Hello,
This is a cleanup effort to get rid of useless arch_msi_check_device().
I am not sure what were the reasons for its existence in the first place,
but at the moment it appears totally unnecessary.
Thanks!

I plan to try get rid of arch_msi_check_device() hook. Should I repost

Currently the driver falls back to INTx mode when MSI-X

for chips that also support MSI. This update changes that

And x86 change is fairly small as well - all necessary functionality is

Thus, at the moment it is only AHCI of concern. And no, AHCI can not do MSI-X..

Function pci_enable_msix_exact() is a variation of
pci_enable_msix_range() that allows a device driver
to request a particular number of MSI-X interrupts,
rather than any number within a specified range.

This update partially reverts commit c5dc919 ("NVMe: Disable
admin queue on init failure") to roll back easy readable
nvme_free_queues() function. Commit's c5dc919 functionality
aimed to free admin queue IRQ on init failure is preserved.
