mac80211-hwsim is a debugging tool for mac80211, and as such
it can very well verify that mac80211 isn't passing junk to
drivers, especially the vif pointer is prone to this because
for vlan interfaces the AP interface pointer needs to be passed.

I've been chasing Jeff about this for months. Jeff added the Marvell
device identifiers to the ahci driver without making the AHCI driver
handle the PATA port. This means a lot of users can't use current
kernels and in most distro cases can't even install.
This has been going on since March 2008 for the 6121 Marvell, and late 2007
for the 6145!!!
This was all pointed out at the time and repeatedly ignored. Bugs assigned
to Jeff about this are ignored also.
To quote Jeff in email
> "Just switch the order of 'ahci' and 'pata_marvell' in
> /etc/modprobe.conf, then use Fedora's tools regenerate the initrd.
> See? It's not rocket science, and the current configuration can be

(Which isn't trivial, isn't end user, shouldn't be needed, and as it usually
breaks at install time is in fact impossible)
To quote Jeff in August 2007
> " mv-ahci-pata
> Marvell 6121/6141 PATA support. Needs fixing in the 'PATA controller
> command' area before it is usable, and can go upstream."
Only he add the ids anyway later and caused regressions, adding a further
id in March causing more regresions.
The actual fix for the moment is very simple. If the user has included
the pata_marvell driver let it drive the ports. If they've only selected
for SATA support give them the AHCI driver which will run the port a fraction
faster. Allow the user to control this decision via ahci.marvell_enable as
a module parameter so that distributions can ship 'it works' defaults and
smarter users (or config tools) can then flip it over it desired.

ACPI PMTMR fails. On those chipsets, we need to read out the timer value
at least three times to get a correct result, for every once in a while
(i.e. within a 3 ns window every 69.8 ns) the read returns a bogus
result. During normal operation we work around this issue, but during
initialization reading a bogus value may lead to -EINVAL even though the
hardware is usable.
Thanks to Andreas Mohr for spotting this issue.

mmc_block_open() increments md->usage although it returns with -EROFS when
default mounting a MMC/SD card with write protect switch on. This
reference counting bug prevents /dev/mmcblkX from being released on card
removal, and situation worsen with reinsertion until the minor number
range runs out.

Fix regression tracked as http://bugzilla.kernel.org/show_bug.cgi?id=11361
and caused by commit f735a2a1a4 ("[netdrvr]
forcedeth: setup wake-on-lan before shutting down") that makes network
adapters integrated into the NVidia MCP55 chipsets fail to work in kexeced
kernels. The problem appears to be that if the adapter is put into D3_hot
during ->shutdown(), it cannot be brought back into D0 after kexec (ref.
http://marc.info/?l=linux-kernel&m=121900062814967&w=4). Therefore, only
put forcedeth into D3 during ->shutdown() if the system is to be powered
off.

Both p54pci and p54usb uses a good chunk of device specific code to
get the data from the device's eeprom into the drivers memory.
So, this patch reduces the code size and will it make life easier if
someone wants to implement ethtool eeprom dumping features.

This patch greatly reduces one of biggest memory waste in the driver.
The firmware headers provides the right values for extra head-/tailroom

There's been a patch floating around for toshiba_acpi that exports an ad-hoc
/proc interface to toggle the bluetooth adapter in a large number of Toshiba
laptops. I'm not sure if it's still relevant for the latest models, but it is
still required for older models such as my Tecra M3.
This change pulls in the low level Toshiba-specific code from the old patch and
sets up an rfkill device and a polled input device to track the state of the
hardware kill-switch.
