Prior to the introduction of fib6_info lwtstate was managed by the dst code. With fib6_info releasing lwtstate needs to be done when the struct is freed. Fixes: 93531c67 ("net/ipv6: separate handling of FIB entries from dst based routes") Signed-off-by:

Tomer Tayar says: ==================== qed: Misc fixes in the interface with the MFW This patch series fixes several issues in the driver's interface with the management FW (MFW). v1->v2: - Fix loop counter decrement to be pre instead of post. ==================== Signed-off-by: -

Keep sending mailbox commands to the MFW when it is not responsive ends up with a redundant amount of timeout expiries. This patch prints the MCP status on the first command which is not responded, and blocks the following commands. Since the (un)load request commands might be not responded due to other PFs, the patch also adds the option to skip the blocking upon a failure. Signed-off-by:

The MFW manages an internal lock to prevent concurrent hardware (de)initialization of different PFs. This, together with the busy-waiting for the MFW's responses for commands, might lead to a deadlock during concurrent load or unload of PFs. This patch adds the option to sleep within the busy-waiting, and uses it for the (un)load requests (which are not sent from an interrupt context) to prevent the possible deadlock. Signed-off-by:

Successive iterations of halting and resuming the management chip (MCP) might fail, since currently the driver doesn't wait for these operations to actually take place. This patch prevents the driver from moving forward before the operations are reflected in the state register. Signed-off-by:

The MFW might be reset and re-update its shared memory. Upon the detection of such a reset the driver rereads this memory, but it has to wait till the data is valid. This patch adds the missing wait for a data ready indication. Signed-off-by:

timekeeping_clocktai64() has been renamed to ktime_get_clocktai_ts64() for consistency with the other ktime_get_* access functions. Rename the new caller that has come up as well. Question: this is the only ptp driver that sets the hardware time to the current system time in TAI. Why does it do that? Signed-off-by:

Recently, ops->init() and ops->dump() of all actions were modified to always obtain tcf_lock when accessing private action state. Actions that don't depend on tcf_lock for synchronization with their data path use non-bh locking API. However, tcf_lock is also used to protect rate estimator stats in softirq context by timer callback. Change ops->init() and ops->dump() of all actions to disable bh when using tcf_lock to prevent deadlock reported by following lockdep warning: [ 105.470398] ================================ [ 105.475014] WARNING: inconsistent lock state [ 105.479628] 4.18.0-rc8+ #664 Not tainted [ 105.483897] -------------------------------- [ 105.488511] inconsistent {SOFTIRQ-ON-W} -> {IN-SOFTIRQ-W} usage.

Merge tag 'riscv-for-linus-4.19-mw0' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux Pull RISC-V updates from Palmer Dabbelt: "This contains some major improvements to the RISC-V port, including the necessary interrupt controller and timer support to actually make it to userspace. Support for three devices has been added: - the ISA-mandated timers on RISC-V systems. - the ISA-mandated first-level interrupt controller on RISC-V systems, which is handled as part of our core arch code because it's very small and tightly tied to the ISA. - SiFive's platform-level interrupt controller, which talks to the actual devices. In addition to these new devices, there are a handful of cleanups all over the RISC-V tree: - build fixes for various configurations: * A fix to the vDSO build's makefile so it respects CFLAGS. * The addition of __lshrti3, a libgcc derived function necessary for some 32-bit configurations. * !SMP && PERF_EVENTS - Cleanups to the arch code to remove the remnants of old versions of the drivers that were just properly submitted. * Some dead code from the timer driver, most of which wasn't ever even compiled. * Cleanups of some interrupt #defines, which are now local to the interrupt handling code. - Fixes to ptrace(), which while not being sufficient to fully make GDB work are at least sufficient to get simple GDB tasks to work. - Early printk support via RISC-V's architecturally mandated SBI console device. - A fix to our early debug trap handler to ensure it's always aligned. These patches have all been through a fairly extensive review process, but as this enables a whole pile of functionality (ie, userspace) I'm confident we'll need to submit a few more patches. The only concrete issues I know about are the sys_riscv_flush_icache patches, but as I managed to screw those up on Friday I figured it'd be best to let them bake another week. This tag boots a Fedora root filesystem on QEMU's master branch for me, and before this morning's rebase (from 4.18-rc8 to 4.18) it booted on the HiFive Unleashed.

This function was created as a deprecated fallback case back in 2010 by commit eb14120f ("pcmcia: re-work pcmcia_request_irq()") for legacy cases. Actual in-kernel users haven't been around for a long while. The last in-kernel user was apparently removed four years ago by commit 5f5316fc ("am2150: Update nmclan_cs.c to use update PCMCIA API"). Just remove it entirely. Signed-off-by:

We haven't had lots of deprecation warnings lately, but the rdma use of it made them flare up again. They are not useful. They annoy everybody, and nobody ever does anything about them, because it's always "somebody elses problem". And when people start thinking that warnings are normal, they stop looking at them, and the real warnings that mean something go unnoticed. If you want to get rid of a function, just get rid of it. Convert every user to the new world order. And if you can't do that, then don't annoy everybody else with your marking that says "I couldn't be bothered to fix this, so I'll just spam everybody elses build logs with warnings about my laziness". Make a kernelnewbies wiki page about things that could be cleaned up, write a blog post about it, or talk to people on the mailing lists. But don't add warnings to the kernel build about cleanup that you think should happen but you aren't doing yourself. Don't. Just don't. Signed-off-by: -

Even with adding all of the new drivers and a new filesystem, we are only adding about 1000 lines overall to the kernel linecount, which shows just how much cleanup happened, and how big the unused crypto driver was.

When perf profiling a wide variety of different workloads, it was found that vmacache_find() had higher than expected cost: up to 0.08% of cpu utilization in some cases. This was found to rival other core VM functions such as alloc_pages_vma() with thp enabled and default mempolicy, and the conditionals in __get_vma_policy(). VMACACHE_HASH() determines which of the four per-task_struct slots a vma is cached for a particular address. This currently depends on the pfn, so pfn 5212 occupies a different vmacache slot than its neighboring pfn 5213. vmacache_find() iterates through all four of current's vmacache slots when looking up an address. Hashing based on pfn, an address has ~1/VMACACHE_SIZE chance of being cached in the first vmacache slot, or about 25%, *if* the vma is cached. This patch hashes an address by its pmd instead of pte to optimize for workloads with good spatial locality. This results in a higher probability of vmas being cached in the first slot that is checked: normally ~70% on the same workloads instead of 25%.

Provide list_lru_shrink_walk_irq() and let it behave like list_lru_walk_one() except that it locks the spinlock with spin_lock_irq(). This is used by scan_shadow_nodes() because its lock nests within the i_pages lock which is acquired with IRQ. This change allows to use proper locking promitives instead hand crafted lock_irq_disable() plus spin_lock(). There is no EXPORT_SYMBOL provided because the current user is in-kernel only. Add list_lru_shrink_walk_irq() which acquires the spinlock with the proper locking primitives. Link: http://lkml.kernel.org/r/20180716111921.5365-5-bigeasy@linutronix.deSigned-off-by:
