In the process of rewriting the x86 setup code, I found a number of
inaccuracies and outdated recommendations in the boot protocol
documentation.  Revamp to make it more up to date.

In particular, the common use of the heap actually requires (slightly)
more than 4K of heap plus stack, which is the recommended amount in
the document; currently the code compensates by being smaller than
specified, but we can't assume that will be true forever.  Thus,
recommend that if we have a modern bzImage kernel, that the bootloader
maximizes the available space.

revert 'sched: redundant reschedule when set_user_nice() boosts a prio of a task from the "expired" array'

Revert commit bd53f96c.

Con says:

This is no good, sorry. The one I saw originally was with the staircase
deadline cpu scheduler in situ and was different.

  #define TASK_PREEMPTS_CURR(p, rq) \
     ((p)->prio < (rq)->curr->prio)
     (((p)->prio < (rq)->curr->prio) && ((p)->array == (rq)->active))

This will fail to wake up a runqueue for a task that has been migrated to the
expired array of a runqueue which is otherwise idle which can happen with smp
balancing,

This reverts commit 464bdd33.

Peter Anvin correctly points out that VESA modes have nothing to do with
frame buffers per se - they are often just regular extended text modes.
Disabling them just because we don't have frame buffer support is very
wrong.

The idea is to move more and more things into the pbm,
with the eventual goal of eliminating the pci_controller_info
entirely as there really isn't any need for it.

This stage of the transformations requires some reworking of
the PCI error interrupt handling.

It might be tricky to get rid of the pci_controller_info parenting for
a few reasons:

1) When we get an uncorrectable or correctable error we want
   to interrogate the IOMMU and streaming cache of both
   PBMs for error status.  These errors come from the UPA
   front-end which is shared between the two PBM PCI bus
   segments.

   Historically speaking this is why I choose the datastructure
   hierarchy of pci_controller_info-->pci_pbm_info

2) The probing does a portid/devhandle match to look for the
   'other' pbm, but this is entirely an artifact and can be
   eliminated trivially.

What we could do to solve #1 is to have a "buddy" pointer from one pbm
to another.
