ata_get_mode_mask() uses bits 3 and 4 in the pio_mask to represent PIO
modes 3 and 4. The value read from the drive, which reports support
for PIO3 and PIO4 in bits 0 and 1, is shifted left by 3 bits and OR'd
with 0x7 (which then corresponds to PIO 2-0 in libata). Thus, the
drivers below need adjustments to comply with the way pio_mask is
used. I changed the masks from the commented values to all support
PIO4-0, since the spec mandates that PIO0-2 are supported and there's
no reason not to support PIO3 IMO.

Hi Jeff,
This is version 19 of the Wireless Extensions. It was supposed
to be the fallback of the WPA API changes, but people seem quite happy
about it (especially Jouni), so the patch is rather small.
The patch has been fully tested with 2.6.13 and various
wireless drivers, and is in its final version. Would you mind pushing
that into Linus's kernel so that the driver and the apps can take
advantage ot it ?
It includes :
o iwstat improvement (explicit dBm). This is the result of
long discussions with Dan Williams, the authors of
NetworkManager. Thanks to him for all the fruitful feedback.
o remove pointer from event stream. I was not totally sure if
this pointer was 32-64 bits clean, so I'd rather remove it and be at
peace with it.
o remove linux header from wireless.h. This has long been
requested by people writting user space apps, now it's done, and it
was not even painful.
o final deprecation of spy_offset. You did not like it, it's
now gone for good.
o Start deprecating dev->get_wireless_stats -> debloat netdev
o Add "check" version of event macros for ieee802.11
stack. Jiri Benc doesn't like the current macros, we aim to please ;-)
All those changes, except the last one, have been bit-roting on
my web pages for a while...
Patches for most kernel drivers will follow. Patches for the
Orinoco and the HostAP drivers have been sent to their respective
maintainers.
Have fun...

This patch adds a driver for a new 1000 Mbit ethernet NIC. It is
integrated on the south bridge that is used for our Cell Blades.
The code gets the MAC address from the Open Firmware device tree, so it
won't compile on platforms other than ppc64.
This is the first public release, so I don't expect the first version to
get merged, but I'd aim for integration within the 2.6.13 time frame.

Hi,
This patch contains the following hardware related fixes and other
miscellaneous bug fixes.
1. Updated the definition of single and double-bit ECC errors
2. Earlier we were allocating Transmit descriptors equal to
MAX_SKB_FRAGS. This was causing a boundary condition failure.
Need to allocate MAX_SKB_FRAGS+1 descriptors.
3. On some platforms(like PPC), pci_alloc_consistent() can return
a zero DMA address. Since the NIC cannot handle zero-addresses,
a workaround has been provided. Basically, we don't use such
that page. We reallocate.
4. If list_info allocation failed during driver load, check for
it during driver exit and return instead of trying to dereference
NULL pointer.
5. Increase the debug level of few non-critical debug messages.
6. Reset the card on critical ECC double errors only in case of
XframeI since XframeII can recover from such errors.
7. Print copyright message on driver load.
8. Bumped up the driver version no. to 2.0.8.1

scsi_io_completion() can be a bit noisy about certain conditions.
Previously this wasn't a problem for internally generated commands,
since they never hit it. However, since we do all SCSI commands via
bios, now they do. user CD testers like magicdev are now getting not
ready messages every time they touch the CD to see if there's anything
in it.
Fix this by making all scsi_execute commands REQ_QUIET and making
scsi_finish_io() not say anything for REQ_QUIET.

This patch adds a delay tailored for USB flash devices that are slow to
initialize their firmware. The symptom is a repeated Unit Attention with
ASC=0x28 (Not Ready to Ready transition). The patch will wait for up to 5
seconds for such devices to become ready. Normal devices won't send the
repeated Unit Attention sense key and hence won't trigger the patch.
This fixes a problem with James Roberts-Thomson's USB device, and I've
seen several reports of other devices exhibiting the same symptoms --
presumably they will be helped as well.

The problem lies in the way the error handler uses TEST UNIT READY to
tell whether error recovery has succeeded. The scsi_eh_tur function
gives up after one round of retrying; after that it decides that more
error recovery is needed.
However TUR is liable to report sense data indicating a retry is needed
when in fact error recovery has succeeded. A typical example might be
SK=2, ASC=4, ASCQ=1 (Logical unit in process of becoming ready). The mere
fact that we were able to get a sensible reply to the TUR should indicate
that the device is working well enough to stop error recovery.
I ran across a case back in January where this happened. A CD-ROM drive
timed out the INQUIRY command, and a device reset fixed the blockage.
But then the drive kept responding with 2/4/1 -- because it was spinning
up I suppose -- until the error handler gave up and placed it offline.
If the initial INQUIRY had received the 2/4/1 instead, everything would
have worked okay. It doesn't seem reasonable for things to fail just
because the error handler had started running.

When the NAT module is loaded when connections are already confirmed
it must not change their tuples anymore. This is especially important
with CONFIG_NETFILTER_DEBUG, the netfilter listhelp functions will
refuse to remove an entry from a list when it can not be found on
the list, so when a changed tuple hashes to a new bucket the entry
is kept in the list until and after the conntrack is freed.
Allocate the exact conntrack tuple for NAT for already confirmed

And unfortunatly l_linger is defined as a 'signed int' in
include/linux/socket.h:
struct linger {
int l_onoff; /* Linger active */
int l_linger; /* How long to linger for */
};
I dont know if it's safe to change l_linger to 'unsigned int' in the
include file (It might be defined as int in ABI specs)
