This is a note to let you know that I've just added the patch titled
usb: host: xhci-plat: add a shutdown
to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch.
The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.
If you have any questions about this process, please let me know.

When loading new kernel via kexec, we need to shutdown host controller to avoid any un-expected memory accessing during new kernel boot.
