[PATCH v3 03/20] mm: Introduce pte_spinlock for FAULT_FLAG_SPECULATIVE

When handling page fault without holding the mmap_sem the fetch of the pte lock pointer and the locking will have to be done while ensuring that the VMA is not touched in our back. So move the fetch and locking operations in a dedicated function. Signed-off-by: Laurent Dufour

[PATCH v3 05/20] mm: Protect VMA modifications using VMA sequence count

The VMA sequence count has been introduced to allow fast detection of VMA modification when running a page fault handler without holding the mmap_sem. This patch provides protection against the VMA modification done in : - madvise() - mremap() - mpol_rebind_policy()

[PATCH v3 04/20] mm: VMA sequence count

From: Peter Zijlstra Wrap the VMA modifications (vma_adjust/unmap_page_range) with sequence counts such that we can easily test if a VMA is changed. The unmap_page_range() one allows us to make assumptions about page-tables; when we find the seqcount hasn't changed we can

[PATCH v3 06/20] mm: RCU free VMAs

From: Peter Zijlstra Manage the VMAs with SRCU such that we can do a lockless VMA lookup. We put the fput(vma->vm_file) in the SRCU callback, this keeps files valid during speculative faults, this is possible due to the delayed fput work by Al Viro -- do we need
