Hello,

On top of "[PATCH 0/3] uprobes: misc minor changes".

Sorry for delay. When I tried to test these changes, I hit the
bug report from bad_page(). However, it turns out this is another
unrelated problem, hopefully I'll send the fix soon. In short,
replace_page() is buggy.

Changes:

	- do not try GFP_NOWAIT if it failed before and more != 0,
	  this is pointless and wrong

	- update the comments (thanks Peter)

Oleg.
