4b1f8a99a2 [PATCH] ipw2200: Add IEEE80211_RADIOTAP_TSFT for promiscuous mode
The ipw2200 BSS firmware passes on the TSF information within ipw_rx_frame,
but monitor firmware doesn't. I add back the IEEE80211_RADIOTAP_TSFT flags
so that we can get the MAC timestamp if we use the rtap interface. We will
see the MAC timestamp equals to zero if we capture the packets with a
monitor mode interface. But this is the expected behaviour.

9cdac9657f [PATCH] zd1211rw: Support for multicast addresses
Support for multicast adresses is implemented by supporting the
set_multicast_list() function of the network device. Address
filtering is supported by a group hash table in the device.

This is based on earlier work by Benoit Papillaut. Fixes multicast packet
reception and ipv6 connectivity:

ee28b0da10 [PATCH] remote memory corruptor in ibmtr.c
ip_summed changes last summer had missed that one.  As the result,
we have ip_summed interpreted as CHECKSUM_PARTIAL now.  IOW,
->csum is interpreted as offset of checksum in the packet.  net/core/*
will both read and modify the value as that offset, with obvious
reasons.  At the very least it's a remote memory corruptor.

15e9b586e0 [S390] Reset infrastructure for re-IPL.
In case of re-IPL and diag308 doesn't work we have to reset all devices
manually and wait synchronously that each reset finished.
This patch adds the necessary infrastucture and the first exploiter of it.

Subsystems that need to add a function that needs to be called at re-IPL
may register/unregister this function via

struct reset_call {
	struct reset_call *next;
	void (*fn)(void);
};

void register_reset_call(struct reset_call *reset);
void unregister_reset_call(struct reset_call *reset);

When the registered function get called the context is:

- all cpus beside the current one are stopped
- all machine checks and interrupts are disabled
- prefixing is disabled
- a default machine check handler is available for use

The registered functions may not take any locks are sleep.

For the common I/O layer part of this patch:

Introduce a reset_call css_reset that does the following:
- clear all subchannels
- perform a rchp on all channel paths and wait for the resulting
  machine checks
This replaces the calls to clear_all_subchannels() and
cio_reset_channel_paths() for kexec and ccw reipl. reipl_ccw_dev() now
uses reipl_find_schid() to determine the subchannel id for a given
device id.
Also remove cio_reset_channel_paths() and friends since they are not
needed anymore.

e22ba7e381 [POWERPC] ps3: multiplatform build fixes
A few code paths need to check whether or not they are running
on the PS3's LV1 hypervisor before making hcalls. This introduces
a new firmware feature bit for this, FW_FEATURE_PS3_LV1.

Now when both PS3 and IBM_CELL_BLADE are enabled, but not PSERIES,
FW_FEATURE_PS3_LV1 and FW_FEATURE_LPAR get enabled at compile time,
which is a bug. The same problem can also happen for (PPC_ISERIES &&
!PPC_PSERIES && PPC_SOMETHING_ELSE). In order to solve this, I
introduce a new CONFIG_PPC_NATIVE option that is set when at least
one platform is selected that can run without a hypervisor and then
turns the firmware feature check into a run-time option.

The new cell oprofile support that was recently merged does not
work on hypervisor based platforms like the PS3, therefore make
it depend on PPC_CELL_NATIVE instead of PPC_CELL. This may change
if we get oprofile support for PS3.

7eebde700f [POWERPC] Souped-up of_platform_device support
This patch first splits of_device.c and of_platform.c, the later containing
the bits relative to of_platform_device's. On the "breaks" side of things,
drivers uisng of_platform_device(s) need to include asm/of_platform.h now
and of_(un)register_driver is now of_(un)register_platform_driver.

In addition to a few utility functions to locate of_platform_device(s),
the main new addition is of_platform_bus_probe() which allows the platform
code to trigger an automatic creation of of_platform_devices for a whole
tree of devices.

The function acts based on the type of the various "parent" devices encountered
from a provided root, using either a default known list of bus types that can be
"probed" or a passed-in list. It will only register devices on busses matching
that list, which mean that typically, it will not register PCI devices, as
expected (since they will be picked up by the PCI layer).

This will be used by Cell platforms using 4xx-type IOs in the Axon bridge
and can be used by any embedded-type device as well.

1be3770aa9 [POWERPC] Make EMAC use generic DCR access methods
This patch makes the EMAC driver use the new DCR access methods. It
doesn't yet uses dcr_map() and thus still only work with real DCRs.
This will be fixed in a later patch

ef9467f8f0 [SUNHME]: Fix for sunhme failures on x86
The following patch fixes the failure of sunhme drivers on x86 hosts
due to missing pci_enable_device() and pci_set_master() calls, lost 
during code refactoring. It has been filed as bugzilla bug #7502 [0] 
and Debian bug #397460 [1].

599b7202c5 [PATCH] sata_promise: PHYMODE4 fixup
This patch adds code to fix up the PHYMODE4 "align timing"
register value on second-generation Promise SATA chips.
Failure to correct this value on non-x86 machines makes
drive detection prone to failure due to timeouts. (I've
observed about 50% detection failure rates on SPARC64.)

The HW boots with a bad value in this register, but on x86
machines the Promise BIOS corrects it to the value recommended
by the manual, so most people have been unaffected by this issue.

After developing the patch I checked Promise's SATAII driver,
and discovered that it also corrects PHYMODE4 just like this
patch does.

This patch depends on the sata_promise SATAII updates
patch I sent recently.

800b399669 [PATCH] libata: always use polling IDENTIFY
libata switched to IRQ-driven IDENTIFY when IRQ-driven PIO was
introduced.  This has caused a lot of problems including device
misdetection and phantom device.

ATA_FLAG_DETECT_POLLING was added recently to selectively use polling
IDENTIFY on problemetic drivers but many controllers and devices are
affected by this problem and trying to adding ATA_FLAG_DETECT_POLLING
for each such case is diffcult and not very rewarding.

This patch makes libata always use polling IDENTIFY.  This is
consistent with libata's original behavior and drivers/ide's behavior.

8e16f94122 [PATCH] ahci: do not powerdown during initialization
ahci_init_controller() calls ahci_deinit_port() to make sure the
controller is stopped before initializing the controller.  In turn,
ahci_deinit_port() invokes ahci_power_down() to power down the port.
If the controller supports slumber mode, the link is put into it.

Unfortunately, some devices don't implement link powersaving mode
properly and show erratic behavior after link is put into slumber
mode.  For example, HL-DT-ST DVD-RAM GSA-H30N completely locks up on
slumber transition and can only be recovered with the *REAL* hard
reset - power removal and reapply.

Note that this makes the first probing reset different from all
others.  If the above dvd-ram is hotplugged after ahci is initialized,
no problem occurs because ahci is already fully initialized with phy
powered up.  So, this might also be the reason for other weird AHCI
initial probing abnormalities.

This patch moves power up/down out of port init/deinit and call them
only when needed.

Power down is now called only when suspending.  As system suspend
usually involves powering down 12v for storage devices, this shouldn't
cause problem even if the attached device doesn't support slumber
mode.  However, in partial power management and suspend failure cases,
devices might lock up after suspend attempt.  I thought about removing
transition to slumber mode altogether but ahci spec mandates it before
HBA D3 state transition.  Blacklisting such devices might be the
solution.
