| * [PATCH] sky2: netconsole suspend/resume interactionStephen Hemminger2006-06-17
| | | | | | | | | | | | | | | | | | | | | | | | | | A couple of fixes that should prevent crashes when using netconsole and suspend/resume. First, netconsole poll routine shouldn't run unless the device is up; second, the NAPI poll should be disabled during suspend. This is only an issue on sky2, because it has to have one NAPI poll routine for both ports on dual port boards. Normal drivers use netif_rx_schedule_prep and that checks for netif_running.

| * [PATCH] fix cdrom openJens Axboe2006-06-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some time ago the cdrom open routine was changed so that we call the driver's open routine before checking to see if it is read only. However, if we discovered that a read write open was not possible and the open flags required a writable open, we just returned -EROFS without calling the driver's release routine. This seems to work for most cdrom drivers, but breaks the Powerpc iSeries virtual cdrom rather badly. This just inserts the release call in the error path to balance the call to "->open()" done by "open_for_data()".

| * | | ACPI: use for_each_possible_cpu() instead of for_each_cpu()KAMEZAWA Hiroyuki2006-05-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | for_each_cpu() actually iterates across all possible CPUs. We've had mistakes in the past where people were using for_each_cpu() where they should have been iterating across only online or present CPUs. This is inefficient and possibly buggy. We're renaming for_each_cpu() to for_each_possible_cpu() to avoid this in the future.

It appears on the USB bus when enabled. It can be controlled via hot key, or directly via ACPI. This change enables direct control via ACPI. I have tested it on my Lenovo Thinkpad X60; I guess it will probably work on other Thinkpad models which come with this module installed.

More consistent, and we'll find bugs faster if we fault rather than returning an error that's ignored. Also makes internal functions acpi_device_unregister() and acpi_driver_detach() void, since nobody uses their returns either.

Since the hardware for this driver is not hot-pluggable, determine whether the hardware is present by noticing calls to the .add() method. It would be better to probe the ACPI namespace for the ASUS HIDs, and load the driver only when we find one, but ACPI doesn't support that yet. I don't have an ASUS laptop to test on, but on my HP dl360, it does report the appropriate error when attempting to load the module: $ sudo insmod drivers/acpi/asus_acpi.ko insmod: error inserting 'drivers/acpi/asus_acpi.ko': -1 No such device Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Len Brown <len.brown@intel.com>

Previously we ignored the resource_type, so I/O ports and bus number ranges were incorrectly parsed as memory ranges. Sample PCI root bridge resources from HP rx2600 before this patch: # cat /sys/bus/pnp/devices/00:02/resources state = active mem 0x0-0x1f mem 0x0-0x3af mem 0x3e0-0x1fff mem 0x80000000-0x8fffffff With this patch: # cat /sys/bus/pnp/devices/00:02/resources state = active io 0x0-0x3af io 0x3e0-0x1fff mem 0x80000000-0x8fffffff mem 0x80004000000-0x80103fffffe Changes: 0x0-0x1f PCI bus number range was incorrectly reported as memory, now not reported at all 0x0-0x3af I/O port range was incorrectly reported as memory 0x3e0-0x1fff I/O port range was incorrectly reported as memory 0x80004000000-0x80103fffffe memory range wasn't reported at all because we only support PNP_MAX_MEM (4) memory resources Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Len Brown <len.brown@intel.com>
