 FADump is supported on PowerNV platform. To fulfill this support, the
 petitboot kernel must be FADump aware. Enable config PRESERVE_FA_DUMP
 to make the petitboot kernel FADump aware.

-Subject: [PATCH 2/8] powerpc/opal: add MPIPL interface definitions
-
-MPIPL is Memory Preserving IPL supported from POWER9. This enables the
-kernel to reset the system with memory 'preserved'. Also, it supports
-copying memory from a source address to some destination address during
-MPIPL boot. Add MPIPL interface definitions here to leverage these f/w
-features in adding FADump support for PowerNV platform.
-
-This is the backport of upstream commit 6f5f193e84d3 ("powerpc/opal:
-add MPIPL interface definitions").

-
-The size parameter to fadump_reserve_crash_area() function is not needed
-as all the memory above boot memory size must be preserved anyway. Update
-the function by dropping this redundant parameter.
-
-This is the backport of upstream commit b2a815a554a3 ("powerpc/fadump:

-Subject: [PATCH 4/8] powerpc/fadump: add support to preserve crash data on
- FADUMP disabled kernel
-
-Add a new kernel config option, CONFIG_PRESERVE_FA_DUMP that ensures
-that crash data, from previously crash'ed kernel, is preserved. This
-helps in cases where FADump is not enabled but the subsequent memory
-preserving kernel boot is likely to process this crash data. One
-typical usecase for this config option is petitboot kernel.
-
-As OPAL allows registering address with it in the first kernel and
-retrieving it after MPIPL, use it to store the top of boot memory.
-A kernel that intends to preserve crash data retrieves it and avoids
-using memory beyond this address.
-
-Move arch_reserved_kernel_pages() function as it is needed for both
-FA_DUMP and PRESERVE_FA_DUMP configurations.
-
-This is the backport of upstream commit bec53196adf4 ("powerpc/fadump:
-add support to preserve crash data on FADUMP disabled kernel").
-
-Also, OPAL FADump metadata definition from upstream commit 742a265accd3
-("powerpc/fadump: register kernel metadata address with opal") is
-backported here for completeness.

-Subject: [PATCH 6/8] scsi: lpfc: Fix oops when fewer hdwqs than cpus
-
-When tearing down the adapter for a reset, online/offline, or driver
-unload, the queue free routine would hit a GPF oops.  This only occurs on
-conditions where the number of hardware queues created is fewer than the
-number of cpus in the system. In this condition cpus share a hardware
-queue. And of course, it's the 2nd cpu that shares a hardware that
-attempted to free it a second time and hit the oops.
-
-Fix by reworking the cpu to hardware queue mapping such that:
-Assignment of hardware queues to cpus occur in two passes:
-first pass: is first time assignment of a hardware queue to a cpu.
-  This will set the LPFC_CPU_FIRST_IRQ flag for the cpu.
-second pass: for cpus that did not get a hardware queue they will
-  be assigned one from a primary cpu (one set in first pass).
-
-Deletion of hardware queues is driven by cpu itteration, and queues
-will only be deleted if the LPFC_CPU_FIRST_IRQ flag is set.
-
-Also contains a few small cleanup fixes and a little better logging.

-Subject: [PATCH 7/8] scsi: lpfc: Limit xri count for kdump environment
-
-scsi-mq operation inherently performs pre-allocation of resources for
-blk-mq request queues. Even though the kdump environment reduces the
-configuration to a single CPU, thus 1 hardware queue, which helps
-significantly, the resources are still rather large due to the per request
-allocations. blk-mq pre-allocations can be over 4KB per request.  With
-adapter can_queue values in the 4k or 8k range, this can easily be 32MBs
-before any other driver memory is factored in.  Driver SGL DMA buffer
-allocation can be up to 8KB per request as well adding an additional
-64MB. Totals are well over 100MB for a single shost.  Given kdump memory
-auto-sizing utilities don't accommodate this amount of memory well, it's
-very possible for kdump to fail due to lack of memory.
-
-Fix by having the driver recognize that it is booting within a kdump
-context and reduce the number of requests it will support to a more
-reasonable value.
