36da4d869f [TG3]: Fix 2nd ifup failure on 5752M.
This fixes a bug reported in:

http://bugzilla.kernel.org/show_bug.cgi?id=7438

tg3_close() turns off the PHY if WoL and ASF are both disabled.  On
the next tg3_open(), some devices such as the 5752M will not be
brought up correctly without a PHY reset early in the reset sequence.
The PHY clock is needed for some internal MAC blocks to function
correctly.

This problem is fixed by always resetting the PHY early in
tg3_reset_hw() when it is called from tg3_open() or tg3_resume().
tg3_setup_phy() can then be called later in the sequence without the
reset_phy parameter set to 1, since the PHY reset is already done.

Update version to 3.68.

It looks like device registration in drivers/char/ipmi/ipmi_si_intf.c was

18ee91fa98 USB: use MII hooks only if CONFIG_MII is enabled
Fix mcs7830 patch

The recent mcs7830 update to make the MII support sharable goofed various
pre-existing configurations in two ways:

  - it made the usbnet infrastructure reference MII symbols even
    when they're not needed in the kernel being built

  - it didn't enable MII along with the mcs7830 minidriver

This patch fixes these two problems.

However, there does seem to be a Kconfig reverse dependency bug in that MII
gets wrongly enabled in some cases (like USBNET=y and USBNET_MII=n); I think
I've noticed that same problem in other situations too.  So the result can
mean kernels being bloated by stuff that's needlessly enabled ... better
than wrongly being disabled, but contributing to bloat.

68717950e1 hid-core: big-endian fix fix
Adam Kropelin had posted 32-bit fix in June 2005 about two weeks after I
originally had posted my fixes for big endian support.  Adam has a UPS
device which reports LINEV using 32-bits.

Added comments to describe the limitations of the code.

extract() is the same version I posted earlier and tested in user space. 
Made similar changes to implement() routine.  I've written (and will
shortly post) a test for implement().  Code tested on C3600 (parisc) with
USB keyboard/mouse attached.


I've dropped test_implement.c and a few other user space test programs on
http://iou.parisc-linux.org/~grundler/tests/

bb44c308ee PCI: Let PCI_MULTITHREAD_PROBE depend on BROKEN
PCI_MULTITHREAD_PROBE is an interesting feature, but in its current state
it seems to be more of a trap for users who accidentally enable it.

This patch lets PCI_MULTITHREAD_PROBE depend on BROKEN for 2.6.19.

The intention is to get this patch reversed in -mm as soon as it's in
Linus' tree, and reverse it for 2.6.20 or 2.6.21 after the fallout of
in-kernel problems PCI_MULTITHREAD_PROBE causes got fixed.

(akpm: I get enough bug reports already)

c5dec9fb24 V4L/DVB (4751): Fix DBV_FE_CUSTOMISE for card drivers compiled into kernel
When a front-end is disabled, card drivers that use it are compiled with
a stub version of the front-end's attach function.  This way they have no
references to the front-end's code and don't need it to be loaded.
If a card driver is compiled into the kernel, and a front-end is a
module, then that front-end is effectively disabled wrt the card driver. 
In this case, the card driver should get the stub version.  This was not
happening.
The stub vs real attach function selection is changed so that when the
front-end is a module the real attach function is only used if the card
driver is a module as well.  This means a module front-end will be
supported by card drivers that are modules and not supported by card
drivers compiled into the kernel.

ecba77f246 V4L/DVB (4785): Budget-ci: Change DEBIADDR_IR to a safer default
The IR chip has no address decoding, so the IR data is always present in 
the high byte when doing a read from the saa7146 chip. This means that 
the DEBI address used is irrelevant to the IR decoding logic.
DEBI addresses 0x1XXX are mapped to the registers on the CI module 
itself, but only the lowest two bits are actually used (see EN50221, 
section A.2.2.1), meaning that 0x1234 is equivalent to 0x1000 which maps 
to register 0 (the data register). A read from the data register is 
supposed to be preceded by a read from the size register, so some CI 
modules will be confused (the AlphaCrypt CAM will hang completely).
The attached patch changes the address used when reading the IR data to 
use 0x4000 instead. This is the CI version address, which is a safer 
default, works with the AlphaCrypt CAM and matches the behaviour of the 
Windows driver (AFAIK).

1244a19cde [PATCH] ahci: fix status register check in ahci_softreset
ahci_softreset() used to use ahci_tf_read() which reads D2H_REG area
to check for the Status register.  However, this area is zeroed on
initialization and not set by initial signature FIS.  Replace it with
ahci_check_status().

This bug prevented CLO code from being activated whenever BSY and/or
DRQ is set prior to softreset.  This fix makes
AHCI_FLAG_RESET_NEEDS_CLO flag redundant.

441cbd8dac [POWERPC] Fix various offb issues
This patch fixes a few issues in offb:

 - A test was inverted causing the palette hack to never work
(no device node was passed down to the init function)

 - Some cards seem to have their assigned-addresses property in a random
order, thus we need to try using of_get_pci_address() first, which will
fail if it's not a PCI device, and fallback to of_get_address() in that
case. of_get_pci_address() properly parsees assigned-addresses to test
the BAR number and thus will get it right whatever the order is.

 - Some cards (like GXT4500) provide a linebytes of 0xffffffff in the
device-tree which does no good. This patch handles that by using the
screen width when that happens. (Also fixes btext.c while at it).

 - Add detection of the GXT4500 in addition to the GXT2000 for the
palette hacks (we use the same hack, palette is linear in register space
at offset 0x6000).

df6d7c94b0 [PATCH] bcm43xx: fix unexpected LED control values in BCM4303 sprom
The bcm43xx driver uses 4 locations in the devices sprom to determine
the behavior of the leds. Certain defaults are assigned if all bits are
set in those locations. On at least one BCM4303 chip, the sprom contains
values other than the default, which executes an assertion placed in the
default case of a following switch statement. This patch makes the leds
on the above mentioned interface behave correctly. In addition, it limits
the number of logged messages to 20 for the case of unexpected values in
the sprom locations.

81e171b95d [PATCH] bcm43xx: Fix low-traffic netdev watchdog TX timeouts
This fixes a netdev watchdog timeout problem.
The software needs to call netif_tx_disable before running the
hardware calibration code. The problem condition can be shown by the
following timegraph.

|---5secs - ~10 jiffies time---|---|OOPS
^                              ^
last real TX                   periodic work stops netif

At OOPS, the following happens:
The watchdog timer triggers, because the timeout of 5secs
is over. The watchdog first checks for stopped TX.
_Usually_ TX is only stopped from the TX handler to indicate
a full TX queue. But this is different. We need to stop TX here,
regardless of the TX queue state. So the watchdog recognizes
the stopped device and assumes it is stopped due to full
TX queues (Which is a _wrong_ assumption in this case). It then
tests how far the last TX has been in the past. If it's more than
5secs (which is the case for low or no traffic), it will fire
a TX timeout.

115e222d53 [PATCH] hostap_plx: fix CIS verification
The length of the manfid CIS should be at least 4, and it's normally 4.
It's incorrect to require it to be at least 5.  This breaks support for
most (if not all) cards.

The right place to ensure that we don't access beyond the CIS buffer is
to strengthen another check.  Make sure that the next tuple begins at
least at the CIS buffer end (in which case we stop processing) or
before that.

cf0e812f0e [PATCH] sata_sis: fix flags handling for the secondary port
sis_init_one() modifies probe_ent->port_flags after allocating and
initializing it using ata_pci_init_native_mode().  This makes port_flags
for the secondary port (probe_ent->pinfo2->flags) go out of sync resulting
in misdetection of device due to incorrectly initialized SCR access flag.

This patch make probe_ent alloc/init happen after the final port flags
value is determined.  This is fragile but probe_ent and all the related
mess are scheduled to go away soon for exactly this reason.  We just need
to hold everything together till then.

This has been spotted and diagnosed and tested by Patrick McHardy.

0ca43235b3 [PATCH] sky2: netpoll on dual port cards
The sky2 driver uses a single NAPI poll routine for both ports on dual ported
cards (because there is a single IRQ and status ring). Netpoll makes assumptions
about the relationship between network device and NAPI that aren't correct
on the second port, this will cause the port to never clear work.

Most systems, just have single port, so not a big issue.
The easy fix is just make the second port, not netpoll capable.

2d38caba5f [PATCH] ep93xx_eth: fix RX/TXstatus ring full handling
Ray Lehtiniemi reported that an incoming UDP packet flood can lock up
the ep93xx ethernet driver.  Herbert Valerio Riedel noted that due to
the way ep93xx_eth manages the RX/TXstatus rings, it cannot distinguish
a full ring from an empty one, and correctly suggested that this was
likely to be causing this lockup to occur.

Instead of looking at the hardware's RX/TXstatus ring write pointers
to determine when to stop reading from those rings, we should just check
every individual RX/TXstatus descriptor's valid bit instead, since there
is no other way to distinguish an empty ring from a full ring, and if
there is a descriptor waiting, we take the hit of reading the descriptor
from memory anyway.

This reverts commit a2b98a697f.

As per Guennadi Liakhovetski, the mac address change support code breaks
some normal uses (_without_ any address changes), and until it's all
sorted out, we're better off without it.

Says Francois:

  "Go revert it.

   Despite what I claimed, I can not find a third-party confirmation by
   email that it works elsewhere.

   It would probably be enough to remove the call to
   __rtl8169_set_mac_addr() in rtl8169_hw_start() though."

9468613b2b [ARM] Fix suspend oops caused by PXA2xx PCMCIA driver
The PXA2xx PCMCIA driver was registering a device_driver with the
platform_bus_type.  Unfortunately, this causes data outside the
device_driver structure to be dereferenced as if it were a
platform_driver structure, causing an oops.  Convert the PXA2xx
core driver to use the proper platform_driver structure.

735a7ffb73 [PATCH] drivers: wait for threaded probes between initcall levels
The multithreaded-probing code has a problem: after one initcall level (eg,
core_initcall) has been processed, we will then start processing the next
level (postcore_initcall) while the kernel threads which are handling
core_initcall are still executing.  This breaks the guarantees which the
layered initcalls previously gave us.

IOW, we want to be multithreaded _within_ an initcall level, but not between
different levels.

Fix that up by causing the probing code to wait for all outstanding probes at
one level to complete before we start processing the next level.

3560cc5ec3 PCI: Remove quirk_via_abnormal_poweroff
My K8T800 mobo resumes fine from suspend to ram with and without patch
applied against 2.6.18.

quirk_via_abnormal_poweroff makes some boards not boot 2.6.18, so IMO patch
should go to head, 2.6.18.2 and everywhere "ACPI: ACPICA 20060623" has been
applied.


Remove quirk_via_abnormal_poweroff

Obsoleted by "ACPI: ACPICA 20060623":
<snip>
    Implemented support for "ignored" bits in the ACPI
    registers.  According to the ACPI specification, these
    bits should be preserved when writing the registers via
    a read/modify/write cycle. There are 3 bits preserved
    in this manner: PM1_CONTROL[0] (SCI_EN), PM1_CONTROL[9],
    and PM1_STATUS[11].

2449e06a56 PCI: reset pci device state to unknown state for resume
Considering below scenario:
1.Unload a PCI device's driver, the device ->current remains in PCI_D0.
2.Do suspend/resume circle. After that, BIOS puts the device to D3.
3.Reload the device driver. The calling pci_set_power_state in the
driver can't change the state to D0, as set_power_state thinks the
device is already in D0.

A bug is reported at http://bugzilla.kernel.org/show_bug.cgi?id=6024
Pat attached a patch at
http://marc.theaimsgroup.com/?l=linux-pci&m=114049761428561&w=2 for this
issue, but it's lost. As pci_set_power_state can handle D3 -> D0
correctly (restore config space), I simplified Patrick's patch.

4708b5faf7 [PATCH] pcmcia: update alloc_io_space for conflict checking for multifunction PC card
Some PCMCIA cards do not mention specific IO addresses in the CIS.  In that
case, inside the alloc_io_space function, conflicts are detected (the
function returns 1) for the second function of a multifunction card unless
the length of IO address range required is greater than 0x100.

The following patch will remove this conflict checking for a PCMCIA
function which had not mentioned any specific IO address to be mapped from.

The patch is tested for Linux kernel 2.6.15.4 and works fine in the above
case and is as suggested by Dave Hinds.

More correct AT91 CF wakeup logic ... only enable/disable the IRQ wakeup
capability, not the IRQ itself.  That way the we know that the IRQ will be

Most of the pin multiplexing setup has moved to the devices.c setup code.

8883c1f182 [SCSI] aic79xx: Fixup external device reset
Whenever an external device is resetted we really have to take
care to keep the channel in sync. Just notifying SCSI-ML and retry
is not enough as we have to make sure the SCSI bus is not getting
confused, either.
So whenever we detect an external reset we rewrite the command to
TUR, disable packetized command and notify the internal engine
that an abort has happened. This way we trigger a proper bus
reset sequence and all devices will be renegotiated properly.
Kudos to Justin Gibbs and Luben Tuikov for this idea.

since 5 lines above we goto again if (rc).

43a145a344 [SCSI] iscsi class: fix slab corruption during restart
The transport class recv mempools are causing slab corruption.
We could hack around netlink's lack of mempool support like dm,
but it is just too ulgy (dm's hack is ugly enough :) when you need
to support broadcast.

This patch removes the recv pools. We have not used them even when
we were allocting 20 MB per session and the system only had 64 MBs.
And we have no pools on the send side and have been ok there. When
Peter's work gets merged we can use that since the network guys
are in favor of that approach and are not going to add mempools
everywhere.

Early ISP2432 parts have a known hardware issue when coming
out of a D3 hot state.  This issue can result in a hung PCIe
link.  Recent firmwares contain a workaround whereby the
stop-firmware mailbox command prevents the ISP from entering
the D3 hot state.

In order to ensure that the workaround succeeded the driver
must verify that the stop-firmware mailbox command completes
successfully.  In the event of a failure, the driver
attempts a shutdown-retry after resetting the ISP and
re-executing firmware.
