SPI controller drivers return number of bytes actually transfered from
bitbang->txrx_bufs() method. This updates handling of short transfers (where
the transfer size is less than requested):
- Even zero byte short transfers should report errors;
- Include short transfers in the total of transferred bytes;
- Use EREMOTEIO (like USB) not EMSGSIZE to report short transfers
Short transfers don't normally mean invalid message sizes, but if the
underlying controller driver needs to use EMSGSIZE it can still do so.

The iSeries viodasd drivers does some very strange things with
scatterlists, one of these causing a BUG_ON to trigger when
scatterlist debugging is enabled due to initializing the
scatterlist with memset instead of sg_init_table().
This fixes it by using sg_init_table(). The rest of the stuff
it does to that poor list is still pretty awful but it will work.
I may look into fixing things in a nicer way some other time.

Currently, if drivers/macintosh/apm_emu is a module and the config
doesn't have CONFIG_SUSPEND we get:
ERROR: "pmu_batteries" [drivers/macintosh/apm_emu.ko] undefined!
ERROR: "pmu_battery_count" [drivers/macintosh/apm_emu.ko] undefined!
ERROR: "pmu_power_flags" [drivers/macintosh/apm_emu.ko] undefined!
on PPC32. The variables aren't wrapped in '#if defined(CONFIG_SUSPEND)'
so we probably shouldn't wrap the exports either. This removes the
CONFIG_SUSPEND part of the export, which fixes compilation on ppc32.

The PMU backlight code would kick in during sleep/resume even on
machines that use a different backlight method. This breaks
sleep on some PowerBooks.
This fixes it by adding a flag to indicate whether the backlight
is controlled by the PMU, and testing that before trying to use
the PMU to turn off the backlight during sleep.

i2c: chips subdirectory is deprecated
i2c: Keep client->driver and client->dev.driver in sync
i2c-amd756: Fix off-by-one
Some BIOSes have PNP motherboard devices with resources that
partially overlap PCI BARs. The PNP system driver claims these
motherboard resources, which prevents the normal PCI driver from
requesting them later.
This patch disables the PNP resources that conflict with PCI BARs
so they won't be claimed by the PNP system driver.
Of course, this only works if PCI devices have already been enumerated.
Currently this is the case because PCI devices are discovered before
any PNP init via this path:
acpi_pci_root_init() -> acpi_pci_root_add() -> pci_acpi_scan_root() ->
pci_scan_bus_parented() -> pci_scan_child_bus() -> ...
Avuton Olrich tested this and confirmed that it fixes his ALSA sound
card (see http://lkml.org/lkml/2008/1/27/168).

If an md array is "auto-read-only", then this appears in /proc/mdstat as

whereas if it is truely readonly, it appears as
