432f5e3ab9 Disable interrupts for atomic_cmpset_32, this one is just not atomic.
Don't export it to userland.

bd366a3cd4 Copy the syscall args in a tmp variable instead of directly using the
trapframe, as it can be modified in the syscall.
Call thread_user_enter() when appropriate.

90f794aaaf If we're still running at the physical address, jump to the virtual address
instead before calling initarm().
This removes the need to map virtual == physical in initarm().

d39d4a6e64 - Change the ddb paging "support" to use a variable (db_lines_per_page) to
control the number of lines per page rather than a constant.  The variable
  can be examined and changed in ddb as '$lines'.  Setting the variable to
  0 will effectively turn off paging.
- Change db_putchar() to force out pending whitespace before outputting
  newlines and carriage returns so that one can rub out content on the
  current line via '\r     \r' type strings.
- Change the simple pager to rub out the --More-- prompt explicitly when
  the routine exits.
- Add some aliases to the simple pager to make it more compatible with
  more(1): 'e' and 'j' do a single line.  'd' does half a page, and
  'f' does a full page.

6052fa47a9 Import partial support for the IQ31244 eval board (i80321 CPU). IQ80321 might
work out of the box too, but I have no hardware to test.
It works well enough to go multiuser. Network works, SATA does not, as I have
no drive to test.
Thanks to Intel for sending such a board.
