Created new attribute lpfc_enable_mi, which by default is enabled. Add command definition bits for SLI-4 parameters that recognize whether the adapter has MIB information support and what revision of MIB data. Using the adapter information, register vendor-specific MIB support with FDMI. The registration will be done every link up. During FDMI registration, encountered a couple of errors when reverting to FDMI rev1. Code needed to exist once reverting. Fixed these.

The driver supports arbitrarily large scatter-gather lists and the current value for max_sectors is limiting. Change max_sectors to the largest value. This was actually done prior but it only corrected one template and that template was later removed. So change the remaining 2 templates. Other areas which hard-set the sectors value should be inheriting what is in the template. Link: https://lore.kernel.org/r/20201020202719.54726-7-james.smart@broadcom.comSigned-off-by:

Commit 9816ef6e ("scsi: lpfc: Use after free in lpfc_rq_buf_free()") was made to correct a use after free condition in lpfc_rq_buf_free(). Unfortunately, a subsequent patch cut on a tree without the fix inadvertently reverted the fix. Put the fix back: Move the freeing of the rqb_entry to after the print function that references it.

The allocation is GFP_KERNEL, thus it could attempt to sleep. Fix by creating a work element that performs the event handling for the remote port. This will have the mailbox commands and other items performed in the work element, not the irq. A much better method as the "irq" routine does not stall while performing all this deep handling code. Ensure that allocation failures are handled and send LOGO on failure. Additionally, enlarge the mailbox memory pool to reduce the possibility of additional allocation in this path.

scatter_data_area() and gather_data_area() are not easy to understand since data is copied in nested loops over sg_list and tcmu dbi list. Since sg list can contain only partly filled pages, the loop has to be prepared to handle sg pages not matching dbi pages one by one. Existing implementation uses kmap_atomic()/kunmap_atomic() due to performance reasons. But instead of using these calls strictly nested for sg and dpi pages, the code holds the mappings in an overlapping way, which indeed is a bug that would trigger on archs using highmem. The scatterlist lib contains the sg_miter_start/_next/_stop functions which can be used to simplify such complicated loops. The new code now processes the dbi list in the outer loop, while sg list is handled by the inner one. That way the code can take advantage of the sg_miter_* family calls. Calling sg_miter_stop() after the end of the inner loop enforces strict nesting of atomic kmaps. Since the nested loops in scatter_/gather_data_area were very similar, I replaced them by the new helper function tcmu_copy_data().

Pull random32 updates from Willy Tarreau: "Make prandom_u32() less predictable. This is the cleanup of the latest series of prandom_u32 experimentations consisting in using SipHash instead of Tausworthe to produce the randoms used by the network stack. The changes to the files were kept minimal, and the controversial commit that used to take noise from the fast_pool (f227e3ec) was reverted. Instead, a dedicated "net_rand_noise" per_cpu variable is fed from various sources of activities (networking, scheduling) to perturb the SipHash state using fast, non-trivially predictable data, instead of keeping it fully deterministic. The goal is essentially to make any occasional memory leakage or brute-force attempt useless. The resulting code was verified to be very slightly faster on x86_64 than what is was with the controversial commit above, though this remains barely above measurement noise. It was also tested on i386 and arm, and build- tested only on arm64" Link: https://lore.kernel.org/netdev/20200808152628.GA27941@SDF.ORG/ * tag '20201024-v4-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/wtarreau/prandom: random32: add a selftest for the prandom32 code random32: add noise from network and scheduling activity random32: make prandom_u32() output unpredictable

Commit 21653a41 ("i2c: core: Call i2c_acpi_install_space_handler() before i2c_acpi_register_devices()")'s intention was to only move the acpi_install_address_space_handler() call to the point before where the ACPI declared i2c-children of the adapter where instantiated by i2c_acpi_register_devices(). But i2c_acpi_install_space_handler() had a call to acpi_walk_dep_device_list() hidden (that is I missed it) at the end of it, so as an unwanted side-effect now acpi_walk_dep_device_list() was also being called before i2c_acpi_register_devices(). Move the acpi_walk_dep_device_list() call to the end of i2c_acpi_register_devices(), so that it is once again called *after* the i2c_client-s hanging of the adapter have been created. This fixes the Microsoft Surface Go 2 hanging at boot.
