In the syscall process, @f_count and @f_mod are frequently used, if

Hi,

The static pinning and mapping problem in VFIO and possible solutions

complicated software approaches
This patch follows the discussion here:

Now that all users have been converted, require the split_lock parameter
be passed to bit_spin_lock(), bit_spin_unlock() and variants. Use it
to track the lockdep state of each lock.

Kunpeng920's EHCI controller does not have SBRN register.
Reading the SBRN register when the controller driver is
initialized will get 0.
When rebooting the EHCI driver, ehci_shutdown() will be called.
if the sbrn flag is 0, ehci_shutdown() will return directly.
The sbrn flag being 0 will cause
Some types of EHCI controllers do not have SBRN registers.
By comparing the white list, the operation of reading the SBRN
registers is skipped.
Subsequent EHCI controller types without SBRN registers can be
directly added to the white list.
The current patch does not affect the drive function.
(1) Add a whitelist for EHCI devices without SBRN registers.
(2) Add Kunpeng920's EHCI device to the whitelist.
Changes in v3:
- Fix some code style issues.
- Update struct name.
Changes in v2:
- Fix some code style issues.
- Update function name.

NeilBrown noticed the same problem with bit spinlocks that I did,
but chose to solve it locally in the rhashtable implementation rather
than lift it all the way to the bit spin lock implementation. Convert
rhashtables to use split_locks.

pm_runtime_get_sync will increment pm usage counter even it failed.
Forgetting to putting operation will result in reference leak here.
Fix it by replacing it with pm_runtime_resume_and_get to keep usage
counter balanced.
