* [PATCH] x86_64: Don't enable ATI apicmaintimer workaround when the machine ↵Andi Kleen2006-02-17
| | | | | | | | | | | | | has C2 or C3 Many laptops have problems with ticking the local APIC timer in C2/C3. The code added earlier to use it by default on ATI didn't really work for them. Don't enable it when the system supports C2/C3. This doesn't fix the problem fully, but at least it's not worse than before.

| | | | | | | | | | | | | AMD SimNow!'s JIT doesn't like them at all in the guest. For distribution installation it's easiest if it's a boot time option. Also I moved the variable to a more appropiate place and make it independent from sysctl And marked __read_mostly which it is.

| * [SCSI] fix wrong context bugs in SCSIJames Bottomley2006-02-14
| | | | | | | | | | | | | | | | | | | | | | | | There's a bug in releasing scsi_device where the release function actually frees the block queue. However, the block queue release calls flush_work(), which requires process context (the scsi_device structure may release from irq context). Update the release function to invoke via the execute_in_process_context() API. Also clean up the scsi_target structure releasing via this API. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
| * [PATCH] add scsi_execute_in_process_context() APIJames Bottomley2006-02-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have several points in the SCSI stack (primarily for our device functions) where we need to guarantee process context, but (given the place where the last reference was released) we cannot guarantee this. This API gets around the issue by executing the function directly if the caller has process context, but scheduling a workqueue to execute in process context if the caller doesn't have it. Unfortunately, it requires memory allocation in interrupt context, but it's better than what we have previously. The true solution will require a bit of re-engineering, so isn't appropriate for 2.6.16. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| * [SCSI] ipr: Fix adapter initialization failureBrian King2006-02-12
| | | | | | | | | | | | | | | | | | | | | | | | Since scsi core is always sending scatterlists now, remove some code which was written with the bad assumption that a small transfer would not be sent down in a scatterlist. Without this fix, the ipr driver ends up sending garbage data to the adapter following a reset, causing it to fail the reset and take the adapter offline.

In order to support user tools accessing the array components (SMART, Mode Page information, Cache page adjustments, WWN determination, Firmware updates etc), we take advantage of the no_uld_attach flag and deprecate the code that filters Inquiries to block the requests to array components. The quirk prevents the sd layer from attaching to the components. We also took the opportunity to balance the queue depths based on the total adapter queue depth to the array devices to reduce the chances of starvation.
