This is the first snapshot of the FreeBSD/ia64 kernel. This kernel will not work on any real hardware (or fully work on any simulator). Much more needs to happen before this is actually functional but its nice to see the FreeBSD copyright message appear in the ia64 simulator.

Change hw.physmem and hw.usermem to unsigned long like they used to be in the original hardwired sysctl implementation. The buf size calculator still overflows an integer on machines with large KVA (eg: ia64) where the number of pages does not fit into an int. Use 'long' there. Change Maxmem and physmem and related variables to 'long', mostly for completeness. Machines are not likely to overflow 'int' pages in the near term, but then again, 640K ought to be enough for anybody. This comes for free on 32 bit machines, so why not?

Further cleanup <machine/cpu.h> and <machine/md_var.h>: move the MI prototypes of cpu_halt(), cpu_reset() and swi_vm() from md_var.h to cpu.h. This affects db_command.c and kern_shutdown.c. ia64: move all MD prototypes from cpu.h to md_var.h. This affects madt.c, interrupt.c and mp_machdep.c. Remove is_physical_memory(). It's not used (vm_machdep.c). alpha: the MD prototypes have been left in cpu.h with a comment that they should be there. Moving them is left for later. It was expected that the impact would be significant enough to be done in a seperate commit. powerpc: MD prototypes left in cpu.h. Comment added. Suggested by: bde Tested with: make universe (pc98 incomplete)

Fix a place where I forgot to change the code that checks whether we return to kernel or userland. This triggered a panic in a KSE application when TDF_USTATCLOCK was set in the case userland was interrupted, but we never called ast() on our way out. As such, we called ast() at some other time. Unfortunately, TDF_USTATCLOCK handling assumes running in the interrupt thread. This was not the case anymore. To avoid making the same mistake later, interrupt() now returns to its caller whether we interrupted userland or not. This avoids that we have to duplicate the check in assembly, where it's bound to fall off the scope. Now we simply check the return value and call ast() if appropriate. Run into this: davidxu
