Another week, another -rc.

Things have remained reasonably calm, although we also had a few
last-minute MM regressions. Happily, most of them got fixed really
quickly, with one remaining arm64 issue still pending.

So go forth and test some more. I'll be traveling for the next two
weeks due to LCA, but I should have internet, and if things continue
to be reasonably calm I don't think that my travel should be all that
noticeable.  Finally the timing worked out, unlike several releases
last year.

Anyway, the appended shortlog gives the details, but apart from the
kgdb patches showing up as some uncommon work under kernel/debug/,
things look fairly normal: mostly driver updates (gpu, pinctrl, hid,
networking), architecture updates (mainly x86 this time, some minor
arm[64] stuff), and some tooling fixes (mainly perf).

>       mm: propagate error from stack expansion even for guard page
hi,

the commit `mm: propagate error from stack expansion even for guard page'
changes the return value of check_stack_guard_page(). In do_anonymous_page(),
it only returns VM_FAULT_SIGBUS if check_stack_guard_page() gets error, and
this leads to the userspace tasks get `Bus error'.

But in the situation,
    int main(void)
    {
        main();
        return 0;
    }

the infinite recursion exceeds the stack limit, and it causes `segmentaion
fault' in older kernels. So shall we distinguish different return values
of check_stack_guard_page()?

thanks,
Sheng Yong
