Merge tag 'v6.15' into rdma.git for-next
Following patches need the RDMA rc branch since we are past the RC cycle
now.
Merge conflicts resolved based on Linux-next:
- For RXE odp changes keep for-next version and fixup new places that
need to call is_odp_mr()

https://lore.kernel.org/r/20250514122455.3593b083@canb.auug.org.au
- irdma is keeping the while/kfree bugfix from -rc and the pf/cdev_info
change from for-next
