For some subplatforms the default, pre-allocated pool for atomic allocations turned out to be too small, so a function for setting its size has been added.

The underlaying reason is that if the supplied driver passes in a DMA_BIT_MASK(64) ( hwdev->coherent_dma_mask is set to 0xffffffffffffffff) our dma_mask will be u64 set to 0xffffffffffffffff even if we set it to DMA_BIT_MASK(32) previously. Meaning we do not reset the upper bits. By using the dma_alloc_coherent_mask function - it does the proper casting and we get 0xfffffffff. This caused not working sound on a system with 4 GB and a 64-bit compatible sound-card with sets the DMA-mask to 64bit. On bare-metal and the forward-ported xen-dom0 patches from OpenSuse a coherent DMA-memory is always allocated inside the 32-bit address-range by calling dma_alloc_coherent_mask. This patch adds the same functionality to xen swiotlb and is a rebase of the original patch from Ronny Hegewald which never got upstream b/c the underlaying reason was not understood until now.

That may give a incorrect op.cmd to MMUEXT_INVLPG_MULTI instead of MMUEXT_TLB_FLUSH_MULTI. Then it causes some page can not be flushed from TLB. This patch fixed this issue.

This is because the device configuration space registers will be not accessible if the corresponding parent bridge is suspended or the device is put into D3cold state. To solve the issue, the bridge/PCIe port connected to the device is put into active state before read/write configuration space registers. If the device is in D3cold state, it will be put into active state too. To avoid resume/suspend PCIe port for each configuration register read/write, a small delay is added before the PCIe port to go suspended.

If a device is not bound with the corresponding driver, the device runtime PM will be disabled and the device will be put into suspended state. So that, the bridge/PCIe port connected to it may be put into suspended and low power state. When do probing for the device later, because the bridge/PCIe port connected to it is in low power state, the IO access to device may fail.

After that, D3 is further divided into D3hot and D3cold. To support both scenario safely, original D3 is mapped to D3cold. When adding D3cold support, because worry about some device may have broken D3cold support, D3cold is disabled by default. This disable D3 on original platform too. But some original platform may only have working D3, but no working D1, D2. The root cause of the above bug is it too. To deal with this, this patch enables D3/D3cold by default for most devices. This restores the original behavior. For some devices that suspected to have broken D3cold support, such as PCIe port, D3cold is disabled by default.
