2019-02-21physmem: keep physmem VA in 39-bit address space on x86_64Damjan Marion1-1/+1

2018-10-25pmalloc: don't lock 4K pages if we don't have access to pagemapDamjan Marion1-0/+4
Without pagemap access only way to do DMA to physmem is by using IOMMU. In such case VFIO will take care for preventing paging of such memory so we don't need to lock here. Change-Id: Ica9c20659fba3ea3c96202eb5f7d29c43b313fa9 Signed-off-by: Damjan Marion <damarion@cisco.com>
