes. This is a minor optimization of startup but 
will also avoid smp_call_function from doing stupid things when called
from a CPU that is not yet marked online.

569f75bd02 Use an irq_enable_hazard hazard barrier in unmask_mips_irq. This 
hasn't been an actual bug, so it's more a change to be 100% compliant
with the requirements of the architecture spec.  Similar fix to
mask_mips_irq where there was a slightly less theoretical chance of
getting hit.
