Subject: [PATCH v2 0/2]: Documentation/admin-guide: introduce
 perf-security.rst file and extend perf_event_paranoid documentation

To facilitate informed decision making by system administrators [1]
to permit and manage access to Perf Events (PE) / Perf tool (Perf) [2],[3] 
performance monitoring for multiple users perf-security.rst document 
suggested by Thomas Gleixner is introduced [4] that:

a) states PE/Perf access security concerns for multi user environment
b) refers to base Linux access control and management principles
c) extends documentation of possible perf_event_paranoid knob settings 

The file serves as single knowledge source for PE/Perf security and 
access control related matter according to decisions, discussion and  
PoC prototype previously made here [5],[6].

The file can later be extended with information describing:

a) PE/Perf usage models and its security implications
b) PE/Perf user interface, its changes and related security implications
c) security related implications of monitoring by a specific PE PMU [2]
