2017-06-11sched/core: Idle_task_exit() shouldn't use switch_mm_irqs_off()Andy Lutomirski
idle_task_exit() can be called with IRQs on x86 on and therefore should use switch_mm(), not switch_mm_irqs_off(). This doesn't seem to cause any problems right now, but it will confuse my upcoming TLB flush changes. Nonetheless, I think it should be backported because it's trivial. There won't be any meaningful performance impact because idle_task_exit() is only used when offlining a CPU.

2017-06-10net: mvpp2: use {get, put}_cpu() instead of smp_processor_id()Thomas Petazzoni
smp_processor_id() should not be used in migration-enabled contexts. We originally thought it was OK in the specific situation of this driver, but it was wrong, and calling smp_processor_id() in a migration-enabled context prints a big fat warning when CONFIG_DEBUG_PREEMPT=y. Therefore, this commit replaces the smp_processor_id() in migration-enabled contexts by the appropriate get_cpu/put_cpu sections.

2017-06-10net: mvpp2: remove mvpp2_bm_cookie_{build,pool_get}Thomas Petazzoni
This commit removes the useless remove mvpp2_bm_cookie_{build,pool_get} functions. All what mvpp2_bm_cookie_build() was doing is compute a 32-bit value by concatenating the pool number and the CPU number... only to get the pool number re-extracted by mvpp2_bm_cookie_pool_get() later on. Instead, just get the pool number directly from RX descriptor status, and pass it to mvpp2_pool_refill() and mvpp2_rx_refill(). This has the added benefit of dropping a smp_processor_id() call in a migration-enabled context, which is wrong, and is the original motivation for making this change.

Now sctp holds read_lock when foreach sctp_ep_hashtable without disabling BH. If CPU schedules to another thread A at this moment, the thread A may be trying to hold the write_lock with disabling BH. As BH is disabled and CPU cannot schedule back to the thread holding the read_lock, while the thread A keeps waiting for the read_lock. A dead lock would be triggered by this.

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs Pull btrfs fixes from Chris Mason: "Some fixes that Dave Sterba collected. We've been hitting an early enospc problem on production machines that Omar tracked down to an old int->u64 mistake. I waited a bit on this pull to make sure it was really the problem from production, but it's on ~2100 hosts now and I think we're good. Omar also noticed a commit in the queue would make new early ENOSPC problems. I pulled that out for now, which is why the top three commits are younger than the rest. Otherwise these are all fixes, some explaining very old bugs that we've been poking at for a while" * 'for-linus-4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs: Btrfs: fix delalloc accounting leak caused by u32 overflow Btrfs: clear EXTENT_DEFRAG bits in finish_ordered_io btrfs: tree-log.c: Wrong printk information about namelen btrfs: fix race with relocation recovery and fs_root setup btrfs: fix memory leak in update_space_info failure path btrfs: use correct types for page indices in btrfs_page_exists_in_range btrfs: fix incorrect error return ret being passed to mapping_set_error btrfs: Make flush bios explicitely sync btrfs: fiemap: Cache and merge fiemap extent before submit it to user

2017-06-10Bluetooth: use constant time memory comparison for secret valuesJason A. Donenfeld
This file is filled with complex cryptography. Thus, the comparisons of MACs and secret keys and curve points and so forth should not add timing attacks, which could either result in a direct forgery, or, given the complexity, some other type of attack.
