Subject: mm/page_alloc: remove obsolete gfpflags_normal_context()
Date: Fri, 16 Sep 2022 15:22:56 +0800
Since commit dacb5d8875cc ("tcp: fix page frag corruption on page fault"),
there's no caller of gfpflags_normal_context(). Remove it as this helper
is strictly tied to the sk page frag usage and there won't be other user
in the future.

- * An allocation being allowed to block doesn't mean it owns the %current
- * context. When direct reclaim path tries to allocate memory, the
- * allocation context is nested inside whatever %current was doing at the
- * time of the original allocation. The nested allocation may be allowed
- * to block but modifying anything %current owns can corrupt the outer
- * context's expectations.
- *
- * %true result from this function indicates that the allocation context
- * can sleep and use anything that's associated with %current.
