1995-11-10fix DVMA problem on sun4 systems with writeback cache. you needchuck
to flush the cache after map in so that the info gets written into main memory. you really only need to do this when writing data (e.g. disk write), but there is currently no way to tell if you are writing so we do it for all cases (XXX this is stupid, fix later). This causes 4/200's to be able to write disk files on SMD disks without data corruption.

1995-11-07optimized in_cksum from Zubin Dittia <zubin@dworkin.wustl.edu>chuck
Zubin says: The checksum computation code here is significantly faster than its vanilla C counterpart (by significantly, I mean 2-3 times faster if the data is in cache, and 1.5-2 times faster if the data is not in cache). We optimize on three fronts: 1. By using the add-with-carry (addxcc) instruction, we can use 32-bit operations instead of 16-bit operations. 2. By unrolling the main loop to reduce branch overheads. 3. By doing a sequence of load,load,add,add,load,load,add,add, we can avoid the extra stall cycle which is incurred if the instruction immediately following a load tries to use the target register of the load. Another possible optimization is to replace a pair of 32-bit loads with a single 64-bit load (ldd) instruction, but I found that although this improves performance somewhat on Sun4c machines, it actually reduces performance considerably on Sun4m machines (because of their superscaler architecture). So I chose to leave it out.
1995-11-07fix type-o by pk. a sun4 cpumodel looks like "SUN-4" rather thanchuck
"SUN/4" ... sun4's definitely do *not* want the a.out header installed.
