xv6 is a re-implementation of Dennis Ritchie's and Ken Thompson's Unix
Version 6 (v6). xv6 loosely follows the structure and style of v6,
but is implemented for a modern x86-based multiprocessor using ANSI C.
xv6 is inspired by John Lions' Commentary on UNIX 6th Edition (Peer
to Peer Communications; ISBN: 1-57398-013-7; 1st edition (June 14,
2000)). See also http://pdos.csail.mit.edu/6.828/2006/v6.html, which
provides pointers to on-line resources for v6.
xv6 borrows code from the following sources:
JOS (asm.h, elf.h, mmu.h, bootasm.S, ide.c, console.c, and others)
Plan 9 (bootother.S, mp.h, mp.c, ioapic.h, lapic.c)
FreeBSD (ioapic.c)
NetBSD (console.c)

so don't be surprised if there are errors or the code is unclear.
