percpu: improve percpu_alloc_percpu event trace
Add call_site, bytes_alloc and gfp_flags fields to the output of the
percpu_alloc_percpu ftrace event:
mkdir-4393 [001] 169.334788: percpu_alloc_percpu:
call_site=mem_cgroup_css_alloc+0xa6 reserved=0 is_atomic=0 size=2408 align=8
base_addr=0xffffc7117fc00000 off=402176 ptr=0x3dc867a62300 bytes_alloc=14448
gfp_flags=GFP_KERNEL_ACCOUNT
This is required to track memcg-accounted percpu allocations.
