2009-10-01Revert "Get rid of _t suffix"Anthony Liguori
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. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

2009-09-12Fix sys-queue.h conflict for goodBlue Swirl
Problem: Our file sys-queue.h is a copy of the BSD file, but there are some additions and it's not entirely compatible. Because of that, there have been conflicts with system headers on BSD systems. Some hacks have been introduced in the commits 15cc9235840a22c289edbe064a9b3c19c5f49896, f40d753718c72693c5f520f0d9899f6e50395e94, 96555a96d724016e13190b28cffa3bc929ac60dc and 3990d09adf4463eca200ad964cc55643c33feb50 but the fixes were fragile. Solution: Avoid the conflict entirely by renaming the functions and the file. Revert the previous hacks. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2009-09-11microblaze: Correct prio between MMU and unaligned exceptions.Edgar E. Iglesias
The microblaze gives MMU faults priority. For stores we still have a flaw that the value leaks to memory in the case of an unaligned exception. Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>

2009-08-24cleanup cpu-exec.c, part 0/N: consolidate handle_cpu_signalNathan Froyd
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.
