Re: [PATCH v2] powerpc/xmon: Allow limiting the size of the paca display

The paca display is already more than 24 lines, which can be problematic
if you have an old school 80x24 terminal, or more likely you are on a
virtual terminal which does not scroll for whatever reason.

We'd like to expand the paca display even more, so add a way to limit
the number of lines that are displayed.

This adds a third form of 'dp' which is 'dp # #', where the first number
is the cpu, and the second is the number of lines to display.

Example output:

  5:mon> dp 3 6
  paca for cpu 0x3 @ c00000000fe00c00:
   possible         = yes
   present          = yes
   online           = yes
   lock_token       = 0x8000            	(0xa)
   paca_index       = 0x3               	(0x8)

Michael,

This patch inspired me to do the additional work to make the output paged, more
like the memory dump commands.

I'll post it shortly as "powerpc/xmon: Paged output for paca display".

Cheers,
Sam.
