176f9c1804 ACPI: remove doubled status checking
There was a misplaced status test (two consequent tests without a
statement in between) in acpi_bus_init for ages.  Remove it, since the
function which should be checked (acpi_os_initialize1) has BUG_ONs on
failure paths.

This reverts commit 5ec5d38a1c8af255ffc481c81eef13e9155524b3.
because it caused spurious dmesg warmings.
We'll implement the check for off-limit ports
in a more clever way in the future.

ea8dbdd170 r8169: revert "r8169: read MAC address from EEPROM on init (2nd attempt)"
It fails on the following systems:
- RTL8169sc/8110sc (XID 18000000)
  reported by Tim Durack <tdurack@gmail.com> (x86)
- RTL8169sb/8110sb (XID 10000000)
  reported by Mikael Pettersson <mikpe@it.uu.se> (ARM)

The patch appeared to work on x86 for the following systems:
RTL8169sb/8110sb 10000000 PCI   (EXT)
RTL8110s         04000000 PCI   (EXT)
RTL8102e         24a00000 PCI-E (LOM)
RTL8168c/8111c   3c2000c0 PCI-E (LOM)
RTL8168b/8111b   38000000 PCI-E (LOM)
RTL8168b/8111b   38000000 PCI-E (EXT)

The patch exposes two problems:
1) while not completely wrong, mac addresses are not read correctly
   from the EEPROM
2) the MAC address registers are not correctly set

5a89392225 mv643xx_eth: fix unicast address filter corruption on mtu change
When mv643xx_eth_open() is called to up an interface, port_start()
will first re-program the unicast address filter, and then
re-initialise the PORT_CONFIG register, but that will disable unicast
promiscuous mode if it was enabled by the unicast address filter setup.

This isn't a problem on ifconfig up, as ->set_rx_mode() will be called
shortly afterwards which will program the filters again, but it does
trigger when changing the MTU, which calls mv643xx_eth_stop() and then
mv643xx_eth_open() by hand to repopulate the receive rings with skbuffs
of the new size.

Swap the initialisation of the PORT_START register and the call to
the unicast filter setup function to fix this.

e9c1670c2a ata_piix: add workaround for Samsung DB-P70
Samsung DB-P70 somehow botched the first ICH9 SATA port.  The board
doesn't expose the first port but somehow SStatus reports link online
while failing SRST protocol leading to repeated probe failures and
thus long boot delay.

Because the BIOS doesn't carry any identifying DMI information, the
port can't be blacklisted safely.  Fortunately, the controller does
have subsystem vendor and ID set.  It's unclear whether the subsystem
IDs are used only for the board but it can be safely worked around by
disabling SIDPR access and just using SRST works around the problem.
Even when the workaround is triggered on an unaffected board the only
side effect will be missing SCR access.

e3e4385f61 libata: Keep shadow last_ctl up to date during resets
libata keeps a shadow copy of the ATA CTL register (which is write only),
and only writes to the hardware when the required value doesn't match
the shadow. However this copy wasn't being maintained when performing
reset functions. This could cause problems for the first operation after
a reset when the correct value might not be written to the CTL register.

This problem was observed when hotplugging a drive: the identify command
was being issued with interrupts enabled, when they should have been
disabled.

can just move to the standard device_for_each_child() API.

The ps3vram driver exposes unused video RAM on the PS3 as a block device

The new driver is ca. 50% faster for reading, and ca. 10% for writing.

5f77af9326 V4L/DVB (10972): zl10353: i2c_gate_ctrl bug fix
zl10353 i2c-gate was always closed and due to that devices having tuner
behind i2c-gate were broken. Add module configuration which allows disabling
i2c-gate only when really needed.

c12e56ef69 RDMA/nes: Don't allow userspace QPs to use STag zero
STag zero is a special STag that allows consumers to access any bus
address without registering memory.  The nes driver unfortunately
allows STag zero to be used even with QPs created by unprivileged
userspace consumers, which means that any process with direct verbs
access to the nes device can read and write any memory accessible to
the underlying PCI device (usually any memory in the system).  Such
access is usually given for cluster software such as MPI to use, so
this is a local privilege escalation bug on most systems running this
driver.

The driver was using STag zero to receive the last streaming mode
data; to allow STag zero to be disabled for unprivileged QPs, the
driver now registers a special MR for this data.

1ba869ec58 acer-wmi: fix regression in backlight detection
Currently we disable the Acer WMI backlight device if there is no ACPI
backlight device.  As a result, we end up with no backlight device at all.
 We should instead disable it if there is an ACPI device, as the other
laptop drivers do.  This regression was introduced in febf2d9 ("Acer-WMI:
fingers off backlight if video.ko is serving this functionality").

Each laptop driver with backlight support got a similar change around
febf2d9.  The changes to the other drivers look correct; see e.g.
a598c82f for a similar but correct change.  The regression is also in
2.6.28.

7c48ed3383 mmc: s3cmci: fix s3c2410_dma_config() arguments.
The s3cmci driver is calling s3c2410_dma_config with incorrect data for
the DCON register.  The S3C2410_DCON_HWTRIG is implicit in the channel
configuration and the device selection of S3C2410_DCON_CH0_SDI is
incorrect as the DMA system may not select channel 0.

8d0df7a3d1 drivers/w1/masters/w1-gpio.c: fix read_bit()
W1 master implementations are expected to return 0 or 1 from their
read_bit() function.  However, not all platforms do return these values
from gpio_get_value() - namely PXAs won't.  Hence the w1 gpio-master needs
to break the result down to 0 or 1 itself.
