| * Staging: fix wireless drivers dependsRandy Dunlap2009-10-303-3/+3
| | | | | | | | | | | | | | | | | | | | These drivers can (erroneously) be enabled even when CONFIG_NET=n, CONFIG_NETDEVICES=n, CONFIG_WLAN=n, etc. Stop this. Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| * Staging: android: mark subsystem as brokenGreg Kroah-Hartman2009-10-301-0/+1
| | | | | | | | | | | | | | | | It's causing lots of build errors, so just mark it as broken. It is scheduled to be removed in 2.6.33 anyway. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| | | | | | | | | | | | | | | | | | | | | | It's no longer needed as the p54spi driver is the same thing, under a different name and in the correct portion of the kernel tree.

| * Staging: rtl8187se/rtl8192e/rtl8192su: allow module unloadHerton Ronaldo Krzesinski2009-10-3012-96/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | On rtl81* additions, they had its wireless stack made builtin instead of separated modules. But try_module_get/module_put in stack were kept, they are uneeded with the stack builtin and makes rtl81* modules impossible to remove on a system with an rtl81* card. request_module calls are also uneeded with stack builtin, so remove them too.

The patch "sierra_close() must resume the device before it notifies it of a closure" submitted by Oliver Neukum on Wed, October 14 has been merged as fix in sierra_close() function. The bug fix in sierra_open() function restores the autopm interface state on error condition. The bug fix in in stop_read_write_urbs() function assures that both receive and interrupt urbs are recycled.

| * | USB: serial: sierra driver send_setup() autopm fixElina Pasheva2009-10-301-10/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch presents a fix for the autosuspend feature implementation in sierra usb serial driver for function sierra_send_setup(). Because it is possible to call sierra_send_setup() before sierra_open() or after sierra_close() we added a get/put interface activity to assure that the usb control can happen even when the device is autosuspended.

But the returned error code was wrong: to modprobe, the -EEXIST means that _this_ driver is already installed. It therefore doesn't produce the needed error message when _another_ driver is trying to register for the same device. Returning -EBUSY fixes the problem.

If the status of the sensed cpu is all zeros condition code 0 (accpeted) is set and no status bits are returned. The current code however assumes that a status was returned and tests bits in it. This means uninitalized data is accessed with random results. Worst case is that the code that checks if cpu is offline on cpu hotplug assumes that the target cpu is offline while it is still running. This leads potentially to memory corruption since resources that are still needed by the target cpu will be freed and could be resused while still in use.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Offlined cpus still have valid prefix register contents. Dumpers will store the register contents of a cpu to the location where its prefix register points to. For offlined cpus the area (lowcore) has been freed and the dumper would write the uninteresting contents of the offline cpu to a memory location which might be in use by some other component and destroy valueable information. To fix this set the prefix register of offline cpus to absolute address zero again. This prevents the current dumpers to write to random memory locations.

Quoting from commit 0a82a623: In these situations the default N-disk algorithm will present 0-source or 1-source operations to dma devices. To cover for dma devices where the minimum source count is 2 we implement 4-disk and 5-disk handling in the recovery code. The ddf layout presents disks=6 and disks=7 to the recovery code in these situations. Instead of looking at the number of disks count the number of non-zero sources in the list and call the special case code when the number of non-failed sources is 0 or 1.
