assign one as io port shortage.
The driver is only looking for MEM, and should not fail.
It turns out megasas_init_fw() etc are using bar index as mask. index 1
is used as mask 1, so that pci_request_selected_regions() is trying to
request BAR0 instead of BAR1.
Fix all related reference.

In aacraid's ioctl_send_fib() we do two fetches from userspace, one the
get the fib header's size and one for the fib itself. Later we use the
size field from the second fetch to further process the fib. If for some
reason the size from the second fetch is different than from the first
fix, we may encounter an out-of- bounds access in aac_fib_send(). We
also check the sender size to insure it is not out of bounds. This was
reported in https://bugzilla.kernel.org/show_bug.cgi?id=116751 and was
assigned CVE-2016-6480.

This crash is due to the AFU not being mapped when the shutdown
notification routine is called and is a regression that was inserted
recently with Commit 704c4b0ddc ("cxlflash: Shutdown notify support
for CXL Flash cards").
As a fix, shutdown notification should only occur when the AFU is
mapped.

drivers/scsi/lpfc/lpfc_attr.c:3064:1930: error: comparison of unsigned expression >= 0 is always true [-Werror=type-limits]
The code works as intended, but it would be nice to shut up the warning
so we don't clutter up build logs with this. Using a separate inline
function for it makes it clear to the compiler that the comparison is
necessary in the caller but still lets it do the constant-folding.

The SA controller spins down RAID drive spares.
A REGNEWD event causes an inquiry to be sent to all physical
drives. This causes the SA controller to spin up the spare.
The controller suspends all I/O to a logical volume until
the spare is spun up. The spin-up can take over 50 seconds.
This can result in one or both of the following:
- SML sends down aborts and resets to the logical volume
and can cause the logical volume to be off-lined.
- a negative impact on the logical volume's I/O performance
each time a REGNEWD is triggered.
