Pull irq fixes from Thomas Gleixner: "Three fixes for irq core and irq chip drivers: - Do not set the irq type if type is NONE. Fixes a boot regression on various SoCs - Use the proper cpu for setting up the GIC target list. Discovered by the cpumask debugging code. - A rather large fix for the MIPS-GIC so per cpu local interrupts work again.

Merge VM fixes from High Dickins: "I get the impression that Andrew is away or busy at the moment, so I'm going to send you three independent uncontroversial little mm fixes directly - though none is strictly a 4.8 regression fix. - shmem: fix tmpfs to handle the huge= option properly from Toshi Kani is a one-liner to fix a major embarrassment in 4.8's hugepages on tmpfs feature: although Hillf pointed it out in June, somehow both Kirill and I repeatedly dropped the ball on this one. You might wonder if the feature got tested at all with that bug in: yes, it did, but for wider testing coverage, Kirill and I had each relied too much on an override which bypasses that condition. - huge tmpfs: fix Committed_AS leak just a run-of-the-mill accounting fix in the same feature. - mm: delete unnecessary and unsafe init_tlb_ubc() is an unrelated fix to 4.3's TLB flush batching in reclaim: the bug would be rare, and none of us will be shamed if this one misses 4.8; but it got such a quick ack from Mel today that I'm inclined to offer it along with the first two" * emailed patches from Hugh Dickins <hughd@google.com>: mm: delete unnecessary and unsafe init_tlb_ubc() huge tmpfs: fix Committed_AS leak shmem: fix tmpfs to handle the huge= option properly

init_tlb_ubc() looked unnecessary to me: tlb_ubc is statically initialized with zeroes in the init_task, and copied from parent to child while it is quiescent in arch_dup_task_struct(); so I went to delete it. But inserted temporary debug WARN_ONs in place of init_tlb_ubc() to check that it was always empty at that point, and found them firing: because memcg reclaim can recurse into global reclaim (when allocating biosets for swapout in my case), and arrive back at the init_tlb_ubc() in shrink_node_memcg(). Resetting tlb_ubc.flush_required at that point is wrong: if the upper level needs a deferred TLB flush, but the lower level turns out not to, we miss a TLB flush. But fortunately, that's the only part of the protocol that does not nest: with the initialization removed, cpumask collects bits from upper and lower levels, and flushes TLB when needed.

Under swapping load on huge tmpfs, /proc/meminfo's Committed_AS grows bigger and bigger: just a cosmetic issue for most users, but disabling for those who run without overcommit (/proc/sys/vm/overcommit_memory 2). shmem_uncharge() was forgetting to unaccount __vm_enough_memory's charge, and shmem_charge() was forgetting it on the filesystem-full error path.

The wq_numa_init() function makes a private CPU to node map by calling cpu_to_node() early in the boot process, before the non-boot CPUs are brought online. Since the default implementation of cpu_to_node() returns zero for CPUs that have never been brought online, the workqueue system's view is that *all* CPUs are on node zero. When the unbound workqueue for a non-zero node is created, the tsk_cpus_allowed() for the worker threads is the empty set because there are, in the view of the workqueue system, no CPUs on non-zero nodes. The code in try_to_wake_up() using this empty cpumask ends up using the cpumask empty set value of NR_CPUS as an index into the per-CPU area pointer array, and gets garbage as it is one past the end of the array. This results in: [ 0.881970] Unable to handle kernel paging request at virtual address fffffb1008b926a4 [ 1.970095] pgd = fffffc00094b0000 [ 1.973530] [fffffb1008b926a4] *pgd=0000000000000000, *pud=0000000000000000, *pmd=0000000000000000 [ 1.982610] Internal error: Oops: 96000004 [#1] SMP [ 1.987541] Modules linked in: [ 1.990631] CPU: 48 PID: 295 Comm: cpuhp/48 Tainted: G W 4.8.0-rc6-preempt-vol+ #9 [ 1.999435] Hardware name: Cavium ThunderX CN88XX board (DT) [ 2.005159] task: fffffe0fe89cc300 task.stack: fffffe0fe8b8c000 [ 2.011158] PC is at try_to_wake_up+0x194/0x34c [ 2.015737] LR is at try_to_wake_up+0x150/0x34c [ 2.020318] pc : [<fffffc00080e7468>] lr : [<fffffc00080e7424>] pstate: 600000c5 [ 2.027803] sp : fffffe0fe8b8fb10 [ 2.031149] x29: fffffe0fe8b8fb10 x28: 0000000000000000 [ 2.036522] x27: fffffc0008c63bc8 x26: 0000000000001000 [ 2.041896] x25: fffffc0008c63c80 x24: fffffc0008bfb200 [ 2.047270] x23: 00000000000000c0 x22: 0000000000000004 [ 2.052642] x21: fffffe0fe89d25bc x20: 0000000000001000 [ 2.058014] x19: fffffe0fe89d1d00 x18: 0000000000000000 [ 2.063386] x17: 0000000000000000 x16: 0000000000000000 [ 2.068760] x15: 0000000000000018 x14: 0000000000000000 [ 2.074133] x13: 0000000000000000 x12: 0000000000000000 [ 2.079505] x11: 0000000000000000 x10: 0000000000000000 [ 2.084879] x9 : 0000000000000000 x8 : 0000000000000000 [ 2.090251] x7 : 0000000000000040 x6 : 0000000000000000 [ 2.095621] x5 : ffffffffffffffff x4 : 0000000000000000 [ 2.100991] x3 : 0000000000000000 x2 : 0000000000000000 [ 2.106364] x1 : fffffc0008be4c24 x0 : ffffff0ffffada80 [ 2.111737] [ 2.113236] Process cpuhp/48 (pid: 295, stack limit = 0xfffffe0fe8b8c020) [ 2.120102] Stack: (0xfffffe0fe8b8fb10 to 0xfffffe0fe8b90000) [ 2.125914] fb00: fffffe0fe8b8fb80 fffffc00080e7648 . . .

An "exclusive" PMU is the one that can only have one event scheduled in at any given time. There may be more than one of such PMUs in a system, though, like Intel PT and BTS. It should be allowed to have one event for either of those inside the same context (there may be other constraints that may prevent this, but those would be hardware-specific). However, the exclusivity code is written so that only one event from any of the "exclusive" PMUs is allowed in a context. Fix this by making the exclusive event filter explicitly match two events' PMUs.

Just like intel_pt, intel_bts can only handle one event at a time, which is the reason we introduced PERF_PMU_CAP_EXCLUSIVE in the first place. However, at the moment one can have as many intel_bts events within the same context at the same time as one pleases. Only one of them, however, will get scheduled and receive the actual trace data. Fix this by making intel_bts an "exclusive" PMU.

Commit 815806e3 ("regmap: drop cache if the bus transfer error") added a call to regcache_drop_region() to error path in _regmap_raw_write(). However that path runs with regmap lock taken, and regcache_drop_region() tries to re-take it, causing a deadlock. Fix that by calling map->cache_ops->drop() directly.

As the software RSA implementation now produces fixed-length output, we need to eliminate leading zeros in the calling code instead.

Since the TFO socket is accepted right off SYN-data, the socket owner can call getsockopt(TCP_INFO) to collect ongoing SYN-ACK retransmission or timeout stats (i.e., tcpi_total_retrans, tcpi_retransmits). Currently those stats are only updated upon handshake completes. This patch fixes it.
