[PATCH v2 1/7] vmw_balloon: fix inflation of 64-bit GFNs

2018-06-13 Thread Nadav Amit
When balloon batching is not supported by the hypervisor, the guest frame number (GFN) must fit in 32-bit. However, due to a bug, this check was mistakenly ignored. In practice, when total RAM is greater than 16TB, the balloon does not work currently, making this bug unlikely to happen. Fixes:
