Subject: [PATCH v3 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 (perf_events) / Perf tool 
(Perf) [2],[3] performance monitoring for multiple users perf-security.rst 
document suggested by Thomas Gleixner is introduced [4] that:

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