The MPC8349 PIBs system has a expansion board with 6 PCI slots.  We needed
to update the IDSEL interrupt mapping for it to work properly.  However,
only PCI1 is supported as the first revision of this expansion board
doesn't function properly for PCI2.  For the time being we have zero'd out
the entries for the IDSELs related to PCI2.  When a functioning expansion
board exists we can fix the table.

The pages_high - pages_low and pages_low - pages_min deltas are the asynch
reclaim watermarks.  As such, the should be in the same ratios as any other
zone for highmem zones.  It is the pages_min - 0 delta which is the
PF_MEMALLOC reserve, and this is the region that isn't very useful for
highmem.

This patch ensures highmem systems have similar characteristics as non highmem
ones with the same amount of memory, and also that highmem zones get similar
reclaim pressures to other zones.

The address based work estimate for unmapping (for lockbreak) is and always
was horribly inefficient for sparse mappings.  The problem is most simply
explained with an example:

If we find a pgd is clear, we still have to call into unmap_page_range
PGDIR_SIZE / ZAP_BLOCK_SIZE times, each time checking the clear pgd, in
order to progress the working address to the next pgd.

The fundamental way to solve the problem is to keep track of the end
address we've processed and pass it back to the higher layers.

From: Nick Piggin <npiggin@suse.de>

  Modification to completely get away from address based work estimate
  and instead use an abstract count, with a very small cost for empty
  entries as opposed to present pages.

  On 2.6.14-git2, ppc64, and CONFIG_PREEMPT=y, mapping and unmapping 1TB
  of virtual address space takes 1.69s; with the following patch applied,
  this operation can be done 1000 times in less than 0.01s

From: Andrew Morton <akpm@osdl.org>

The file_lock spinlock sits close to mostly read fields of 'struct
files_struct'

In SMP (and NUMA) environments, each time a thread wants to open or close
a file, it has to acquire the spinlock, thus invalidating the cache line
containing this spinlock on other CPUS.  So other threads doing
read()/write()/...  calls that use RCU to access the file table are going
to ask further memory (possibly NUMA) transactions to read again this
memory line.

Move the spinlock to another cache line, so that concurrent threads can
share the cache line containing 'count' and 'fdt' fields.

It's worth up to 9% on a microbenchmark using a 4-thread 2-package x86
machine.  See

 The patch
 http://linux.bkbits.net:8080/linux-2.6/diffs/fs/locks.c@1.70??nav=index.html
 introduced a pretty nasty memory leak in the lease code. When freeing
 the lease, the code in locks_delete_lock() will correctly clean up
 the fasync queue, but when we return to fcntl_setlease(), the freed
 fasync entry will be reinstated.

 This patch ensures that we skip the call to fasync_helper() when we're
 freeing up the lease.
