Introduce lpfc_reset_barrier() function for resets on dual channel adapters Workaround for a hardware errata on dual channel asics. There is a potential for the chip to lock up on a reset if a shared dma engine is in use. The (ugly) work around requires a reset process which uses a mailbox command to synchronize the independent channels prior to the reset to avoid the issue. Unfortunately, the timing windows required to ensure this workaround succeeds are very specific, meaning we can't release the cpu during the barrier.

- Add functionality to run in polled mode only. Includes run time attribute to enable mode. - Enable runtime writable hba settings for coallescing and delay parameters Customers have requested a mode in the driver to run strictly polled. This is generally to support an environment where the server is extremely loaded and is looking to reclaim some cpu cycles from adapter interrupt handling. This patch adds a new "poll" attribute, and the following behavior: if value is 0 (default): The driver uses the normal method for i/o completion. It uses the firmware feature of interrupt coalesing. The firmware allows a minimum number of i/o completions before an interrupt, or a maximum time delay between interrupts. By default, the driver sets these to no delay (disabled) or 1 i/o - meaning coalescing is disabled. Attributes were provided to change the coalescing values, but it was a module-load time only and global across all adapters. This patch allows them to be writable on a per-adapter basis. if value is 1 : Interrupts are left enabled, expecting that the user has tuned the interrupt coalescing values. When this setting is enabled, the driver will attempt to service completed i/o whenever new i/o is submitted to the adapter. If the coalescing values are large, and the i/o generation rate steady, an interrupt will be avoided by servicing completed i/o prior to the coalescing thresholds kicking in. However, if the i/o completion load is high enough or i/o generation slow, the coalescion values will ensure that completed i/o is serviced in a timely fashion. if value is 3 : Turns off FCP i/o interrupts altogether. The coalescing values now have no effect. A new attribute "poll_tmo" (default 10ms) exists to set the polling interval for i/o completion. When this setting is enabled, the driver will attempt to service completed i/o and restart the interval timer whenever new i/o is submitted. This behavior allows for servicing of completed i/o sooner than the interval timer, but ensures that if no i/o is being issued, then the interval timer will kick in to service the outstanding i/o.

Analysis: Timeout of READ_SPARM64 causes call to lpfc_mbox_timeout_handler which reads psli->mbox_active to determine the timeout mbox. Timeout handler then NULL's psli->mbox_active and calls lpfc_mbx_cmpl_read_sparam(), which on timeout condition, calls link_down(). link_down() now calls disc_done() which calls mbox_timeout_hander() again since WORKER_MBOX_TMO is still set, which goes back to read psli->mbox_active which is already NULL'ed. Remove redundant if statement in lpfc_mbox_timeout_handler. pmbox is assigned psli->mbox_active so there is no need to check if it actually equals psli->mbox_active.
