drm/ttm: Use GFP_TRANSHUGE_LIGHT for allocating huge pages

2018-05-16T08:12:31Z

commit da291320baec914f0bb4e65a9dccb86bd6c728f2 upstream. GFP_TRANSHUGE tries very hard to allocate huge pages, which can result in long delays with high memory pressure. I have observed firefox freezing for up to around a minute due to this while restic was taking a full system backup. Since we don't really need huge pages, use GFP_TRANSHUGE_LIGHT | __GFP_NORETRY instead, in order to fail quickly when there are no huge pages available. Set __GFP_KSWAPD_RECLAIM as well, in order for huge pages to be freed up in the background if necessary. With these changes, I'm no longer seeing freezes during a restic backup.

A few more fixes for 4.16, nothing major. A few more fixes for 4.16. This is on top of the pull request from last week.
