2009-09-22 media: video: Fix build in saa7164Ingo Molnar
-tip testing found that the x86 build (64-bit allyesconfig) fails due to: LD vmlinux.o drivers/built-in.o:(.bss+0x4b648): multiple definition of `debug' arch/x86/built-in.o:(.kprobes.text+0x88): first defined here ld: Warning: size of symbol `debug' changed from 90 in arch/x86/built-in.o to 4 in drivers/built-in.o make: *** [vmlinux.o] Error 1 This is because recent saa7164 changes introduced a global symbol named 'debug'. The x86 platform code already defines a 'debug' symbol. (which is named in a too generic way as well - but it can be used nicely to weed out too generic symbols in drivers ;-) Rename it to saa_debug.

2009-09-22smsc95xx: fix transmission where ZLP is expectedSteve Glendinning
Usbnet framework assumes USB hardware doesn't handle zero length packets, but SMSC LAN95xx requires these to be sent for correct operation. This patch fixes an easily reproducible tx lockup when sending a frame that results in exactly 512 bytes in a USB transmission (e.g. a UDP frame with 458 data bytes, due to IP headers and our USB headers). It adds an extra flag to usbnet for the hardware driver to indicate that it can handle and requires the zero length packets. This patch should not affect other usbnet users, please also consider for -stable. Signed-off-by: Steve Glendinning <steve.glendinning@smsc.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-09-22[S390] hibernate: Do real CPU swap at resume timeMichael Holzheu
Currently, when the physical resume CPU is not equal to the physical suspend CPU, we swap the CPUs logically, by modifying the logical/physical CPU mapping. This has two major drawbacks: First the change is visible from user space (e.g. CPU sysfs files) and second it is hard to ensure that nowhere in the kernel the physical CPU ID is stored before suspend. To fix this, we now really swap the physical CPUs, if the resume CPU is not the pysical suspend CPU. We restart the suspend CPU and stop the resume CPU using SIGP restart and SIGP stop. If the suspend CPU is no longer available, we write a message and load a disabled wait PSW.

2009-09-22[S390] dasd: tolerate devices that have no feature codesStefan Weinhuber
The DASD device driver reads the feature codes of a device during device initialization. These codes are later used to determine the availability of advanced features like PAV or High Performance FICON. Some very old devices do not support the command to read feature codes and the initialization routine fails. As the feature codes are not necessary for basic DASD operations, we can support such devices by just ignoring missing feature codes.

2009-09-22[S390] zcrypt: Do not add/remove devices in s/r callbacksFelix Beck
Devices are no longer removed or added in the suspend and resume callbacks. Instead they are marked unregistered in suspend. In the resume callback the ap_scan_bus method is scheduled. The bus scan function will remove the old device and add new ones. This way all the device handling will be done in only one function. Additionaly the case where the domain might change during suspend/resume is caught. In that case the devices qid needs to re-calculated in order of having it found by the scan method.

2009-09-22Btrfs: fix early enospc during balancingChris Mason
We now do extra checks before a balance to make sure there is room for the balance to take place. One of the checks was testing to see if we were trying to balance away the last block group of a given type. If there is no space available for new chunks, we should not try and balance away the last block group of a give type. But, the code wasn't checking for available chunk space, and so it was exiting too soon. The fix here is to combine some of the checks and make sure we try to allocate new chunks when we're balancing the last block group. Signed-off-by: Chris Mason <chris.mason@oracle.com>
