[PATCH 0/2] ACPI: Device enumeration udates

Hi, These two patches change a couple of things related to the ACPI enumeration of devices. [1/2] causes the default enumeration to also be used for device objects with ACPI drivers bound for consistency. [2/2] makes acpi_bus_attach() look at the "visited" flag of device objects as it should

[PATCH] slab: avoid IPIs when creating kmem caches

Each slab kmem cache has per cpu array caches. The array caches are created when the kmem_cache is created, either via kmem_cache_create() or lazily when the first object is allocated in context of a kmem enabled memcg. Array caches are replaced by writing to /proc/slabinfo. Array caches are

[PATCH v4 1/2] vfio/type1: Remove locked page accounting workqueue

If the mmap_sem is contented then the vfio type1 IOMMU backend will defer locked page accounting updates to a workqueue task. This has a few problems and depending on which side the user tries to play, they might be over-penalized for unmaps that haven't yet been accounted or race the workqueue

[PATCH v4 2/2] vfio/type1: Prune vfio_pin_page_external()

With vfio_lock_acct() testing the locked memory limit under mmap_sem, it's redundant to do it here for a single page. We can also reorder our tests such that we can avoid testing for reserved pages if we're not doing accounting, and test the process CAP_IPC_LOCK only if we are doing accounting.

[PATCH v4 0/2] vfio/type1: Synchronous locked page accounting

v4: vfio_lock_acct() should not fail due to RLIMIT_MEMLOCK if task has CAP_IPC_LOCK capability. Introduced 2nd patch to remove redundancy from vfio_pin_page_external() and fix return value. Please re-review. Thanks! Alex --- Alex Williamson (2): vfio/type1: Remove locked page
