Bug Fix(es):

* kernel crash when call the timer function
(sctp_generate_proto_unreach_event) of sctp module

* SCSI error handling process on HP P440ar controller gets stuck
indefinitely in device reset operation

* netfilter: reproducible deadlock on nft_log module autoload

* netfilter: NULL pointer dereference in nf_tables_set_lookup()

* [DELL EMC 7.9 Bug]: No acpi_pad threads on top command for "power cap
policy equal to 0 watts"

* A race between i40e_ndo_set_vf_mac() and i40e_vsi_clear() in the i40e
driver causes a use after free condition of the kmalloc-4096 slab cache.

* netxen driver performs poorly with RT kernel

* gendisk->disk_part_tbl->last_lookup retains pointer after partition
deletion

* Kernel experiences panic in update_group_power() due to division error
even with Bug 1701115 fix

* SL7.9 - zfcp: fix handling of FCP_RESID_OVER bit in fcp ingress path

* SL7.9 - mm/THP: do not access vma->vm_mm after calling handle_userfault

* raid: wrong raid io account

* qla2x00_status_cont_entry() missing upstream patch that prevents
unnecessary ABRT/warnings

* SL 7.9.z - System hang caused by workqueue stall in qla2xxx driver

* selinux: setsebool can trigger a deadlock

* [Hyper-V][SL-7] Cannot boot kernel 3.10.0-1160.21.1.el7.x86_64 on
Hyper-V
