[PATCH v3 0/2] Always show mmap prot even though PROT_NONE

[Changbin Du]

Before: PROT_NONE is not shown.
$ sudo perf trace -e syscalls:sys_enter_mmap --filter prot==0  -- ls
     0.000 ls/2979231 syscalls:sys_enter_mmap(len: 4220888, flags: PRIVATE|ANONYMOUS)

After: PROT_NONE is displayed.
$ sudo perf trace -e syscalls:sys_enter_mmap --filter prot==0  -- ls
     0.000 ls/2975708 syscalls:sys_enter_mmap(len: 4220888, prot: NONE, flags: PRIVATE|ANONYMOUS)
