Remove the legacy power management code from the 68328 serial driver.
It is not used, and there is no current kernel support for power
management on the 68328.

This avoids xtime lag seen with dynticks, because while 'xtime' itself
is still not updated often, we keep a 'xtime_cache' variable around that
contains the approximate real-time that _is_ updated each time we do a
'update_wall_time()', and is thus never off by more than one tick.
IOW, this restores the original semantics for 'xtime' users, as long as
you use the proper abstraction functions (ie 'current_kernel_time()' or
'get_seconds()' depending on whether you want a timespec or just the
seconds field).
[ Updated Patch. As penance for my sins I've also yanked another #ifdef
that was added to avoid the xtime lag w/ hrtimers. ]

This avoids use of the kernel-internal "xtime" variable directly outside
of the actual time-related functions. Instead, use the helper functions
that we already have available to us.
This doesn't actually change any behaviour, but this will allow us to
fix the fact that "xtime" isn't updated very often with CONFIG_NO_HZ
(because much of the realtime information is maintained as separate
offsets to 'xtime'), which has caused interfaces that use xtime directly
to get a time that is out of sync with the real-time clock by up to a
third of a second or so.

Testing the wrong bit caused kvm not to disable nx on the guest when it is
disabled on the host (an mmu optimization relies on the nx bits being the
same in the guest and host).
This allows Windows to boot when nx is disabled on te host (e.g. when
host pae is disabled).

We didn't actually propogate the flag we pass into setup_indirect_pci()
to set indirect_type and thus were getting the wrong endianness if
PPC_INDIRECT_TYPE_BIG_ENDIAN was set.
Also, we need to or in additional flags rather than just doing a

We can't mark the whole thing init because there are dependencies
in bootloaders that assume that _start, or whatever the image
entry value, is 2 instructions before the "HdrS" signature.
In fact, TILO assumes this entry is always at 0x4000, yikes!
Also, right after the bootloader info area there are OBP strings and
values that get used later in the boot process, and those are not all
provably .init yet.
