In order for the RCU to work, the file table array, sets and their sizes must
be updated atomically.  Instead of ensuring this through too many memory
barriers, we put the arrays and their sizes in a separate structure.  This
patch takes the first step of putting the file table elements in a separate
structure fdtable that is embedded withing files_struct.  It also changes all
the users to refer to the file table using files_fdtable() macro.  Subsequent
applciation of RCU becomes easier after this.

First of a number of files_lock scaability patches.

 Here are the x86 numbers -

 tiobench on a 4(8)-way (HT) P4 system on ramdisk :

                                         (lockfree)
 Test            2.6.10-vanilla  Stdev   2.6.10-fd       Stdev
 -------------------------------------------------------------
 Seqread         1400.8          11.52   1465.4          34.27
 Randread        1594            8.86    2397.2          29.21
 Seqwrite        242.72          3.47    238.46          6.53
 Randwrite       445.74          9.15    446.4           9.75

 The performance improvement is very significant.
 We are getting killed by the cacheline bouncing of the files_struct
 lock here. Writes on ramdisk (ext2) seems to vary just too
 much to get any meaningful number.

 Also, With Tridge's thread_perf test on a 4(8)-way (HT) P4 xeon system :

 2.6.12-rc5-vanilla :

 Running test 'readwrite' with 8 tasks
 Threads     0.34 +/- 0.01 seconds
 Processes   0.16 +/- 0.00 seconds

 2.6.12-rc5-fd :

 Running test 'readwrite' with 8 tasks
 Threads     0.17 +/- 0.02 seconds
 Processes   0.17 +/- 0.02 seconds

 I repeated the measurements on ramfs (as opposed to ext2 on ramdisk in
 the earlier measurement) and I got more consistent results from tiobench :

 Randwrite       1189.6           4.04   1275.2          32.96

 Also running Tridge's thread_perf test on ppc64 :

 2.6.12-rc5-vanilla
 --------------------
 Running test 'readwrite' with 4 tasks
 Threads     0.20 +/- 0.02 seconds
 Processes   0.16 +/- 0.01 seconds

 2.6.12-rc5-fd
 --------------------
 Running test 'readwrite' with 4 tasks
 Threads     0.18 +/- 0.04 seconds
 Processes   0.16 +/- 0.01 seconds

 The benefits are huge (upto ~60%) in some cases on x86 primarily
 due to the atomic operations during acquisition of ->file_lock
 and cache line bouncing in fast path. ppc64 benefits are modest
 due to LL/SC based locking, but still statistically significant.

The NUMA API change that introduced kmalloc_node was accepted for
2.6.12-rc3.  Now it is possible to do slab allocations on a node to
localize memory structures.  This API was used by the pageset localization
patch and the block layer localization patch now in mm.  The existing
kmalloc_node is slow since it simply searches through all pages of the slab
to find a page that is on the node requested.  The two patches do a one
time allocation of slab structures at initialization and therefore the
speed of kmalloc node does not matter.

This patch allows kmalloc_node to be as fast as kmalloc by introducing node
specific page lists for partial, free and full slabs.  Slab allocation
improves in a NUMA system so that we are seeing a performance gain in AIM7
of about 5% with this patch alone.

More NUMA localizations are possible if kmalloc_node operates in an fast
way like kmalloc.

Test run on a 32p systems with 32G Ram.

These are measurement taken directly after boot and show a greater
improvement than 5%.  However, the performance improvements become less
over time if the AIM7 runs are repeated and settle down at around 5%.

Add a devname parameter to the pcmcia_device structure, fills it with

extend cb_writel(), exca_writeb(), exca_writel() to do a read[lb]() after
the write[lb]() to avoid possible problem with PCI write posting.

multifunction cards need to have the same irq assigned to both functions.
the code tries that but fails because ret is still set to CS_IN_USE which
results in the function having the CB irq assigned.  yenta_set_socket then
just changes the irq routing to use the PCI interrupt but the first
functions irq handler is registered on an ISA interrupt.  boom.

- thread_done should only be completed when the wait_queue is installed.

- all wake up conditions should be checked before schedule()

this fixes a hang of rmmod in the sequence modprobe yenta_socket; rmmod
yenta_socket as reported by Andreas Steinmetz.  w/o this rmmod yenta_socket
can hang on wait_for_completion() in pcmcia_unregister_socket()

Share code between setup-bus.c and yenta_socket.c: use the write-out code of
resources to the bridge also in yenta_socket.c, as it provides useful debug
output.  In addition, it fixes the bug that the CPU-centric resource view
might need to be transferred to the PCI-centric view: setup-bus.c does that,
while yenta-socket.c did not.
