The SMU is the "system controller" chip used by Apple recent G5 machines
including the iMac G5.  It drives things like fans, i2c busses, real time
clock, etc...

The current kernel contains a very crude driver that doesn't do much more
than reading the real time clock synchronously.  This is a completely
rewritten driver that provides interrupt based command queuing, a userland
interface, and an i2c/smbus driver for accessing the devices hanging off
the SMU i2c busses like temperature sensors.  This driver is a basic block
for upcoming work on thermal control for those machines, among others.

The recent iommu fix broke booting on some POWER4 and POWER5 LPAR boxes.

It looks like we have been calling the non LPAR iommu_dev_setup on LPAR
machines for a while. The recent iommu fix caused that code path to
fail.

It looks like we just need to hook up the devices iommu_table to the
parents one, so do that instead of calling iommu_dev_setup_pSeries and
crossing the streams.

The numa slab allocator may allocate pages from foreign nodes onto the
lists for a particular node if a node runs out of memory.  Inspecting the
slab->nodeid field will not reflect that the page is now in use for the
slabs of another node.

This patch fixes that issue by adding a node field to free_block so that
the caller can indicate which node currently uses a slab.

Also removes the check for the current node from kmalloc_cache_node since
the process may shift later to another node which may lead to an allocation
on another node than intended.

The address passed to io_remap_pfn_range() in hpet_mmap() does not need to
be converted using __pa(): it is already a physical address.  This bug was
found and the patch suggested by Clay Harris.

I introduced this particular bug when making io_remap_pfn_range changes a
few months ago.  In fact mmap()ing /dev/hpet has *never* previously worked:
before my changes __pa() was being executed on an ioremap()ed virtual
address, which is also invalid.

If error occurs while in v9fs_get_sb after it calles sget, the dentry object
of the root and its inode may be freed twice -- once while handling the error
in v9fs_get_sb, and second time when v9fs_get_sb calles deactivate_super
(which in turn calls v9fs_kill_super)

The patch removes the unnecessary code that frees the root dentry and its
inode.

v9fs_vfs_readlink allocates space for the link using __getname and

When a new session is created it uses a template object of the specified
transport type to instantiate its own copy.  The code for the making a copy of
the template object was lost, and the object itself is attached to the v9fs
session.  This leads to many sessions using the same transport instead of
having their own copy.

The patch puts back the code that makes a copy of the template object.

buf_check_size function checks if the conv buffer has enough space for the
performed operation, but it doesn't return the result back to the calling
function, only logs an error in the log.

The report-back-error functionality was lost when buf_check_size was
converted from macro to inline function. The return in the macro used to
exit from the functions that include it, after the conversion it just exits
from the inline function itself.

The patch makes buf_check_size to return flag and all functions that use
it check if they should perform the operation, or exit.

In the lead up to 2.6.13 I fixed a large number of reboot problems by
making the calling conventions consistent.  Despite checking and double
checking my work it appears I missed an obvious one.

The S4 suspend code for PM_DISK_PLATFORM was also calling device_shutdown
without setting system_state, and was not calling the appropriate
reboot_notifier.

This patch fixes the bug by replacing the call of device_suspend with
kernel_poweroff_prepare.

Various forms of this failure have been fixed and tracked for a while.

Addresses some small bugs in the pegasus ethernet-over-USB driver.
Specifically, malformed long packets from the adapter could cause a kernel
panic; the interrupt interval calculation was inappropriate for high-speed
devices; the return code from read_mii_word was tested incorrectly; and
failure to unlink outstanding URBs before freeing them could lead to kernel
panics when unloading the driver.

Three minor sl811-hcd fixes:

 - Elminate memory leak on one (rare) disable/shutdown path.

 - For periodic transfers that don't need to be scheduled, update
   urb->start_frame to represent the transfer phase correctly.

 - Report the (single) port as removable, by default.

Since no drivers yet use start_frame or that part of the hub descriptor,
only that leak is likely to ever matter.

I'm using a 2 port USB RS232 dongle to connect to a serial-IR cradle for
a bar code reader). Detecting the baudrate of the serial-IR involves
keeping DTR low while changing baudrate.

This works using normal 16550A serial ports as well as the FTDI driver
version 1.4.0 (Linux 2.6.8) but stopped working with the change to
"ensure RTS and DTR are raised when changing baudrate" introduced in
version 1.4.1 (Linux 2.6.9).

The attached patch fixes this, so RTS and DTR is only raised when
changing baudrate iff the previous baudrate was B0.
