| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | For some vendor/id pairs the kernel will autoload both the sis-agp and the amd64_agp modules as the sis-agp module will load for all sis devices. This collision causes the bug reported in: http://bugzilla.novell.com/show_bug.cgi?id=248665 As currently sis_probe does its own matching, requesting the whole range gains nothing. The clean fix seems to me to leave the matching to the core and advertise only the devices actually supported. This patch does so.

* | libata: honour host controllers that want just one hostLinus Torvalds2007-04-301-7/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Marvell IDE interface on my machine would hit a BUG_ON() in lib/iomem.c because it was calling ata_pci_init_one() specifying just a single port on the host, but that would actually end up trying to initialize two ports, the second one with bogus information. This fixes "ata_pci_init_one()" so that it actually passes down the n_ports variable that it got from the low-level driver to the host allocation routine ("ata_host_alloc_pinfo()"), which results in the ATA layer actually having the correct port number information. And in order to make it all work, I also needed to fix a few places that had incorrectly hard-coded the fact that a host always had exactly two ports (both ata_pci_init_bmdma() and ata_request_legacy_irqs() would just always iterate over both ports).

* | power management: implement pm_ops.valid for everybodyJohannes Berg2007-04-301-2/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Almost all users of pm_ops only support mem sleep, don't check in .valid and don't reject any others in .prepare so users can be confused if they check /sys/power/state, especially when new states are added (these would then result in s-t-r although they're supposed to be something different). This patch implements a generic pm_valid_only_mem function that is then exported for users and puts it to use in almost all existing pm_ops.

As soon as the controller was initialized --- i.e. right after modprobe ohci1394 --- this entry triggered a hotplug event which typically caused auto-loading of eth1394. This irritated or annoyed many users and distributors. Of course they could blacklist eth1394, but then ieee1394 wrongly advertized IP-over- 1394 capability to the FireWire bus. Therefore - remove the offending kernel config option IEEE1394_CONFIG_ROM_IP1394, - let eth1394 add the ROM entry by itself, i.e. only after eth1394 was loaded. This fixes http://bugzilla.kernel.org/show_bug.cgi?id=7793 . To emulate the behaviour of older kernels, simply add the following to to /etc/modprobe.conf: install ohci1394 /sbin/modprobe eth1394; \ /sbin/modprobe --ignore-install ohci1394 Note, autoloading of eth1394 when an _external_ IP-over-1394 capable device is discovered is _not_ affected by this patch.
