2010-09-01net sched: fix kernel leak in act_policeJeff Mahoney
While reviewing commit 1c40be12f7d8ca1d387510d39787b12e512a7ce8, I audited other users of tc_action_ops->dump for information leaks. That commit covered almost all of them but act_police still had a leak. opt.limit and opt.capab aren't zeroed out before the structure is passed out. This patch uses the C99 initializers to zero everything unused out. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Acked-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: David S.

2010-09-01spi/spi_s3c64xx: Make probe more robust against missing board configMark Brown
The S3C64xx SPI driver requires the machine to call s3c64xx_spi_set_info() to select a few options, including the clock to use for the SPI controller. If this is not done then a NULL will be passed as the clock name for clk_get(), causing an obscure crash. Guard against this and other missing configuration by validating that the clock name has been filled in in the platform data that ets passed in.

2010-09-01ARM: 6343/1: wire up fanotify and prlimit64 syscalls on ARMMikael Pettersson
The 2.6.36-rc kernel added three new system calls: fanotify_init, fanotify_mark, and prlimit64. This patch wires them up on ARM. The only non-trivial issue here is the u64 argument to sys_fanotify_mark(), but it is the 3rd argument and thus passed in r2/r3 in both kernel and user space, so it causes no problems. Tested with a 2.6.36-rc2 EABI kernel on an ixp4xx machine.

2010-09-01lockup_detector: Sync touch_*_watchdog back to old semanticsDon Zickus
During my rewrite, the semantics of touch_nmi_watchdog and touch_softlockup_watchdog changed enough to break some drivers (mostly over preemptable regions). These are cases where long delays on one CPU (due to print_delay for example) can cause long delays on other CPUs - so we must 'touch' the nmi_watchdog flag of those other CPUs as well. This change brings those touch_*_watchdog() functions back in line with to how they used to work.
