* phylib: add mdiobus_{read,write}Lennert Buytenhek2008-10-091-8/+38
| | | | | | | | | Add mdiobus_{read,write} routines to allow direct reading/writing of registers on an mii bus without having to go through the PHY abstraction, and make phy_{read,write} use these primitives.

* phylib: give mdio buses a device tree presenceLennert Buytenhek2008-10-091-0/+8
| | | | | | | | | | Introduce the mdio_bus class, and give each 'struct mii_bus' its own 'struct device', so that mii_bus objects are represented in the device tree and can be found by querying the device tree.

| | | | | | | | | | This patch introduces mdiobus_alloc() and mdiobus_free(), and makes all mdio bus drivers use these functions to allocate their struct mii_bus'es dynamically.

* phylib: rename mii_bus::dev to mii_bus::parentLennert Buytenhek2008-10-091-1/+1
| | | | | | | | | | | | In preparation of giving mii_bus objects a device tree presence of their own, rename struct mii_bus's ->dev argument to ->parent, since having a 'struct device *dev' that points to our parent device conflicts with introducing a 'struct device dev' representing our own device.

| | | | | | | | | | | | | | | | | | | | | | Rework of SMTC support to make it work with the new clock event system, allowing "tickless" operation, and to make it compatible with the use of the "wait_irqoff" idle loop.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous patch db203d53d474aa068984e409d807628f5841da1b ("mm: tiny-shmem fix lock ordering: mmap_sem vs i_mutex") to fix the lock ordering in tiny-shmem breaks shared anonymous and IPC memory on NOMMU architectures because it was using the expanding truncate to signal ramfs to allocate a physically contiguous RAM backing the inode (otherwise it is unusable for "memory mapping" it to userspace). However do_truncate is what caused the lock ordering error, due to it taking i_mutex. In this case, we can actually just call ramfs directly to allocate memory for the mapping, rather than go via truncate.

* | | | sctp: shrink sctp_tsnmap some more by removing gabs arrayVlad Yasevich2008-10-081-11/+3Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The gabs array in the sctp_tsnmap structure is only used in one place, sctp_make_sack(). As such, carrying the array around in the sctp_tsnmap and thus directly in the sctp_association is rather pointless since most of the time it's just taking up space. Now, let sctp_make_sack create and populate it and then throw it away when it's done. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: David S. Miller <davem@davemloft.net>

What we really need is at most 4K worth of bits so the biggest map we would have is 512 bytes. Also, the map is only really usefull when we have gaps to store and report. As such, starting with minimal map of say 32 TSNs (bits) should be enough for normal low-loss operations. We can grow the map by some multiple of 32 along with some extra room any time we receive the TSN which would put us outside of the map boundry. As we close gaps, we can shift the map to rebase it on the latest TSN we've seen. This saves 4088 bytes per association just in the map alone along savings from the now unnecessary structure members.

Moreover, sysctl_local_port_range[] was close to unrelated variables, highly modified, leading to cache misses. Moving these two variables in a structure can help data locality and moving this structure to read_mostly section helps sharing of this data among cpus. Cleanup of extern declarations (moved in include file where they belong), and use of inet_get_local_port_range() accessor instead of direct access to ports values.

The "offset" parameter for example has been renamed to "fragoff" (there are so many different offsets already) and "protoff" to "thoff" (there is more than just one protocol here, so clarify).
