2018-11-10pmalloc: u32 pp->index leads to va address overrunKingwel Xie1-1/+2
when pagesize is 1G, this pm->base + (pp->index << pm->def_log2_page_sz) would very soon overrun if creating multiple mempools add a (uword) to it Change-Id: If769b99d344cc3f547418a242a7497d044071615 Signed-off-by: Kingwel Xie <kingwel.xie@ericsson.com>

2018-10-25pmalloc: don't lock 4K pages if we don't have access to pagemapDamjan Marion1-6/+26
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>
