3b5501efa7 Cleanup last by using a "n"umeric address space identifier.

a63279589c When invalidating a context, make sure to flush user windows upfront. 
Do not set the DMMU secondary context to 0 (that would be kernel), and
add a few required membars after switching the secondary dmmu context.

This avoids SIRs caused by double kernel_data_faults, caused by spills
of obsolete user windows after the context for that user pmap is gone.

fbae48b901 Change "inline" back to "__inline" in .h files -- C99 is still too 
new, and some apps compile things in C89 mode. C89 keywords stay.

As per core@.

d50f0c6274 ANSIfication: u_intN_t -> uintN_t, use ANSI function declarations/definitions 
instead of K&R ones.

a021a66c36 Added UPA_MID definitions and macros(similar to FreeBSD). 
Added membar_store, membar_load macros.
No need to set %asi _after_ alternate space use in corresponding functions.
Enable(unifdef) casa functions for __arch64__.

3143adecfb Tell gcc that stores clobber "memory". Probably makes no difference since 
they should not be used to access normal memory anyway.

85cab8fe27 More VM cleanup: 
Move the cpu_info structure above the interrupt stack so it won't
	get corrupted if the stack overflows.

	Flush the D$ before and after all MMU bypass accesses since the
	D$ latches all of those.

186c3eba2b Make pbrobeget() and probeset() work for 64-bit values as well. To do this 
the arguments are changed so the address is first and the ASI second so we
can have the address in %o0:%o1 and not worry about unused registers.

Also a bit of copyright cleanup.
