This patch merges types.h into include/asm-powerpc. The only real change is
the removal of the include of linux/config.h from the 32-bit version - it
doesn't appear to be necessary.

This patch has been built on several different 32 and 64-bit platforms,
and booted on mpc8540_ads.

This patches the ppc32 and ppc64 versions of the headers and .c files
with helper functions for manipulating the performance counting
hardware.  As a side effect, it removes use of the term "perfmon" from
ppc32, thus avoiding confusion with the unrelated performance counter
interface from HP Labs also called "perfmon".

Built, but not booted, for g5, pSeries, iSeries, and 32-bit Powermac
with both ARCH=powerpc and ARCH=ppc{,64} as appropriate.

The _GLOBAL() macro is for text symbols only. Changed to using

We now use the merged time.c for both 32-bit and 64-bit compilation
with ARCH=powerpc, and for ARCH=ppc64, but not for ARCH=ppc32.
This removes setup_default_decr (folds its function into time_init)
and moves wakeup_decrementer into time.c.  This also makes an
asm-powerpc/rtc.h.

A few things change for consistency between ppc32 and ppc64:
idle functions return void; *_get_boot_time functions return
unsigned long (i.e. time_t) rather than filling in a struct rtc_time
(since that's useful to the callers and easier for pmac to
generate); *_get_rtc_time and *_set_rtc_time functions take
a struct rtc_time; irq_canonicalize is gone; nvram_sync returns
void.

This makes platform code use the smp_ops variable directly instead
of ppc_md.smp_ops, removes the two unused `data' and `wait' arguments
from the *_message_pass() functions, and removes the call to the
never-implemented smp_ops->space_timers() function.

We were initializing the btext stuff from prom_init(), thus breaking
the rule that all communication between prom_init() and the rest of
the kernel has to be via the flattened device tree.  This removes
the btext initialization calls from prom_init() and initializes it
instead after the device tree is unflattened.  It would be nice to
do it earlier, but that needs some more infrastructure to find the
properties we need in the flattened device tree.
