Impact: cleanup
Without apic=verbose, using the update_mptable option would result in
garbled and confusing output due to the inconsistent use of printk() vs
apic_printk().

Impact: fix left range size on head.
| commit 5c0e6f035df983210e4d22213aed624ced502d3d
| x86: fix code paths used by update_mptable
| Impact: fix crashes under Xen due to unrobust e820 code
fix one bug about e820 referring, but introduce other bug
need update size for left range at first in case it is header.
also add __e820_add_region take more parameter.

The change of mine here was done on purpose, since I had observed that
in this particular case (when the changed region starts later and ends earlier
than the original region) e820_add_region() would in any case create an
overlapping entry (which later gets cleaned up by sanitize_e820_map()).
That cleanup in sanitize_e820_map(), however, already implies reducing
the size of the enclosing region, and hence the original code (and the code
you try to restore now) effectively shrinks the original region twice.
Consequently, the only alternative to the code as resulting from my
patch appears to be to avoid the generation of overlapping entries in
the first place, but that would clearly make e820_update_range_map()
more complex.

Still that looks like the best course of action - the core e820
primitives should always produce a sane map.
