Using PCIE advanced error recovery stuff creates more user problems than it's worth.
The AER stuff depends on MMCONFIG and in many configurations it just doesn't work.
Plus it doesn't add any real functionality to the driver. The sky2
driver handles its own errors fine as is.

Using the hardware window into PCI config space is more reliable
and smaller/faster than using the pci_config routines. It avoids issues
with MMCONFIG etc.

Bug cause is blast_dcache_range() in preemptible code [in
r4k_dma_cache_wback_inv()].
blast_dcache_range() is constructed via __BUILD_BLAST_CACHE_RANGE that
uses cpu_dcache_line_size(). It uses current_cpu_data that use
smp_processor_id() in turn. In case of CONFIG_DEBUG_PREEMPT
smp_processor_id emits BUG if we are executing with preemption
enabled.

The database performance group have found that half the cycles spent
in kmem_cache_free are spent in this one call to BUG_ON.  Moving it
into the CONFIG_SLAB_DEBUG-only function cache_free_debugcheck() is a
performance win of almost 0.5% on their particular benchmark.

The call was added as part of commit ddc2e812
with the comment that "overhead should be minimal".  It may have been
minimal at the time, but it isn't now.

[ Quoth Pekka Enberg: "I don't think the BUG_ON per se caused the
  performance regression but rather the virt_to_head_page() changes to
  virt_to_cache() that were added later." ]

I'm not sure why it was doing this, and I'm not sure I _want_ to know
