No need to explicitly zero out global variables.

         - removes 2.4 specific macros/inline functions
         - fix rum vs. rsm bug for psr.up
         - introduce cleaner PMC_IS_CONTROL() macro
         - only save the value of psr.up on ctxsw (not whole psr)"

	when bspstore happened to point to an RNaT-slot.
	Bug reported by Matt Chapman.

Here's a patch against your bk tree that keeps things building for sn2
(and working with the discontig patch applied).

  Add back IDE configuration.

	this also ensure we really do test the linker which will be
	used when building the gate DSO.

I _think_ I got this one right (at least, it booted on hw).  It should
allow generic kernels to include the sn2 code.

Updates the PCI routines for sn2.

Small fix for hwgfs on sn2.

Small patch to fixup the new mark_idle() stuff for sn2.

I think there are other 64p issues in other places, but we found this
one while doing 2.5 bringup on hardware.

	Since these branches use a special calling-convention, we don't
	want to go through the PLT stubs normally used for cross-module
	calls.  Also fix a 1-bit bug in the plt_reloc() function which
	got triggered now that the core code lives below the module
	code (due to the virtual mapping of the core).

This is an old problem, first reported in December 2001. 
The test case is a multithreaded application doing a large number of 
malloc()/free().

When running on a 16k page size kernel, the current algorithm creates
a temporary page, copies data to that page, does a new mmap and copies
back subpages from the temporary page. This leaves a window of opportunity
open for another thread to unmap or change the data in such a way that
the new page has stale data.

A patch was proposed which tries to do away with copying if the old page
was writable.  The patch was rejected because it could corrupt data in
the MAP_SHARED case.

Since we found that most of the apps which ran into this problem were
dealing with pages where the old data and new data are both anonymous,
I reworked the above patch in such a way that we don't optimize for
the MAP_SHARED case. Infact, the only case that we optimize is the case
where the old and new mapping are both anonymous.

Propagate do_settimeofday() change into osf_settimeofday().
