Init data marked const should be annotated with __initconst for
correctness and not __initdata. In some cases the array gathering
references to that data has to be marked const as well. This fixes
LTO builds that otherwise fail with section mismatch errors.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/cleanup
Merge "drop few more legacy boards for v4.3" from Tony Lindgren:
Drop more omap3 legacy board-*.c files for v4.3. This time we're
dropping the board files for omap3logic and omap3pandora.
The reason for dropping these now rather than later is that now
we can simply revert the patches in case of unexpected issues as
we are not dropping any platform data at this point.
This leaves us with only the following board-*.c files:
BOARD REASON NEEDED
board-ldp.c Still used in RMKs boot test system
board-rx51-*.c Needs /proc/atags support for user space
Once we have the n900 legacy user space issues sorted out for
/proc/atags and system_rev, we can drop the remaining two
board-*.c files. And then one merge window after that we can
drop the legacy booting support assuming no unexpected issues
are found.

Merge "EP93xx cleanups for v4.3" from Linus Walleij:
EP93xx cleanup and completing developments. This switches

Merge "ARM: clockevents: Migrate to 'set-state' callbacks" from Viresh Kumar:
This series migrates ARM clockevent drivers (present in arch/arm/
directory), to the new set-state interface. This would enable these
drivers to use new states (like: ONESHOT_STOPPED, etc.) of a clockevent
device (if required), as the set-mode interface is marked obsolete now
and wouldn't be expanded to handle new states.

We've been moving all omap2+ based systems to boot in device tree only
mode for a few years now. Only omap3 has legacy booting support
remaining. Most omap3 boards already have related arch/arm/boot/*.dts*
files for booting with device tree.
This board has support for device tree based booting, and we've been
printing warnings about the legacy booting being deprecated for a
few merge cycles now. Let's attempt to remove the legacy booting
for it.
The reason for removing the legacy booting support now rather than
later is we can simply revert this patch if necessary if we run
into some unexpected issues that are not trivial to fix for the
device tree based booting.

This reverts commit dec4f799d0a4c9edae20512fa60b0a36f3299ca2.
Jörg Otte reports a NULL pointder dereference due to this commit, as
'crtc_state' very much can be NULL:
crtc_state = state->base.state ?
intel_atomic_get_crtc_state(state->base.state, intel_crtc) : NULL;
So the change to test 'crtc_state->base.active' cannot possibly be
correct as-is.
There may be some other minimal fix (like just checking crtc_state for
NULL), but I'm just reverting it now for the rc2 release, and people
like Daniel Vetter who actually know this code will figure out what the
right solution is in the longer term.

Pull irq fix from Thomas Gleixner:
"A single fix for a cpu hotplug race vs. interrupt descriptors:
Prevent irq setup/teardown across the cpu starting/dying parts of cpu
hotplug so that the starting/dying cpu has a stable view of the
descriptor space. This has been an issue for all architectures in the
cpu dying phase, where interrupts are migrated away from the dying
cpu. In the starting phase its mostly a x86 issue vs the vector space
update"

Normally opening a file, unlinking it and then closing will have
the inode freed upon close() (provided that it's not otherwise busy and
has no remaining links, of course). However, there's one case where that
does *not* happen. Namely, if you open it by fhandle with cold dcache,
then unlink() and close().
In normal case you get d_delete() in unlink(2) notice that dentry
is busy and unhash it; on the final dput() it will be forcibly evicted from
dcache, triggering iput() and inode removal. In this case, though, we end
up with *two* dentries - disconnected (created by open-by-fhandle) and
regular one (used by unlink()). The latter will have its reference to inode
dropped just fine, but the former will not - it's considered hashed (it
is on the ->s_anon list), so it will stay around until the memory pressure
will finally do it in. As the result, we have the final iput() delayed
indefinitely. It's trivial to reproduce -
void flush_dcache(void)
{
system("mount -o remount,rw /");
}
static char buf[20 * 1024 * 1024];
main()
{
int fd;
union {
struct file_handle f;
char buf[MAX_HANDLE_SZ];
} x;
int m;
x.f.handle_bytes = sizeof(x);
chdir("/root");
mkdir("foo", 0700);
fd = open("foo/bar", O_CREAT | O_RDWR, 0600);
close(fd);
name_to_handle_at(AT_FDCWD, "foo/bar", &x.f, &m, 0);
flush_dcache();
fd = open_by_handle_at(AT_FDCWD, &x.f, O_RDWR);
unlink("foo/bar");
write(fd, buf, sizeof(buf));
system("df ."); /* 20Mb eaten */
close(fd);
system("df ."); /* should've freed those 20Mb */
flush_dcache();
system("df ."); /* should be the same as #2 */
}
will spit out something like
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/root 322023 303843 1131 100% /
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/root 322023 303843 1131 100% /
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/root 322023 283282 21692 93% /
- inode gets freed only when dentry is finally evicted (here we trigger
than by remount; normally it would've happened in response to memory
pressure hell knows when).

Pull libnvdimm fixes from Dan Williams:
"1) Fixes for a handful of smatch reports (Thanks Dan C.!) and minor
bug fixes (patches 1-6)
2) Correctness fixes to the BLK-mode nvdimm driver (patches 7-10).
Granted these are slightly large for a -rc update. They have been
out for review in one form or another since the end of May and were
deferred from the merge window while we settled on the "PMEM API"
for the PMEM-mode nvdimm driver (ie memremap_pmem, memcpy_to_pmem,
and wmb_pmem).
Now that those apis are merged we implement them in the BLK driver
to guarantee that mmio aperture moves stay ordered with respect to
incoming read/write requests, and that writes are flushed through
those mmio-windows and platform-buffers to be persistent on media.
These pass the sub-system unit tests with the updates to
tools/testing/nvdimm, and have received a successful build-report from
the kbuild robot (468 configs).
With acks from Rafael for the touches to drivers/acpi/"

With commit 02b4e2756e01c623cc4dbceae4b07be75252db5b ("ARM: v7 setup
function should invalidate L1 cache"), the default secondary_startup
function for ARMv7 CPUs does invalidate the L1 cache, which was the sole
reason why BCM63xx had to have its own secondary_startup implementation.
Now that the secondary_startup takes care of this, we can completely
remove that code.

of_get_cpu_node provides the device node associated with the given
logical CPU and cpu_logical_map contains the physical id for each CPU
in the logical ordering. Passing cpu_logical_map(cpu) to of_get_cpu_node
is incorrect.
This patch fixes the issue by passing the logical CPU number to
of_get_cpu_node
