For intel ones, ahci unconditionally OR'd 0xf to PCS. This isn't
correct for the following cases.* ich6/7m's which only implement P0 and P2 (0xf works fine tho)
* ich8/9's which have six ports and needs 0x3f to enable all ports
This patch updates PCS programming such that...
* port_map determined by ahci_save_initial_config() is OR'd instead of 0xf
* PCS is updated only if necessary (there are turned off enable bits)
port_map is determined from PORTS_IMPL PCI register which is
implemented as write or write-once register. If the register isn't
programmed, ahci automatically generates it from number of ports,
which is good enough for PCS programming. ICH6/7M are probably the
only ones where non-contiguous enable bits are necessary && PORTS_IMPL
isn't programmed properly but they're proven to work reliably with 0xf
anyway.Signed-off-by: Tejun Heo

Lots of work needed to bring it up to scratch but it does work so you can
now use the card. That makes it at least useful, especially as the other

Correct the logic for when we issue a set features for transfer mode
- If the device has IORDY and the controller has IORDY - set the mode
- If the device has IORDY and the controller does not - turn IORDY off

ACPI spec (ver 3.0a, p289) requires IDE power on/off executes ACPI _PSx
methods. As recently most PATA drivers use libata, this patch adds _PSx
method support in libata. ACPI spec doesn't mention if SATA requires the
same _PSx method.Signed-off-by: Shaohua Li

Historically word 48 in the identify data was used to mean 32bit I/O
was supported for VLB IDE etc. ATA8 reassigns this word to the Trusted
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 testWhile we are at it the current drafts have a flaw where it may not be
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)Finally as with CPRM print a warning so that the user knows they may
not be able to full access and use the device.Signed-off-by: Alan Cox

When we set the MFGPT timer tick, there is a chance that we'll
immediately assert an event. If for some reason the IRQ routing
for this clock has been setup for some other purpose, then we
could end up firing an interrupt into the SMM handler or worse.This rearranges the timer tick init function to initalize the handler
before we set up the MFGPT clock to make sure that even if we get
an event, it will go to the handler.Furthermore, in the handler we need to make sure that we clear the
event, even if the timer isn't running.Signed-off-by: Jordan Crouse

The extra rom[0] check is flagging valid temperatures as invalid when
there is already a CRC data transmission check.w1_therm_read_bin()
if (rom[8] == crc && rom[0])
verdict = 1;Requiring rom[0] to be non-zero will flag as invalid temperature
conversions when the low byte is zero, specifically the temperatures 0C,
16C, 32C, 48C, -16C, -32C, and -48C.The CRC check is produced on the device for the previous 8 bytes and is
required to ensure the data integrity in transmission. I don't see why the
extra check for rom[0] being non-zero is in there. Evgeniy Polyakov didn't
know either. Just for a check I unplugged the sensor, executed a
temperature conversion, and read the results. The read was all ff's, which
also failed the CRC, so it doesn't need to protect against a disconnected
sensor.I have more extensive patches in the work, but these two trivial ones will
do for today. I would like to hear from people who use the ds2490 USB to
one wire dongle. 1 if you would be willing to test the patches as I
currently only have the one sensor on a short parisite powered wire, 2 if
there is any cheap sources for the ds2490.Signed-off-by: David Fries

Correct the decoding of negative C temperatures. The code did a binary OR
of two bytes to make a 16 bit value, but assignd it to an integer. This
caused the value to not be sign extended and to loose that it was a
negative number in the assignment.Before the patch (in my freezer),

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.Systems where this problem has been reported:

setting cpu share to 1 causes hangs, as reported in:
http://bugzilla.kernel.org/show_bug.cgi?id=9779
as the default share is 1024, the values of 0 and 1 can indeed
cause problems. Limit it to 2 or higher values.These values can only be set by the root user - but still it
makes sense to protect against nonsensical values.Signed-off-by: Ingo Molnar

tracked it down to this commit and confirmed that reverting the patch
restores the correct behaviour. It's too late in the release cycle to
find a better solution than reverting the commit to avoid regressions.Signed-off-by: Thomas Gleixner

In linux-2.6.24-rc1, security/commoncap.c:cap_inh_is_capped() was
introduced. It has the exact reverse of its intended behavior. This
led to an unintended privilege esculation involving a process'
inheritable capability set.To be exposed to this bug, you need to have Filesystem Capabilities
enabled and in use. That is:- CONFIG_SECURITY_FILE_CAPABILITIES must be defined for the buggy code
to be compiled in.- You also need to have files on your system marked with fI bits raised.

The JMPRS register on Malta boards keeps a 32-bit CPU-endian
value. The readw() function assumes that the value it reads is a
little-endian 16-bit number. Therefore, using readw() to obtain
the value of the JMPRS register is a mistake. This error leads
to incorrect reading of the PCI clock frequency on big-endian
during board start-up.Change readw() to __raw_readl().
This was tested by injecting a call to printk() and verifying
that the value of the jmpr variable was consistent with current
setting of the JP4 "PCI CLK" jumper.Signed-off-by: Dmitri Vorobiev

Commit "96793b482540f3a26e2188eaf75cb56b7829d3e3" (Add ICMPMsgStats
MIB (RFC 4293)) made a mistake.In that patch, David L added a icmp_out_count() in
ip_push_pending_frames(), remove icmp_out_count() from
icmp_reply(). But he forgot to remove icmp_out_count() from
icmp_send() too. Since icmp_send and icmp_reply will call
icmp_push_reply, which will call ip_push_pending_frames, a duplicated
increment happened in icmp_send.This patch remove the icmp_out_count from icmp_send too.

When unregistering the rtnl_link_ops, all existing devices using
the ops are destroyed. With nested devices this may lead to a
use-after-free despite the use of for_each_netdev_safe() in case
the upper device is next in the device list and is destroyed
by the NETDEV_UNREGISTER notifier.The easy fix is to restart scanning the device list after removing
a device. Alternatively we could add new devices to the front of
the list to avoid having dependant devices follow the device they
depend on. A third option would be to only restart scanning if
dev->iflink of the next device matches dev->ifindex of the current
one. For now this seems like the safest solution.With this patch, the veth rtnl_link_ops unregistration can use
rtnl_link_unregister() directly since it now also handles destruction
of multiple devices at once.Signed-off-by: Patrick McHardy
