The breakage is only with some compiler versions and some # hardware, and nobody seems to have figured out what triggers it, # although there's a simple reprodicer for the problem when it does # trigger. # # The problem was introduced with the conversion to the generic GUP code # in commit 7b9afb86b632 ("sparc64: use the generic get_user_pages_fast # code"), but nothing looks obviously wrong in that conversion. It may be # a compiler bug that just hits us with the code reorganization. Or it # may be something very specific to sparc64. # # This disables HAVE_FAST_GUP entirely. That makes things like futexes a # bit slower, but at least they work. If we can figure out the trigger, # that would be lovely, but it's been three months already.. # # Link: https://lore.kernel.org/lkml/20190717215956.GA30369@altlinux.org/ # Fixes: 7b9afb86b632
