The Socionext Synquacer SoC has an external interrupt unit (EXIU)
that forwards a block of 32 configurable input lines to 32 adjacent
level-high type GICv3 SPIs.
The EXIU has per-interrupt level/edge and polarity controls, and
mask bits that keep the outgoing lines de-asserted, even though
the controller may still latch interrupt conditions that occur
while the line is masked.

Replace ghes_io{re,un}map_pfn_{nmi,irq}()s use of ioremap_page_range()
with __set_fixmap() as ioremap_page_range() may sleep to allocate a new
level of page-table, even if its passed an existing final-address to
use in the mapping.
The GHES driver can only be enabled for architectures that select
HAVE_ACPI_APEI: Add fixmap entries to both x86 and arm64.
clear_fixmap() does the TLB invalidation in __set_fixmap() for arm64
and __set_pte_vaddr() for x86. In each case its the same as the
respective arch_apei_flush_tlb_one().

its_vpe_irq_domain_activate should always return 0. Really. There
is not a single case why it wouldn't. So this "return true;" is
really a copy/paste issue that got revealed now that we actually
check the return value of the activate method.

The newly added base_make_prp_nvme function triggers a build warning on
some 32-bit configurations:
drivers/scsi/mpt3sas/mpt3sas_base.c: In function 'base_make_prp_nvme':
drivers/scsi/mpt3sas/mpt3sas_base.c:1664:13: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
msg_phys = (dma_addr_t)mpt3sas_base_get_pcie_sgl_dma(ioc, smid);
After taking a closer look, I found that the problem is that the new
code mixes up pointers and dma_addr_t values unnecessarily.
This changes it to use the correct types consistently, which lets us get
rid of a lot of type casts in the process. I'm also renaming some
variables to avoid confusion between physical and dma address spaces
that are often distinct.

When there are multiple disks attached to the same SCSI controller, the
host may send several VSTOR_OPERATION_REMOVE_DEVICE or
VSTOR_OPERATION_ENUMERATE_BUS messages in a row, to indicate there is a
change on the SCSI controller. In response, storvsc rescans the SCSI
host.
There is no need to do multiple scans on the same host. Fix the code to
do only one scan.

We can end up sleeping for a while waiting for the dead timeout, which
means we could get the per request timer to fire. We did handle this
case, but if the dead timeout happened right after we submitted we'd
either tear down the connection or possibly requeue as we're handling an
error and race with the endio which can lead to panics and other
hilarity.

get_cpu_ptr() disabled preemption and returns the ->fq object of the
current CPU. raw_cpu_ptr() does the same except that it not disable
preemption which means the scheduler can move it to another CPU after it
obtained the per-CPU object.
In this case this is not bad because the data structure itself is
protected with a spin_lock. This change shouldn't matter however on RT
it does because the sleeping lock can't be accessed with disabled
preemption.

IPMMU instance data is the perfect place to keep track of a per-instance

We have two implementations for ipmmu_ops->alloc depending on
CONFIG_IOMMU_DMA, the difference being whether they accept the
IOMMU_DOMAIN_DMA type or not. However, iommu_dma_get_cookie() is
guaranteed to return an error when !CONFIG_IOMMU_DMA, so if
ipmmu_domain_alloc_dma() was actually checking and handling the return
value correctly, it would behave the same as ipmmu_domain_alloc()
anyway.
Similarly for freeing; iommu_put_dma_cookie() is robust by design.

Loopback has its own internal method for tracking and timing out
asynchronous operations however previous patches make it possible to use
functionality provided by operation.c to do this instead. Using the code in
operation.c means we can completely subtract the timer, the work-queue, the
kref and the cringe-worthy 'pending' flag. The completion callback
triggered by operation.c will provide an authoritative result code -
including -ETIMEDOUT for asynchronous operations.
