libata: add ATA_CBL_PATA_IGN

ATA_CBL_PATA_UNK indicates that the cable type can't be determined
from the host side and might be either 80c or 40c.  libata applies
drive or other generic limit in this case.  However, there are
controllers where both host and drive side detections are
misimplemented and the driver has to rely solely on private method -
peeking BIOS or ACPI configuration or using some other private
mechanism.

This patch adds ATA_CBL_PATA_IGN which tells libata to ignore the
cable type completely and just let the LLD determine the transfer mode
via host transfer mode masks and ->mode_filter().

Computing Group, where it is used for TCG features. This means that
an ATA8 TCG drive is going to trigger 32bit I/O on some systems which
will be funny.

Anyway we need to sort this out ready for ATA8 so:
- Reorder the ata.h header a bit so the ata_version function occurs early
  in it
- Make dword_io check the ATA version
- Add an ATA8 version checking TCG presence test

possible to disable TCG features at boot (and opt out of the trusted
model) as TCG intends because it relies on presence of a different
optional feature (DCS). Handle this in software by refusing the TCG
commands if libata.allow_tpm is not set. (We must make it possible
as some environments such as proprietary VDR devices will doubtless
want to use it to lock up content)

hwmon: (it87) request only Environment Controller ports

The IT8705F and related parts are Super I/O controllers that contain
many separate devices.

Some BIOSes describe IT8705F I/O port usage under a motherboard device
(PNP0C02) with overlapping regions, e.g., 0x290-0x29f and 0x290-0x294.

The it87 driver supports only the Environment Controller, which requires
only two ISA ports, but it used to request an eight-port range.  If that
range exceeds a range reported by the BIOS, as 0x290-0x297 would, the
request fails, and the it87 driver cannot claim the device.

This patch makes the it87 driver request only the two ports used for the
Environment Controller device.

[IPV6] ROUTE: Make sending algorithm more friendly with RFC 4861.

We omit (or delay) sending NSes for known-to-unreachable routers (in
NUD_FAILED state) according to RFC 4191 (Default Router Preferences
and More-Specific Routes).  But this is not fully compatible with RFC
4861 (Neighbor Discovery Protocol for IPv6), which does not remember
unreachability of neighbors.

So, let's avoid mixing sending algorithm of RFC 4191 and that of RFC
4861, and make the algorithm more friendly with RFC 4861 if RFC 4191
is disabled.

Issue was found by IPv6 Ready Logo Core Self_Test 1.5.0b2 (by TAHI
Project), and has been tracked down by Mitsuru Chinen

David S. Miller [Fri, 18 Jan 2008 12:21:39 +0000 (04:21 -0800)]
[NET]: Fix interrupt semaphore corruption in Intel drivers.

Several of the Intel ethernet drivers keep an atomic counter used to
manage when to actually hit the hardware with a disable or an enable.

The way the net_rx_work() breakout logic works during a pending
napi_disable() is that it simply unschedules the poll even if it
still has work.

This can potentially leave interrupts disabled, but that is OK
because all of the drivers are about to disable interrupts
anyways in all such code paths that do a napi_disable().

Unfortunately, this trips up the semaphore used here in the Intel
drivers.  If you hit this case, when you try to bring the interface
back up it won't enable interrupts.  A reload of the driver module
fixes it of course.

So what we do is make sure all the sequences now go:

napi_disable();
atomic_set(&adapter->irq_sem, 0);
*_irq_disable();

which makes sure the counter is always in the correct state.

Revert "sky2: remove check for PCI wakeup setting from BIOS"

This reverts commit 84cd2dfb04d23a961c5f537baa243fa54d0987ac.

Some BIOS's break if Wake On Lan is enabled, and the machine
can't boot. Better to have some user's have to call ethtool to
enable WOL than to break a single user's boot.

16 years agobonding: Don't hold lock when calling rtnl_unlock

bonding: Don't hold lock when calling rtnl_unlock

Change bond_mii_monitor to not hold any locks when calling rtnl_unlock,
as rtnl_unlock can sleep (when acquring another mutex in netdev_run_todo).

Bug reported by Makito SHIOKAWA <mshiokawa@miraclelinux.com>, who
included a different patch.
