This patchset: PV guests under Xen are running in an non-contiguous memory architecture. When PCI pass-through is utilized, this necessitates an IOMMU for translating bus (DMA) to virtual and vice-versa and also providing a mechanism to have contiguous pages for device drivers operations (say DMA operations). Specifically, under Xen the Linux idea of pages is an illusion. It assumes that pages start at zero and go up to the available memory. To help with that, the Linux Xen MMU provides a lookup mechanism to translate the page frame numbers (PFN) to machine frame numbers (MFN) and vice-versa. The MFN are the "real" frame numbers. Furthermore memory is not contiguous. Xen hypervisor stitches memory for guests from different pools, which means there is no guarantee that PFN==MFN and PFN+1==MFN+1. Lastly with Xen 4.0, pages (in debug mode) are allocated in descending order (high to low), meaning the guest might never get any MFN's under the 4GB mark.

That default MTU is calculated from the size of two DH5 packets, minus ACL and L2CAP b-frame header overhead. ERTM is used with newer basebands that typically support larger 3-DH5 packets, and i-frames and s-frames have more header overhead. With clean RF conditions, basebands will typically attempt to use 1021-byte 3-DH5 packets for maximum throughput. Adjusting for 2 bytes of ACL headers plus 10 bytes of worst-case L2CAP headers yields 1009 bytes of payload. This PDU size imposes less overhead for header bytes and gives the baseband the option to choose 3-DH5 packets, but is small enough for ERTM traffic to interleave well with other L2CAP or SCO data. 672-byte payloads do not allow the most efficient over-the-air packet choice, and cannot achieve maximum throughput over BR/EDR.

While hugepage is not currently swappable, reverse mapping can be useful for memory error handler. Without this patch, memory error handler cannot identify processes using the bad hugepage nor unmap it from them. That is: - for shared hugepage: we can collect processes using a hugepage through pagecache, but can not unmap the hugepage because of the lack of mapcount. - for privately mapped hugepage: we can neither collect processes nor unmap the hugepage. This patch solves these problems. This patch include the bug fix given by commit 23be7468e8, so reverts it.
