Juju Sung 94cd15bf22 lmkd: Remove redundant free swap and free memory check 
lmkd can't kill processes because it has compare the size between free swap and free memory. Free swap is often larger than the free memory when system is under low memory with less swap-backed or swappable pages and finally leads to I/O thrashing.

Pirama Arumuga Nainar f85d4216fd Make inlines static 
Bug: http://b/116873221

If not, building with coverage (and -O0) is broken since Clang does not
inline these functions, and does not emit a definition because they are
not static or extern.

Test: Build with coverage (-O0)

Greg Kaiser 584f3fd35f lmdk: Remove redundant 'if' check 
We already know that "polling" must be non-zero at this point,
because it hasn't been modified since our check on line 1960.
So we remove this check for code clarity.

Suren Baghdasaryan 55e3150842 lmkd: Add support for psi monitors 
With new psi monitor support in the kernel lmkd can use it to register
custom pressure levels. Add lmkd support for psi monitors when they are
provided by the kernel and use them by default. When kernel does not
support psi lmkd will fall back to vmpressure usage.
Add ability to poll memory status after the initial psi event is triggered
because kernel throttles psi memory pressure events to one per PSI tracking
window (currently set to 1sec). Current implementation polls every 200ms
for 1sec duration after the initial event is triggered.
If ro.lmk.use_psi is set to false psi logic will be disabled even when psi
is supported in kernel.
