Changes since 1.1: +20 -11 lines

Rename "stack" to "stacktrace" and have "stack" call "stacktrace $ebp $eip"
(saves typing).

Use sizeof(long) instead of "4".

# Follow an i386 kernel stack trace.
# This code makes presumptions about the way frames look, consistent
# with arch/i386/i386/db_trace.c. It also steals algorithms from there.

# Output looks like:
#
#  0xc03049cb <cpu_reboot+99>(0x100,0x0,0xc04fd728,0x0,0x6)
#	      at 0xc01bc97d <panic+197> (frame at 0xc5633bd0)
#
# In this case, the initial hex number and offset should be disregarded,
# and it should be interprted as if it were:
#
#  cpu_reboot(0x100,0x0,0xc04fd728,0x0,0x6)
#	      at 0xc01bc97d <panic+197> (frame at 0xc5633bd0)
#
# due to limitations of gdb scripting.

document stacktrace
  ==> (gdb) stacktrace FP IP
  print a backtrace of all stack frames, starting at frame pointer FP,
  and instruction pointer IP.

document stack
  => (gdb) stack
  Print a backtrace of all strack frames, starting at the current $ebp
  and $eip.
