Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.

These symbols are only used in the file that they are defined in,
so they should not be in the global namespace.

scanlog.c is only compiled on pSeries.  Thus, this patch moves it to
platforms/pseries.

Built and booted on pSeries LPAR (ARCH=powerpc and ARCH=ppc64).  Built
for iSeries (ARCH=powerpc).

Use msleep_interruptible() instead of schedule_timeout() in ppc64-specific
code to cleanup/simplify the sleeping logic.  Change the units of the
parameter of do_event_scan_all_cpus() to milliseconds from jiffies.  The
return value of rtas_extended_busy_delay_time() was incorrectly being used
as a jiffies value (it is actually milliseconds), which is fixed by using
the value as a parameter to msleep_interruptible().  Also, use
rtas_extended_busy_delay_time() in another case where similar logic is
duplicated.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
