This patch fixes a crash on qla2x00_mailbox_command caused when the driver is on UNLOADING state and tries to call qla2x00_poll, which triggers a NULL pointer dereference. Signed-off-by: Rodrigo R.

If AHD_DEBUG is enabled and ahd_platform_alloc fails then ahd is set to null and the debug printk dereferences ahd when passing it to ahd_name. Fix this by moving the debug printk to before the call to ahd_platform_alloc where ahd is not null at that point.

This patch prevents driver from setting lower default speed of 1 GB/sec, if the switch does not support Get Port Speed Capabilities (GPSC) command. Setting this default speed results into much lower write performance for large sequential WRITE. This patch modifies driver to check for gpsc_supported flags and prevents driver from issuing MBC_SET_PORT_PARAM (001Ah) to set default speed of 1 GB/sec. If driver does not send this mailbox command, firmware assumes maximum supported link speed and will operate at the max speed.

'Commit cc27b735 ("PCI/portdrv: Turn off PCIe services during shutdown")' has been added to kernel to shutdown pending PCIe port service interrupts during reboot so that a newly started kexec kernel wouldn't observe pending interrupts. pcie_port_device_remove() is disabling the root port and switches by calling pci_disable_device() after all PCIe service drivers are shutdown. This has been found to cause crashes on HP DL360 Gen9 machines during reboot due to hpsa driver not clearing the bus master bit during the shutdown procedure by calling pci_disable_device(). Disable device as part of the shutdown sequence.

For one GFP_DMA32 does not actually work with kmalloc, as we only have GFP_DMA and GFP_KERNEL caches, but not GFP_DMA32. Second the memory is mapped using the proper DMA API anyway, which would include proper bounce buffering if needed by the device.

Pull cgroup updates from Tejun Heo: - For cpustat, cgroup has a percpu hierarchical stat mechanism which propagates up the hierarchy lazily. This contains commits to factor out and generalize the mechanism so that it can be used for other cgroup stats too. The original intention was to update memcg stats to use it but memcg went for a different approach, so still the only user is cpustat. The factoring out and generalization still make sense and it's likely that this can be used for other purposes in the future. - cgroup uses kernfs_notify() (which uses fsnotify()) to inform user space of certain events. A rate limiting mechanism is added. - Other misc changes. * 'for-4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: cgroup: css_set_lock should nest inside tasklist_lock rdmacg: Convert to use match_string() helper cgroup: Make cgroup_rstat_updated() ready for root cgroup usage cgroup: Add memory barriers to plug cgroup_rstat_updated() race window cgroup: Add cgroup_subsys->css_rstat_flush() cgroup: Replace cgroup_rstat_mutex with a spinlock cgroup: Factor out and expose cgroup_rstat_*() interface functions cgroup: Reorganize kernel/cgroup/rstat.c cgroup: Distinguish base resource stat implementation from rstat cgroup: Rename stat to rstat cgroup: Rename kernel/cgroup/stat.c to kernel/cgroup/rstat.c cgroup: Limit event generation frequency cgroup: Explicitly remove core interface files

Pull xfs updates from Darrick Wong: "New features this cycle include the ability to relabel mounted filesystems, support for fallocated swapfiles, and using FUA for pure data O_DSYNC directio writes. With this cycle we begin to integrate online filesystem repair and refactor the growfs code in preparation for eventual subvolume support, though the road ahead for both features is quite long. There are also numerous refactorings of the iomap code to remove unnecessary log overhead, to disentangle some of the quota code, and to prepare for buffer head removal in a future upstream kernel. Metadata validation continues to improve, both in the hot path veifiers and the online filesystem check code. I anticipate sending a second pull request in a few days with more metadata validation improvements. This series has been run through a full xfstests run over the weekend and through a quick xfstests run against this morning's master, with no major failures reported. Summary: - Strengthen inode number and structure validation when allocating inodes. - Reduce pointless buffer allocations during cache miss - Use FUA for pure data O_DSYNC directio writes - Various iomap refactorings - Strengthen quota metadata verification to avoid unfixable broken quota - Make AGFL block freeing a deferred operation to avoid blowing out transaction reservations when running complex operations - Get rid of the log item descriptors to reduce log overhead - Fix various reflink bugs where inodes were double-joined to transactions - Don't issue discards when trimming unwritten extents - Refactor incore dquot initialization and retrieval interfaces - Fix some locking problmes in the quota scrub code - Strengthen btree structure checks in scrub code - Rewrite swapfile activation to use iomap and support unwritten extents - Make scrub exit to userspace sooner when corruptions or cross-referencing problems are found - Make scrub invoke the data fork scrubber directly on metadata inodes - Don't do background reclamation of post-eof and cow blocks when the fs is suspended - Fix secondary superblock buffer lifespan hinting - Refactor growfs to use table-dispatched functions instead of long stringy functions - Move growfs code to libxfs - Implement online fs label getting and setting - Introduce online filesystem repair (in a very limited capacity) - Fix unit conversion problems in the realtime freemap iteration functions - Various refactorings and cleanups in preparation to remove buffer heads in a future release - Reimplement the old bmap call with iomap - Remove direct buffer head accesses from seek hole/data - Various bug fixes" * tag 'xfs-4.18-merge-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (121 commits) fs: use ->is_partially_uptodate in page_cache_seek_hole_data fs: remove the buffer_unwritten check in page_seek_hole_data fs: move page_cache_seek_hole_data to iomap.c xfs: use iomap_bmap iomap: add an iomap-based bmap implementation iomap: add a iomap_sector helper iomap: use __bio_add_page in iomap_dio_zero iomap: move IOMAP_F_BOUNDARY to gfs2 iomap: fix the comment describing IOMAP_NOWAIT iomap: inline data should be an iomap type, not a flag mm: split ->readpages calls to avoid non-contiguous pages lists mm: return an unsigned int from __do_page_cache_readahead mm: give the 'ret' variable a better name __do_page_cache_readahead block: add a lower-level bio_add_page interface xfs: fix error handling in xfs_refcount_insert() xfs: fix xfs_rtalloc_rec units xfs: strengthen rtalloc query range checks xfs: xfs_rtbuf_get should check the bmapi_read results xfs: xfs_rtword_t should be unsigned, not signed dax: change bdev_dax_supported() to support boolean returns ...

Commit 6870c016 ("scripts/faddr2line: show the code context") radically altered the output format of the faddr2line tool. And while the new list output format might have merit it broke my vim usage and was hard to read. Make the new format optional; using a '--list' argument and attempt to make the output slightly easier to read by adding a little whitespace to separate the different files and explicitly mark the line in question.

mempool_init()/bioset_init() require that the mempools/biosets be zeroed first; they probably should not _require_ this, but not allocating those structs with kzalloc is a fairly nonsensical thing to do (calling mempool_exit()/bioset_exit() on an uninitialized mempool/bioset is legal and safe, but only works if said memory was zeroed.)

Pull irq updates from Thomas Gleixner: - Consolidation of softirq pending: The softirq mask and its accessors/mutators have many implementations scattered around many architectures. Most do the same things consisting in a field in a per-cpu struct (often irq_cpustat_t) accessed through per-cpu ops. We can provide instead a generic efficient version that most of them can use. In fact s390 is the only exception because the field is stored in lowcore. - Support for level!?! triggered MSI (ARM) Over the past couple of years, we've seen some SoCs coming up with ways of signalling level interrupts using a new flavor of MSIs, where the MSI controller uses two distinct messages: one that raises a virtual line, and one that lowers it. The target MSI controller is in charge of maintaining the state of the line. This allows for a much simplified HW signal routing (no need to have hundreds of discrete lines to signal level interrupts if you already have a memory bus), but results in a departure from the current idea the kernel has of MSIs. - Support for Meson-AXG GPIO irqchip - Large stm32 irqchip rework (suspend/resume, hierarchical domains) - More SPDX conversions * 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (36 commits) ARM: dts: stm32: Add exti support to stm32mp157 pinctrl ARM: dts: stm32: Add exti support for stm32mp157c pinctrl/stm32: Add irq_eoi for stm32gpio irqchip irqchip/stm32: Add suspend/resume support for hierarchy domain irqchip/stm32: Add stm32mp1 support with hierarchy domain irqchip/stm32: Prepare common functions irqchip/stm32: Add host and driver data structures irqchip/stm32: Add suspend support irqchip/stm32: Add falling pending register support irqchip/stm32: Checkpatch fix irqchip/stm32: Optimizes and cleans up stm32-exti irq_domain irqchip/meson-gpio: Add support for Meson-AXG SoCs dt-bindings: interrupt-controller: New binding for Meson-AXG SoC dt-bindings: interrupt-controller: Fix the double quotes softirq/s390: Move default mutators of overwritten softirq mask to s390 softirq/x86: Switch to generic local_softirq_pending() implementation softirq/sparc: Switch to generic local_softirq_pending() implementation softirq/powerpc: Switch to generic local_softirq_pending() implementation softirq/parisc: Switch to generic local_softirq_pending() implementation softirq/ia64: Switch to generic local_softirq_pending() implementation ...
