Gdb expects all registers windows to be flushed in ram, which is not the case in Qemu. Therefore the back-trace generation doesn't work. This patch adds a function to handle reads (and only read) in stack frames as if windows were flushed.

This patch implements MMU faults caused by TTE.NFO and TTE.E: - access other than nonfaulting load to a page marked NFO should raise data_access_exception - nonfaulting load to a page marked with E bit should raise data_access_exception To distinguish nonfaulting loads, this patch extends (abuses?) the rw argument of get_physical_address_data(). rw is set to 4 on nonfaulting loads.

This patch makes cpu_get_phys_page_debug() independent from cpu_get_phys_page_nofault() in advance of implementing nonfaulting load. This also modifies cpu_get_phys_page_nofault() to be compiled only on TARGET_SPARC64 because it is not required on SPARC32.

In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem.

handle_cpu_signal is very nearly copy-paste code for each target, with a few minor variations. This patch sets up appropriate defaults for a generic handle_cpu_signal and provides overrides for particular targets that did things differently. Fixing things like the persistent (XXX: use sigsetjmp) should now become somewhat easier. Previous comments on this patch suggest that the "activate soft MMU for this block" comments refer to defunct functionality. I have removed such blocks for the appropriate targets in this patch.
