Firmware semantics changed for 24xx and above ISPs in their handling of the specified execution-throttle passed during firmware initialization. The original codes use of a theoretical maximum (0xffff, as carried over from earlier ISPs) could in fact act as a throttle in some circumstances. Now set the value based of the firmware's own 'resource' (exchange IOCBs) capabilities.

The original code to 'resize request-queues' based on iocb-counts and employed during early ISP23xx testing was too overly-pessimistic with regards to latencies in the firmware pulling requests. Recent ISPs can easily keep up processing a stream of commands from an abbreviated (effectively, half the original size) queue.

When IRQs are shared by multiple controllers and if the first one to register does not disable the IRQ, then IRQ will be enabled for all other controllers by default, irrespective of their setting. With IRQF_DISABLED registration, the driver interrupt routine was called with interrupt enabled always. Disbaling the registration with IRQF_DISABLED, since driver code is re-entrant safe and all critical sections are guarded with interrupt safe locks.

Ensure that an ISP-abort has completed before performing any update. After the update do not wait for an ISP-abort completion, instead just wait until the ISP is reset.

Given the low-level interface varies from one flash-part manufacturer to the next, the Flash-Access-Control (FAC) mailbox command makes the specific flash type transparent to the driver by encapsulating a basic set of accessor and update routines.

The ibmvfc driver currently breaks the CRQ and essentially resets the entire virtual FC adapter, killing all outstanding ops to all attached targets, if an ADISC times out during target discover/rediscovery.

This patch fixes a problem of possible dropped interrupts. Currently, the ibmvfc driver has a race condition where after ibmvfc_interrupt gets run, the platform code clears the interrupt. This can result in lost interrupts and, in worst case scenarios, result in command timeouts. Fix this by implementing a tasklet similar to what the ibmvscsi driver does so that interrupt processing is no longer done in the actual interrupt handler, which eliminates the race.

Fix slab corruption caused by alloc_cpumask_var_node() overwriting the tail end of an off-stack cpumask. The function zeros out cpumask bits beyond the last possible cpu. The starting point for zeroing should be the beginning of the mask offset by a byte count derived from the number of possible cpus. The offset was calculated in bits instead of bytes. This resulted in overwriting the end of the cpumask.

SGI has observed that on large systems, interrupts are not serviced for a long period of time when waiting for a rwlock. The following patch series re-enables irqs while waiting for the lock, resembling the code which is already there for spinlocks. I only made the ia64 version, because the patch adds some overhead to the fast path. I assume there is currently no demand to have this for other architectures, because the systems are not so large. Of course, the possibility to implement raw_{read|write}_lock_flags for any architecture is still there. This patch: The new macro LOCK_CONTENDED_FLAGS expands to the correct implementation depending on the config options, so that IRQ's are re-enabled when possible, but they remain disabled if CONFIG_LOCKDEP is set.
