Size restrictions native kernels wouldn't have resulted from the initrd getting mapped into the initial mapping. The kernel doesn't really need the initrd to be mapped, so use infrastructure available in Xen to avoid the mapping and hence the restriction.

To be able to use an initially unmapped initrd with xen the following header files must be synced to a newer version from the xen tree: include/xen/interface/elfnote.h include/xen/interface/xen.h As the KEXEC and DUMPCORE related ELFNOTES are not relevant for the kernel they are omitted from elfnote.h.

The _PAGE_IO_MAP PTE flag was only used by Xen PV guests to mark PTEs that were used to map I/O regions that are 1:1 in the p2m. This allowed Xen to obtain the correct PFN when converting the MFNs read from a PTE back to their PFN. Xen guests no longer use _PAGE_IOMAP for this. Instead mfn_to_pfn() returns the correct PFN by using a combination of the m2p and p2m to determine if an MFN corresponds to a 1:1 mapping in the the p2m. Remove _PAGE_IOMAP, replacing it with _PAGE_UNUSED2 to allow for future uses of the PTE flag. Signed-off-by: David Vrabel <david.vrabel@citrix.com> Acked-by: "H. Peter Anvin" <hpa@zytor.com>

Since mfn_to_pfn() returns the correct PFN for identity mappings (as used for MMIO regions), the use of _PAGE_IOMAP is not required in pte_mfn_to_pfn(). Do not set the _PAGE_IOMAP flag in pte_pfn_to_mfn() and do not use it in pte_mfn_to_pfn(). This will allow _PAGE_IOMAP to be removed, making it available for future use.

If a fault on a kernel address is due to a non-present page, then it cannot be the result of stale TLB entry from a protection change (RO to RW or NX to X). Thus the pagetable walk in spurious_fault() can be skipped. See the initial if in spurious_fault() and the tests in spurious_fault_check()) for the set of possible error codes checked for spurious faults. These are: IRUWP Before x00xx && ( 1xxxx || xxx1x ) After ( 10001 || 00011 ) && ( 1xxxx || xxx1x ) Thus the new condition is a subset of the previous one, excluding only non-present faults (I == 1 and W == 1 are mutually exclusive). This avoids spurious_fault() oopsing in some cases if the pagetables it attempts to walk are not accessible. This obscures the location of the original fault. This also fixes a crash with Xen PV guests when they access entries in the M2P corresponding to device MMIO regions. The M2P is mapped (read-only) by Xen into the kernel address space of the guest and this mapping may contains holes for non-RAM regions. Read faults will result in calls to spurious_fault(), but because the page tables for the M2P mappings are not accessible by the guest the pagetable walk would fault. This was not normally a problem as MMIO mappings would not normally result in a M2P lookup because of the use of the _PAGE_IOMAP bit the PTE. However, removing the _PAGE_IOMAP bit requires M2P lookups for MMIO mappings as well.

Introduces the Xen pvSCSI backend. With pvSCSI it is possible for a Xen domU to issue SCSI commands to a SCSI LUN assigned to that domU. The SCSI commands are passed to the pvSCSI backend in a driver domain (usually Dom0) which is owner of the physical device. This allows e.g. to use SCSI tape drives in a Xen domU. The code is taken from the pvSCSI implementation in Xen done by Fujitsu based on Linux kernel 2.6.18. Changes from the original version are: - port to upstream kernel - put all code in just one source file - adapt to Linux style guide - use target core infrastructure instead doing pure pass-through - enable module unloading - support SG-list in grant page(s) - support task abort - remove redundant struct backend - allocate resources dynamically - correct minor error in scsiback_fast_flush_area - free allocated resources in case of error during I/O preparation - remove CDB emulation, now handled by target core infrastructure Signed-off-by: Juergen Gross <jgross@suse.com> Reviewed-by: Nicholas Bellinger <nab@linux-iscsi.org> Signed-off-by: David Vrabel <david.vrabel@citrix.com>

Instead of ballooning up and down dom0 memory this remaps the existing mfns that were replaced by the identity map. The reason for this is that the existing implementation ballooned memory up and and down which caused dom0 to have discontiguous pages. In some cases this resulted in the use of bounce buffers which reduced network I/O performance significantly. This change will honor the existing order of the pages with the exception of some boundary conditions. To do this we need to update both the Linux p2m table and the Xen m2p table. Particular care must be taken when updating the p2m table since it's important to limit table memory consumption and reuse the existing leaf pages which get freed when an entire leaf page is set to the identity map. To implement this, mapping updates are grouped into blocks with table entries getting cached temporarily and then released. On my test system before: Total pages: 2105014 Total contiguous: 1640635 After: Total pages: 2105014 Total contiguous: 2098904 Signed-off-by: Matthew Rushton <mrushton@amazon.com> Signed-off-by: David Vrabel <david.vrabel@citrix.com>

This patch adds quirks for Entrega Technologies (later Xircom PortGear) USB- SCSI converters. They use Shuttle Technology EUSB-01/EUSB-S1 chips. The US_FL_SCM_MULT_TARG quirk is needed to allow multiple devices on the SCSI chain to be accessed. Without it only the (single) device with SCSI ID 0 can be used. The standalone converter sold by Entrega had model number U1-SC25. Xircom acquired Entrega and re-branded the product line PortGear. The PortGear USB to SCSI Converter (model PGSCSI) is internally identical to the Entrega product, but later models may use a different USB ID. The Entrega-branded units have USB ID 1645:0007, as does my Xircom PGSCSI, but the Windows and Macintosh drivers also support 085A:0028. Entrega also sold the "Mac USB Dock", which provides two USB ports, a Mac (8-pin mini-DIN) serial port and a SCSI port. It appears to the computer as a four-port hub, USB-serial, and USB-SCSI converters. The USB-SCSI part may have initially used the same ID as the standalone U1-SC25 (1645:0007), but later production used 085A:0026. My Xircom PortGear PGSCSI has bcdDevice=0x0100. Units with bcdDevice=0x0133 probably also exist. This patch adds quirks for 1645:0007, 085A:0026 and 085A:0028. The Windows driver INF file also mentions 085A:0032 "PortStation SCSI Module", but I couldn't find any mention of that actually existing in the wild; perhaps it was cancelled before release?

Hi, The Ariston Technologies iConnect 025 and iConnect 050 (also known as e.g. iSCSI-50) are SCSI-USB converters which use Shuttle Technology/SCM Microsystems chips. Only the connectors differ; both have the same USB ID. The US_FL_SCM_MULT_TARG quirk is required to use SCSI devices with ID other than 0. I don't have one of these, but based on the other entries for Shuttle/ SCM-based converters this patch is very likely correct. I used 0x0000 and 0x9999 for bcdDeviceMin and bcdDeviceMax because I'm not sure which bcdDevice value the products use.

Old code in ehci-hcd tries to expedite disabling endpoints after the controller has stopped, by destroying the endpoint's associated QH without first unlinking the QH. This was necessary back when the driver wasn't so careful about keeping track of the controller's state. But now we are careful about it, and the driver knows that when the controller isn't running, no unlinking delay is needed. Furthermore, skipping the unlink step will trigger a BUG() in qh_destroy() when the preceding QH is released, because the link pointer will be non-NULL. Removing the lines that skip the unlinking step and go directly to QH_STATE_IDLE fixes the problem.
