[PATCH 16/50] x86/boot/e820: Harmonize the 'struct e820_table' fields

From: Ingo Molnar
Date: Sat Jan 28 2017 - 17:20:05 EST

So the e820_table->map and e820_table->nr_map names are a bit
confusing, because it's not clear what a 'map' really means
(it could be a bitmap, or some other data structure), nor is
it clear what nr_map means (is it a current index, or some
other count).

Rename the fields from:

e820_table->map => e820_table->entries
e820_table->nr_map => e820_table->nr_entries

which makes it abundantly clear that these are entries
of the table, and that the size of the table is ->nr_entries.

Propagate the changes to all affected files. Where necessary,
adjust local variable names to better reflect the new field names.

No change in functionality.
