smt_snooze_delay was designed to delay idle loop's nap entry in the native idle code before it got ported over to use as part of the cpuidle framework. A -ve value assigned to smt_snooze_delay should result in busy looping, in other words disabling the entry to nap state. - https://lists.ozlabs.org/pipermail/linuxppc-dev/2010-May/082450.html This particular functionality can be achieved currently by echo 1 > /sys/devices/system/cpu/cpu*/state1/disable but it is broken when one assigns -ve value to the smt_snooze_delay variable either via sysfs entry or ppc64_cpu util. This patch aims to fix this, by disabling nap state when smt_snooze_delay variable is set to -ve value.

Remove the redundant target residency initialisation in pseries_cpuidle_driver_init(). This is currently over-writing the residency time updated as part of the static table, resulting in all the idle states having the same target residency of 100us which is incorrect. This may result in the menu governor making wrong state decisions. Signed-off-by: NDeepthi Dharwar <deepthi@linux.vnet.ibm.com> Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

It seems I accidentally switched the guard on linux/elf-fdpic.h from #ifdef __KERNEL__ to #ifndef __KERNEL__ when attempting to expand the guarded region to cover the elf_fdpic_params struct when doing the UAPI split - with the result that the struct became unavailable to kernel code. Move incorrectly guarded bits back to the kernelspace header. Whilst we're at it, the __KERNEL__ guards can be deleted as they're no longer necessary.

When reading /proc/pid/numa_maps, it's possible to return the contents of the stack where the mempolicy string should be printed if the policy gets freed from beneath us. This happens because mpol_to_str() may return an error the stack-allocated buffer is then printed without ever being stored. There are two possible error conditions in mpol_to_str(): - if the buffer allocated is insufficient for the string to be stored, and - if the mempolicy has an invalid mode. The first error condition is not triggered in any of the callers to mpol_to_str(): at least 50 bytes is always allocated on the stack and this is sufficient for the string to be written. A future patch should convert this into BUILD_BUG_ON() since we know the maximum strlen possible, but that's not -rc material. The second error condition is possible if a race occurs in dropping a reference to a task's mempolicy causing it to be freed during the read(). The slab poison value is then used for the mode and mpol_to_str() returns -EINVAL. This race is only possible because get_vma_policy() believes that mm->mmap_sem protects task->mempolicy, which isn't true. The exit path does not hold mm->mmap_sem when dropping the reference or setting task->mempolicy to NULL: it uses task_lock(task) instead. Thus, it's required for the caller of a task mempolicy to hold task_lock(task) while grabbing the mempolicy and reading it. Callers with a vma policy store their mempolicy earlier and can simply increment the reference count so it's guaranteed not to be freed.

There was a serious disconnect in the logic happening in sparc_pmu_disable_event() vs. sparc_pmu_enable_event(). Event disable is implemented by programming a NOP event into the PCR. However, event enable was not reversing this operation. Instead, it was setting the User/Priv/Hypervisor trace enable bits. That's not sparc_pmu_enable_event()'s job, that's what sparc_pmu_enable() and sparc_pmu_disable() do . The intent of sparc_pmu_enable_event() is clear, since it first clear out the event type encoding field. So fix this by OR'ing in the event encoding rather than the trace enable bits.

由 Stefan Raspl 提交于
The recovery thread, when failing, tears down the respective interface. To do so, it needs to obtain the rtnl lock first, as the interface configuration is changed. If another process tries to modify an interface setting at the same time, that process can obtain the rtnl lock first, but the respective callback in the qeth driver will block until recovery has completed - which cannot happen since the calling process already obtained it. In one particular case, the bonding driver acquired the rtnl lock to modify the card's MAC address, while the recovery failed at the same time due to the card being removed. Hence qeth_l2_set_mac_address (implicitly holding the rtnl lock) was waiting on qeth_l2_recover, which deadlocked when waiting on the rtnl lock. This patch uses rtnl_trylock instead of rtnl_lock in the recovery thread. If the lock cannot be obtained, the interface will be left up, but the card state remains in CARD_STATE_RECOVER, which will prevent any further activities on the card.
