For cases where the rbtree is mainly used for sorting and min retrieval,
a nice speedup of the rbtree code is to maintain a cache of the leftmost

cfq-iosched: rework the whole round-robin list concept
Drawing on some inspiration from the CFS CPU scheduler design, overhaul
the pending cfq_queue concept list management. Currently CFQ uses a
doubly linked list per priority level for sorting and service uses.
Kill those lists and maintain an rbtree of cfq_queue's, sorted by when
to service them.
This unfortunately means that the ionice levels aren't as strong
anymore, will work on improving those later. We only scale the slice
time now, not the number of times we service. This means that latency
is better (for all priority levels), but that the distinction between
the highest and lower levels aren't as big.
The diffstat speaks for itself.

- Improve residual slice time accounting.
- Remove dead code: we no longer see async requests coming in on

that we can also remove the difference between cfq_cfqq_sync()

kill the on_dispatch array, just make it a counter.
- Allow a process to go into the current list, if it hasn't been
serviced in this scheduler tick yet.

in cfq_close_cooperator(), so we don't have to look it up twice.

ieee1394: eth1394: don't autoload by hotplug when ohci1394 starts
Until now, ieee1394 put an IP-over-1394 capability entry into each new
host's config ROM. As soon as the controller was initialized --- i.e.
right after modprobe ohci1394 --- this entry triggered a hotplug event
which typically caused auto-loading of eth1394.
This irritated or annoyed many users and distributors. Of course they
could blacklist eth1394, but then ieee1394 wrongly advertized IP-over-
1394 capability to the FireWire bus.
Therefore
- remove the offending kernel config option
IEEE1394_CONFIG_ROM_IP1394,
- let eth1394 add the ROM entry by itself, i.e. only after eth1394 was
loaded.
This fixes http://bugzilla.kernel.org/show_bug.cgi?id=7793 .
To emulate the behaviour of older kernels, simply add the following to
to /etc/modprobe.conf:
install ohci1394 /sbin/modprobe eth1394; \
/sbin/modprobe --ignore-install ohci1394
Note, autoloading of eth1394 when an _external_ IP-over-1394 capable
device is discovered is _not_ affected by this patch.

ieee1394: replace vmalloc by kmalloc in csr1212
The biggest chunk ever allocated by CSR1212_MALLOC is 1024 Bytes +
sizeof(struct csr1212_csr_rom_cache) big. Most of the time much
smaller data structures are allocated. Therefore vmalloc is a waste.
The one exception is csr1212_append_new_cache() which is called to
append a chunk of CSR1212_EXTENDED_ROM_SIZE + sizeof(struct
csr1212_csr_rom_cache) if the currently allocated ROM cache is too
small. CSR1212_EXTENDED_ROM_SIZE is generously defined as 256 kBytes.
In SVN commit 1220, Steve Kinneberg lowered this to 2 kBytes in the
config_rom_2.4 branch. This same commit also switched CSR1212_MALLOC
from kmalloc to vmalloc in the SVN trunk branch:

(It was actually 2 kB, not 8 kB.)
> - Fix hpsb_allocate_and_register_addrspace() to not allocate space
> on top of already allocated space.
> - Fix problems in csr1212.c filling ConfigROM images when extend

I am now setting CSR1212_EXTENDED_ROM_SIZE to 2 kB minus the overhead of
struct csr1212_csr_rom_cache. Note, this code path is not used by the
in-kernel drivers though. raw1394 could trigger it, but the respective
libraw1394 functions don't exist yet.
Furthermore, userspace programs can replace the entire local ROM via
raw1394. If kmalloc does not fulfill their needs --- well, tough luck.
I decree that nobody needs such huge extended ROMs. (Extended ROMs are
defined by IEEE 1212 clause 7.7.18. The spec does not impose
practically relevant restrictions on the size of extended ROM chunks.)
Another potentially demanding use of CSR1212_MALLOC is if external
FireWire devices come with Extended ROM entries. If they are too big
for kmalloc (or have been too big for vmalloc) we just fail to read
their ROM. This is quite unlikely though, to my knowledge.

ieee1394: sbp2: remove unnecessary alignments of struct members
The members "dma_addr_t command_orb_dma" and "dma_addr_t sge_dma" of
sbp2.h::sbp2_command_info do not have to be aligned themselves --- only
the memory which they point to has to be.
The member "struct sbp2_command_orb command_orb" has to be aligned on
4 bytes boundary which is guaranteed because it contains u32 members.
The member "struct sbp2_unrestricted_page_table scatter_gather_element",
i.e. the SBP-2 s/g table, has to be aligned on 8 bytes boundary
according to the SBP-2 spec. This is not a requirement for FireWire
controllers but could be expected by SBP-2 targets.
I see no need to align the members command_orb and
scatter_gather_element on CPU cacheline boundaries. It could have
performance benefits, but on the other hand sbp2 has a somewhat wasteful
allocation scheme which should be optimized first before further tweaks
like cacheline alignments. (E.g. don't always allocate SG_ALL s/g table
elements.)
Note, before as well as after the patch, the code relies on the
assumption that memory alignment in the virtual address space is
preserved in the physical address space after DMA mapping.

When network device's are renamed, the IPV6 snmp6 code
gets confused. It doesn't track name changes so it will OOPS
when network device's are removed.
The fix is trivial, just unregister/re-register in notify handler.

[SCTP]: Fix sctp_getsockopt_local_addrs_old() to use local storage.
sctp_getsockopt_local_addrs_old() in net/sctp/socket.c calls
copy_to_user() while the spinlock addr_lock is held. this should not
be done as copy_to_user() might sleep. the call to
sctp_copy_laddrs_to_user() while holding the lock is also problematic
as it calls copy_to_user()
