Subject: [PATCH v3 0/5]  PCI: functions/pci-epf-test: Add DMA data transfer

Patch series uses dma engine APIs in pci-epf-test to transfer data using
DMA. It also adds an option "-d" in pcitest for the user to indicate
whether DMA has to be used for data transfer. This also prints
throughput information for data transfer.

Changes from v2:
*) Removed use of "bool" in uapi/linux/pcitest.h as that seems to fail
   for certain configs (header should be self contained). It was failing
   for "x86_64 allmodconfig".
*) Modified function comments added before DMA transfer functions.

Changes from v1:
*) Fixed some of the function names from pci_epf_* to pci_epf_test_*
since the DMA support is now been moved to pci-epf-test.c

Kishon Vijay Abraham I (5):
  PCI: endpoint: functions/pci-epf-test: Add DMA support to transfer
    data
  PCI: endpoint: functions/pci-epf-test: Print throughput information
  misc: pci_endpoint_test: Use streaming DMA APIs for buffer allocation
  tools: PCI: Add 'd' command line option to support DMA
  misc: pci_endpoint_test: Add support to get DMA option from userspace
