Hi all,

After merging the tip tree, today's linux-next build (i386 defconfig)
failed like this:

arch/x86/events/intel/ds.c: In function 'intel_pmu_drain_arch_pebs':
arch/x86/events/intel/ds.c:2983:24: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
2983 | top = (void *)((u64)cpuc->pebs_vaddr +
| ^
arch/x86/events/intel/ds.c:2983:15: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
2983 | top = (void *)((u64)cpuc->pebs_vaddr +
| ^
cc1: all warnings being treated as errors
