This patch adds the capability to the mpc52xx-uart to report framing
errors, parity errors, breaks and overruns to userspace. These values
may be requested in userspace by using the ioctl TIOCGICOUNT.

Fix the usage of CONFIG_SERIAL_SAMSUNG_UARTS in several places
in the kernel where it had been missed. This finishes fixing a
long standing issue where S3C2443 and S3C64XX could not use the

Under qemu there is a race between the TDxE read-and-clear and the SCxTDR
write. While on hardware it can be gauranteed that the read-and-clear
will happen prior to the character being written out, no such assumption
can be made under emulation. As this path happens with IRQs off and the
hardware itself doesn't care about the ordering, move the SCxTDR write
until after the read-and-clear.

The atmel_serial driver is mismanaging its clock by leaving it on at all
times ... the whole point of clock management is to leave it off unless
it's actively needed, which conserves power!!
Although the kernel doesn't actually hang without my fix, it does
discard quite a lot of early console output.
The result still looks correct:
usart users= 1 on 35000000 Hz, for atmel_usart.0
usart users= 0 off 35000000 Hz, for atmel_usart.2
when using ttyS0 as serial console.

This merges branches irq/genirq, irq/sparseirq-v4, timers/hpet-percpu
and x86/uv.
The sparseirq branch is just preliminary groundwork: no sparse IRQs are
actually implemented by this tree anymore - just the new APIs are added
while keeping the old way intact as well (the new APIs map 1:1 to
irq_desc[]). The 'real' sparse IRQ support will then be a relatively
small patch ontop of this - with a v2.6.29 merge target.
