- a few time-related fixes:
- off-by-one calendar month on some classes of machines
- Y2038 preparation
- build fix for ndelay() being called with a 64-bit type
- revive 64-bit get_user(), which is used by some Android code
- defconfig updates
- fix for a long-standing fatal bug in iounmap() on '020/030, which was
actually fixed in 2.4.23, but never in 2.5.x and later
- default DMA mask to avoid warning splats
- minor fixes and cleanups
