powerpc: Initialise paca->kstack before early_setup_secondary
As early setup calls down to slb_initialize(), we must have kstack
initialised before checking "should we add a bolted SLB entry for our kstack?"
Failing to do so means stack access requires an SLB miss exception to refill
an entry dynamically, if the stack isn't accessible via SLB(0) (kernel text
& static data). It's not always allowable to take such a miss, and
intermittent crashes will result.
Primary CPUs don't have this issue; an SLB entry is not bolted for their
stack anyway (as that lives within SLB(0)). This patch therefore only
affects the init of secondaries.

avoiding things like overflow of the mmap_sem if you use a really crazy

Note: Ideally the type in the structure should be atomic_long_t rather

be initialized statically -and- lib/rwsem.c does things like
sem->count = RWSEM_UNLOCKED_VALUE;

with one member and note typedefs of a scalar, it makes its really nasty.

USB: otg: twl4030: fix wrong assumption of starting state
The reset state of twl4030-usb is not sleeping, it starts
up awaken and we need to disable it if we have booted
with a disconnected cable to avoid over consumption on
the default state.
To avoid problems later, we read the current state of the
transceiver from the PHY_PWR_CTRL register. The bootloader
can, anyways, put the device to sleep before us.

USB: isp1760: use a write barrier to ensure proper ndelay timing
The ISP1760 has some timing requirements where it has to delay a short
period after a write to a register has started. However, this delay is
from the time the write hits the USB chip (the ISP1760), not from the
time where the processor started processing the write. So on a quick
enough processor, it is sometimes possible for the write to not hit the
device before we start delaying, and we then violate the part's timing
requirements, so things stop working.
To avoid all this, insert a write barrier after the register write and
before the timing delay/register read so we can guarantee we only start
counting time after the write has hit the device.

netfilter: fix CONFIG_COMPAT support

also compute the jumpstack size in the compat handlers.
Result is that "iptables -I INPUT -j userchain" turns into -j DROP.

ACPI_TOSHIBA needs LEDS support
Don't ask how ACPI_TOSHIBA got enabled on in desktop system's .config -
I don't know. But it has silently been there until I tried 2.6.36-rc2,
where it broke the build because I don't have LED support turned on.
Attached patch fixes things up.
(I had to change BACKLIGHT_CLASS_DEVICE to "depends" because otherwise
I get unsightly core dumps out of scripts/kconfig/conf).
