2011-04-04netfilter: ipset: references are protected by rwlock instead of mutexJozsef Kadlecsik7-56/+73
The timeout variant of the list:set type must reference the member sets. However, its garbage collector runs at timer interrupt so the mutex protection of the references is a no go. Therefore the reference protection is converted to rwlock. Signed-off-by: Jozsef Kadlecsik <[email protected]> Signed-off-by: Patrick McHardy <[email protected]>

2011-04-04[S390] compile fix for latest binutilsMartin Schwidefsky1-1/+1
The latest binutils won't accept the stfl instruction with march=g5 which is the correct behaviour. Unfortunately head.S is assembled with -march=g5 even if the target cpu is z900 or later. To get 31-bit kernels compiled again the easiest fix is to use the .insn notation for the stfl instruction in head.S. Signed-off-by: Martin Schwidefsky <[email protected]>
2011-04-04[S390] cio: prevent purging of CCW devices in the online statePeter Oberparleiter1-6/+18
The cio_ignore purge function is intended to only remove CCW devices which are in the offline state. There is a time frame after the purge function finished where a CCW device is scheduled for removal but still accessible. When the device is set online during this time frame, it may first appear online before it is then removed. Fix this by preventing that CCW devices can be set online while there is work (such as removal triggered by the purge function) for it pending. Also ensure that the purge function does not schedule devices for removal which are in the process of being set online.

2011-04-04[S390] Fix parameter passing for smp_switch_to_cpu()Michael Holzheu2-2/+6
After the execution has been switched to the destination CPU, the target function is called with the wrong parameter. According to the C calling convention on s390, the first parameter should be loaded into register 2. Currently in smp_restart_cpu() it is stored in register 3. To fix this, we load the parameter into the correct register 2. Signed-off-by: Michael Holzheu <[email protected]> Signed-off-by: Martin Schwidefsky <[email protected]>

2011-04-03ASoC: format_register_str: Don't clip register valuesStephen Warren1-4/+4
wordsize is used as the textual width of a register address. regsize is used as the textual width of a register value. The assignments to these values were swapped. In the case of WM8903, which has 8-bit register addresses and 16-bit register values, this caused the register values to be clipped to 2 digits instead of the full 4.

2011-04-03ASoC: PXA: Fix oops in __pxa2xx_pcm_prepareVasily Khoruzhick2-0/+4
pxa2xx_pcm_hw_free frees dma channel and sets prtd->dma_ch to -1, but does not set prtd->params to NULL, so if pxa2xx_pcm_hw_params will be called immediately, it leaves prtd->dma_ch initialized with -1, and it results in oops in __pxa2xx_pcm_prepare. This bug is triggered via SDL. This patch adds check for prtd->dma_ch to __pxa2xx_pcm_prepare and cleans prtd->params, so now it works properly.

2011-04-01usbnet: use eth%d name for known ethernet devicesArnd Bergmann11-12/+23
The documentation for the USB ethernet devices suggests that only some devices are supposed to use usb0 as the network interface name instead of eth0. The logic used there, and documented in Kconfig for CDC is that eth0 will be used when the mac address is a globally assigned one, but usb0 is used for the locally managed range that is typically used on point-to-point links. Unfortunately, this has caused a lot of pain on the smsc95xx device that is used on the popular pandaboard without an EEPROM to store the MAC address, which causes the driver to call random_ether_address(). Obviously, there should be a proper MAC addressed assigned to the device, and discussions are ongoing about how to solve this, but this patch at least makes sure that the default interface naming gets a little saner and matches what the user can expect based on the documentation, including for new devices. The approach taken here is to flag whether a device might be a point-to-point link with the new FLAG_POINTTOPOINT setting in the usbnet driver_info. A driver can set both FLAG_POINTTOPOINT and FLAG_ETHER if it is not sure (e.g. cdc_ether), or just one of the two. The usbnet framework only looks at the MAC address for device naming if both flags are set, otherwise it trusts the flag.

2011-04-01ALSA: pcm: fix infinite loop in snd_pcm_update_hw_ptr0()Kelly Anderson1-1/+3
When period interrupts are disabled, snd_pcm_update_hw_ptr0() compares the current time against the time estimated for the current hardware pointer to detect xruns. The somewhat fuzzy threshold in the while loop makes it possible that hdelta becomes negative; the comparison being done with unsigned types then makes the loop go through the entire 263 negative range, and, depending on the value, never reach an unsigned value that is small enough to stop the loop. Doing this with interrupts disabled results in the machine locking up. To prevent this, ensure that the loop condition uses signed types for both operands so that the comparison is correctly done. Many thanks to Kelly Anderson for debugging this.

2011-04-01kdump: Allow shrinking of kdump region to be overriddenAnton Blanchard2-2/+4
On ppc64 the crashkernel region almost always overlaps an area of firmware. This works fine except when using the sysfs interface to reduce the kdump region. If we free the firmware area we are guaranteed to crash. Rename free_reserved_phys_range to crash_free_reserved_phys_range and make it a weak function so we can override it.
