4c2a93ea02 Fix munmap(2) shrink from right logic. 
This fixes a rather nasty issue where gcc's garbage collection triggered a
munmap call with the effect that it began unmapping huge amounts of kernel
data until the system triple faulted.

6725972e11 Fix LinkInodeInDir return value. 
The callers expected it to return an int different than 0 on failure. The
link method returns different than 0 on failure. This actually worked by
lucky coincidence. Change the return type to int and 0 on success, and -1
on failure per popular demand.

Thanks to Meisaka Yukara for spotting this.
