We don't use lesp/lebp and using them at all from C would be fraught with peril. Keep resp/rebp, but fix their code style.
Page breaking of mmu.h
Start PDE defs on new page
Follow xv6 code style. Also fixes indexing for these functions
Rearrange for better page breaking
Fix too-long lines
Rebalance TOC
Acknowledge patches
Hopefully get the printf size spec right, regardless of compiler.
no more pminit, or ELF header at 0x10000
mkfs must be compiled 32-bit. Fix mkfs warnings
Infer qemu path, just like in JOS
Infer TOOLPREFIX, just like in JOS
Merge branch 'page' of git+ssh://amsterdam.csail.mit.edu/home/am0/6.828/xv6 into page
kalloc/kfree now only a page at a time

Merge remote branch 'origin/master' into page
Fix for gdbstub argument change in qemu 0.11. Rename qemu-gdb-nox target to qemu-nox-gdb because you frequently want to add the gdb part, but rarely the nox part.
oops ended up with 2x vm.c
Merge remote branch 'origin/page' into page
xx
no more xv6.pdf .ps
we don't need CR0_WP
set only PG and WP in vminit; the rest don't seem to be needed and are confusing

uptime() sys call for benchmarking
allow sbrk(-x) to de-allocate user memory
fix corner cases in exec of ELF
add some comments
remove some unused vm #defines
move jkstack to main.c

kill TLB shoot down code
more cleanup
some cleanup
a few nits
oops, vm.c
