* Restructure the way the copyin/copyout segment is stored to prevent aNathan Whitehorn2010-10-3012-41/+60
| | | | | | | | | | | | | | | | | | | | concurrency bug. Since all SLB/SR entries were invalidated during an exception, a decrementer exception could cause the user segment to be invalidated during a copyin()/copyout() without a thread switch that would cause it to be restored from the PCB, potentially causing the operation to continue on invalid memory. This is now handled by explicit restoration of segment 12 from the PCB on 32-bit systems and a check in the Data Segment Exception handler on 64-bit. While here, cause copyin()/copyout() to check whether the requested user segment is already installed, saving some pipeline flushes, and fix the synchronization primitives around the mtsr and slbmte instructions to prevent accessing stale segments.

| | | | | | | | | | | | | | | | | | | | | | | | | | the dual port BCM5717 and BCM5718 devices which are intended for mainstream workstation and entry-level server designs and represents the twelfth generation of NetXtreme Ethernet controllers. This family is the successor to the BCM5714/BCM5715 family and supports IPv4/IPv6 checksum offloading, TSO, VLAN hardware tagging, jumbo frames, MSI/MSIX, IOV, RSS and TSS. This change set supports all hardware features except IOV and RSS/TSS. Unlike its predecessors, only extended RX buffer descriptors can be posted to the jumbo producer ring. Single RX buffer descriptors for jumbo frame are not supported. RSS requires a more substantial set of changes and will apply to a larger set of NetXtreme devices so RSS/TSS multi-queue support will be implemented in a future releases.

| | | | | | | | | | | | | | | | delegations are being returned for reasons other than a Recall. Also, re-organize nfscl_recalldeleg() slightly, so that it leaves clearing NMODIFIED to the ncl_flush() call and invalidates the attribute cache after flushing. It is hoped that these changes might fix the problem others have seen when using the NFSv4 client with delegations enabled, since I can't reliably reproduce the problem. These changes only affect the client when doing NFSv4 mounts with delegations enabled. MFC after: 10 days Notes: svn path=/head/; revision=214406

| | | | | | | | | | | | | | | | | | | | | | 'hw.acpi.remove_interface'. hw.acpi.install_interface lets you install new interfaces. Conversely, hw.acpi.remove_interface lets you remove OS interfaces from the pre-defined list in ACPICA. For example, hw.acpi.install_interface="FreeBSD" lets _OSI("FreeBSD") method to return 0xffffffff (or success) and hw.acpi.remove_interface="Windows 2009" lets _OSI("Windows 2009") method to return zero (or failure). Both are comma-separated lists and leading white spaces are ignored. For example, the following examples are valid: hw.acpi.install_interface="Linux, FreeBSD" hw.acpi.remove_interface="Windows 2006, Windows 2006.1" Notes: svn path=/head/; revision=214390
