Subject: [GIT PULL] hardening fixes for v6.5-rc2

Hi Linus,

Please pull this odd collection of hardening fixes for v6.5-rc2. I
included the somewhat unrelated sparc fix[1] since no one else had picked
it up yet, it was Acked, it had been pinged by the regression tracker,
and I was on CC. :)

Thanks!

-Kees
