Combine UART_CLEAR_FIFO and UART_USE_FIFO into one capability -
UART_CAP_FIFO.  There is only one UART with an unused FIFO - ST16650.
Since we check the fifo size before enabling, we maintain the
existing behaviour.

Some UARTs give us a transmit interrupt when the TX FIFO is less
than half empty.  This means we should not transfer a FIFO-full
of data to the device.  Introduce "tx_loadsz" to indicate the
size of this transfer.

This structure replaces serial_uart_config to allow the 8250 driver
to extend it without breaking all the other users.

Move "clear fifo" into separate function dependent on
UART_CLEAR_FIFO capability.  We take note of the comment about
Lucent Venus and always use the two-stage enable-then-clear as
we do on startup.

* long constant in a.out.h
* missing cast to pointer in pgtable.h
* removed useless __chk_user_ptr() in get_user() and put_user() - with fixed
  typeof handling in sparse we are getting the check from
 	__typeof__(*(ptr)) __user *__pu_addr = (ptr);			\
  anyway, so __chk_user_ptr() is redundant there.

It used to create totally impossible resource trees in some
circumstances where it was asked to insert a conflicting
resource. We never noticed, because it wasn't used that much.

Make it return the proper error instead.

~0x0UL passed in u32 argument will do what the authors wanted, but it's
a hell of a silly way to spell ~0U on 32bit boxen and it generates warnings on
64bit boxen (we get correct value after truncation, but compiler doesn't
know that ;-)

When I moved sparc64 over to HZ==1000 this added some
problems to the udelay() handling.  Specifically, with
slower cpus we could now get underflows to zero for
things like udelay(1) due to the order of multiplies
and shifts.

Fix this, and move it out to arch/sparc64/lib/delay.c
so it is easier to tinker with this in the future and
also to optimize away one of the multiplies for the
constant delay case just like other platforms do.

CAPI skb freeing fix. On sending, the hardware/low-level
driver may free a skb on no error only. The application/core
side must take care otherwise.

Author: Carsten Paeth, Armin Schindler

Whether a brainfart or a mismerge, I inadvertently broke PA-RISC during
the fork_by_hand()/init_idle() consolidation.

The following patch repairs a compilebug/thinko pair, consisting of the
use of an undeclared variable cpunum, and not attempting fork_idle()
until after the check for IS_ERR(idle) reported by James Bottomley.
