[Qemu-devel] [PATCH 04/22] spapr: Remove obsolete ram_limit field from sPAPRMachineState |
Date: |
Wed, 24 Jun 2015 16:30:18 +1000 |
The ram_limit field was imported from sPAPREnvironment where it predates
the machine's ram size being available generically from machine->ram_size.
Worse, the existing code was inconsistent about where it got the ram size
from. Sometimes it used spapr->ram_limit, sometimes the global 'ram_size'
and sometimes a local 'ram_size' masking the global.
This cleans up the code to consistently use machine->ram_size, eliminating
spapr->ram_limit in the process.
