git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc fixes from Helge Deller:
- The majority of lines changed are due to regenerated defconfig files.
- The support for the Page Deallocation Table (PDT) which was merged in
the merge window for 4.13 contained a bug which crashes the kernel if
a bad page is reported by firmware. This is now fixed and the kernel
messages will show which memory slot holds the broken DIMM.
- Commit 3a166fc2d4ef ("kbuild: handle libs-y archives separately from
built-in.o archives") broke linking the parisc kernel due to
millicode symbols which can't be reached then any longer. This was
fixed by modifying the parisc vmlinux.lds linker script.
- If the stack checker panics on stack overflow, avoid recursive
panics.
- Some parisc machines can't physically power off and thus instead
start after some time to flood the console by presumably detected
soft lockups. Avoid this by disabling the lockup detectors before
entering the endless for-next loop.
- Dave Anglin provided fixes which prevents TLB speculation on flushed
pages on PA8800/PA9000 CPUs.
- Arvind Yadav sent a trivial patch to constify the attribute_group
structure in our firmware on-board-flash storage driver
(pdc_stable.c)

Instead of fiddling with masking the event channels during suspend
and resume handling let do the irq subsystem do its job. It will do
the mask and unmask operations as needed.

Remove unnecessary static on local variables last_frontswap_pages and
tgt_frontswap_pages. Such variables are initialized before being used,
on every execution path throughout the function. The statics have no
benefit and, removing them reduce the code size.

posix_fallocate() will allocate space in an NFS file by considering
the last byte of every 4K block. If it is before EOF, it will read
the byte and if it is zero, a zero is written out. If it is after EOF,
the zero is unconditionally written.
For the blocks beyond EOF, if NFS believes its cache is valid, it will
expand these writes to write full pages, and then will merge the pages.
This results if (typically) 1MB writes. If NFS believes its cache is
not valid (particularly if NFS_INO_INVALID_DATA or
NFS_INO_REVAL_PAGECACHE are set - see nfs_write_pageuptodate()), it will
send the individual 1-byte writes. This results in (typically) 256 times
as many RPC requests, and can be substantially slower.
Currently nfs_revalidate_mapping() is only used when reading a file or
mmapping a file, as these are times when the content needs to be
up-to-date. Writes don't generally need the cache to be up-to-date, but
writes beyond EOF can benefit, particularly in the posix_fallocate()
case.
So this patch calls nfs_revalidate_mapping() when writing beyond EOF -
i.e. when there is a gap between the end of the file and the start of
the write. If the cache is thought to be out of date (as happens after
taking a file lock), this will cause a GETATTR, and the two flags
mentioned above will be cleared. With this, posix_fallocate() on a
newly locked file does not generate excessive tiny writes.

Prior to commit ca0daa277aca ("NFS: Cache aggressively when file is open
for writing"), NFS would revalidate, or invalidate, the file size when
taking a lock. Since that commit it only invalidates the file content.
If the file size is changed on the server while wait for the lock, the
client will have an incorrect understanding of the file size and could
corrupt data. This particularly happens when writing beyond the
(supposed) end of file and can be easily be demonstrated with
posix_fallocate().
If an application opens an empty file, waits for a write lock, and then
calls posix_fallocate(), glibc will determine that the underlying
filesystem doesn't support fallocate (assuming version 4.1 or earlier)
and will write out a '0' byte at the end of each 4K page in the region
being fallocated that is after the end of the file.
NFS will (usually) detect that these writes are beyond EOF and will
expand them to cover the whole page, and then will merge the pages.
Consequently, NFS will write out large blocks of zeroes beyond where it
thought EOF was. If EOF had moved, the pre-existing part of the file
will be over-written. Locking should have protected against this,
but it doesn't.
This patch restores the use of nfs_zap_caches() which invalidated the
cached attributes. When posix_fallocate() asks for the file size, the
request will go to the server and get a correct answer.

Current logic uses this value only if the mode is active-backup.
However, LACP mode, although considered a load balancing mode, can mark
a slave as inactive in certain situations (e.g., LACP timeout).
This fix takes the tx_enabled value into account when remapping, with
no respect to the LAG mode (this should not affect the behavior in XOR
mode, since in this mode both slaves are marked as active).

That commit was part of the changes moving x86 to the generic CPU hotplug
interrupt migration code. The force flag was required on x86 before the
hierarchical irqdomain rework, but invoking set_affinity() with force=true
stayed and had no side effects.
At some point in the past, the force flag got repurposed to support the
exynos timer interrupt affinity setting to a not yet online CPU, so the
interrupt controller callback does not verify the supplied affinity mask
against cpu_online_mask.
Setting the flag in the CPU hotplug code causes the cpu online masking to
be blocked on these irq controllers and results in potentially affining an
interrupt to the CPU which is unplugged, i.e. instead of moving it away,
it's just reassigned to it.
As the force flags is not longer needed on x86, it's safe to revert that
patch so the ARM irqchips which use the force flag work again.
Add comments to that effect, so this won't happen again.
Note: The online mask handling should be done in the generic code and the
force flag and the masking in the irq chips removed all together, but
that's not a change possible for 4.13.

Since the PMU register interface is banked per CPU, CPU PMU interrrupts
cannot be handled by a CPU other than the one with the PMU asserting the
interrupt. This means that migrating PMU SPIs, as we do during a CPU
hotplug operation doesn't make any sense and can lead to the IRQ being
disabled entirely if we route a spurious IRQ to the new affinity target.
This has been observed in practice on AMD Seattle, where CPUs on the
non-boot cluster appear to take a spurious PMU IRQ when coming online,
which is routed to CPU0 where it cannot be handled.
This patch passes IRQF_PERCPU for PMU SPIs and forcefully sets their
affinity prior to requesting them, ensuring that they cannot
be migrated during hotplug events. This interacts badly with the DB8500
erratum workaround that ping-pongs the interrupt affinity from the handler,
so we avoid passing IRQF_PERCPU in that case by allowing the IRQ flags
to be overridden in the platdata.

sa1100 provides its own variant of the clk API rather than using the
generic COMMON_CLK API. This generally works, but it causes some link
errors with drivers using the clk_set_rate, clk_get_parent, clk_set_parent
or clk_round_rate functions when a platform lacks those interfaces.
This adds trivial stub implementations for each of them, based on
the behavior of the COMMON_CLK implementation:
- set_rate() and set_parent() report success without doing anything
- round_rate() returns the clk rate
- get_parent() returns NULL.
This adds the minimal bloat and should do the right thing for
the simple clock hardware in this SoC.

On PXA, the IRQ register definitions were removed even earlier, in
commit 5d284e353eb1 ("ARM: pxa: avoid accessing interrupt registers
directly"). This patch unfortunately brings some of that back. An
earlier version of my patch moved the code into an external function,
which could not work for CONFIG_XIP_KERNEL+CONFIG_MTD_XIP, so this
restores something close to the original code.

The commit to rework the headroom check in start_xmit() now calls
pxskb_expand_head() unconditionally if the header is CoW. Unfortunately,
it does so with the delta between the extant headroom and the header
length, which may be negative if there is already sufficient headroom.
pskb_expand_head() does allow for size being 0, in which case it just
copies, so clamp the header delta to zero.

Add necessary parent clocks for audss (Audio SubSystem, MAUDIO) clock
controller block.
This allows driver to keep EPLL enabled before accessing any MAUDIO
registers thus fixing silent hang. This silent hang appeared with
commit 6edfa11cb396 ("clk: samsung: Add enable/disable operation for
PLL36XX clocks"), e.g. on Odroid U3 usually with last (but unrelated)
messages:

Pull "Second Round of Renesas ARM Based SoC Fixes for v4.13" from Simon Horman:
Correct order of sound clock frequencies for ULCB boards
used by r8a7795 and r8a7796 SoCs.
These sounds clock frequencies are used as the ADG clock (output clocks
for audio module) initial setting and sound codec's initial system clock
which needs the maximum clock frequency. Thus, descending order is
required.

Turns out that just writing CURPOS isn't sufficient to move the cursor
on some platforms. My 830 works just fine, but eg. 945 and PNV don't.
On those platforms we need to arm even the CURPOS update with a
CURBASE write.
Even worse, a write to any of the cursor register apart from CURBASE
will cancel an already pending cursor update. So if we have armed a
CURCNTR/CURBASE update, a subsequent CURPOS write prior to vblank
would cancel that armed update. Thus we're left with a cursor that
doesn't appear to move, or even change shape.
Fix the problem by always performing the CURBASE write after a
CURPOS write. Bspec is somewhat unclear which platforms actually
require this CURBASE write and which don't. So to keep it simple
and to make sure we really fix the problem across all supported
devices, let's just perform the CURBASE write unconditionally.
