sure - i have applied it to tip/out-of-tree. I'm equally nervous about 
this change - it affects every suspend+resume cycle that people do on 
those boxes which are working just fine currently.

btw., it would get a lot more coverage on my test-systems if this commit 
in tip/out-of-tree:

|     sleepy linux self-test

was upstream and if it was enabled more prominently, instead of hidden 
behind the rather obscure condition of:

  config PM_TEST_SUSPEND
        bool "Test suspend/resume and wakealarm during bootup"
        depends on SUSPEND && PM_DEBUG && RTC_LIB=y

and even then it needs certain other config options related to RTC_LIB 
to actually work during bootup.

As a result of all this obstruction, the automated testing i do, which 
builds and boots more than 1 random kernel per minute, will only run 
this self-test once every hour or so.

I dont mind if this option breaks boxes (that its purpose: it does the 
same thing that a real suspend+resume does and suspend+resume frequently 
breaks boxes), but right now it's all obscured so heavily which makes 
automated testing a lot harder than it should be.

it would be wonderful if this excellent suspend+resume self-test was 
upstream and was more prominent! :-)
