In order to use the new execute_in_process_context() API, you have to provide it with the work storage, which I do in SCSI in scsi_device and scsi_target, but which also means that we can no longer queue up the target reaps, so instead I moved the target to a state model which allows target_alloc to detect if we've received a dying target and wait for it to be gone. Hopefully, this should also solve the target namespace race. Signed-off-by:James Bottomley <James.Bottomley@SteelEye.com>

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.

When the locking was changed in the eh code ips_eh_reset was changed so that it was a wraper around __ips_eh_reset and all ips_eh_reset does is grab the host lock and then calls __ips_eh_reset. In the queuecommand, ips_queue is called with the host_lock held so if it calls ips_eh_reset we will have a problem. This patch just has ips_queue call __ips_eh_reset. Patch is only compile tested. I do not have the HW. Signed-off-by:

Regardless what mode page was asked for, Initio INIC-14x0 and INIC-2430 always return page 6 without mode page headers. Try to recognise this as a special case in scsi_mode_sense and setting the mode sense headers accordingly. Signed-off-by:

Some non-standard SCSI targets or protocols, such as USB UFI, report "no LUN present" by setting the Peripheral Device Type to 0x1f and the Peripheral Qualifier to 0 (not 3 as the standard requires) in the INQUIRY response. This patch (as650b) adds a new target flag and code to accomodate such targets. Signed-off-by:

New version that switches to the common onstack completion and just a pointer in the platform_data struct idiom. This gets rid of all the flags fiddling. Signed-off-by:

in __scsi_add_device, sdev may be uninitialised if scsi_host_scan_allowed() returns false. Fix by initialising at the top of the routine. Also rely on the fact that scsi_probe_and_add_lun() only actually fills in the sdev pointer if the SCSI_SCAN_LUN_PRESENT case (so no need to check the return value). Signed-off-by: -

As devfs has been disabled from the kernel tree for a number of months now (5 to be exact), here's a patch against 2.6.16-rc1-git1 that removes support for it from the SCSI subsystem. The patch also removes the scsi_disk devfs_name field as it's no longer needed. Signed-off-by:

The change to kernel/sched.c's init code to use for_each_cpu() requires that the cpu_possible_map be setup much earlier. Set it up via setup_arch(), constrained to NR_CPUS, and later constrain it to max_cpus in smp_prepare_cpus(). This fixes SMP booting on sparc64. Signed-off-by:David S. Miller <davem@davemloft.net>

Commit 9c869eda broke voyager again rather subtly because it already had its own topology exporting functions, so now each CPU gets registered twice. I think we can actually use the generic ones, so I don't propose reverting it. The attached should eliminate the voyager topology functions in favour of the generic ones. I also added a define to ensure voyager is never hotplug CPU (we don't have the support in the SMP harness). Signed-off-by:

The previous experiment for using apicmaintimer on ATI systems didn't work out very well. In particular laptops with C2/C3 support often don't let it tick during idle, which makes it useless. There were also some other bugs that made the apicmaintimer often not used at all. I tried some other experiments - running timer over RTC and some other things but they didn't really work well neither. I rechecked the specs now and it turns out this simple change is actually enough to avoid the double ticks on the ATI systems. We just turn off IRQ 0 in the 8254 and only route it directly using the IO-APIC. I tested it on a few ATI systems and it worked there. In fact it worked on all chipsets (NVidia, Intel, AMD, ATI) I tried it on. According to the ACPI spec routing should always work through the IO-APIC so I think it's the correct thing to do anyways (and most of the old gunk in check_timer should be thrown away for x86-64). But for 2.6.16 it's best to do a fairly minimal change: - Use the known to be working everywhere-but-ATI IRQ0 both over 8254 and IO-APIC setup everywhere - Except on ATI disable IRQ0 in the 8254 - Remove the code to select apicmaintimer on ATI chipsets - Add some boot options to allow to override this (just paranoia) In 2.6.17 I hope to switch the default over to this for everybody.

SMP time selection originally ran after all CPUs were brought up because it needed to know the number of CPUs to decide if it needs an MP safe timer or not. This is not needed anymore because we know present CPUs early. This fixes a couple of problems: - apicmaintimer didn't always work because it relied on state that was set up time_init_gtod too late. - The output for the used timer in early kernel log was misleading because time_init_gtod could actually change it later. Now always print the final timer choice Signed-off-by:

ACPI is initialized very early on x86-64, before the DMI code is initialized. This means it would often discover a 0 year and then turn off ACPI because it thought the BIOS was too old. Some systems don't boot without ACPI so this was a problem. I have a full fix by adding new very early DMI detection, but it needs more testing before it can be merged. For 2.6.16 let's just turn the check off. It never made much sense anyways because there are no x86-64 systems older than 2002 or so and they generally all have working ACPI.

This makes x86-64 use the common X86_PM_TIMER Kconfig entry in drivers/acpi And since PM timer is needed for correct timing on a lot of systems now (e.g. AMD dual cores) and we often get bug reports from people who forgot to set it make it depend on CONFIG_EMBEDDED. x86-64 had this change before and it's a good thing. I also fixed the description slightly to make this more clear. Cc: len.brown@intel.com Signed-off-by:
