(Adding linux-kernel to the distribution.  The issue seems to be
architecture-specific, but I'm trying to understand what broke.)

The 4.10-rc1 patch set made fairly extensive modifications to
"a/kernel/module.c" (I'm leaving the "a" there so there's no doubt I
mean the top-level "kernel/module.c" file and not any of the
architecture-specific ones).

One of the changes was to replace an include of <asm/uaccess.h> with
<linux/uaccess.h>.  This is potentially significant because of the
mod we made to alpha's <asm/uaccess.h> to fix the BRSGP relocation
error on __copy_user() issue.

Bottom line is, no kernel I've built since 4.9 can load a module.  All
attempts to load a module result in the error message emitted by
"arch/alpha/kernel/module.c" as follows:

module XXX: Unknown relocation: 1

I'll start attempting to revert the recent module patches to see if that
helps.  If anyone reading this knows what's happening, feel free to
weigh-in before I spend too much time rebuilding kernels on a slow
machine.
