Hi Pali!

SPARC is special, it does not have Bnnn constants for baud rates above
2000000. Instead it defines 4 Bnnn constants with smaller baud rates.
This difference between SPARC and non-SPARC architectures is present in
both glibc API (termios.h) and also kernel ioctl API (asm/termbits.h).

Except for some wording issues (see below), looks good to me.
Thanks,
