Pull strscpy string copy function implementation from Chris Metcalf.
Chris sent this during the merge window, but I waffled back and forth on
the pull request, which is why it's going in only now.
The new "strscpy()" function is definitely easier to use and more secure
than either strncpy() or strlcpy(), both of which are horrible nasty
interfaces that have serious and irredeemable problems.
strncpy() has a useless return value, and doesn't NUL-terminate an
overlong result. To make matters worse, it pads a short result with
zeroes, which is a performance disaster if you have big buffers.
strlcpy(), by contrast, is a mis-designed "fix" for strlcpy(), lacking
the insane NUL padding, but having a differently broken return value
which returns the original length of the source string. Which means
that it will read characters past the count from the source buffer, and
you have to trust the source to be properly terminated. It also makes
error handling fragile, since the test for overflow is unnecessarily
subtle.
strscpy() avoids both these problems, guaranteeing the NUL termination
(but not excessive padding) if the destination size wasn't zero, and
making the overflow condition very obvious by returning -E2BIG. It also
doesn't read past the size of the source, and can thus be used for
untrusted source data too.
So why did I waffle about this for so long?
Every time we introduce a new-and-improved interface, people start doing
these interminable series of trivial conversion patches.
And every time that happens, somebody does some silly mistake, and the
conversion patch to the improved interface actually makes things worse.
Because the patch is mindnumbing and trivial, nobody has the attention
span to look at it carefully, and it's usually done over large swatches
of source code which means that not every conversion gets tested.
So I'm pulling the strscpy() support because it *is* a better interface.
But I will refuse to pull mindless conversion patches. Use this in
places where it makes sense, but don't do trivial patches to fix things
that aren't actually known to be broken.
* 'strscpy' of git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile:
tile: use global strscpy() rather than private copy
string: provide strscpy()
Make asm/word-at-a-time.h available on all architectures

The MIPS syscall handler code used to return -ENOSYS on invalid
syscalls. Whilst this is expected, it caused problems for seccomp
filters because the said filters never had the change to run since
the code returned -ENOSYS before triggering them. This caused
problems on the chromium testsuite for filters looking for invalid
syscalls. This has now changed and the seccomp filters are always
run even if the syscall is invalid. We return -ENOSYS once we
return from the seccomp filters. Moreover, similar codepaths have
been merged in the process which simplifies somewhat the overall
syscall code.

m68k/defconfig: Update defconfigs for v4.3-rc1

m68k: Wire up direct socket calls
When configuring the interrupt mapping for a new device, we
iterate over all the possible aliases to account for their
maximum MSI allocation. This was introduced by e8137f4f50
("irqchip: gicv3-its: Iterate over PCI aliases to generate ITS configuration").
Turns out that the code doing that is a bit braindead, and repeatedly
accounts for the same device over and over.
Fix this by counting the actual alias that is passed to us by the
core code.

More agressive inlining in recent versions of GCC have uncovered
a new set of warnings:
drivers/irqchip/irq-gic-v3-its.c: In function its_msi_prepare:
drivers/irqchip/irq-gic-v3-its.c:1148:26: warning: lpi_base may be used
uninitialized in this function [-Wmaybe-uninitialized]
dev->event_map.lpi_base = lpi_base;
^
drivers/irqchip/irq-gic-v3-its.c:1116:6: note: lpi_base was declared here
int lpi_base;
^
drivers/irqchip/irq-gic-v3-its.c:1149:25: warning: nr_lpis may be used
uninitialized in this function [-Wmaybe-uninitialized]
dev->event_map.nr_lpis = nr_lpis;
^
drivers/irqchip/irq-gic-v3-its.c:1117:6: note: nr_lpis was declared here
int nr_lpis;
^
The warning is fairly benign (there is no code path that could
actually use uninitialized variables), but let's silence it anyway
by zeroing the variables on the error path.
