| * x86/PCI: compute Address Space length rather than using _LENBjorn Helgaas2010-04-281-38/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ACPI _CRS Address Space Descriptors have _MIN, _MAX, and _LEN. Linux has been computing Address Spaces as [_MIN to _MIN + _LEN - 1]. Based on the tests in the bug reports below, Windows apparently uses [_MIN to _MAX]. Per spec (ACPI 4.0, Table 6-40), for _CRS fixed-size, fixed location descriptors, "_LEN must be (_MAX - _MIN + 1)", and when that's true, it doesn't matter which way we compute the end. But of course, there are BIOSes that don't follow this rule, and we're better off if Linux handles those exceptions the same way as Windows. This patch makes Linux use [_MIN to _MAX], as Windows seems to do. This effectively reverts d558b483d5 and 03db42adfe and replaces them with simpler code. https://bugzilla.kernel.org/show_bug.cgi?id=14337 (round) https://bugzilla.kernel.org/show_bug.cgi?id=15480 (truncate) Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
| * x86/PCI: never allocate PCI MMIO resources below BIOS_ENDBjorn Helgaas2010-04-261-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When we move a PCI device or assign resources to a device not configured by the BIOS, we want to avoid the BIOS region below 1MB. Note that if the BIOS places devices below 1MB, we leave them there.

* | nfs d_revalidate() is too trigger-happy with d_drop()Al Viro2010-04-281-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If dentry found stale happens to be a root of disconnected tree, we can't d_drop() it; its d_hash is actually part of s_anon and d_drop() would simply hide it from shrink_dcache_for_umount(), leading to all sorts of fun, including busy inodes on umount and oopsen after that. Bug had been there since at least 2006 (commit c636eb already has it), so it's definitely -stable fodder.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Re-submitted based on comments from netdev community. Summary of the changes: 1. Improved error handling. 2. Added the missing timeout arguments to usb_control_msg(). The following is a new Linux driver which exposes certain models of Sierra Wireless modems to the operating system as Network Interface Cards (NICs). This driver requires a version of the sierra.c driver which supports blacklisting to work properly. The blacklist in sierra.c rejects the interfaces claimed by sierra_net.c. Likewise, the sierra_net.c driver only accepts (i.e. whitelists) the interface(s) used for USB-to-WWAN traffic. The version of sierra.c which supports blacklisting is available from the sierra wireless knowledge base page for older kernels. It is also available in Linux kernel starting from version 2.6.31. This driver works with all Sierra Wireless devices configured with PID=68A3 like USB305, USB306 provided the corresponding firmware version is I2.0 (for USB305) or M3.0 (for USB306) and later. This driver will not work with earlier firmware versions than the ones shown above. In this case the driver will issue an error message indicating incompatibility and will not serve the device's USB-to-WWAN interface. Sierra_net.c sits atop a pre-existing Linux driver called usbnet.c. A series of hook functions are provided in sierra_net.c which are called by usbnet.c in response to a particular condition such as receipt or transmission of a data packet. As such, usbnet.c does most of the work of making a modem appear to the system as a network device and for properly exchanging traffic between the USB subsystem and the Network card interface. Sierra_net.c is concerned with managing the data exchanged between the USB-to-WWAN interface and the upper layers of the operating system.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bonding driver calls ndo_vlan_rx_register() while holding bond->lock. The bnx2 driver calls bnx2_netif_stop() to stop the rx handling while changing the vlgrp. The call also stops the cnic driver which sleeps while the bond->lock is held and cause the warning. This code path only needs to stop the NAPI rx handling while we are changing the vlgrp. Since no reset is going to occur, there is no need to stop cnic in this case. By adding a parameter to bnx2_netif_stop() to skip stopping cnic, we can avoid the warning. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It has been reported that under certain heavy traffic conditions in MSI-X mode, the driver can lose an MSI-X vector causing all packets in the associated rx/tx ring pair to be dropped. The problem is caused by the chip dropping the write to unmask the MSI-X vector by the kernel (when migrating the IRQ for example). This can be prevented by increasing the GRC timeout value for these register read and write operations. Thanks to Dell for helping us debug this problem.

For standard frames, 82573/82574/82583 can enable L1 but L0s must be disabled, and for jumbo frames 82573/82574 must disable L1. This allows for some parts to enable L1 in certain configurations leading to better power savings. Also according to the same errata, Early Receive (ERT) should be disabled on 82573 when using jumbo frames.
