Subject: [PATCH 1/2] malloc: use variable for ZoneHigh size
RH-Author: Paolo Bonzini <pbonzini@redhat.com>

RH-Commit: [1/2] 9e60f2104cc297ed4e78b92c5e5e11e11395bfc3
Use the variable highram_size instead of the BUILD_MAX_HIGHTABLE #define
for the ZoneHigh size. Initialize the new variable with the old #define,
so behavior does not change.
This allows to easily adjust the ZoneHigh size at runtime in a followup
patch.
