6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Long Li <longli@xxxxxxxxxxxxx> commit 4a3b99bc04e501b816db78f70064e26a01257910 upstream. When mapping doorbell page from user-mode, the driver should use the system page size as this memory is allocated via mmap() from user-mode.
