Subject: [PATCH v2 0/2] gup.c, gup_benchmark.c trivial fixes before the storm

Hi,

Changes since v1:

1) Fixed a krobot-reported mistake, which also uncovered a pre-existing
bug. Thanks to Kirill for recommending the fix.

2) Added another small fix: changed the data type to unsigned int, as
pointed out by Ira.

2) Added a "Fixes:" line, thanks to Kirill and Aneesh for pinpointing the
commit.

3) Collected Acked-by and Suggested-by's.

Original cover letter, edited slightly
======================================

These trivial fixes apply to today's linux.git (5.4-rc3).

I found these while polishing up the Next And Final get_user_pages()+dma
tracking patchset (which is in final testing and passing nicely...so far).

Anyway, as these two patches apply cleanly both before and after the larger
gup/dma upcoming patchset, I thought it best to send this out separately,
in order to avoid muddying the waters more than usual.
