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.

This patch fixes a few problems with ub and cleans up a couple of things:
- Bump UB_MAX_REQ_SG, this allows to burn CDs
- Drop initialization of urb.transfer_flags,
now that URB_UNLINK_ASYNC is gone
- Add forgotten processing of stalls at GetMaxLUN
- Remove a few more P3-tagged printks whose time has come
- Correct comment about ZIP-100

This function expects an unsigned 32-bit type as its third argument:
static u32 pci_size(u32 base, u32 maxbase, u32 mask)
However, given these definitions:
#define PCI_BASE_ADDRESS_MEM_MASK (~0x0fUL)
#define PCI_ROM_ADDRESS_MASK (~0x7ffUL)
these two calls in drivers/pci/probe.c are problematic for architectures
for which a UL is not equivalent to a u32:
sz = pci_size(l, sz, PCI_BASE_ADDRESS_MEM_MASK);
sz = pci_size(l, sz, PCI_ROM_ADDRESS_MASK);
Hence the below compile warning when building for ARCH=ppc64:
drivers/pci/probe.c: In function `pci_read_bases':
/.../probe.c:168: warning: large integer implicitly truncated to unsigned type
/.../probe.c:218: warning: large integer implicitly truncated to unsigned type
Here is a simple fix.

The class symlinks in sysfs don't properly handle changing device names.
To demonstrate, rename your network device from eth0 to eth1. Your
pci (or usb, or whatever) device will still have a 'net:eth0' link,
except now it points to /sys/class/net/eth1.
The attached patch makes sure the class symlink name changes when
the class device name changes. It isn't 100% correct, it should be
using sysfs_rename_link. Unfortunately, sysfs_rename_link doesn't exist.

bus_rescan_devices_helper() does not hold the dev->sem when it checks for
!dev->driver(). device_attach() holds the sem, but calls again
device_bind_driver() even when dev->driver is set.
What happens is that a first device_attach() call (module insertion time)
is on the way binding the device to a driver. Another thread calls
bus_rescan_devices(). Now when bus_rescan_devices_helper() checks for
dev->driver it is still NULL 'cos the the prior device_attach() is not yet
finished. But as soon as the first one releases the dev->sem the second
device_attach() tries to rebind the already bound device again.
device_bind_driver() does this blindly which leads to a corrupt
driver->klist_devices list (the device links itself, the head points to the
device). Later a call to device_release_driver() sets dev->driver to NULL
and breaks the link it has to itself on knode_driver. Rmmoding the driver
later calls driver_detach() which leads to an endless loop 'cos the list
head in klist_devices still points to the device. And since dev->driver is
NULL it's stuck with the same device forever. Boom. And rmmod hangs.
Very easy to reproduce with new-style pcmcia and a 16bit card. Just loop
modprobe <pcmcia-modules> ;cardctl eject; rmmod <card driver, pcmcia
modules>.
Easiest fix is to check if the device is already bound to a driver in
device_bind_driver(). This avoids the double binding.

Because we don't access the PAGE_OFFSET linear mappings
any longer before we take over the trap table from the
firmware, we don't need to load dummy mappings there
into the TLB and we don't need the bootmap_base hack
any longer either.
While we are here, check for a larger than 8MB kernel
and halt the boot with an error message. We know that
doesn't work, so instead of failing mysteriously we
should let the user know exactly what's wrong.

Just allocate them physically starting from the end of
the kernel image. This incredibly simplifies our MM
bootstrap in that we don't need any mappings in the linear
PAGE_OFFSET area working in order to bootstrap ourselves and
take over the trap table from the firmware.
Many further simplifications are possible now, and this also
sets the stage for CONFIG_DEBUG_PAGEALLOC support.

So as to set the newly created sk_buff ->dev member with it, that way we stop
using dev_base->next, that is the wrong thing to do, as there may well be
several interfaces being used with LLC. This was not such a big problem after
all as most of the users of llc_alloc_frame were setting the correct dev, but
this way code is reduced.
This also fixes another bug in llc_station_ac_send_null_dsap_xid_c, that was
not setting the skb->dev field.

This was kind of ugly, and actually buggy. The bug was that
we didn't handle a machine with memory starting > 4GB. If
the 'prompmd' was allocated in physical memory > 4GB we'd
croak because the obp_iaddr_patch and obp_daddr_patch things
only supported a 32-bit physical address.
So fix this by just loading the appropriate values from two
variables in the kernel image, which is locked into the TLB
and thus accesses to them can't cause a recursive TLB miss.
