Speed improvements + little fixes + 0.0.2 release
- Converted condition-code + physical_get/set switch statements to jump tables - Moved the pmmu_cache lookup code out of translate_logical_addr - Broke MOVE into move-to-datareg, -from-datareg, and datareg-to-datareg - Fixed UFS code to ignore high 32 bits of inode size (it sometimes contains garbage) - Support for zero-length reads in scsi.c + 256kb read/write buffer - pushing interrupt stack frames now actually changes the priority mask - Updated the READMEs, screencaps for 0.0.2
