d844f0f9d9 Change dev read/write functions
to take inode* instead of minor number.

Unlock console inode during console_read
and console_write.  Otherwise background
processes cannot write to console while the
shell is reading it waiting for input.

8970df0c1b No one is going to find this inode.
There is only one ref to it -- the caller --
and no links to it.

b63bb0fd00 Clean up lapic code.
One initialization function now, not three.
Use #defines instead of enums (consistent with other code, but sigh).

Still boots in Bochs in SMP mode.

629c1fe743 Edit exec.
Do not commit to new memory image until
nothing can go wrong, avoiding bad2 case.

Be sure to allocate enough stack space for argv.

Load executable before initializing stack, to
keep ELF loops together.

Make argv loop clearer.

d003d232fc Another attempt at the bio.c comment.
Rename B_WRITE to B_DIRTY and then let ide.c
maintain the B_VALID and B_DIRTY flags.
