The mptspi modules has its own reset callback handler, just recently added for issuing domain validation after host reset. If either the mptsas or mptfc driver are loaded, this callback could be called. Thus resulting in domain validation being issued for sas or fibre end devices. Fix this by having mptbase.c check the bus type against the driver type and only call the reset handler if they match (or if it's a non-bus specific reset handler).

Problem only occured when qeth was built without IPV6 support. - avoid skb usage after invocation of qeth_flush_buffers, because skb might already be freed. - remove yet another useless netif_wake_queue in qeth_softsetup_ipv6 since this function is only called when device is going online. In this case card->state will never be in state UP. So let the net_device queue down .

To fix all problems at once recovery of lcs devices has been improved. missing error checks in lcs interrupt handler has been added. Once a hardware problem occurs lcs will recover the device now properly.

However, to verify the PCRs, the event-data must be a actual binary event-data used by SHA1 calc. in BIOS. So, I think actual ACPI TCPA log is good for this binary output format.

This is a temporary fix until we get proper ACPI handling in IPMI. Fixed releasing already-allocated regions when a later request fails, and forward-ported it to HEAD. Some BIOSes reserve disjoint I/O regions in their ACPI tables for the IPMI controller. This causes problems when trying to register the entire I/O region. Therefore we must register each I/O port separately.

The IDE part of the IOC4 chip uses MMIO to map the chip registers. Unfortunately, the sgiioc4 driver uses the default port IO operations, which happens to have worked for the past few years. That's about to change, however, thus this change from inX/outX to readX/writeX.

However sysfs_notify grabs a mutex and so cannot be called in interrupt context. This patch just creates a variant of md_new_event which avoids the sysfs call, and uses that. A better fix for later is to arrange for the event to be called from user-context. Note: avoiding the sysfs call isn't a problem as an error will not, by itself, modify the sync_action attribute. (We do still need to wake_up(&md_event_waiters) as an error by itself will modify /proc/mdstat).
