Commit 50bed2e2 ("sg: disable interrupts inside sg_copy_buffer") introduced disabling interrupts in sg_copy_buffer() since atomic uses of miter required it due to use of kmap_atomic(). However, as commit 8290e2d2 ("scatterlist: atomic sg_mapping_iter() no longer needs disabled IRQs") acknowledges disabling interrupts is no longer needed for calls to kmap_atomic() and therefore unneeded for miter ops either, so remove it from sg_copy_buffer().

The issue is described here, with a nice testcase: https://bugzilla.kernel.org/show_bug.cgi?id=192931 The problem is that shmat() calls do_mmap_pgoff() with MAP_FIXED, and the address rounded down to 0. For the regular mmap case, the protection mentioned above is that the kernel gets to generate the address -- arch_get_unmapped_area() will always check for MAP_FIXED and return that address. So by the time we do security_mmap_addr(0) things get funky for shmat(). The testcase itself shows that while a regular user crashes, root will not have a problem attaching a nil-page. There are two possible fixes to this. The first, and which this patch does, is to simply allow root to crash as well -- this is also regular mmap behavior, ie when hacking up the testcase and adding mmap(... |MAP_FIXED). While this approach is the safer option, the second alternative is to ignore SHM_RND if the rounded address is 0, thus only having MAP_SHARED flags. This makes the behavior of shmat() identical to the mmap() case. The downside of this is obviously user visible, but does make sense in that it maintains semantics after the round-down wrt 0 address and mmap. Passes shm related ltp tests.

sysv sem has two lock modes: One with per-semaphore locks, one lock mode with a single global lock for the whole array. When switching from the per-semaphore locks to the global lock, all per-semaphore locks must be scanned for ongoing operations. The patch adds a hysteresis for switching from the global lock to the per semaphore locks. This reduces how often the per-semaphore locks must be scanned. Compared to the initial patch, this is a simplified solution: Setting USE_GLOBAL_LOCK_HYSTERESIS to 1 restores the current behavior. In theory, a workload with exactly 10 simple sops and then one complex op now scales a bit worse, but this is pure theory: If there is concurrency, the it won't be exactly 10:1:10:1:10:1:... If there is no concurrency, then there is no need for scalability. Link: http://lkml.kernel.org/r/1476851896-3590-3-git-send-email-manfred@colorfullife.comSigned-off-by:

a) The ACQUIRE in spin_lock() applies to the read, not to the store, at least for powerpc. This forces to add a smp_mb() into the fast path. b) The memory barrier provided by spin_unlock_wait() is right now arch dependent. Therefore: Use spin_lock()/spin_unlock() instead of spin_unlock_wait(). Advantage: faster single op semop calls(), observed +8.9% on x86. (the other solution would be arch dependencies in ipc/sem). Disadvantage: slower complex op semop calls, if (and only if) there are no sleeping operations. The next patch adds hysteresis, this further reduces the probability that the slow path is used.

Commit 4a9d4b02 ("switch fput to task_work_add") implements a schedule_work() for completing fput(), but did not guarantee calling __fput() after unpacking initramfs. Because of this, there is a possibility that during boot a driver can see ETXTBSY when it tries to load a binary from initramfs as fput() is still pending on that binary. This patch makes sure that fput() is completed after unpacking initramfs and removes the call to flush_delayed_fput() in kernel_init() which happens very late after unpacking initramfs.
