The commit 139ddfcab50e5eabcc88341c8743a990ac1be6a2 ("ide: move handling of I/O resources out of ide_probe_port()") changed the ordering of hwif->noprobe check vs ide_hwif_request_regions() call (so that we now reserve I/O regions before checking for hwif->noprobe). However ide-generic host driver depended on hwif->noprobe to be set for skipping probing of empty ide_hwifs[] slots. Fix it by passing only indexes of non-empty slots to ide_device_add_all() from ide_generic_init(). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

This makes sure that the struct work is always initialized before it is used.

| * [S390] dasd: fix panic caused by alias device offlineStefan Weinhuber2008-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When an alias device is set offline while it is in use this may result in a panic in the cleanup part of the dasd_block_tasklet. The problem here is that there may exist some ccw requests that were originally created for the alias device and transferred to the base device when the alias was set offline. When these request are cleaned up later, the discipline pointer in the alias device may not be valid anymore. To fix this use the base device discipline to find the cleanup function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases the current sense id procedure trips over incomplete hardware responses. In these cases, checking against the preset value of 0xFFFF is not enough. More critically, the VM DIAG call will always be considered to have provided data after such an incident, even if it was not successful at all. The solution is to always initialize the control unit data before doing a sense id call. Check the condition code before considering the control unit data. And initialize again, before evaluating the VM data. Signed-off-by: Peter Oberparleiter <peter.oberparleiter@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

Note that tun_set_iff contains 541 if (ifr->ifr_flags & IFF_NO_PI) 542 tun->flags |= TUN_NO_PI; 543 544 if (ifr->ifr_flags & IFF_ONE_QUEUE) 545 tun->flags |= TUN_ONE_QUEUE; This is easily fixed by adding else branches which clear these bits. Steps to reproduce: This is easily reproduced by setting an interface persistant using tunctl then attempting to open it as IFF_TAP or IFF_TUN, without asserting the IFF_NO_PI flag. The ioctl() will succeed and the ifr.flags word is not modified, but the interface remains in IFF_NO_PI mode (as it was set by tunctl).

| | | | | | | | | | | | | | | | | | | | | | | | This is a bit of a large hammer but it makes sure the chipset is flushed by writing out 1k of data to an uncached page. We may be able to get better information in the future on how to this better. Signed-off-by: Dave Airlie <airlied@redhat.com>
| * | intel-agp: add chipset flushing supportDave Airlie2008-02-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for flushing the chipsets on the 915, 945, 965 and G33 families of Intel chips. The BIOS doesn't seem to always allocate the BAR on the 965 chipsets so I have to use pci resource code to create a resource It adds an export for pcibios_align_resource.
| * | agp: add chipset flushing support to AGP interfaceDave Airlie2008-02-04
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | This bumps the AGP interface to 0.103. Certain Intel chipsets contains a global write buffer, and this can require flushing from the drm or X.org to make sure all data has hit RAM before initiating a GPU transfer, due to a lack of coherency with the integrated graphics device and this buffer. This just adds generic support to the AGP interfaces, a follow-on patch will add support to the Intel driver to use this interface. Signed-off-by: Dave Airlie <airlied@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a host just goes away (crash, power loss, etc.) without tearing down its IB connections, it can get stale connection errors when it tries to reconnect to targets upon rebooting. Retrying the connection a few times will prevent sysadmins from playing the "which disk(s) went missing?" game. This would have made things slightly quicker when tracking down some of the recent bugs, but it also helps quite a bit when you've got a large number of targets hanging off a wedged server.
