Renumber I_VALID since I_BUSY is gone
dir-locals.el to set style in Emacs
Style nits; indentation and tabs
Merge branch 'master' of git+ssh://amsterdam.csail.mit.edu/home/am0/6.828/xv6
Introduce and use sleeplocks instead of BUSY flags
segment register -> segment descriptor
Make cross reference with text work
Eliminate USERTOP; no use for it.
A comment
Remove sys_init syscall
Merge branch 'master' of git+ssh://amsterdam.csail.mit.edu/home/am0/6.828/xv6
delete dead code
make dirlookup and dirlink more similar
bootloader reads into a physical address (not a virtual address)
Make elf proghdr fields match what objdump prints
Switch back to #define for PHYSTOP. Using the E820 to retrieve the memory map is too complicated (must be done in 16-bit real-mode, probably enlarged bootblock beyond 512 bytes, and a #define requires less explanation).
Clean up memlayout.h
Update make clean
Update list of files to include in printout
Make Austin happier
Avoid "boot" in xv6
Use 4Mbyte pages during boot
Only commit log to disk if something was written in to it.
Merge branch 'master' of git+ssh://amsterdam.csail.mit.edu/home/am0/6.828/xv6
avoid deadlock by calling begin_trans() before locking any inodes
Separate more clearly bootloader from xv6 by renaming multiboot.S to entry.S etc.
Oops
Merge branch 'master' of git+ssh://amsterdam.csail.mit.edu/home/am0/6.828/xv6
log write() data
Some comments
Make AP processors boot using bootpgdir
One more low address
Tiny bit of cleanup
Shorten boot assembly
x
Remove jmpkstack
Use static page table for boot, mapping first 4Mbyte; no more segment trick
Use kernel virtual addresses for BIOS memory, etc.
Allow gas to use / as divide (instead of comment)
One definition of several macros and constants
