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.
