To pick up the changes in:
a85cbe6159 ("uapi: move constants from <linux/kernel.h> to <linux/const.h>")
That causes no changes in tooling, just addresses this perf build
warning:
Warning: Kernel ABI header at 'tools/include/uapi/linux/const.h' differs from latest version at 'include/uapi/linux/const.h'
